-# Helpers for defining environment variables for CircleCI.
-#
-# In CircleCI, each step runs in a new shell. The way to share ENV variables across steps is to
-# export them from `$BASH_ENV`, which is automatically sourced at the beginning of every step (for
-# the default `bash` shell).
-#
-# See also https://circleci.com/docs/2.0/env-vars/#using-bash_env-to-set-environment-variables.
-####################################################################################################
-
-# Set and print an environment variable.
-#
-# Use this function for setting environment variables that are public, i.e. it is OK for them to be
-# visible to anyone through the CI logs.
-#
-# Usage: `setPublicVar <name> <value>`
-function setPublicVar() {
-  setSecretVar $1 "$2";
-  echo "$1=$2";
-}
-
-# Set (without printing) an environment variable.
-#
-# Use this function for setting environment variables that are secret, i.e. should not be visible to
-# everyone through the CI logs.
-#
-# Usage: `setSecretVar <name> <value>`
-function setSecretVar() {
-  # WARNING: Secrets (e.g. passwords, access tokens) should NOT be printed.
-  # (Keep original shell options to restore at the end.)
-  local -r originalShellOptions=$(set +o);
-  set +x -eu -o pipefail;
-
-  echo "export $1=\"${2:-}\";" >> $BASH_ENV;
-
-  # Restore original shell options.
-  eval "$originalShellOptions";
-}
-
-
-# Create a function to set an environment variable, when called.
-#
-# Use this function for creating setter for public environment variables that require expensive or
-# time-consuming computaions and may not be needed. When needed, you can call this function to set
-# the environment variable (which will be available through `$BASH_ENV` from that point onwards).
-#
-# Arguments:
-# - `<name>`: The name of the environment variable. The generated setter function will be
-#   `setPublicVar_<name>`.
-# - `<code>`: The code to run to compute the value for the variable. Since this code should be
-#   executed lazily, it must be properly escaped. For example:
-#   ```sh
-#   # DO NOT do this:
-#   createPublicVarSetter MY_VAR "$(whoami)";  # `whoami` will be evaluated eagerly
-#
-#   # DO this isntead:
-#   createPublicVarSetter MY_VAR "\$(whoami)";  # `whoami` will NOT be evaluated eagerly
-#   ```
-#
-# Usage: `createPublicVarSetter <name> <code>`
-#
-# Example:
-# ```sh
-# createPublicVarSetter MY_VAR 'echo "FOO"';
-# echo $MY_VAR;  # Not defined
-#
-# setPublicVar_MY_VAR;
-# source $BASH_ENV;
-# echo $MY_VAR;  # FOO
-# ```
-function createPublicVarSetter() {
-  echo "setPublicVar_$1() { setPublicVar $1 \"$2\"; }" >> $BASH_ENV;

 ## Angular CLI: Static Analysis errors (v1)

 ```
 Hello, errors like `Error encountered resolving symbol values statically` mean that there has been some problem in statically analyzing your app.
 
 Angular CLI always runs *some* static analysis, even in JIT mode, in order to discover lazy-loaded routes.
 This may cause a lot of static analysis errors to surface when importing your project into the CLI, or upgrading for older versions where we didn't run this kind of analysis.

 ## Angular CLI: Lockfiles (v1)

 ```
 I'd like to remind everyone that **you only have reproducible installs if you use a lockfile**. Both [NPM v5+](https://docs.npmjs.com/files/package-locks) and [Yarn](https://yarnpkg.com/lang/en/docs/yarn-lock/) support lockfiles. If your CI works one day but not the next and you did not change your code or `package.json`, it is likely because one of your dependencies had a bad release and you did not have a lockfile.

+
+## Breaking Changes
+
+### @angular/cli
+
+- Node.js v18 is no longer supported with Angular.
+
+  Before updating a project to Angular v20, the Node.js version must be
+  at least 20.11.1. For the full list of supported Node.js versions,
+  see https://angular.dev/reference/versions.
+
+### @angular-devkit/schematics
+
+- The `NodePackageLinkTask` has been removed without a replacement. Create a custom task if needed.
+
+  Note: This does not affect application developers.

+## Deprecations
+
+### @angular/build
+
+- The `baseHref` option under `i18n.locales` and `i18n.sourceLocale` in `angular.json` is deprecated in favor of `subPath`.
+
+  The `subPath` defines the URL segment for the locale, serving as both the HTML base HREF and the directory name for output. By default, if not specified, `subPath` will use the locale code.

+
+## Breaking Changes
+
+### @schematics/angular
+
+- The app-shell schematic is no longer compatible with Webpack-based builders.
+
+### @angular-devkit/build-angular
+
+- The `browserTarget` option has been removed from the DevServer and ExtractI18n builders. `buildTarget` is to be used instead.
+- Protractor is no longer supported.
+
+  Protractor was marked end-of-life in August 2023 (see https://protractortest.org/). Projects still relying on Protractor should consider migrating to another E2E testing framework, several support solid migration paths from Protractor.
+
+  - https://angular.dev/tools/cli/end-to-end
+  - https://blog.angular.dev/the-state-of-end-to-end-testing-with-angular-d175f751cb9c
+
+### @angular-devkit/core
+
+- The deprecated `fileBuffer` function is no longer available. Update your code to use `stringToFileBuffer` instead to maintain compatibility.
+
+  **Note:** that this change does not affect application developers.
+
+### @angular/build
+
+- The `@angular/localize/init` polyfill will no longer be added automatically to projects. To prevent runtime issues, ensure that this polyfill is manually included in the "polyfills" section of your "angular.json" file if your application relies on Angular localization features.
+
+### @angular/ssr
+
+- The `CommonEngine` API now needs to be imported from `@angular/ssr/node`.
+
+  **Before**
+
+  ```ts
+  import { CommonEngine } from '@angular/ssr';
+  ```
+
+  **After**
+
+  ```ts
+  import { CommonEngine } from '@angular/ssr/node';
+  ```

+# 18.0.0 (2024-05-22)
+
+## Breaking Changes
+
+### @angular/cli
+
+- The `ng doc` command has been removed without a replacement. To perform searches, please visit www.angular.dev
+- Node.js support for versions <18.19.1 and <20.11.1 has been removed.
+
+### @angular-devkit/build-angular
+
+- By default, the index.html file is no longer emitted in the browser directory when using the application builder with SSR. Instead, an index.csr.html file is emitted. This change is implemented because in many cases server and cloud providers incorrectly treat the index.html file as a statically generated page. If you still require the old behavior, you can use the `index` option to specify the `output` file name.
+
+  ```json
+  "architect": {
+    "build": {
+      "builder": "@angular-devkit/build-angular:application",
+      "options": {
+        "outputPath": "dist/my-app",
+        "index": {
+          "input": "src/index.html",
+          "output": "index.html"
+        }
+      }
+    }
+  }
+  ```
+
+- The support for the legacy Sass build pipeline, previously accessible via `NG_BUILD_LEGACY_SASS` when utilizing webpack-based builders, has been removed.
+
+## Deprecations
+
+### @angular-devkit/schematics
+
+- `NodePackageLinkTask` in `@angular-devkit/schematics`. A custom task should be created instead.

+
+# 16.0.0 (2023-05-03)
+
+## Breaking Changes
+
+### @angular/cli
+
+- The deprecated `defaultCollection` workspace option has been removed. Use `schematicCollections` instead.
+
+  Before
+
+  ```json
+  "defaultCollection": "@angular/material"
+  ```
+
+  After
+
+  ```json
+  "schematicCollections": ["@angular/material"]
+  ```
+
+- The deprecated `defaultProject` workspace option has been removed. The project to use will be determined from the current working directory.
+- Node.js v14 support has been removed
+
+  Node.js v14 is planned to be End-of-Life on 2023-04-30. Angular will stop supporting Node.js v14 in Angular v16.
+  Angular v16 will continue to officially support Node.js versions v16 and v18.
+
+### @schematics/angular
+
+- `ng g resolver` and `ng g guard` now generate a functional resolver or guard by default. It is still possible to generate a (deprecated) class-based resolver or guard by using `ng g resolver --no-functional` or `ng g guard --no-functional`.
+- The CLI no longer allows to generate `CanLoad` guards. Use `CanMatch` instead.
+
+###
+
+- - TypeScript 4.8 is no longer supported.
+
+### @angular-devkit/build-angular
+
+- Deprecated `outputPath` and `outputPaths` from the server and browser builder have been removed from the builder output. Use `outputs` instead.
+
+  Note: this change does not effect application developers.
+
+### @angular-devkit/core
+
+- Several changes to the `SchemaRegistry`.
+  - `compile` method now returns a `Promise`.
+  - Deprecated `flatten` has been removed without replacement.
+- - `ContentHasMutatedException`, `InvalidUpdateRecordException`, `UnimplementedException` and `MergeConflictException` API from `@angular-devkit/core` have been removed in favor of the API from `@angular-devkit/schematics`.
+  - `UnsupportedPlatformException` - A custom error exception should be created instead.
+
+### @angular-devkit/schematics
+
+- The depracated `UpdateBuffer` has been removed and `UpdateBuffer2`
+  is renamed to `UpdateBuffer`. With this change the related and
+  deprecated symbols `ContentCannotBeRemovedException` and `Chunk`
+  have also been removed.
+
+### @ngtools/webpack
+
+- NGCC integration has been removed and as a result Angular View Engine libraries will no longer work.
+

+
+# 15.0.0 (2022-11-16)
+
+## Breaking Changes
+
+### @angular/cli
+
+- The Angular CLI no longer supports `16.10.x`, `16.11.x` and `16.12.x`. Current minimum versions of Node.js are `14.20.0`, `16.13.0` and `18.10.0`.
+- Node.js versions older than 14.20 are no longer supported.
+- The 'path' option in schematics schema no longer has a special meaning. Use 'workingDirectory' smart default provider should be used instead.
+
+### @schematics/angular
+
+- Removed unused `appDir` option from Universal and App-Shell schematic. This option can safely be removed if present since it no longer has effect.
+
+###
+
+- `analyticsSharing` option in the global angular configuration has been
+  removed without replacement. This option was used to configure the Angular CLI to access to your own users' CLI usage data.
+
+  If this option is used, it can be removed using `ng config --global cli.analyticsSharing undefined`.
+
+- analytics APIs have been removed without replacement from `@angular-devkit/core` and `@angular-devkit/architect`.
+
+### @angular-devkit/build-angular
+
+- TypeScript versions older than 4.8.2 are no longer supported.
+- The server builder `bundleDependencies` option has been removed. This option was used pre Ivy. Currently, using this option is unlikely to produce working server bundles.
+
+  The `externalDependencies` option can be used instead to exclude specific node_module packages from the final bundle.
+
+- - Deprecated support for tilde import has been removed. Please update the imports by removing the `~`.
+
+  Before
+
+  ```scss
+  @import 'http://github.com/~font-awesome/scss/font-awesome';
+  ```
+
+  After
+
+  ```scss
+  @import 'http://github.com/font-awesome/scss/font-awesome';
+  ```
+
+  - By default the CLI will use Sass modern API, While not recommended, users can still opt to use legacy API by setting `NG_BUILD_LEGACY_SASS=1`.
+
+- Internally the Angular CLI now always set the TypeScript `target` to `ES2022` and `useDefineForClassFields` to `false` unless the target is set to `ES2022` or later in the TypeScript configuration. To control ECMA version and features use the Browerslist configuration.
+- `require.context` are no longer parsed. Webpack specific features are not supported nor guaranteed to work in the future.
+- Producing ES5 output is no longer possible. This was needed for Internet Explorer which is no longer supported. All browsers that Angular supports work with ES2015+
+- server builder `bundleDependencies` option now only accept a boolean value.
+- Deprecated support for Stylus has been removed. The Stylus package has never reached a stable version and its usage in the Angular CLI is minimal. It's recommended to migrate to another CSS preprocessor that the Angular CLI supports.
+
+### @angular-devkit/core
+
+- Workspace projects with missing `root` is now an error.
+
+### @ngtools/webpack
+
+- TypeScript versions older than 4.8.2 are no longer supported.
+
+### @schematics/angular

+
+# 14.0.0 (2022-06-02)
+
+## Breaking Changes
+
+### @angular/cli
+
+- Several changes to the `ng analytics` command syntax.
+
+  - `ng analytics project <setting>` has been replaced with `ng analytics <setting>`
+  - `ng analytics <setting>` has been replaced with `ng analytics <setting> --global`
+
+- Support for Node.js v12 has been removed as it will become EOL on 2022-04-30. Please use Node.js v14.15 or later.
+- Support for TypeScript 4.4 and 4.5 has been removed. Please update to TypeScript 4.6.
+- `--all` option from `ng update` has been removed without replacement. To update packages which don’t provide `ng update` capabilities in your workspace `package.json` use `npm update`, `yarn upgrade-interactive` or `yarn upgrade` instead.
+- Deprecated option `--prod` has been removed from all builders. `--configuration production`/`-c production` should be used instead if the default configuration of the builder is not configured to `production`.
+- `--configuration` cannot be used with `ng run`. Provide the configuration as part of the target. Ex: `ng run project:builder:configuration`.
+- Deprecated `ng x18n` and `ng i18n-extract` commands have been removed in favor of `ng extract-i18n`.
+- Several changes in the Angular CLI commands and arguments handling.
+
+  - `ng help` has been removed in favour of the `—-help` option.
+  - `ng —-version` has been removed in favour of `ng version` and `ng v`.
+  - Deprecated camel cased arguments are no longer supported. Ex. using `—-sourceMap` instead of `—-source-map` will result in an error.
+  - `ng update`, `—-migrate-only` option no longer accepts a string of migration name, instead use `—-migrate-only -—name <migration-name>`.
+  - `—-help json` help has been removed.
+
+### @angular-devkit/architect-cli
+
+- camel case arguments are no longer allowed.
+
+### @angular-devkit/schematics-cli
+
+- camel case arguments are no longer allowed.
+
+### @angular-devkit/build-angular
+
+- `browser` and `karma` builders `script` and `styles` options input files extensions are now validated.
+
+  Valid extensions for `scripts` are:
+
+  - `.js`
+  - `.cjs`
+  - `.mjs`
+  - `.jsx`
+  - `.cjsx`
+  - `.mjsx`
+
+  Valid extensions for `styles` are:
+
+  - `.css`
+  - `.less`
+  - `.sass`
+  - `.scss`
+  - `.styl`
+
+- We now issue a build time error since importing a CSS file as an ECMA module is non standard Webpack specific feature, which is not supported by the Angular CLI.
+
+  This feature was never truly supported by the Angular CLI, but has as such for visibility.
+
+- Reflect metadata polyfill is no longer automatically provided in JIT mode
+  Reflect metadata support is not required by Angular in JIT applications compiled by the CLI.
+  Applications built in AOT mode did not and will continue to not provide the polyfill.
+  For the majority of applications, the reflect metadata polyfill removal should have no effect.
+  However, if an application uses JIT mode and also uses the previously polyfilled reflect metadata JavaScript APIs, the polyfill will need to be manually added to the application after updating.
+  To replicate the previous behavior, the `core-js` package should be manually installed and the `import 'core-js/proposals/reflect-metadata';` statement should be added to the application's `polyfills.ts` file.
+- `NG_BUILD_CACHE` environment variable has been removed. `cli.cache` in the workspace configuration should be used instead.
+- The deprecated `showCircularDependencies` browser and server builder option has been removed. The recommended method to detect circular dependencies in project code is to use either a lint rule or other external tools.
+
+### @angular-devkit/core
+
+- `parseJson` and `ParseJsonOptions` APIs have been removed in favor of 3rd party JSON parsers such as `jsonc-parser`.
+- The below APIs have been removed without replacement. Users should leverage other Node.js or other APIs.
+  - `fs` namespace
+  - `clean`
+  - `mapObject`
+
+### @angular-devkit/schematics
+
+- Schematics `NodePackageInstallTask` will not execute package scripts by default
+  The `NodePackageInstallTask` will now use the package manager's `--ignore-scripts` option by default.
+  The `--ignore-scripts` option will prevent package scripts from executing automatically during an install.
+  If a schematic installs packages that need their `install`/`postinstall` scripts to be executed, the
+  `NodePackageInstallTask` now contains an `allowScripts` boolean option which can be enabled to provide the
+  previous behavior for that individual task. As with previous behavior, the `allowScripts` option will
+  prevent the individual task's usage of the `--ignore-scripts` option but will not override the package
+  manager's existing configuration.
+- Deprecated `analytics` property has been removed from `TypedSchematicContext` interface
+
+### @ngtools/webpack
+
+- `ivy` namespace has been removed from the public API.
+
+  - `ivy.AngularWebpackPlugin` -> `AngularWebpackPlugin`
+  - `ivy.AngularPluginOptions` -> `AngularPluginOptions`
+
+## Deprecations
+
+### @angular/cli
+
+- The `defaultCollection` workspace option has been deprecated in favor of `schematicCollections`.
+
+  Before
+
+  ```json
+  "defaultCollection": "@angular/material"
+  ```
+
+  After
+
+  ```json
+  "schematicCollections": ["@angular/material"]
+  ```
+
+- The `defaultProject` workspace option has been deprecated. The project to use will be determined from the current working directory.
+
+### @angular-devkit/core
+
+- - `ContentHasMutatedException`, `InvalidUpdateRecordException`, `UnimplementedException` and `MergeConflictException` symbol from `@angular-devkit/core` have been deprecated in favor of the symbol from `@angular-devkit/schematics`.
+  - `UnsupportedPlatformException` - A custom error exception should be created instead.

+
+# 13.0.0 (2021-11-03)
+
+## Breaking Changes
+
+### @angular/cli
+
+- We drop support for Node.js versions prior to `12.20`.
+
+### @schematics/angular
+
+- `classlist.js` and `web-animations-js` are removed from application polyfills and uninstalled from the package. These were only needed for compatibility with Internet Explorer, which is no longer needed now that Angular only supports evergreen browsers. See: https://angular.dev/reference/versions#browser-support.
+
+Add the following to the polyfills file for an app to re-add these packages:
+
+```typescript
+import 'classlist.js';
+import 'web-animations-js';
+```
+
+And then run:
+
+```sh
+npm install classlist.js web-animations-js --save
+```
+
+- We removed several deprecated `@schematics/angular` deprecated options.
+- `lintFix` have been removed from all schematics. `ng lint --fix` should be used instead.
+- `legacyBrowsers` have been removed from the `application` schematics since IE 11 is no longer supported.
+- `configuration` has been removed from the `web-worker` as it was unused.
+- `target` has been removed from the `service-worker` as it was unused.
+
+### @angular-devkit/build-angular
+
+- Support for `karma-coverage-instanbul-reporter` has been dropped in favor of the official karma coverage plugin `karma-coverage`.
+
+- Support for `node-sass` has been removed. `sass` will be used by default to compile SASS and SCSS files.
+
+- `NG_PERSISTENT_BUILD_CACHE` environment variable option no longer have effect. Configure `cli.cache` in the workspace configuration instead.
+
+```json
+{
+  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
+  "version": 1,
+  "cli": {
+    "cache": {
+      "enabled": true,
+      "path": ".custom-cache-path",
+      "environment": "all"
+    }
+  }
+  ...
+}
+```
+
+- Calling `BuilderContext.scheduleBuilder()` with a builder from `@angular-devkit/build-angular` now requires passing the `target` property in the 3rd argument, like in the following example:
+
+  ```typescript
+  context.scheduleBuilder('@angular-devkit/build-angular:ng-packagr', options, {
+    target: context.target,
+  });
+  ```
+
+- The automatic inclusion of Angular-required ES2015 polyfills to support ES5 browsers has been removed. Previously when targeting ES5 within the application's TypeScript configuration or listing an ES5 requiring browser in the browserslist file, Angular-required polyfills were included in the built application. However, with Angular no longer supporting IE11, there are now no browsers officially supported by Angular that would require these polyfills. As a result, the automatic inclusion of these ES2015 polyfills has been removed. Any polyfills manually added to an application's code are not affected by this change.
+
+- With this change a number of deprecated dev-server builder options which proxied to the browser builder have been removed. These options should be configured in the browser builder instead.
+
+The removed options are:
+
+- `aot`
+- `sourceMap`
+- `deployUrl`
+- `baseHref`
+- `vendorChunk`
+- `commonChunk`
+- `optimization`
+- `progress`
+
+- With this change we removed several deprecated builder options
+- `extractCss` has been removed from the browser builder. CSS is now always extracted.
+- `servePathDefaultWarning` and `hmrWarning` have been removed from the dev-server builder. These options had no effect.
+
+- Deprecated `@angular-devkit/build-angular:tslint` builder has been removed. Use https://github.com/angular-eslint/angular-eslint instead.
+
+- Differential loading support has been removed. With Angular no longer supporting IE11, there are now no browsers officially supported by Angular that require ES5 code. As a result, differential loading's functionality for creating and conditionally loading ES5 and ES2015+ variants of an application is no longer required.
+
+- TypeScript versions prior to 4.4 are no longer supported.
+
+- The dev-server now uses WebSockets to communicate changes to the browser during HMR and live-reloaded. If during your development you are using a proxy you will need to enable proxying of WebSockets.
+
+- We remove inlining of Google fonts in WOFF format since IE 11 is no longer supported. Other supported browsers use WOFF2.
+
+### @angular-devkit/build-webpack
+
+- Support for `webpack-dev-server` version 3 has been removed. For more information about the migration please see: https://github.com/webpack/webpack-dev-server/blob/master/migration-v4.md
+
+Note: this change only affects users depending on `@angular-devkit/build-webpack` directly.
+
+### @angular-devkit/core
+
+- With this change we drop support for the deprecated behaviour to transform `id` in schemas. Use `$id` instead.
+
+Note: this only effects schematics and builders authors.
+
+- The deprecated JSON parser has been removed from public API. [jsonc-parser](https://www.npmjs.com/package/jsonc-parser) should be used instead.
+
+### @angular-devkit/schematics
+
+- `isAction` has been removed without replacement as it was unused.
+
+- With this change we remove the following deprecated APIs
+- `TslintFixTask`
+- `TslintFixTaskOptions`
+
+**Note:** this only effects schematics developers.
+
+### @ngtools/webpack
+
+- Deprecated `inlineStyleMimeType` option has been removed from `AngularWebpackPluginOptions`. Use `inlineStyleFileExtension` instead.
+
+- Applications directly using the `webpack-cli` and not the Angular CLI to build must set the environment variable `DISABLE_V8_COMPILE_CACHE=1`. The `@ngtools/webpack` package now uses dynamic imports to provide support for the ESM `@angular/compiler-cli` package. The `v8-compile-cache` package used by the `webpack-cli` does not currently support dynamic import expressions and will cause builds to fail if the environment variable is not specified. Applications using the Angular CLI are not affected by this limitation.
+
+## Deprecations

+- `@angular-devkit/build-optimizer`
+
+It's functionality has been included in `@angular-devkit/build-angular` so this package is no longer needed by the CLI and we will stop publishing the package soon. It has been an experimental (never hit `1.0.0`) and internal (only used by Angular itself) package and should be not be used directly by others.
+
+### @angular-devkit/build-angular
+
+- `NG_BUILD_CACHE` environment variable option will be removed in the next major version. Configure `cli.cache` in the workspace configuration instead.

+</h3>
+A number of browser and server builder options have had their default values changed. The aim of these changes is to reduce the configuration complexity and support the new "production builds by default" initiative.
+
+**Browser builder**
+| Option | Previous default value | New default value |
+|----------------------------------------|---------------------------|-------------------|
+| optimization | false | true |
+| aot | false | true |
+| buildOptimizer | false | true |
+| sourceMap | true | false |
+| extractLicenses | false | true |
+| namedChunks | true | false |
+| vendorChunk | true | false |
+
+**Server builder**
+| Option | Previous default value | New default value |

+    @angular-devkit/core: update schema validator (<a href="https://github.com/angular/angular-cli/commit/08753138d336fb870a66face70f5624ba64b4c69">0875313</a>)
+</h3>
+support for JSON Schema draft-04 and draft-06 is removed. If you have schemas using the `id` keyword replace them with `$id`. For an interim period we will auto rename any top level `id` keyword to `$id`.
+
+**NB**: This change only effects schematics and builders authors.
+
+<h3>
+    @angular-devkit/build-angular: upgrade to Webpack 5 throughout the build system (<a href="https://github.com/angular/angular-cli/commit/d883ce5d7e39de774fe90e4ccdbc9a84a600b7e8">d883ce5</a>)
+</h3>
+Webpack 5 lazy loaded file name changes
+Webpack 5 generates similar but differently named files for lazy loaded JavaScript files in development configurations (when the `namedChunks` option is enabled).
+For the majority of users this change should have no effect on the application and/or build process. Production builds should also not be affected as the `namedChunks` option is disabled by default in production configurations.
+However, if a project's post-build process makes assumptions as to the file names then adjustments may need to be made to account for the new naming paradigm.
+Such post-build processes could include custom file transformations after the build, integration into service-side frameworks, or deployment procedures.
+Example development file name change: `lazy-lazy-module.js` --> `src_app_lazy_lazy_module_ts.js`
+
+Webpack 5 now includes web worker support. However, the structure of the URL within the `Worker` constructor must be in a specific format that differs from the current requirement.
+Web worker usage should be updated as shown below (where `./app.worker` should be replaced with the actual worker name):
+Before: `new Worker('./app.worker', ...)`
+After: `new Worker(new URL('./app.worker', import.meta.url), ...)`
+
+<h3>
+    @ngtools/webpack: remove Webpack plugin for deprecated ViewEngine compiler (<a href="https://github.com/angular/angular-cli/commit/160102ae57d780dded6c9002faf07b601a866d3d">160102a</a>)
+</h3>
+Removal of View Engine support from application builds
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the View Engine Webpack plugin has been removed.
+The Ivy-based Webpack plugin is the default used within the Angular CLI.
+If using a custom standalone Webpack configuration, the removed `AngularCompilerPlugin` should be replaced with the Ivy-based `AngularWebpackPlugin`.
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated i18n options from server and browser builder (<a href="https://github.com/angular/angular-cli/commit/5cf9a08dc7a1c84568d00df8f957d55b10ce0193">5cf9a08</a>)
+</h3>
+Removal of deprecated browser and server command options.
+- `i18nFile`,  use `locales` object in the project metadata instead.
+- `i18nFormat`, No longer needed as the format will be determined automatically.
+- `i18nLocale`, use `localize` option instead.
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated i18nLocale and i18nFormat options from i18n-extract (<a href="https://github.com/angular/angular-cli/commit/eca5a01f6e8d1c3ad874d74c58e6ffbddab6a031">eca5a01</a>)
+</h3>
+Removal of deprecated `extract-i18n` command options
+The deprecated `i18nLocale` option has been removed and the `i18n.sourceLocale` within a project's configuration should be used instead.
+The deprecated `i18nFormat` option has been removed and the `format` option should be used instead.
+
+<h3>
+    @angular-devkit/build-angular: remove usage of deprecated View Engine compiler (<a href="https://github.com/angular/angular-cli/commit/677913fc389f0ffa20e3e1928d7244427c07ef35">677913f</a>)
+</h3>
+Removal of View Engine support from application builds
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, Ivy-based compilation will always be used when building an application.
+The default behavior for applications is to use the Ivy compiler when building and no changes are required for these applications.
+For applications that have opted-out of Ivy, a warning will be shown and an Ivy-based build will be attempted. If the build fails,
+the application may need to be updated to become Ivy compatible.
+
+<h3>
+    @schematics/angular: remove `entryComponent` from `component` schematic (<a href="https://github.com/angular/angular-cli/commit/8582ddc35e153b8bc409d0505f29bc43e6cef455">8582ddc</a>)
+</h3>
+`entryComponent` option has been removed from the `component` schematic as this was intended to be used with the now no longer supported ViewEngine rendering engine.
+
+<h3>
+    @angular-devkit/build-angular: remove view engine app-shell generation (<a href="https://github.com/angular/angular-cli/commit/1c2aeeb46a23fd511c89f9c8800ac2a5ab0c2734">1c2aeeb</a>)

+App-shell builder now only supports generation using Ivy
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated View Engine support for i18n extraction (<a href="https://github.com/angular/angular-cli/commit/012700ace56d6d0e35d6798c5a19534ffa5a5a0e">012700a</a>)
+</h3>
+Removal of View Engine support from i18n extraction
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the `ng extract-i18n` command will now always use the Ivy compiler.
+The `--ivy` option has also been removed as Ivy-based extraction is always enabled.
+The default behavior for applications is to use the Ivy compiler for building/extraction and no changes are required for these applications.
+For applications that have opted-out of Ivy, a warning will be shown and Ivy-based extraction will be attempted. If the extraction fails,
+the application may need to be updated to become Ivy compatible.
+
+<h3>
+    @angular/cli: confirm ng add action before installation (<a href="https://github.com/angular/angular-cli/commit/985dc1a4c71693ad78c35f5d6e95397f9753239e">985dc1a</a>)
+</h3>
+The `ng add` command will now ask the user to confirm the package and version prior to installing and executing an uninstalled package.
+This new behavior allows a user to abort the action if the version selected is not appropriate or if a typo occurred on the command line and an incorrect package would be installed.
+A `--skip-confirmation` option has been added to skip the prompt and directly install and execute the package. This option is useful in CI and non-TTY scenarios such as automated scripts.
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated `lazyModules` option (<a href="https://github.com/angular/angular-cli/commit/8d669123236c49e7f6bee1a7171c002abe03df1a">8d66912</a>)
+</h3>
+Server and Browser builder `lazyModules` option has been removed without replacement.
+
+<h3>

+</h3>
+With this change we drop support for string based lazy loading `./lazy.module#LazyModule`  use dynamic imports instead.
+
+The following options which were used to support the above syntax were removed without replacement.
+
+- discoverLazyRoutes
+- additionalLazyModules

+support for JSON Schema draft-04 and draft-06 is removed. If you have schemas using the `id` keyword replace them with `$id`. For an interim period we will auto rename any top level `id` keyword to `$id`.

+</h3>
+Webpack 5 generates similar but differently named files for lazy loaded JavaScript files in development configurations (when the `namedChunks` option is enabled).
+For the majority of users this change should have no effect on the application and/or build process. Production builds should also not be affected as the `namedChunks` option is disabled by default in production configurations.
+However, if a project's post-build process makes assumptions as to the file names then adjustments may need to be made to account for the new naming paradigm.
+Such post-build processes could include custom file transformations after the build, integration into service-side frameworks, or deployment procedures.
+Example development file name change: `lazy-lazy-module.js` --> `src_app_lazy_lazy_module_ts.js`

+</h3>
+Webpack 5 now includes web worker support. However, the structure of the URL within the `Worker` constructor must be in a specific format that differs from the current requirement.
+Web worker usage should be updated as shown below (where `./app.worker` should be replaced with the actual worker name):
+
+Before:
+
+```
+new Worker('./app.worker', ...)
+```
+
+After:
+
+```
+new Worker(new URL('./app.worker', import.meta.url), ...)

+    @angular-devkit/build-angular: remove usage of deprecated View Engine compiler (<a href="https://github.com/angular/angular-cli/commit/677913fc389f0ffa20e3e1928d7244427c07ef35">677913f</a>)
+</h3>
+Removal of View Engine support from application builds
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, Ivy-based compilation will always be used when building an application.
+The default behavior for applications is to use the Ivy compiler when building and no changes are required for these applications.
+For applications that have opted-out of Ivy, a warning will be shown and an Ivy-based build will be attempted. If the build fails,
+the application may need to be updated to become Ivy compatible.
+
+<h3>
+    @schematics/angular: remove `entryComponent` from `component` schematic (<a href="https://github.com/angular/angular-cli/commit/8582ddc35e153b8bc409d0505f29bc43e6cef455">8582ddc</a>)
+</h3>
+`entryComponent` option has been removed from the `component` schematic as this was intended to be used with the now no longer supported ViewEngine rendering engine.
+
+<h3>
+    @angular-devkit/build-angular: remove view engine app-shell generation (<a href="https://github.com/angular/angular-cli/commit/1c2aeeb46a23fd511c89f9c8800ac2a5ab0c2734">1c2aeeb</a>)
+</h3>
+App-shell builder now only supports generation using Ivy
+
+<h3>
+    @angular-devkit/build-angular: remove deprecated View Engine support for i18n extraction (<a href="https://github.com/angular/angular-cli/commit/012700ace56d6d0e35d6798c5a19534ffa5a5a0e">012700a</a>)
+</h3>
+Removal of View Engine support from i18n extraction
+With the removal of the deprecated View Engine compiler in Angular version 12 for applications, the `ng extract-i18n` command will now always use the Ivy compiler.
+The `--ivy` option has also been removed as Ivy-based extraction is always enabled.
+The default behavior for applications is to use the Ivy compiler for building/extraction and no changes are required for these applications.
+For applications that have opted-out of Ivy, a warning will be shown and Ivy-based extraction will be attempted. If the extraction fails,
+the application may need to be updated to become Ivy compatible.

+    @angular/cli: confirm ng add action before installation (<a href="https://github.com/angular/angular-cli/commit/985dc1a4c71693ad78c35f5d6e95397f9753239e">985dc1a</a>)
+</h3>
+The `ng add` command will now ask the user to confirm the package and version prior to installing and executing an uninstalled package.
+This new behavior allows a user to abort the action if the version selected is not appropriate or if a typo occurred on the command line and an incorrect package would be installed.
+A `--skip-confirmation` option has been added to skip the prompt and directly install and execute the package. This option is useful in CI and non-TTY scenarios such as automated scripts.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering a safe and welcoming environment, we as
+the Angular team pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity, gender expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Use welcoming and inclusive language
+* Respect each other
+* Provide and gracefully accept constructive criticism
+* Show empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* The use of sexualized language or imagery
+* Unwelcome sexual attention or advances
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Angular team are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Angular team have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, and to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies to all Angular communication channels - online or in person,
+and it also applies when an individual is representing the project or its community in
+public spaces. Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the Angular team at conduct@angular.io. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The Angular team
+will maintain confidentiality with regard to the reporter of an incident.
+Enforcement may result in an indefinite ban from all official Angular communication
+channels, or other actions as deemed appropriate by the Angular team.
+
+Angular maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+### Appeal
+
+If you are banned you may contest the decision. To do so email conduct@angular.io with the subject line "Repeal Ban for {{your name here}}" and body with the responses to the following:
+
+* Why do you believe you did not violate the Code of Conduct?
+* Were other factors involved in this situation the leadership team may have been unaware of?
+* Why do you wish to be a part of the Angular community?
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org), version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

 ## <a name="public-api"></a> Updating the Public API
-Our Public API is protected with TS API Guardian. This is a tool that keeps track of public API surface of our packages.
-
-To test if your change effect the public API you need to run the API guardian on that particular package.
-
-For example in case `@angular-devkit/core` package was modified you need to run:
-
-```bash
-yarn bazel test //etc/api:angular_devkit_core_api
-```
+Our Public API surface is tracked using golden files.
 
-You can also test all packages by running:
+You check all golden files by running:
 ```bash
-yarn bazel test //etc/api ...
+pnpm public-api:check
 ```
 
 If you modified the public API, the test will fail. To update the golden files you need to run:
-
 ```bash
-yarn bazel run //etc/api:angular_devkit_core_api.accept
-```
-
-**Note**: In some cases we use aliased symbols to create namespaces.
-
-Example:
-```javascript
-import * as foo from './foo';
-
-export { foo };
+pnpm public-api:update
 ```
-There are currently not supported by the API guardian.
-To overcome this limitation we created `_golden-api.ts` in certain packages.
-
-When adding a new API, it might be the case that you need to add it to `_golden-api.ts`.

+## Development Setup
 
-----
 
-## The Goal of Angular CLI
+### Prerequisites
 
-The Angular CLI creates, manages, builds and test your Angular projects. It's built on top of the
-Angular DevKit.
+- Install [Node.js] which includes [Node Package Manager][npm]
 
-## The Goal of DevKit
+### Setting Up a Project
 
-DevKit's goal is to provide a large set of libraries that can be used to manage, develop, deploy and
-analyze your code.
+Install the Angular CLI globally:
 
-# Getting Started - Local Development
-
-## Installation
-
-To get started locally, follow these instructions:
-
-1. If you haven't done it already, [make a fork of this repo](https://github.com/angular/angular-cli/fork).
-1. Clone to your local computer using `git`.
-1. Make sure that you have Node 10.13 or later installed. See instructions [here](https://nodejs.org/en/download/).
-1. Make sure that you have `yarn` installed; see instructions [here](https://yarnpkg.com/lang/en/docs/install/).
-1. Run `yarn` (no arguments) from the root of your clone of this project to install dependencies.
-
-## Building and Installing the CLI
-
-To make a local build:
-
-```shell
-yarn build --local
+```
+npm install -g @angular/cli
 ```
 
-This generates a number of tarballs in the `dist/` directory. To actually use
-the locally built tools, switch to another repository reproducing the specific
-issue you want to fix (or just generate a local repo with `ng new`). Then
-install the locally built packages:
+Create workspace:
 
-```shell
-cd "${EXAMPLE_ANGULAR_PROJECT_REPO}"
-npm install -D ${CLI_REPO}/dist/*.tgz
+```
+ng new [PROJECT NAME]
 ```
 
-Builds of this example project will use tooling created from the previous local
-build and include any local changes. When using the CLI, it will automatically
-check for a local install and use that if present. This means you can just run:
+Run the application:
 
-```shell
-npm install -g @angular/cli
+```
+cd [PROJECT NAME]
+ng serve
 ```
 
-to get a global install of the latest CLI release. Then running any `ng` command
-in the example project will automatically find and use the local build of the
-CLI.
+Angular is cross-platform, fast, scalable, has incredible tooling, and is loved by millions.
 
-Note: If you are testing `ng update`, be aware that installing all the tarballs
-will also update the framework (`@angular/core`) to the latest version. In this
-case, simply install the CLI alone with
-`npm install -D ${CLI_REPO}/dist/_angular_cli.tgz`, that way the rest of the
-project remains to be upgraded with `ng update`.
+## Quickstart
 
-## Debugging
+[Get started in 5 minutes][quickstart].
 
-To debug an invocation of the CLI, [build and install the CLI for an example
-project](#building-and-installing-the-cli), then run the desired `ng` command
-as:
+## Ecosystem
 
-```shell
-node --inspect-brk node_modules/.bin/ng ...
-```
+<p>
+  <img src="http://github.com/docs/images/angular-ecosystem-logos.png" alt="angular ecosystem logos" width="500px" height="auto">
+</p>
+
+- [Angular Framework][adev]
+- [Angular Material][angularmaterial]
 
-This will trigger a breakpoint as the CLI starts up. You can connect to this
-using the supported mechanisms for your IDE, but the simplest option is to open
-Chrome to [chrome://inspect](chrome://inspect) and then click on the `inspect`
-link for the `node_modules/.bin/ng` Node target.
+## Changelog
 
-Unfortunately, the CLI dynamically `require()`'s other files mid-execution, so
-the debugger is not aware of all the source code files before hand. As a result,
-it is tough to put breakpoints on files before the CLI loads them. The easiest
-workaround is to use the `debugger;` statement to stop execution in the file you
-are interested in, and then you should be able to step around and set breakpoints
-as expected.
+[Learn about the latest improvements][changelog].
 
-## Testing
+## Upgrading
 
-There are three different test suites which can be run locally:
+Check out our [upgrade guide](https://update.angular.dev/) to find out the best way to upgrade your project.
 
-* Unit tests
-  * Run: `yarn test --full`
-  * Debug: `yarn debug:test --full`
-* Large tests
-  * Run: `yarn test-large --full`
-  * Debug: `yarn debug:test-large --full`
-* End to end tests
-  * Run: `node tests/legacy-cli/run_e2e.js`
-  * Run subset of tests: `node tests/legacy-cli/run_e2e.js tests/legacy-cli/e2e/tests/i18n/ivy-localize-*`
+## Contributing
 
-When running the debug commands, Node will stop and wait for a debugger to
-attach. You can attach your IDE to the debugger to stop on breakpoints and step through the code. Also see [IDE Specific Usage](#ide-specific-usage) for a
-simpler debug story.
+### Contributing Guidelines
 
-When debugging a specific test, change `describe()` or `it()` to `fdescribe()`
-and `fit()` to focus execution to just that one test. This will keep the output clean and speed up execution by not running irrelevant tests.
+Read through our [contributing guidelines][contributing] to learn about our submission process, coding rules and more.
 
-## IDE Specific Usage
+### Want to Help?
 
-Some additional tips for developing in specific IDEs.
+Want to report a bug, contribute some code, or improve documentation? Excellent! Read up on our guidelines for [contributing][contributing] and then check out one of our issues labeled as <kbd>[help wanted](https://github.com/angular/angular-cli/labels/help%20wanted)</kbd> or <kbd>[good first issue](https://github.com/angular/angular-cli/labels/good%20first%20issue)</kbd>.
 
-### Intellij IDEA / WebStorm
+### Code of Conduct
 
-To load the project in Intellij products, simply `Open` the repository folder.
-Do **not** `Import Project`, because that will overwrite the existing
-configuration.
+Help us keep Angular open and inclusive. Please read and follow our [Code of Conduct][codeofconduct].
 
-Once opened, the editor should automatically detect run configurations in the
-workspace. Use the drop down to choose which one to run and then click the `Run`
-button to start it. When executing a debug target, make sure to click the
-`Debug` icon to automatically attach the debugger (if you click `Run`, Node will
-wait forever for a debugger to attach).
+### Developer Guide
 
-![Intellij IDEA run configurations](docs/images/run-configurations.png)
+Read through our [developer guide][developer] to learn about how to build and test the Angular CLI locally.
 
-## Creating New Packages
 
-Adding a package to this repository means running two separate commands:
+## Community
 
-1. `schematics devkit:package PACKAGE_NAME`. This will update the `.monorepo` file, and create the
-  base files for the new package (package.json, src/index, etc).
-1. `devkit-admin templates`. This will update the README and all other template files that might
-  have changed when adding a new package.
+Join the conversation and help the community.
 
-For private packages, you will need to add a `"private": true` key to your package.json manually.
-This will require re-running the template admin script.

-# `/bin` Folder
-
-This folder includes binaries that are linked when globally linking this repository.
-
-Each file in this directory follows this pattern:
-
-1. JavaScript only.
-1. Requires `../lib/bootstrap-local.js` to bootstrap TypeScript and Node integration.
-1. Requires `../lib/packages` and use the package metadata to find the binary script for the 
-package the script is bootstrapping.
-1. Call out main, or simply require the file if it has no export.
-
-`devkit-admin` does not follow this pattern as it needs to setup logging and run some localized 
-logic.
-
-In order to add a new script, you should make sure it's in the root `package.json`, so people
-linking this repo get a reference to the script.

+# Building and Testing Angular CLI
+
+## Installation
+
+To get started locally, follow these instructions:
+
+1. If you haven't done it already, [make a fork of this repo](https://github.com/angular/angular-cli/fork).
+2. If you are on Windows, see [the extra steps needed for contributing on Windows](#windows)
+3. Clone to your local computer using `git`.
+4. Make sure that you have Node `v20.18.1` or higher installed. See instructions [here](https://nodejs.org/en/download/).
+5. Install `pnpm`.
+   - You can install pnpm by running `npm i -g pnpm@9`.
+   - See detailed instructions [here](https://pnpm.io/installation).
+6. Run `pnpm install` from the root of your clone of this project to install dependencies.
+
+## Building and Installing the CLI
+
+To make a local build:
+
+```shell
+pnpm build --local
+```
+
+This generates a number of tarballs in the `dist/` directory. To actually use
+the locally built tools, switch to another repository reproducing the specific
+issue you want to fix (or just generate a local repo with `ng new`). Then
+install the locally built packages:
+
+```shell
+cd "${EXAMPLE_ANGULAR_PROJECT_REPO}"
+npm install -D ${CLI_REPO}/dist/*.tgz
+```
+
+Builds of this example project will use tooling created from the previous local
+build and include any local changes. When using the CLI, it will automatically
+check for a local install and use that if present. This means you can just run:
+
+```shell
+npm install -g @angular/cli
+```
+
+to get a global install of the latest CLI release. Then running any `ng` command
+in the example project will automatically find and use the local build of the
+CLI.
+
+Note: If you are testing `ng update`, be aware that installing all the tarballs
+will also update the framework (`@angular/core`) to the latest version. In this
+case, simply install the CLI alone with
+`npm install -D ${CLI_REPO}/dist/_angular_cli.tgz`, that way the rest of the
+project remains to be upgraded with `ng update`.
+
+## Debugging
+
+To debug an invocation of the CLI, [build and install the CLI for an example
+project](#building-and-installing-the-cli), then run the desired `ng` command
+as:
+
+```shell
+node --inspect-brk node_modules/.bin/ng ...
+```
+
+This will trigger a breakpoint as the CLI starts up. You can connect to this
+using the supported mechanisms for your IDE, but the simplest option is to open
+Chrome to [chrome://inspect](chrome://inspect) and then click on the `inspect`
+link for the `node_modules/.bin/ng` Node target.
+
+Unfortunately, the CLI dynamically `require()`'s other files mid-execution, so
+the debugger is not aware of all the source code files before hand. As a result,
+it is tough to put breakpoints on files before the CLI loads them. The easiest
+workaround is to use the `debugger;` statement to stop execution in the file you
+are interested in, and then you should be able to step around and set breakpoints
+as expected.
+
+## Testing
+
+There are two different test suites which can be run locally:
+
+### Unit tests
+
+- Run all tests: `pnpm bazel test //packages/...`
+- Run a subset of the tests, use the full Bazel target example: `pnpm bazel test //packages/schematics/angular:angular_test`
+- For a complete list of test targets use the following Bazel query: `pnpm bazel query "tests(//packages/...)"`
+
+When debugging a specific test, change `describe()` or `it()` to `fdescribe()`
+and `fit()` to focus execution to just that one test. This will keep the output clean and speed up execution by not running irrelevant tests.
+
+You can find more info about debugging [tests with Bazel in the docs.](https://github.com/angular/angular-cli/blob/main/docs/process/bazel.md#debugging-jasmine_node_test)
+
+### End to end tests
+
+- For a complete list of test targets use the following Bazel query: `pnpm bazel query "tests(//tests/...)"`
+- Run a subset of the tests: `pnpm bazel test //tests/legacy-cli:e2e_node22 --config=e2e --test_filter="tests/i18n/ivy-localize-*"`
+- Use `bazel run` to debug failing tests debugging: `pnpm bazel run //tests/legacy-cli:e2e_node22 --config=e2e --test_arg="--glob=tests/basic/aot.ts"`
+- Provide additional `e2e_runner` options using `--test_arg`: `--test_arg="--package-manager=yarn"`
+
+When running the debug commands, Node will stop and wait for a debugger to attach.
+You can attach your IDE to the debugger to stop on breakpoints and step through the code. Also, see [IDE Specific Usage](#ide-specific-usage) for a
+simpler debug story.
+
+## IDE Specific Usage
+
+Some additional tips for developing in specific IDEs.
+
+### Intellij IDEA / WebStorm
+
+To load the project in Intellij products, simply `Open` the repository folder.
+Do **not** `Import Project`, because that will overwrite the existing
+configuration.
+
+Once opened, the editor should automatically detect run configurations in the
+workspace. Use the drop down to choose which one to run and then click the `Run`
+button to start it. When executing a debug target, make sure to click the
+`Debug` icon to automatically attach the debugger (if you click `Run`, Node will
+wait forever for a debugger to attach).
+
+![Intellij IDEA run configurations](images/run-configurations.png)
+
+### VS Code
+
+In order to debug some Angular CLI behaviour using Visual Studio Code, you can run `npm run build`, and then use a launch configuration like the following:
+
+```json
+{
+  "type": "node",
+  "request": "launch",
+  "name": "ng serve",
+  "cwd": "<path to an Angular project generated with Angular-CLI>",
+  "program": "${workspaceFolder}/dist/@angular/cli/bin/ng",
+  "args": [
+    "<ng command>",
+    ...other arguments
+  ],
+  "console": "integratedTerminal"
+}
+```
+
+Then you can add breakpoints in `dist/@angular` files.
+
+For more information about Node.js debugging in VS Code, see the related [VS Code Documentation](https://code.visualstudio.com/docs/nodejs/nodejs-debugging).
+
+## CPU Profiling
+
+In order to investigate performance issues, CPU profiling is often useful.
+
+### Creating a profile
+
+Node.js 16+ users can use the Node.js command line argument `--cpu-prof` to create a CPU profile.
+
+```bash
+node --cpu-prof node_modules/.bin/ng build
+```
+
+In addition to this one, another, more elaborated way to capture a CPU profile using the Chrome Devtools is detailed in https://github.com/angular/angular-cli/issues/8259#issue-269908550.
+
+#### Opening a profile
+
+You can use the Chrome Devtools to process it. To do so:
+
+1. open `chrome://inspect` in Chrome
+1. click on "Open dedicated DevTools for Node"
+1. go to the "profiler" tab
+1. click on the "Load" button and select the generated `.cpuprofile` file
+1. on the left panel, select the associated file
+
+## Creating New Packages
+
+Adding a package to this repository means running two separate commands:
+
+1. `schematics devkit:package PACKAGE_NAME`. This will update the `.monorepo` file, and create the
+   base files for the new package (package.json, src/index, etc).
+1. `devkit-admin templates`. This will update the README and all other template files that might
+   have changed when adding a new package.
+
+For private packages, you will need to add a `"private": true` key to your package.json manually.
+This will require re-running the template admin script.
+
+## Windows
+
+To contribute to Angular using a Windows machine, you need to use the [Windows Linux Subsystem](https://learn.microsoft.com/en-us/windows/wsl/about) (also known as WSL).
+Installing WSL on your machine requires a few extra steps, but we believe it's generally useful for developing on Windows:
+
+1.  Run `wsl --install` from Powershell (as administrator).
+2.  Restart your machine.
+3.  Enter the WSL environment by running: `wsl`.
+4.  Continue with the developer guide as if you were on a native Linux system.
+
+For a more detailed guide, refer to the official Microsoft documentation: [Installing WSL](https://learn.microsoft.com/en-us/windows/wsl/install).
+
+**Note:** Angular continues to support native Windows development via the `ng` CLI and rigorously tests on Windows for every code change. This recommendation specifically applies to contributing to the Angular codebase itself.

 Any change to analytics should most probably include a change to this document.
 
-# Pageview
-Each command creates a pageview with the path `/command/${commandName}/${subcommandName}`. IE.
-`ng generate component my-component --dryRun` would create a page view with the path
-`/command/generate/@schematics_angular/component`.
-
-We use page views to keep track of sessions more effectively, and to tag events to a page.

-Project names and target names will be removed. 
-The command `ng run some-project:lint:some-configuration` will create a page view with the path
-`/command/run`.

 ### Differential Loading
+
 Differential loading is a strategy that allows your web application to support multiple browsers, but only load the necessary code that the browser needs.
 When differential loading is enabled, the CLI generates two distinct variants of application bundles.
 
-* The first contains ES2015 syntax, takes advantage of built-in support in modern browsers, ships fewer polyfills, and results in a smaller total size.
-* The second contains code in the older ES5 syntax, along with all necessary polyfills for Angular to function. This results in a larger total size, but supports older browsers.
+- The first contains ES2015 syntax, takes advantage of built-in support in modern browsers, ships fewer polyfills, and results in a smaller total size.
+- The second contains code in the older ES5 syntax, along with all necessary polyfills for Angular to function. This results in a larger total size, but supports older browsers.
 
 This process as designed has the advantage that only one full compilation of the application in ES2015 syntax is required.
 This removes a large amount of otherwise unnecessary and duplicate processing such as module resolution and dead code elimination.
 It also guarantees that the application is ES5 compliant including third-party code.
 The two variants of application bundles are created by the following steps:
-1) A full build of the application is performed using an ES2015 output target.
-The application's global stylesheets, scripts, and assets are also processed during this step via the full build.  These elements are reused for both of application variants.
-2) A copy of the JavaScript output application files are transformed (commonly referred to as down-leveled) to ES5 compatible syntax.
-ES2015+ syntax elements such as classes are converted into functionally equivalent ES5 code structures.
-3) An additional ES5-only polyfills file is generated that contains the required Angular polyfills for ES5-only browsers.
-4) A single index HTML file is created that references both application variants and is designed to only load the appropriate files for each browser.

+4. A single index HTML file is created that references both application variants and is designed to only load the appropriate files for each browser.
 
 To support loading the file sets in the appropriate browsers, the HTML `script` element's `type` and `nomodule` attributes are leveraged.
 Browsers will only load a script with a known type.
 The ES2015 files are referenced using a type of `module` which is only supported on browsers that support ES2015+ code.
 Since browsers that do not support ES2015+ code also do not support the `module` script type, these scripts are ignored for browsers that cannot parse and execute the ES2015 code.
 Browsers that support the `module` script type also support the `nomodule` attribute.

-# Docker Deploy - Design
-
-## Abstract
-
-Add convenience for users to containerize and deploy their Angular application via Docker.
-
-Provide tasks for common Docker workflows:
-
-* Generate starter `Dockerfile` and `docker-compose.yml` files.
-* Build and Push an Angular app image to a Docker Registry.
-* Deploy and run an Angular app container in different Docker Machine environments.
-
-
-## Requirements
-
-1. Requires user to have Docker CLI tools installed.
-   (See also: ["Implementation Approaches"](#implementation-approaches))
-1. User is free to use the Angular CLI without Docker (and vice versa). By default, do not generate Docker files upon creation of a new project (`ng new`).
-1. Don't recreate the wheel. Docker CLI tools are very full featured on their own. Implement the common Docker use cases that make it convenient for Angular applications.
-1. Don't inhibit users from using the standalone Docker CLI tools for other use cases.
-1. Assumes 1:1 Dockerfile with the Angular project. Support for multiple services under the same project is outside the scope of this initial design.
-1. Generated starter Dockerfile will use an Nginx base image for the default server. The built ng app and Nginx configuration for HTML5 Fallback will be copied into the image.
-1. User is free to modify and customize all generated files directly without involvement by the Angular CLI.
-1. Image builds will support all Docker build options.
-1. Container deploys will support all Docker run options.
-1. Deploying to a Docker Machine can be local or remote.
-1. Deploys can be made to different environments (dev, stage, prod) on the same or different Docker Machines.
-1. Image pushes can be made to Docker Hub, AWS ECR, and other public/private registries.
-1. Adhere to [Docker security best practices](https://docs.docker.com/engine/security/).
-1. Use sensible defaults to make it easy for users to get started.
-1. Support `--dry-run` and `--verbose` flags.
-
-
-## Proposed CLI API
-
-### Overview
-
-Initialize the project for Docker builds and deploys:
-```
-$ ng docker init [--environment env]
-```
-
-Build and push a Docker image of the Angular app to the registry:
-```
-$ ng docker push [--registry url]
-```
-
-Deploy and run the Angular app on a Docker Machine:
-```
-$ ng docker deploy [--environment env]
-```
-
-### Command - Docker Init
-
-The command `ng docker init` generates starter `Dockerfile`, `.dockerignore`, and `docker-compose.yml` files for builds and and deploys.
-
-Most users will start with one local 'default' Docker Machine (Mac/Win), or a local native Docker environment on Linux, where they will perform builds and run containers for development testing. Without additional arguments, this command prepares the Angular project for working with that default environment.
-
-**Arguments:**
-
-* `--environment {env}` ; initialize for a particular environment (ie. dev, stage, prod). Defaults to `"default"`.
-* `--machine {machineName}` ; choose a particular Docker Machine for this environment. Defaults to the environment name.
-* `--service-name {serviceName}` ; the name for the webservice that serves the angular application. Defaults to `project.name`
-* `--service-port {servicePort}` ; the service port that should be mapped on the host. Defaults to `8000`.
-* `--use-image` ; initializes the environment for deploying with an image, rather than performing a build. By default, this is `false` and the `docker-compose.yml` file will be initialized for builds.
-* `--image-org {orgName}` ; the org name to use for image pushes. Defaults to `null`.
-* `--image-name {imageName}` ; the image name to use for image pushes. Also applies when `--use-image` is `true`. Defaults to `serviceName`.
-* `--image-registry {address}` ; the registry address to use for image pushes. Defaults to `registry.hub.docker.com`. Also applies when `--use-image` is `true`.
-
-**Example - Init default environment:**
-
-```bash
-$ ng docker:init --image-org my-username
-
-Generated 'Dockerfile'
-Generated '.dockerignore'
-Generated 'docker-compose.yml'
-
-Docker is ready!
-
-You can build and push a Docker image of your application to a docker registry using:
-  $ ng docker push
-
-Build and run your application using:
-  $ ng docker deploy
-```
-
-**Other requirements:**
-
-If the Docker CLI tools are not found, display an error with instructions on how to install Docker Toolbox. If no Docker Machines are found, display an error with instructions for creating a machine.
-
-The command should verify that the `machineName` is valid, and be able to distinguish whether it is a remote machine or a native local Docker environment (ie. Linux, Docker Native beta).
-
-A notice will be displayed for any files that already exist. No existing files will be overwritten or modified. Users are free to edit and maintain the generated files.
-
-If an `env` name is provided, other than "default", generate compose files with the env name appended, ie. `docker-compose-${env}.yml`.
-
-If `--use-image == false` and the selected machine for the environment is a Docker Swarm machine, warn the user. Docker Swarm clusters cannot use the `build:` option in compose, since the resulting built image will not be distributed to other nodes. Swarm requires using the `image:` option in compose, pushing the image to a registry beforehand so that the Swarm nodes have a place to pull the image from (see [Swarm Limitations](https://docs.docker.com/compose/swarm/#building-images)).
-
-Certain configuration values will be stored in the project's ngConfig `.angular-cli.json` for use with other docker commands (ie. deploy, logs, exec). See also: [Saved State](#saved-state) section.
-
-Provide instructions on what the user can do after initialization completes (push, deploy).
-
-Users who do not wish to push images to a registry should not be forced to.
-
-#### Example - `Dockerfile` blueprint
-
-```Dockerfile
-# You are free to change the contents of this file
-FROM nginx
-
-# Configure for angular fallback routes
-COPY nginx.conf /etc/nginx/nginx.conf
-
-# Copy built app to wwwroot
-COPY dist /usr/share/nginx/html
-```
-
-#### Example - `.dockerignore` blueprint
-
-```
-.git
-.gitignore
-.env*
-node_modules
-docker-compose*.yml
-```
-
-#### Example - `docker-compose.yml` blueprint
-
-For default case, when `--use-image == false`:
-
-```yaml
-version: "2"
-services:
-  ${serviceName}:
-    build: .
-    image: ${imageName}
-    ports:
-      - "${servicePort}:80"
-```
-
-When `--use-image == true`:
-
-```yaml
-version: "2"
-services:
-  ${serviceName}:
-    image: \${NG_APP_IMAGE}
-    ports:
-      - "${servicePort}:80"
-```
-
-The `\${NG_APP_IMAGE}` is a Compose variable, not an Angilar CLI var. It will be substituted during a `docker deploy` command with an environment variable of the desired tag. (See [Compose Variable Substitution](https://docs.docker.com/compose/compose-file/#variable-substitution) for more info)
-
-Separate `docker-compose-{environment}.yml` files are used to deploy to different [environments](https://docs.docker.com/compose/extends/#example-use-case), for use with the `ng docker deploy` command.
-
-
-### Command - Docker Push
-
-The command `ng docker push` builds a Docker image of the Angular app from the `Dockerfile`, and pushes the image with a new tag to a registry address.
-
-Example - Build and push (with auth):
-```bash
-$ ng docker push --tag 1.0.0 --tag-latest
-Building image...
-Tagging "1.0.0"...
-Tagging "latest"
-Docker image built! bc2043fdd1e8
-
-Pushing to registry...
-> Enter your registry credentials
-Username (username):
-Password:
-
-Push complete!
-my-username/my-ng-app:1.0.0
-my-username/my-ng-app:latest
-```
-
-#### Arguments
-
-* `--machine {machineName}` ; the Docker Machine to use for the build. Defaults to the "default" environment's `machineName`.
-* `--image-org {orgName}` ; the org name to use for image pushes. Defaults to `null`.
-* `--image-name {imageName}` ; the image name to use for image pushes. Defaults to `serviceName`.
-* `--image-registry {address}` ; the registry address to use for image pushes. Defaults to `registry.hub.docker.com`.
-* `--tag {tag}` ; the tag for the newly built image. Defaults to the current `package.json` "version" property value.
-* `--tag-latest` ; optionally and additionally apply the "latest" tag. Defaults to `false`.
-* `--no-cache` ; do not use cache when building the image. Defaults to `false`.
-* `--force-rm` ; always remove intermediate containers. Defaults to `false`.
-* `--pull` ; always attempt to pull a newer version of the image. Defaults to `false`.
-
-The `--no-cache`, `--force-rm`, and `--pull` are [compose build options](https://docs.docker.com/compose/reference/build/).
-
-Try an initial push. If an authentication failure occurs, attempt to login via `docker login`, or with `aws ecr get-login` (if the registry address matches `/\.dkr\.ecr\./`). Proxy the CLI input to the login commands. Avoid storing any authentication values in ngConfig.
-
-The `serviceName`, `registryAddress`, `orgName`, and `imageName` defaults will first be retrieved from ngConfig, which were saved during the initial `ng docker init` command. If any of these values do not exist, warn the user with instructions to add via `ng docker init` or `ng set name=value`.
-
-#### Internal Steps
-
-1. `docker-machine env {machineName}` (if remote)
-1. Rebuild app for production
-1. `docker-compose build {serviceName}`
-1. `docker tag {imageName} {registryAddress}:{orgName}/{imageName}:{imageTag}`
-1. `docker push {registryAddress}:{orgName}/{imageName}:{imageTag}`
-1. `tag-latest == true` ?
-   1. `docker tag {imageName} {registryAddress}:{orgName}/{imageName}:latest`
-   1. `docker push {registryAddress}:{orgName}/{imageName}:latest`
-
-
-### Command - Docker Deploy
-
-The command `ng docker deploy` will deploy an environment's compose configuration to a Docker Machine. It starts the containers in the background and leaves them running.
-
-Consider a command alias: `ng docker run`.
-
-Example - Default environment deploy:
-```bash
-$ ng docker deploy
-Building...
-Deploying to default environment...
-Deploy complete!
-```
-
-Example - Deploying to a named environment, without builds:
-```bash
-$ ng docker:deploy --environment stage
-$ ng docker:deploy --environment prod --tag 1.0.1
-```
-
-Example - Deploying a specific service from the compose file:
-```bash
-$ ng docker deploy --services my-ng-app
-```
-
-#### Options
-
-* `--environment {env}` ;
-* `--tag {tag}` ; The tag to use whe deploying to non-build Docker Machine environments; Defaults to `package.json` "version" property value.
-* `--services {svc1} {svc2} ... {svcN}` ;
-* `--no-cache` ; do not use cache when building the image. Defaults to `false`.
-* `--force-rm` ; always remove intermediate containers. Defaults to `false`.
-* `--pull` ; always attempt to pull a newer version of the image. Defaults to `false`.
-* `--force-recreate` ; recreate containers even if their configuration and image haven't changed. Defaults to `false`.
-* `--no-recreate` ; if containers already exist, don't recreate them. Defaults to `false`.
-
-The `--services` option allows for specific services to be deployed. By default, all services within the corresponding compose file will be deployed.
-
-The `--no-cache`, `--force-rm`, and `--pull` are [compose build options](https://docs.docker.com/compose/reference/build/).
-
-The `--force-recreate`, `--no-recreate` are [compose up options](https://docs.docker.com/compose/reference/up/).
-
-Successive deploys should only restart the updated services and not affect other existing running services.
-
-> If there are existing containers for a service, and the service’s configuration or image was changed after the container’s creation, docker-compose up picks up the changes by stopping and recreating the containers (preserving mounted volumes). To prevent Compose from picking up changes, use the --no-recreate flag.
-
-Use the `tag` value for the `${NG_APP_IMAGE_TAG}` environment variable substitution in the compose file.
-
-Use the `env` value to namespace the `--project-name` of the container set, for use with docker-compose when using different environment deploys on the same Docker Machine. (See also: [Compose overview](https://docs.docker.com/compose/reference/overview/))
-
-#### Internal Steps
-
-1. `docker-machine env {machineName}` (if remote)
-1. `--use-image == true` ?
-   1. `export NG_APP_IMAGE={registryAddress}:{orgName}/{imageName}:{tag}`
-   1. `docker-compose up -d [services]`
-1. `--use-image == false` ?
-   1. Rebuild app for production
-   1. `docker-compose build {serviceName}`
-   1. `docker-compose up -d [services]`
-
-
-## Saved State
-
-Example ngConfig model for saved docker command state (per project):
-```
-{
-  docker: {
-    orgName: 'myusername',
-    imageName: 'ngapp',
-    registryAddress: 'registry.hub.docker.com',
-    environments: {
-      default: {
-        machineName: 'default',
-        isImageDeploy: false,
-        serviceName: 'ngapp'
-      },
-      stage: {
-        machineName: 'stage',
-        isImageDeploy: true,
-        serviceName: 'ngapp'
-      }
-    }
-  }
-}
-```
-
-
-## Other Enhancements
-
-* Ability to list the configured deploy environments.
-* Autocomplete environment names for `ng docker deploy`.
-* New command wrappers for `docker-compose logs`, and `docker exec` commands.
-* Create an Angular development environment image with everything packaged inside. Users can run the container with local volume mounts, and toolset will watch/rebuild for local file changes. Only requires Docker to be installed to get started with Angular development. There are some Node.js complexities to solve when adding new package.json dependencies, and many users report issues with file watchers and docker volume mounts.
-* Deployment support to other container scheduling systems: Kubernetes, Marathon/Mesos, AWS ECS and Beanstalk, Azure Service Fabric, etc.
-

-## Appendix
-
-### Implementation Approaches
-
-Two internal implementation approaches to consider when interfacing with Docker from Node.js:
-
-1. Docker Remote API via Node.js modules
-1. Docker CLI tools via `child_process.exec`
-
-#### Docker Remote API
-
-<https://docs.docker.com/engine/reference/api/docker_remote_api/>
-
-> The API tends to be REST. However, for some complex commands, like attach or pull, the HTTP connection is hijacked to transport stdout, stdin and stderr.
-
-The API has been going through a high rate of change and has some awkward inconsistencies:
-
-> Build Image: reply is chunked into JSON objects like {"stream":"data"} and {"error":"problem"} instead of multiplexing stdout and stderr like the rest of the API.
-
-Example Image Build with `dockerode` module:
-
-```js
-var Docker = require('dockerode');
-var tar = require('tar-fs');
-
-var docker = new Docker({
-    host: options.dockerHostIp,
-    port: options.dockerPort || 2375,
-    ca: fs.readFileSync(`${options.dockerCertPath}/ca.pem`),
-    cert: fs.readFileSync(`${options.dockerCertPath}/cert.pem`),
-    key: fs.readFileSync(`${options.dockerCertPath}/key.pem`)
-});
-var buildImagePromise = Promise.denodeify(docker.buildImage);
-var tarStream = tar.pack(project.root);
-
-buildImagePromise(tarStream, {
-    t: options.imageName
-}).then((output) => {
-    var imageHash = output.match(/Successfully built\s+([a-f0-9]+)/m)[1];
-    ui.writeLine(chalk.green(`Docker image built! ${imageHash}`));
-});
-```
-
-Tradeoffs with this approach:
-
-* Does not require Docker CLI tools to be installed.
-* Requires cert files for access to remote Docker Machines.
-* Programmatic interface.
-* Requires more configuration on the part of Angular CLI.
-* Configuration imposes a learning curve on existing Docker users.
-* No Docker-Compose API support. Multi-container management features would need to be duplicated.
-* Maintenance effort to keep API updated.
-* Dependent upon 3rd-party Docker module support, or creating our own.
-
-#### Execute Docker CLI Commands
-
-This method wraps the following Docker CLI tools with `exec()` calls, formatting the command arguments and parsing their output:
-
-* `docker-machine` : Used to initialize the `docker` client context for communication with a specific Docker Machine host, and for gathering host information (IP address).
-* `docker` : The primary Docker client CLI. Good for pushing images to a registry.
-* `docker-compose` : Manages multi-container deployments on a Docker Machine using a YAML format for defining container options. Can also be used to build images.
-
-Example image build with `docker-machine` and `docker-compose` CLI commands:
-
-```js
-var execPromise = Promise.denodeify(require('child_process').exec);
-
-function getDockerEnv(machineName) {
-    return execPromise(`docker-machine env ${machineName}`)
-        .then((stdout) => {
-            let dockerEnv = {};
-            stdout.split(/\r?\n/)
-                .forEach((line) => {
-                    let m = line.match(/^export\s+(.+?)="(.*?)"$/);
-                    if (m) dockerEnv[m[1]] = m[2];
-                });
-            return dockerEnv;
-        });
-}
-
-function buildImage() {
-    return getDockerEnv(options.buildMachineName)
-        .then((dockerEnv) => {
-            let execOptions = {
-                cwd: project.root,
-                env: dockerEnv
-            };
-            return execPromise(`docker-compose build ${options.dockerServiceName}`, execOptions);
-        })
-        .then((stdout) => {
-            var imageHash = stdout.match(/Successfully built\s+([a-f0-9]+)/m)[1];
-            ui.writeLine(chalk.green(`Docker image built! ${imageHash}`));
-            return imageHash
-        });
-}
-```
-
-Tradeoffs with this approach:
-
-* Requires user to manually install Docker CLI tools
-* Must build interface around CLI commands, formatting the command arguments and parsing the output.
-* Can leverage Docker-Compose and its configuration format for multi-container deploys.
-* Configuration of build and deploy options is simplified in Angular CLI.
-* User has the flexibility of switching between `ng` commands and Docker CLI tools without having to maintain duplicate configuration.
-* Lower risk of Docker compatibility issues. User has control over their Docker version.

-
-#### Summary
-
-The "2. Docker CLI tools via `child_process.exec`" method is recommended based on the following:
-
-* The requirement of having the Docker CLI tools installed is not generally a problem, and they would likely already be installed by the majority of users using these features.
-* Maintenance to Angular CLI would likely be easier using the Docker CLI, having less configuration, documentation, and updates than the Remote API method.
-* Multi-container deploys is a common use-case. Utilizing the Docker Compose features, format, and documentation is a big win.
-* Since this project is a CLI itself, using the Docker CLI tools isn't too far a leap.
-* Users who do not use these features are not forced to install Docker CLI. Conversely, the Remote API method might incur a small penalty of installing unused NPM modules (ie. `dockerode`).

-* What is my firebase database URL?
-* Where is my client code?
-* How can I use a different lazy-loading boundary prefix (or none at all)?

-# ng build
-
-## Overview
-`ng build` compiles the application into an output directory
-
-### Creating a build
-
-```bash
-ng build
-```
-
-The build artifacts will be stored in the `dist/` directory.
-
-All commands that build or serve your project, `ng build/serve/e2e`, will delete the output
-directory (`dist/` by default).
-This can be disabled via the `--no-delete-output-path` (or `--delete-output-path=false`) flag.
-
-### Build Targets and Environment Files
-
-`ng build` can specify both a build target (`--target=production` or `--target=development`) and an
-environment file to be used with that build (`--environment=dev` or `--environment=prod`).
-By default, the development build target and environment are used.
-
-The mapping used to determine which environment file is used can be found in `.angular-cli.json`:
-
-```json
-"environmentSource": "environments/environment.ts",
-"environments": {
-  "dev": "environments/environment.ts",
-  "prod": "environments/environment.prod.ts"
-}
-```
-
-These options also apply to the serve command. If you do not pass a value for `environment`,
-it will default to `dev` for `development` and `prod` for `production`.
-
-```bash
-# these are equivalent
-ng build --target=production --environment=prod
-ng build --prod --env=prod
-ng build --prod
-# and so are these
-ng build --target=development --environment=dev
-ng build --dev --e=dev
-ng build --dev
-ng build
-```
-
-You can also add your own env files other than `dev` and `prod` by doing the following:
-- create a `src/environments/environment.NAME.ts`
-- add `{ "NAME": 'src/environments/environment.NAME.ts' }` to the `apps[0].environments` object in `.angular-cli.json`
-- use them via the `--env=NAME` flag on the build/serve commands.
-
-### Base tag handling in index.html
-
-When building you can modify base tag (`<base href="http://github.com/">`) in your index.html with `--base-href your-url` option.
-
-```bash
-# Sets base tag href to /myUrl/ in your index.html
-ng build --base-href /myUrl/
-ng build --bh /myUrl/
-```
-
-### Bundling & Tree-Shaking
-
-All builds make use of bundling and limited tree-shaking, while `--prod` builds also run limited
-dead code elimination via UglifyJS.
-
-### `--dev` vs `--prod` builds
-
-Both `--dev`/`--target=development` and `--prod`/`--target=production` are 'meta' flags, that set other flags.
-If you do not specify either you will get the `--dev` defaults.
-
-Flag                | `--dev` | `--prod`
----                 | ---     | ---
-`--aot`             | `false` | `true`
-`--environment`     | `dev`   | `prod`
-`--output-hashing`  | `media` | `all`
-`--sourcemaps`      | `true`  | `false`
-`--extract-css`     | `false` | `true`
-`--named-chunks`    | `true`  | `false`
-`--build-optimizer` | `false` | `true` with AOT and Angular 5
-
-`--prod` also sets the following non-flaggable settings:
-- Adds service worker if configured in `.angular-cli.json`.
-- Replaces `process.env.NODE_ENV` in modules with the `production` value (this is needed for some libraries, like react).
-- Runs UglifyJS on the code.
-
-### `--build-optimizer` and `--vendor-chunk`
-
-When using Build Optimizer the vendor chunk will be disabled by default.
-You can override this with `--vendor-chunk=true`.
-
-Total bundle sizes with Build Optimizer are smaller if there is no separate vendor chunk because
-having vendor code in the same chunk as app code makes it possible for Uglify to remove more unused
-code.
-
-### CSS resources
-
-Resources in CSS, such as images and fonts, will be copied over automatically as part of a build.
-If a resource is less than 10kb it will also be inlined.
-
-You'll see these resources be outputted and fingerprinted at the root of `dist/`.
-
-### Service Worker
-
-There is experimental service worker support for production builds available in the CLI.
-To enable it, run the following commands:
-```
-npm install @angular/service-worker --save
-ng set apps.0.serviceWorker=true
-```
-
-On `--prod` builds a service worker manifest will be created and loaded automatically.
-Remember to disable the service worker while developing to avoid stale code.
-
-Note: service worker support is experimental and subject to change.
-
-### ES2015 support
-
-To build in ES2015 mode, edit `./tsconfig.json` to use `"target": "es2015"` (instead of `es5`).
-
-This will cause application TypeScript and Uglify be output as ES2015, and third party libraries
-to be loaded through the `es2015` entry in `package.json` if available.
-
-Be aware that JIT does not support ES2015 and so you should build/serve your app with `--aot`.
-See https://github.com/angular/angular-cli/issues/7797 for details.

-configuration and using the `--force` flag.

-# Angular CLI
-
-NOTE: this documentation is for Angular CLI 1.x. For Angular CLI 6 go [here](home) instead.
-
-### Overview
-The Angular CLI is a tool to initialize, develop, scaffold  and maintain [Angular](https://angular.io) applications
-
-### Getting Started
-To install the Angular CLI:
-```
-npm install -g @angular/cli
-```
-
-Generating and serving an Angular project via a development server
-[Create](1-x/new) and [run](1-x/serve) a new project:
-```
-ng new my-project
-cd my-project
-ng serve
-```
-Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
-
-### Bundling
-
-All builds make use of bundling, and using the `--prod` flag in  `ng build --prod`
-or `ng serve --prod` will also make use of uglifying and tree-shaking functionality.
-
-### Running unit tests
-
-```bash
-ng test
-```
-
-Tests will execute after a build is executed via [Karma](http://karma-runner.github.io/0.13/index.html), and it will automatically watch your files for changes. You can run tests a single time via `--watch=false` or `--single-run`.
-
-### Running end-to-end tests
-
-```bash
-ng e2e
-```
-
-Before running the tests make sure you are serving the app via `ng serve`.
-End-to-end tests are run via [Protractor](http://www.protractortest.org/).
-
-### Additional Commands
-* [ng new](1-x/new)
-* [ng serve](1-x/serve)
-* [ng generate](1-x/generate)
-* [ng lint](1-x/lint)
-* [ng test](1-x/test)
-* [ng e2e](1-x/e2e)
-* [ng build](1-x/build)
-* [ng get/ng set](1-x/config)
-* [ng doc](1-x/doc)
-* [ng eject](1-x/eject)
-* [ng xi18n](1-x/xi18n)
-* [ng update](1-x/update)
-
-## Angular CLI Config Schema
-* [Config Schema](1-x/angular-cli)
-
-### Additional Information
-There are several [stories](1-x/stories) which will walk you through setting up
-additional aspects of Angular applications.

-# Angular CLI migration guide
-
-In this migration guide we'll be looking at some of the major changes to CLI projects in the
-last two months.
-
-Most of these changes were not breaking changes and your project should work fine without them.
-
-But if you've been waiting for the perfect time to update, this is it!
-Along with major rebuild speed increases, we've been busy adding a lot of features.
-
-Documentation has also completely moved to [the wiki](https://github.com/angular/angular-cli/wiki).
-The new [Stories](https://github.com/angular/angular-cli/wiki/stories) section covers common usage
-scenarios, so be sure to have a look!
-
-Below are the changes between a project generated two months ago, with `1.0.0-beta.24` and
-a `1.0.0` project.
-If you kept your project up to date you might have a lot of these already.
-
-You can find more details about changes between versions in [the releases tab on GitHub](https://github.com/angular/angular-cli/releases).
-
-If you prefer, you can also generate a new project in a separate folder using
- `ng new upgrade-project --skip-install` and compare the differences.
-
-## @angular/cli
-
-Angular CLI can now be found on NPM under `@angular/cli` instead of `angular-cli`, and upgrading is a simple 3 step process:
-
-1. Uninstall old version
-2. Update node/npm if necessary
-3. Install new version
-
-### 1. Uninstall old version
-
-If you're using Angular CLI `beta.28` or less, you need to uninstall the `angular-cli` packages:
-```bash
-npm uninstall -g angular-cli          # Remove global package
-npm uninstall --save-dev angular-cli  # Remove from package.json
-```
-
-Otherwise, uninstall the  `@angular/cli` packages:
-```bash
-npm uninstall -g @angular/cli         # Remove global package
-npm uninstall --save-dev @angular/cli # Remove from package.json
-```
-
-Also purge the cache and local packages:
-```
-rm -rf node_modules dist # Use rmdir on Windows
-npm cache clean
-```
-
-At this point, you should not have Angular CLI on your system anymore. If invoking Angular CLI at the commandline reveals that it still exists on your system, you will have to manually remove it. See _Manually removing residual Angular CLI_.
-
-### 2. Update node/npm if necessary
-
-Angular CLI now has a minimum requirement of Node 6.9.0 or higher, together with NPM 3 or higher.
-
-If your Node or NPM versions do not meet these requirements, please refer to [the documentation](https://docs.npmjs.com/getting-started/installing-node) on how to upgrade. 
-
-### 3. Install the new version
-
-To update Angular CLI to a new version, you must update both the global package and your project's local package:
-
-```bash
-npm install -g @angular/cli@latest          # Global package
-npm install --save-dev @angular/cli@latest  # Local package
-npm install                                 # Restore removed dependencies
-```
-
-### Manually removing residual Angular CLI
-
-If you accidentally updated NPM before removing the old Angular CLI, you may find that uninstalling the package using `npm uninstall` is proving fruitless. This _could_ be because the global install (and uninstall) path changed between versions of npm from `/usr/local/lib` to `/usr/lib`, and hence, no longer searches through the old directory. In this case you'll have to remove it manually:
-
-`rm -rf /usr/local/lib/node_modules/@angular/cli`
-
-If the old Angular CLI package _still_ persists, you'll need to research how to remove it before proceeding with the upgrade.
-
-## .angular-cli.json
-
-`angular-cli.json` is now `.angular-cli.json`, but we still accept the old config file name.
-
-A few new properties have changed in it:
-
-### Schema
-
-Add the `$schema` property above project for handy IDE support on your config file:
-
-```
-"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
-```
-
-### Polyfills
-
-There is now a dedicated entry for polyfills ([#3812](https://github.com/angular/angular-cli/pull/3812))
-inside `apps[0].polyfills`, between `main` and `test`:
-
-```
-"main": "main.ts",
-"polyfills": "polyfills.ts",
-"test": "test.ts",
-```
-
-Add it and remove `import './polyfills.ts';` from `src/main.ts` and `src/test.ts`.
-
-We also added a lot of descriptive comments to the existing `src/polyfills.ts` file, explaining
-which polyfills are needed for what browsers.
-Be sure to check it out in a new project!
-
-### Environments
-
-A new `environmentSource` entry ([#4705](https://github.com/angular/angular-cli/pull/4705))
-replaces the previous source entry inside environments.
-
-To migrate angular-cli.json follow the example below:
-
-Before:
-```
-"environments": {
-  "source": "environments/environment.ts",
-  "dev": "environments/environment.ts",
-  "prod": "environments/environment.prod.ts"
-}
-```
-
-After:
-
-```
-"environmentSource": "environments/environment.ts",
-"environments": {
-  "dev": "environments/environment.ts",
-  "prod": "environments/environment.prod.ts"
-}
-```
-
-### Linting
-
-The CLI now uses the TSLint API ([#4248](https://github.com/angular/angular-cli/pull/4248))
-to lint several TS projects at once.
-
-There is a new `lint` entry in `.angular-cli.json` between `e2e` and `test` where all linting
-targets are listed:
-
-```
-"e2e": {
-  "protractor": {
-    "config": "./protractor.conf.js"
-  }
-},
-"lint": [
-  {
-    "project": "src/tsconfig.app.json"
-  },
-  {
-    "project": "src/tsconfig.spec.json"
-  },
-  {
-    "project": "e2e/tsconfig.e2e.json"
-  }
-],
-"test": {
-  "karma": {
-    "config": "./karma.conf.js"
-  }
-},
-```
-
-### Generator defaults
-
-Now you can list generator defaults per generator ([#4389](https://github.com/angular/angular-cli/pull/4389))
-in `defaults`.
-
-Instead of:
-```
-"defaults": {
-  "styleExt": "css",
-  "prefixInterfaces": false,
-  "inline": {
-    "style": false,
-    "template": false
-  },
-  "spec": {
-    "class": false,
-    "component": true,
-    "directive": true,
-    "module": false,
-    "pipe": true,
-    "service": true
-  }
-}
-```
-
-You can instead list the flags as they appear on [the generator command](https://github.com/angular/angular-cli/wiki/generate-component):
-```
-"defaults": {
-  "styleExt": "css",
-  "component": {
-    "inlineTemplate": false,
-    "spec": true
-  }
-}
-```
-
-## One tsconfig per app
-
-CLI projects now use one tsconfig per app ([#4924](https://github.com/angular/angular-cli/pull/4924)).
-
-- `src/tsconfig.app.json`: configuration for the Angular app.
-```
-{
-  "compilerOptions": {
-    "sourceMap": true,
-    "declaration": false,
-    "moduleResolution": "node",
-    "emitDecoratorMetadata": true,
-    "experimentalDecorators": true,
-    "target": "es5",
-    "lib": [
-      "es2017",
-      "dom"
-    ],
-    "outDir": "../out-tsc/app",
-    "module": "es2015",
-    "baseUrl": "",
-    "types": []
-  },
-  "exclude": [
-    "test.ts",
-    "**/*.spec.ts"
-  ]
-}
-```
-- `src/tsconfig.spec.json`: configuration for the unit tests.
-```
-{
-  "compilerOptions": {
-    "sourceMap": true,
-    "declaration": false,
-    "moduleResolution": "node",
-    "emitDecoratorMetadata": true,
-    "experimentalDecorators": true,
-    "lib": [
-      "es2017",
-      "dom"
-    ],
-    "outDir": "../out-tsc/spec",
-    "module": "commonjs",
-    "target": "es5",
-    "baseUrl": "",
-    "types": [
-      "jasmine",
-      "node"
-    ]
-  },
-  "files": [
-    "test.ts"
-  ],
-  "include": [
-    "**/*.spec.ts",
-    "**/*.d.ts"
-  ]
-}
-
-```
-- `e2e/tsconfig.e2e.json`: configuration for the e2e tests.
-```
-{
-  "compilerOptions": {
-    "sourceMap": true,
-    "declaration": false,
-    "moduleResolution": "node",
-    "emitDecoratorMetadata": true,
-    "experimentalDecorators": true,
-    "lib": [
-      "es2017"
-    ],
-    "outDir": "../out-tsc/e2e",
-    "module": "commonjs",
-    "target": "es5",
-    "types":[
-      "jasmine",
-      "node"
-    ]
-  }
-}
-
-```
-
-There is an additional root-level `tsconfig.json` that is used for IDE integration.
-```
-{
-  "compileOnSave": false,
-  "compilerOptions": {
-    "outDir": "./dist/out-tsc",
-    "baseUrl": "src",
-    "sourceMap": true,
-    "declaration": false,
-    "moduleResolution": "node",
-    "emitDecoratorMetadata": true,
-    "experimentalDecorators": true,
-    "target": "es5",
-    "typeRoots": [
-      "node_modules/@types"
-    ],
-    "lib": [
-      "es2017",
-      "dom"
-    ]
-  }
-}
-```
-
-You can delete `e2e/tsconfig.json` and `src/tsconfig.json` after adding these.
-
-Also update `.angular-cli.json` to use them inside `apps[0]`:
-
-```
-"tsconfig": "tsconfig.app.json",
-"testTsconfig": "tsconfig.spec.json",
-```
-
-Then update `protractor.conf.js` to use the e2e config as well:
-```
-beforeLaunch: function() {
-  require('ts-node').register({
-    project: 'e2e/tsconfig.e2e.json'
-  });
-},
-```
-
-These configs have an `types` array where you should add any package you install via `@types/*`.
-This array helps keep typings isolated to the apps that really need them and avoid problems with
-duplicate typings.
-
-For instance, the unit test `tsconfig` has `jasmine` and `node`, which correspond to
-`@types/jasmine` and `@types/node`.
-Add any typings you've installed to the appropriate `tsconfig` as well.
-
-## typings.d.ts
-
-There's a new `src/typings.d.ts` file that serves two purposes:
-- provides a centralized place for users to add their own custom typings
-- makes it easy to use components that use `module.id`, present in the documentation and in snippets
-
-```
-/* SystemJS module definition */
-declare var module: NodeModule;
-interface NodeModule {
-  id: string;
-}
-```
-
-## package.json
-
-We've updated a lot of packages over the last months in order to keep projects up to date.
-
-Additions or removals are found in bold below.
-
-Packages in `dependencies`:
-- `@angular/*` packages now have a `^4.0.0` minimum

-
-See the [karma](1-x/#karma.conf.js) and [protractor](1-x/#protractor.conf.js) sections below for more
-information on changed packages.
-
-The [Linting rules](1-x/#Linting rules) section contains a list of rules that changed due to updates.
-
-We also updated the scripts section to make it more simple:
-
-```
-"scripts": {
-  "ng": "ng",
-  "start": "ng serve",
-  "build": "ng build",
-  "test": "ng test",
-  "lint": "ng lint",
-  "e2e": "ng e2e"
-},
-```
-
-## karma.conf.js
-
-Karma configuration suffered some changes to improve the code-coverage functionality,
-use the new `@angular/cli` package, and the new HTML reporter.
-
-In the `frameworks` array update the CLI package to `@angular/cli`.
-
-In the `plugins` array:
-- add `require('karma-jasmine-html-reporter')` and `require('karma-coverage-istanbul-reporter')`
-- remove `require('karma-remap-istanbul')`
-- update the CLI plugin to `require('@angular/cli/plugins/karma')`
-
-Add a new `client` option just above `patterns`:
-```
-client:{
-  clearContext: false // leave Jasmine Spec Runner output visible in browser
-},
-files: [
-```
-
-Change the preprocessor to use the new CLI package:
-```
-preprocessors: {
-  './src/test.ts': ['@angular/cli']
-},
-```
-
-Replace `remapIstanbulReporter` with `coverageIstanbulReporter`:
-```
-coverageIstanbulReporter: {
-  reports: [ 'html', 'lcovonly' ],
-  fixWebpackSourcePaths: true
-},
-```
-
-Remove the config entry from `angularCli`:
-```
-angularCli: {
-  environment: 'dev'
-},
-```
-
-Update the reporters to use `coverage-istanbul` instead of `karma-remap-istanbul`, and
-add `kjhtml` (short for karma-jasmine-html-reporter):
-```
-reporters: config.angularCli && config.angularCli.codeCoverage
-          ? ['progress', 'coverage-istanbul']
-          : ['progress', 'kjhtml'],
-```
-
-## protractor.conf.js
-
-Protractor was updated to the new 5.x major version, but you shouldn't need to change much
-to take advantage of all its new features.
-
-Replace the spec reporter import from:
-```
-var SpecReporter = require('jasmine-spec-reporter');
-```
-to
-```
-const { SpecReporter } = require('jasmine-spec-reporter');
-```
-
-Remove `useAllAngular2AppRoots: true`.
-
-Update `beforeLaunch` as described in [One tsconfig per app](1-x/#one-tsconfig-per-app):
-```
-beforeLaunch: function() {
-  require('ts-node').register({
-    project: 'e2e/tsconfig.e2e.json'
-  });
-},
-```
-
-Update `onPrepare`:
-```
-onPrepare: function() {
-  jasmine.getEnv().addReporter(new SpecReporter({ spec: { displayStacktrace: true } }));
-}
-```
-
-## Linting rules
-
-The updated versions of `tslint` and `codelyzer` contain a few rule changes that you should
-apply to your `tslint.json`:
-
-Add these new rules:
-```
-"callable-types": true,
-"import-blacklist": [true, "rxjs"],
-"import-spacing": true,
-"interface-over-type-literal": true,
-"no-empty-interface": true,
-"no-string-throw": true,
-"prefer-const": true,
-"typeof-compare": true,
-"unified-signatures": true,
-```
-
-Update `no-inferrable-types` to `"no-inferrable-types": [true, "ignore-params"]`.

-# Application Environments
-
-## Configuring available environments
-
-`.angular-cli.json` contains an **environments** section.  By default, this looks like:
-
-``` json
-"environments": {
-    "dev": "environments/environment.ts",
-    "prod": "environments/environment.prod.ts"
-}
-```
-
-You can add additional environments as required.  To add a **staging** environment, your configuration would look like:
-
-``` json
-"environments": {
-    "dev": "environments/environment.ts",
-    "staging": "environments/environment.staging.ts",
-    "prod": "environments/environment.prod.ts"
-}
-```
-
-## Adding environment-specific files
-
-The environment-specific files are set out as shown below:
-
-```
-└── src
-    └── environments
-        ├── environment.prod.ts
-        └── environment.ts
-```
-
-If you wanted to add another environment for **staging**, your file structure would become:
-
-```
-└── src
-    └── environments
-        ├── environment.prod.ts
-        ├── environment.staging.ts
-        └── environment.ts
-```
-
-## Amending environment-specific files
-
-`environment.ts` contains the default settings.  If you take a look at this file, it should look like:
-
-``` TypeScript
-export const environment = {
-  production: false
-};
-```
-
-If you compare this to `environment.prod.ts`, which looks like:
-
-``` TypeScript
-export const environment = {
-  production: true
-};
-```
-
-You can add further variables, either as additional properties on the `environment` object, or as separate objects, for example:
-
-``` TypeScript
-export const environment = {
-  production: false,
-  apiUrl: 'http://my-api-url/'
-};
-```
-
-## Using environment-specific variables in your application
-
-Given the following application structure:
-
-```
-└── src
-    └── app
-        ├── app.component.html
-        └── app.component.ts
-    └── environments
-        ├── environment.prod.ts
-        ├── environment.staging.ts
-        └── environment.ts
-```
-
-Using environment variables inside of `app.component.ts` might look something like this:
-
-``` TypeScript
-import { Component } from '@angular/core';
-import { environment } from './../environments/environment';
-
-@Component({
-  selector: 'app-root',
-  templateUrl: './app.component.html',
-  styleUrls: ['./app.component.css']
-})
-export class AppComponent {
-  constructor() {
-    console.log(environment.production); // Logs false for default environment
-  }
-  title = 'app works!';
-}
-```
-
-## Environment-specific builds
-
-Running:
-
-```
-ng build
-```
-
-Will use the defaults found in `environment.ts`
-
-Running:
-
-```
-ng build --env=staging
-```
-
-Will use the values from `environment.staging.ts`

-# Project assets
-
-You use the `assets` array in `.angular-cli.json` to list files or folders you want to copy as-is
-when building your project.
-
-By default, the `src/assets/` folder and `src/favicon.ico` are copied over.
-
-```json
-"assets": [
-  "assets",
-  "favicon.ico"
-]
-```
-
-You can also further configure assets to be copied by using objects as configuration.
-
-The array below does the same as the default one:
-
-```json
-"assets": [
-  { "glob": "**/*", "input": "./assets/", "output": "./assets/" },
-  { "glob": "favicon.ico", "input": "./", "output": "./" },
-]
-```
-
-`glob` is the a [node-glob](https://github.com/isaacs/node-glob) using `input` as base directory.
-`input` is relative to the project root (`src/` default), while `output` is
- relative to `outDir` (`dist` default).
-
- You can use this extended configuration to copy assets from outside your project.
- For instance, you can copy assets from a node package:
-
- ```json
-"assets": [
-  { "glob": "**/*", "input": "../node_modules/some-package/images", "output": "./some-package/" },
-]
-```
-
-The contents of `node_modules/some-package/images/` will be available in `dist/some-package/`.
-
-## Writing assets outside of `dist/`
-
-Because of the security implications, the CLI will always refuse to read or write files outside of
-the project itself (scoped by `.angular-cli.json`). It is however possible to write assets outside
-the `dist/` build output folder during build.
-
-Because writing files in your project isn't an expected effect of `ng build`, it is disabled by 
-default on every assets. In order to allow this behaviour, you need to set `allowOutsideOutDir` 
-to `true` on your asset definition, like so:
-
-```json
-"assets": [
-  {
-    "glob": "**/*",
-    "input": "./assets/",
-    "output": "../not-dist/some/folder/",
-    "allowOutsideOutDir": true
-  },
-]
-```
-
-This needs to be set for every assets you want to write outside of your build output directory.

-# Change target browsers for Autoprefixer
-
-Currently, the CLI uses [Autoprefixer](https://github.com/postcss/autoprefixer) to ensure compatibility
-with different browser and browser versions. You may find it necessary to target specific browsers
-or exclude certain browser versions from your build.
-
-Internally, Autoprefixer relies on a library called [Browserslist](https://github.com/browserslist/browserslist)
-to figure out which browsers to support with prefixing.
-
-There are a few ways to tell Autoprefixer what browsers to target:
-
-### Add a browserslist property to the `package.json` file
-```
-"browserslist": [
-  "> 1%",
-  "last 2 versions"
-]
-```
-
-### Add a new file to the project directory called `.browserslistrc`
-```
-### Supported Browsers
-
-> 1%
-last 2 versions
-```
-
-Autoprefixer will look for the configuration file/property to use when it prefixes your css.
-Check out the [browserslist repo](https://github.com/browserslist/browserslist) for more examples of how to target
-specific browsers and versions.
-
-_Side note:_
-Those who are seeking to produce a [progressive web app](https://developers.google.com/web/progressive-web-apps/) and are using [Lighthouse](https://developers.google.com/web/tools/lighthouse/) to grade the project will
-need to add the following browserslist config to their package.json file to eliminate the [old flexbox](https://developers.google.com/web/tools/lighthouse/audits/old-flexbox) prefixes:
-
-`package.json` config:
-```
-"browserslist": [
-  "last 2 versions",
-  "not ie <= 10",
-  "not ie_mob <= 10"

-# Code Coverage
-
-With the Angular CLI we can run unit tests as well as create code coverage reports. Code coverage reports allow us to see any parts of our code base that may not be properly tested by our unit tests.
-
-To generate a coverage report run the following command in the root of your project
-
-```bash
-ng test --watch=false --code-coverage
-```
-
-Once the tests complete a new `/coverage` folder will appear in the project. In your Finder or Windows Explorer open the `index.html` file. You should see a report with your source code and code coverage values. 
-
-Using the code coverage percentages we can estimate how much of our code is tested. It is up to your team to determine how much code should be unit tested. 
-
-## Code Coverage Enforcement
-
-If your team decides on a set minimum amount to be unit tested you can enforce this minimum with the Angular CLI. For example our team would like the code base to have a minimum of 80% code coverage. To enable this open the `karma.conf.js` and add the following in the `coverageIstanbulReporter:` key
-
-```javascript
-coverageIstanbulReporter: {
-  reports: [ 'html', 'lcovonly' ],
-  fixWebpackSourcePaths: true,
-  thresholds: {
-    statements: 80,
-    lines: 80,
-    branches: 80,
-    functions: 80
-  }
-}
-``` 
-
-The `thresholds` property will enforce a minimum of 80% code coverage when the unit tests are run in the project.

-# Configure Hot Module Replacement
-
-Hot Module Replacement (HMR) is a WebPack feature to update code in a running app without rebuilding it.
-This results in faster updates and less full page-reloads.
-
-You can read more about HMR by visiting [this page](https://webpack.js.org/guides/hot-module-replacement/).
-
-In order to get HMR working with Angular CLI we first need to add a new environment and enable it.
-
-Next we need to update the bootstrap process of our app to enable the
-[@angularclass/hmr](https://github.com/gdi2290/angular-hmr) module.
-
-### Add environment for HMR
-
-Create a file called `src/environments/environment.hmr.ts` with the following contents:
-
-```typescript
-
-export const environment = {
- production: false,
- hmr: true
-};
-```
-
-Update `src/environments/environment.prod.ts` and add the `hmr: false` flag to the environment:
-
-```typescript
-export const environment = {
- production: true,
- hmr: false
-};
-```
-
-Update `src/environments/environment.ts` and add the `hmr: false` flag to the environment:
-
-```typescript
-export const environment = {
- production: false,
- hmr: false
-};
-```
-
-
-Update `.angular-cli.json` by adding the new environment the existing environments object:
-
-```json
-"environmentSource": "environments/environment.ts",
-"environments": {
-  "dev": "environments/environment.ts",
-  "hmr": "environments/environment.hmr.ts",
-  "prod": "environments/environment.prod.ts"
-},
-```
-
-Run `ng serve` with the flag `--hmr -e=hmr` to enable hmr and select the new environment:
-
-```bash
-ng serve --hmr -e=hmr
-```
-
-Create a shortcut for this by updating  `package.json` and adding an entry to the script object:
-
-```json
-"scripts": {
-  ...
-  "hmr": "ng serve --hmr -e=hmr"
-}
-```
-
-
-### Add dependency for @angularclass/hmr and configure app
-
-In order to get HMR working we need to install the dependency and configure our app to use it.
-
-
-Install the `@angularclass/hmr` module as a dev-dependency
-
-```bash
-$ npm install --save-dev @angularclass/hmr
-```
-
-
-Create a file called `src/hmr.ts` with the following content:
-
-```typescript
-import { NgModuleRef, ApplicationRef } from '@angular/core';
-import { createNewHosts } from '@angularclass/hmr';
-
-export const hmrBootstrap = (module: any, bootstrap: () => Promise<NgModuleRef<any>>) => {
-  let ngModule: NgModuleRef<any>;
-  module.hot.accept();
-  bootstrap().then(mod => ngModule = mod);
-  module.hot.dispose(() => {
-    const appRef: ApplicationRef = ngModule.injector.get(ApplicationRef);
-    const elements = appRef.components.map(c => c.location.nativeElement);
-    const makeVisible = createNewHosts(elements);
-    ngModule.destroy();
-    makeVisible();
-  });
-};
-```
-
-
-Update `src/main.ts` to use the file we just created:
-
-```typescript
-import { enableProdMode } from '@angular/core';
-import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
-
-import { AppModule } from './app/app.module';
-import { environment } from './environments/environment';
-
-import { hmrBootstrap } from './hmr';
-
-if (environment.production) {
-  enableProdMode();
-}
-
-const bootstrap = () => platformBrowserDynamic().bootstrapModule(AppModule);
-
-if (environment.hmr) {
-  if (module[ 'hot' ]) {
-    hmrBootstrap(module, bootstrap);
-  } else {
-    console.error('HMR is not enabled for webpack-dev-server!');
-    console.log('Are you using the --hmr flag for ng serve?');
-  }
-} else {
-  bootstrap();
-}
-```
-
-
-### Starting the development environment with HMR enabled
-
-Now that everything is set up we can run the new configuration:
-
-```bash
-$ npm run hmr
-```
-
-When starting the server Webpack will tell you that it’s enabled:
-
-
-    NOTICE Hot Module Replacement (HMR) is enabled for the dev server.
-
-
-Now if you make changes to one of your components they changes should be visible automatically without a complete browser refresh.

-# Continuous Integration
-
-One of the best ways to keep your project bug free is through a test suite, but it's easy to forget
-to run tests all the time.
-
-That's where Continuous Integration (CI) servers come in.
-You can set up your project repository so that your tests run on every commit and pull request.
-
-There are paid CI services like [Circle CI](https://circleci.com/) and
-[Travis CI](https://travis-ci.com/), and you can also host your own for free using
-[Jenkins](https://jenkins.io/) and others.
-
-Even though Circle CI and Travis CI are paid services, they are provided free for open source
-projects.
-You can create a public project on GitHub and add these services without paying.
-
-We're going to see how to update your test configuration to run in CI environments, and how to
-set up Circle CI and Travis CI.
-
-
-## Update test configuration
-
-Even though `ng test` and `ng e2e` already run on your environment, they need to be adjusted to
-run in CI environments.
-
-When using Chrome in CI environments it has to be started without sandboxing.
-We can achieve that by editing our test configs.
-
-In `karma.conf.js`, add a custom launcher called `ChromeNoSandbox` below `browsers`:
-
-```
-browsers: ['Chrome'],
-customLaunchers: {
-  ChromeNoSandbox: {
-    base: 'Chrome',
-    flags: ['--no-sandbox']
-  }
-},
-```
-
-Create a new file in the root of your project called `protractor-ci.conf.js`, that extends
-the original `protractor.conf.js`:
-
-```
-const config = require('./protractor.conf').config;
-
-config.capabilities = {
-  browserName: 'chrome',
-  chromeOptions: {
-    args: ['--no-sandbox']
-  }
-};
-
-exports.config = config;
-```
-
-Now you can run the following commands to use the `--no-sandbox` flag:
-
-```
-ng test --single-run --no-progress --browser=ChromeNoSandbox
-ng e2e --no-progress --config=protractor-ci.conf.js
-```
-
-For CI environments it's also a good idea to disable progress reporting (via `--no-progress`)
-to avoid spamming the server log with progress messages.
-
-
-## Using Circle CI
-
-Create a folder called `.circleci` at the project root, and inside of it create a file called
-`config.yml`:
-
-```yaml
-version: 2
-jobs:
-  build:
-    working_directory: ~/my-project
-    docker:
-      - image: circleci/node:8-browsers
-    steps:
-      - checkout
-      - restore_cache:
-          key: my-project-{{ .Branch }}-{{ checksum "package.json" }}
-      - run: npm install
-      - save_cache:
-          key: my-project-{{ .Branch }}-{{ checksum "package.json" }}
-          paths:
-            - "node_modules"
-      - run: xvfb-run -a npm run test -- --single-run --no-progress --browser=ChromeNoSandbox
-      - run: xvfb-run -a npm run e2e -- --no-progress --config=protractor-ci.conf.js
-
-```
-
-We're doing a few things here:
-  -
-  - `node_modules` is cached.
-  - [npm run](https://docs.npmjs.com/cli/run-script) is used to run `ng` because `@angular/cli` is
-  not installed globally. The double dash (`--`) is needed to pass arguments into the npm script.
-  - `xvfb-run` is used to run `npm run` to run a command using a virtual screen, which is needed by
-  Chrome.
-
-Commit your changes and push them to your repository.
-
-Next you'll need to [sign up for Circle CI](https://circleci.com/docs/2.0/first-steps/) and
-[add your project](https://circleci.com/add-projects).
-Your project should start building.
-
-Be sure to check out the [Circle CI docs](https://circleci.com/docs/2.0/) if you want to know more.
-
-
-## Using Travis CI
-
-Create a file called `.travis.yml` at the project root:
-
-```yaml
-dist: trusty
-sudo: false
-
-language: node_js
-node_js:
-  - "8"
-  
-addons:
-  apt:
-    sources:
-      - google-chrome
-    packages:
-      - google-chrome-stable
-
-cache:
-  directories:
-     - ./node_modules
-
-install:
-  - npm install
-
-script:
-  # Use Chromium instead of Chrome.
-  - export CHROME_BIN=chromium-browser
-  - xvfb-run -a npm run test -- --single-run --no-progress --browser=ChromeNoSandbox
-  - xvfb-run -a npm run e2e -- --no-progress --config=protractor-ci.conf.js
-
-```
-
-Although the syntax is different, we're mostly doing the same steps as were done in the
-Circle CI config.
-The only difference is that Travis doesn't come with Chrome, so we use Chromium instead.
-
-Commit your changes and push them to your repository.
-
-Next you'll need to [sign up for Travis CI](https://travis-ci.org/auth) and
-[add your project](https://travis-ci.org/profile).
-You'll need to push a new commit to trigger a build.
-
-Be sure to check out the [Travis CI docs](https://docs.travis-ci.com/) if you want to know more.

-# CSS Preprocessor integration
-
-Angular CLI supports all major CSS preprocessors:
-- sass/scss ([http://sass-lang.com/](http://sass-lang.com/))
-- less ([http://lesscss.org/](http://lesscss.org/))
-- stylus ([http://stylus-lang.com/](http://stylus-lang.com/))
-
-To use these preprocessors simply add the file to your component's `styleUrls`:
-
-```javascript
-@Component({
-  selector: 'app-root',
-  templateUrl: './app.component.html',
-  styleUrls: ['./app.component.scss']
-})
-export class AppComponent {
-  title = 'app works!';
-}
-```
-
-When generating a new project you can also define which extension you want for
-style files:
-
-```bash
-ng new sassy-project --style=sass
-```
-
-Or set the default style on an existing project:
-
-```bash
-ng set defaults.styleExt scss
-```
-
-Style strings added to the `@Component.styles` array _must be written in CSS_ because the CLI cannot apply a pre-processor to inline styles.

-# Serve from Disk
-
-The CLI supports running a live browser reload experience to users by running `ng serve`. This will compile the application upon file saves and reload the browser with the newly compiled application. This is done by hosting the application in memory and serving it via [webpack-dev-server](https://webpack.js.org/guides/development/#webpack-dev-server).
-
-If you wish to get a similar experience with the application output to disk please use the steps below. This practice will allow you to ensure that serving the contents of your `dist` dir will be closer to how your application will behave when it is deployed.
-
-## Environment Setup
-### Install a web server
-You will not be using webpack-dev-server, so you will need to install a web server for the browser to request the application. There are many to choose from but a good one to try is [lite-server](https://github.com/johnpapa/lite-server) as it will auto-reload your browser when new files are output.
-
-## Usage
-You will need two terminals to get the live-reload experience. The first will run the build in a watch mode to compile the application to the `dist` folder. The second will run the web server against the `dist` folder. The combination of these two processes will mimic the same behavior of ng serve.
-
-### 1st terminal - Start the build
-```bash
-ng build --watch
-```
-
-### 2nd terminal - Start the web server
-```bash
-lite-server --baseDir="dist"
-```
-When using `lite-server` the default browser will open to the appropriate URL.

-# Deploy to GitHub Pages
-
-A simple way to deploy your Angular app is to use
-[GitHub Pages](https://help.github.com/articles/what-is-github-pages/).
-
-The first step is to [create a GitHub account](https://github.com/join), and then
-[create a repository](https://help.github.com/articles/create-a-repo/) for your project.
-Make a note of the user name and project name in GitHub.
-
-Then all you need to do is run `ng build --prod --output-path docs --base-href PROJECT_NAME`, where
-`PROJECT_NAME` is the name of your project in GitHub.
-Make a copy of `docs/index.html` and name it `docs/404.html`.
-
-Commit your changes and push. On the GitHub project page, configure it to
-[publish from the docs folder](https://help.github.com/articles/configuring-a-publishing-source-for-github-pages/#publishing-your-github-pages-site-from-a-docs-folder-on-your-master-branch).
-
-And that's all you need to do! Now you can see your page at
-`https://USER_NAME.github.io/PROJECT_NAME/`.
-
-You can also use [angular-cli-ghpages](https://github.com/angular-schule/angular-cli-ghpages), a full
-featured package that does this all this for you and has extra functionality.

-# Global Library Installation
-
-Some javascript libraries need to be added to the global scope, and loaded as if
-they were in a script tag. We can do this using the `apps[0].scripts` and
-`apps[0].styles` properties of `.angular-cli.json`.
-
-As an example, to use [Bootstrap 4](https://getbootstrap.com/docs/4.0/getting-started/introduction/) this is
-what you need to do:
-
-First install Bootstrap from `npm`:
-
-```bash
-npm install jquery --save
-npm install popper.js --save
-npm install bootstrap@next --save
-```
-
-Then add the needed script files to `apps[0].scripts`:
-
-```json
-"scripts": [
-  "../node_modules/jquery/dist/jquery.slim.js",
-  "../node_modules/popper.js/dist/umd/popper.js",
-  "../node_modules/bootstrap/dist/js/bootstrap.js"
-],
-```
-
-Finally add the Bootstrap CSS to the `apps[0].styles` array:
-```json
-"styles": [
-  "../node_modules/bootstrap/dist/css/bootstrap.css",
-  "styles.css"
-],
-```
-
-Restart `ng serve` if you're running it, and Bootstrap 4 should be working on
-your app.

-# Global scripts
-
-You can add Javascript files to the global scope via the `apps[0].scripts`
-property in `.angular-cli.json`.
-These will be loaded exactly as if you had added them in a `<script>` tag inside `index.html`.
-
-This is especially useful for legacy libraries or analytic snippets.
-
-```json
-"scripts": [
-  "global-script.js",
-],
-```
-
-You can also rename the output and lazy load it by using the object format:
-
-```json
-"scripts": [
-  "global-script.js",
-  { "input": "lazy-script.js", "lazy": true },
-  { "input": "pre-rename-script.js", "output": "renamed-script" },
-],
-```
-
-## Using global libraries inside your app
-
-Once you import a library via the scripts array, you should **not** import it via a import statement
-in your TypeScript code (e.g. `import * as $ from 'jquery';`).
-If you do that, you'll end up with two different copies of the library: one imported as a
-global library, and one imported as a module.
-
-This is especially bad for libraries with plugins, like JQuery, because each copy will have
-different plugins.
-
-Instead, download typings for your library (`npm install @types/jquery`) and follow
-the [3rd Party Library Installation](https://github.com/angular/angular-cli/wiki/stories-third-party-lib) steps,
-this will give you access to the global variables exposed by that library.
-
-If the global library you need to use does not have global typings, you can also declare them
-manually in `src/typings.d.ts` as `any`:
-
-```
-declare var libraryName: any;
-```
-
-When working with scripts that extend other libraries, for instance with JQuery plugins
-(e.g, `$('.test').myPlugin();`), since the installed `@types/jquery` may not include `myPlugin`,
-you would need to add an interface like the one below in `src/typings.d.ts`.
-
-```
-interface JQuery {
-  myPlugin(options?: any): any;
-}
-```
-
-Otherwise you may see `[TS][Error] Property 'myPlugin' does not exist on type 'JQuery'.` in your IDE.

-# Global styles
-
-The `styles.css` file allows users to add global styles and supports
-[CSS imports](https://developer.mozilla.org/en/docs/Web/CSS/@import).
-
-If the project is created with the `--style=sass` option, this will be a `.sass`
-file instead, and the same applies to `scss/less/styl`.

-],
-```
-
-In Sass and Stylus you can also make use of the `includePaths` functionality for both component and
-global styles, which allows you to add extra base paths that will be checked for imports.
-
-To add paths, use the `stylePreprocessorOptions` entry in angular-cli.json `app` object:
-
-```
-"stylePreprocessorOptions": {
-  "includePaths": [
-    "style-paths"
-  ]
-},
-```
-
-Files in that folder, e.g. `src/style-paths/_variables.scss`, can be imported from anywhere in your
-project without the need for a relative path:
-
-```
-// src/app/app.component.scss
-// A relative path works
-@import 'http://github.com/style-paths/variables';
-// But now this works as well
-@import 'http://github.com/variables';

-# Include AngularFire
-
-[Firebase](https://firebase.google.com/) is a mobile and web application platform with tools and infrastructure designed
-to help developers build high-quality apps. [AngularFire2](https://github.com/angular/angularfire2) is the official
-Angular library to use Firebase in your apps.
-
-#### Create new project
-
-Create a new project and navigate into the project.
-
-```bash
-$ ng new my-app
-$ cd my-app
-```
-
-#### Install dependencies
-
-In the new project you need to install the required dependencies.
-
-```bash
-$ npm install --save angularfire2 firebase
-```
-
-#### Get Firebase configuration details
-
-In order to connect AngularFire to Firebase you need to get the configuration details.
-
-Firebase offers an easy way to get this, by showing a JavaScript object that you can copy and paste.
-
-- Log in to the [Firebase](https://firebase.google.com) console.
-- Create New Project or open an existing one.
-- Click `Add Firebase to your web app`.
-- From the modal window that pops up you copy the `config` object.
-
-```javascript
-  var config = {
-    apiKey: "your-api-key",
-    authDomain: "your-auth-domain",
-    databaseURL: "your-database-url",
-    storageBucket: "your-storage-bucket",
-    messagingSenderId: "your-message-sender-id"
-  };
-```
-
-#### Configure the Environment
-
-These configuration details need to be stored in our app, one way to do this using the `environment`. This allows you to
-use different credentials in development and production.
-
-Open `src/environments/environment.ts` and add a key `firebase` to the exported constant:
-
-```typescript
-export const environment = {
-  production: false,
-  firebase: {
-    apiKey: 'your-api-key',
-    authDomain: 'your-auth-domain',
-    databaseURL: 'your-database-url',
-    storageBucket: 'your-storage-bucket',
-  }
-};
-```
-
-To define the keys for production you need to update `src/environments/environment.prod.ts`.
-
-#### Import and load FirebaseModule
-
-The final step is to import `AngularFireModule` and initialize it using the parameters from the `environment`.
-
-Open `src/app/app.module.ts` and add the following lines on the top of the file, with the other imports:
-
-```typescript
-import { AngularFireModule } from 'angularfire2';
-import { environment } from '../environments/environment';
-```
-
-To initialize AngularFire add the following line to the `imports` array inside the `NgModule`:
-
-```typescript
-@NgModule({
-  // declarations
-  imports: [
-    // BrowserModule, etc
-    AngularFireModule.initializeApp(environment.firebase),
-  ]
-  // providers
-  // bootstrap
-})
-```
-
-#### Congratulations, you can now use Firebase in your Angular app!

-# Include [Bootstrap](http://getbootstrap.com/)
-
-[Bootstrap](http://getbootstrap.com/) is a popular CSS framework which can be used within an Angular project.
-This guide will walk you through adding bootstrap to your Angular CLI project and configuring it to use bootstrap.
-
-## Using CSS
-
-### Getting Started
-
-Create a new project and navigate into the project
-
-```
-ng new my-app
-cd my-app
-```
-
-### Installing Bootstrap
-
-With the new project created and ready you will next need to install bootstrap to your project as a dependency.
-Using the `--save` option the dependency will be saved in package.json
-
-```sh
-# version 3.x
-npm install bootstrap --save
-
-# version 4.x
-npm install bootstrap@next --save
-```
-
-### Configuring Project
-
-Now that the project is set up it must be configured to include the bootstrap CSS.
-
-- Open the file `.angular-cli.json` from the root of your project.
-- Under the property `apps` the first item in that array is the default application.
-- There is a property `styles` which allows external global styles to be applied to your application.
-- Specify the path to `bootstrap.min.css`
-
-  It should look like the following when you are done:
-  ```json
-  "styles": [
-    "../node_modules/bootstrap/dist/css/bootstrap.min.css",
-    "styles.css"
-  ],
-  ```
-
-**Note:** When you make changes to `.angular-cli.json` you will need to re-start `ng serve` to pick up configuration changes.
-
-### Testing Project
-
-Open `app.component.html` and add the following markup:
-
-```html
-<button class="btn btn-primary">Test Button</button>
-```
-
-With the application configured, run `ng serve` to run your application in develop mode.
-In your browser navigate to the application `localhost:4200`.
-Verify the bootstrap styled button appears.
-
-## Using SASS
-
-### Getting Started
-
-Create a new project and navigate into the project
-
-```
-ng new my-app --style=scss
-cd my-app
-```
-
-### Installing Bootstrap
-
-```sh
-# version 3.x
-npm install bootstrap-sass --save
-
-# version 4.x
-npm install bootstrap@next --save
-```
-
-### Configuring Project
-
-Create an empty file `_variables.scss` in `src/`.
-
-If you are using `bootstrap-sass`, add the following to `_variables.scss`:
-
-```sass
-$icon-font-path: '../node_modules/bootstrap-sass/assets/fonts/bootstrap/';
-```
-
-In `styles.scss` add the following:
-
-```sass
-// version 3
-@import 'http://github.com/variables';
-@import 'http://github.com/node_modules/bootstrap-sass/assets/stylesheets/_bootstrap';
-
-// version 4
-@import 'http://github.com/variables';
-@import 'http://github.com/node_modules/bootstrap/scss/bootstrap';
-```
-
-### Testing Project
-
-Open `app.component.html` and add the following markup:
-
-```html
-<button class="btn btn-primary">Test Button</button>
-```
-
-With the application configured, run `ng serve` to run your application in develop mode.
-In your browser navigate to the application `localhost:4200`.
-Verify the bootstrap styled button appears.
-To ensure your variables are used open `_variables.scss` and add the following:
-
-```sass
-// version 3
-$brand-primary: red;
-
-// version 4
-$primary: red;
-```
-
-Return the browser to see the font color changed.

-# Internationalization (i18n)
-
-If you are working on internationalization, the CLI can help you with the following steps:
-- extraction
-- serve
-- build
-
-The first thing that you have to do is to setup your application to use i18n.
-To do that you can follow [the cookbook on angular.io](https://angular.io/guide/i18n).
-
-### Extraction
-When your app is ready, you can extract the strings to translate from your templates with the
-`ng xi18n` command.
-
-By default it will create a file named `messages.xlf` in your `src` folder.
-You can use [parameters from the xi18n command](1-x/./xi18n) to change the format,
-the name, the location and the source locale of the extracted file.
-
-For example to create a file in the `src/locale` folder you would use:
-```sh
-ng xi18n --output-path src/locale
-```
-
-### Serve
-Now that you have generated a messages bundle source file, you can translate it.
-Let's say that your file containing the french translations is named `messages.fr.xlf`
-and is located in the `src/locale` folder.
-If you want to use it when you serve your application you can use the 4 following commands:
-- `--i18n-file` Localization file to use for i18n.
-- `--i18n-format` Format of the localization file specified with --i18n-file.
-- `--locale` Locale to use for i18n.
-- `--missing-translation` Defines the strategy to use for missing i18n translations.
-
-In our case we can load the french translations with the following command:
-```sh
-ng serve --aot --locale fr --i18n-format xlf --i18n-file src/locale/messages.fr.xlf --missing-translation error
-```
-
-Our application is exactly the same but the `LOCALE_ID` has been provided with "fr",
-`TRANSLATIONS_FORMAT` with "xlf" and `TRANSLATIONS` with the content of `messages.fr.xlf`.
-All the strings flagged for i18n have been replaced with their french translations.
-
-Note: this only works for AOT, if you want to use i18n in JIT you will have to update
-your bootstrap file yourself.
-
-### Build
-To build your application with a specific locale you can use the exact same commands
-that you used for `serve`:
-```sh
-ng build --aot --locale fr --i18n-format xlf --i18n-file src/locale/messages.fr.xlf --missing-translation error
-```
-
-When you build your application for a specific locale, it is probably a good idea to change
-the output path with the command `--output-path` in order to save the files to a different location.
-
-```sh
-ng build --aot --output-path dist/fr --locale fr --i18n-format xlf --i18n-file src/locale/messages.fr.xlf --missing-translation error
-```
-
-If you end up serving this specific version from a subdirectory, you can also change
-the base url used by your application with the command `--base-href`.
-
-For example if the french version of your application is served from https://myapp.com/fr/
-then you would build the french version like this:
-
-```sh
-ng build --aot --output-path dist/fr --base-href /fr/ --locale fr --i18n-format xlf --i18n-file src/locale/messages.fr.xlf --missing-translation error
-```
-
-If you need more details about how to create scripts to generate the app in multiple
-languages and how to setup Apache 2 to serve them from different subdirectories,
-you can read [this great tutorial](https://medium.com/@feloy/deploying-an-i18n-angular-app-with-angular-cli-fc788f17e358#.1xq4iy6fp)

-# Linked libraries
-
-While working on a library, it is common to use [npm link](https://docs.npmjs.com/cli/link) to
-avoid reinstalling the library on every build.
-
-While this is very useful there are a few caveats to keep in mind.
-
-## The library needs to be AOT compatible
-
-Angular CLI does static analysis even without the `--aot` flag in order to detect lazy-loade routes.
-If your library is not AOT compatible, you will likely get a static analysis error.
-
-## The library still needs to be rebuilt on every change
-
-Angular libraries are usually built using TypeScript and thus require to be built before they
-are published.
-For simple cases, a linked library might work even without a build step, but this is the exception
-rather than the norm.
-
-If a library is not being built using its own build step, then it is being compiled by the
-Angular CLI build system and there is no guarantee that it will be correctly built.
-Even if it works on development it might not work when deployed.
-
-When linking a library remember to have your build step running in watch mode and the library's
-`package.json` pointing at the correct entry points (e.g. 'main' should point at a `.js` file, not
-a `.ts` file).
-
-## Use TypesScript path mapping for Peer Dependencies
-
-Angular libraries should list all `@angular/*` dependencies as
-[Peer Dependencies](https://nodejs.org/en/blog/npm/peer-dependencies/).
-This insures that, when modules ask for Angular, they all get the exact same module.
-If a library lists `@angular/core` in `dependencies` instead of `peerDependencies` then it might
-get a *different* Angular module instead, which will cause your application to break.
-
-While developing a library, you'll need to have all of your peer dependencies also installed
-via `devDependencies` - otherwise you could not compile.
-A linked library will then have it's own set of Angular libraries that it is using for building,
-located in it's `node_modules` folder.
-This can cause problems while building or running your application.
-
-To get around this problem you can use the TypeScript
-[path mapping](https://www.typescriptlang.org/docs/handbook/module-resolution.html#path-mapping).
-With it, you can tell TypeScript that it should load some modules from a specific location.
-
-You should list all the peer dependencies that your library uses in `./tsconfig.json`, pointing
-them at the local copy in the apps `node_modules` folder.
-This ensures that you all will always load the local copies of the modules your library asks for.
-
-```
-{
-  "compilerOptions": {
-    // ...
-    // Note: these paths are relative to `baseUrl` path.
-    "paths": {
-      "@angular/*": [
-        "../node_modules/@angular/*"
-      ]
-    }
-  }
-}

-# Moving your project to Angular CLI
-
-The easiest way to move an existing project to Angular CLI is to copy your
-application files into a new, empty CLI project.
-
-Let's see how to do it step by step.
-Here we use a project made with the [official QuickStart](https://github.com/angular/quickstart)
-as an example, but you should be able to adjust these instructions to other setups.
-
-Note for Windows users: we show unix commands here like `cp -r` to copy and `rm -rf` to delete files.
-Windows does not have these commands so use Explorer instead.
-
-Start with preparing your existing project folder. We'll refer to it as `awesome-app`.
-- commit and push your existing changes.
-- clean your folder from temporary files and ignored files using `git clean -fdx`.
-- rename your project folder to `old-awesome-app`.
-
-Now make a new project on the same parent folder as `old-awesome-app` using Angular CLI.
-- Verify you have the [Angular CLI prerequisites](https://github.com/angular/angular-cli#prerequisites).
-- Install the CLI globally: `npm install -g @angular/cli`.
-- Make a new app: `ng new awesome-app`.
-- Move into the folder: `cd awesome-app`.
-- Test your app works: `ng serve --open`.
-
-Copy over your app files.
-- Remove the existing app: `rm -rf src/app src/styles.css src/index.html e2e`.
-- Copy `src/app/`, `src/index.html`, `src/styles.css` and `e2e/` from your old app.
-If you don't have a `src/` folder then these files and folders should be
-at the root of the old project instead.
-```
-cp -r ../old-awesome-app/src/app ./src/app
-cp ../old-awesome-app/src/index.html ./src/index.html
-cp ../old-awesome-app/src/styles.css ./src/styles.css
-cp -r ../old-awesome-app/e2e ./e2e/
-```
-- Don't copy `../old-awesome-app/src/main.ts`. Instead compare it to the new `./src/main.ts`
-and manually copy any extra code the old one has.
-- Compare `../old-awesome-app/package.json` to the new `./package.json` and add in your
-third party libraries and `@types/*` packages, project descriptions and any other fields.
-- Run `npm install` to install any packages you added.
-- Copy over any other files your app needs like images into `src/assets`.
-Adjust paths on your app to use this folder e.g. `<img src='assets/my-image.jpg>`.
-
-There are a few adjustments you need to do to use the CLI build system.
-- Change any absolute paths you have for `templateUrl`, `styleUrls` or lazy loaded NgModules to
-relative paths instead.
-- Remove any `module.id` that you have in `@Component` metadata. They aren't needed in the CLI.
-- Polyfills are listed in `./src/polyfills.ts` so remove `core-js` and `zone.js` from `index.html`.
-- SystemJS is not needed anymore, so remove it from `index.html` as well.
-- Instead of using `<script>` and `<link>` tags directly in `index.html`, use
-`.angular-cli.json` instead.
-  - Look for the `styles` array in `.angular-cli.json` and add in any CSS files you have in
-`src/index.html`. Use a relative path from `./src/`.
-  - Do the same for any remaining script tags as well, using the `scripts` array instead.
-
-The final step is to copy your git history so you can continue working without losing anything:
-- Copy over the git folder: `cp -r ../old-awesome-app/.git .git`
-- Commit and push your changes as normal.
-
-You can now delete `../old-awesome-app`, and you're done!
-
-The CLI runs static analysis on your code to ensure it's AOT ready, so you might run into a few
-new compilation errors that weren't there before.
-Check out this [handy list of AOT Do's and Dont's](https://github.com/rangle/angular-2-aot-sandbox#aot-dos-and-donts)
-if you get any unfamiliar errors.

-# Moving your project out of Angular CLI
-
-Each project is unique, and even though we try to cater to most setups in Angular CLI sometimes
-you need a custom setup.
-
-Even if you need to use a different build system, you can still use other Angular CLI features
-like `ng generate`, `ng lint`, `ng test` and `ng e2e` by leaving in `.angular-cli.json` and
-supporting files like `src/test.ts`.
-
-Moving out of the CLI is very similar to [Moving into the CLI](1-x/moving-into-the-cli).
-You'll have to make a brand new project using your new project seed, move your app files and
-cater to any changes in the build process.
-
-Start with preparing your existing project folder. We'll refer to it as `awesome-app`.
-- commit and push your existing changes.
-- clean your folder from temporary files and ignored files using `git clean -fdx`.
-- rename your project folder to `old-awesome-app`.
-
-Now make a new project on the same parent folder as `old-awesome-app`.
-- Make a new app using your new project seed in a new `awesome-app` folder.
-- Move into the folder: `cd awesome-app`.
-
-Copy over your app files.
-- Locate `app/`, `styles.css` and the end-to-end test folder in your new project.
-- Replace them with the corresponding files from `../old-awesome-app`.
-- If your styles are not in CSS, you'll need to convert them to CSS since the quickstart doesn't
-use style preprocessors. You can also add preprocessor support yourself.
-- Copy over the code your app needs from the `environments/` folder, if any.
-You'll have to find another way to switch environments on the Quickstart.
-- Don't copy `../old-awesome-app/src/main.ts`. It contains custom logic for the CLI
-`environments` feature. Instead compare code and take only what you need.
-- Do the same for `index.html`.
-- Compare `../old-awesome-app/package.json` to the new `./package.json` and add in your
-third party libraries and `@types/*` packages, project descriptions and any other fields.
-- Run `npm install` to install any packages you added.
-- Copy over any other files your app needs like images, icons, etc.
-
-You might also need to make adjustments to conform to your new build system.
-- The CLI only allows relative paths in `templateUrl`, `styleUrls` or lazy loaded NgModules.
-You might need to change these.
-- Polyfills are listed in `../old-awesome-app/src/polyfills.ts`. Incorporate these into the new
-project.
-- The CLI lists used `<script>` and `<link>` tags in the `.angular-cli.json` `scripts`
-and `styles` array. Check import these in your new project and add them accordingly.
-
-The final step is to copy your git history so you can continue working without losing anything:
-- Copy over the git folder: `cp -r ../old-awesome-app/.git .git`
-- Commit and push your changes as normal.
-
-You can now delete `../old-awesome-app`, and you're done!
-
-Every project seed does things slightly different so if you are running into problems be sure
-to ask in their issue tracker.

-You use the `apps` array in `.angular-cli.json` to list files and folders you want to use for different apps.
-
-By default one app is created when then new project is created and `apps` array looks like:
-```
-"apps": [
-  {
-    "root": "src",
-    ...
-    "main": "main.ts",
-    "polyfills": "polyfills.ts",
-    "test": "test.ts",
-    "tsconfig": "tsconfig.app.json",
-    "testTsconfig": "tsconfig.spec.json",
-    "prefix": "app",
-    ...
-  }
-],
-```
-
-To create another app you can copy the app object and then change the values for the options you want to change. eg. If I want to create another app with different `main`, `polyfills`, `test` and `prefix` and keep other configurations such as `assets`, `styles`, `environment` etc. same. I can add it to apps array as below.
-```
-"apps": [
-  {
-    "root": "src",
-    ...
-    "main": "main.ts",
-    "polyfills": "polyfills.ts",
-    "test": "test.ts",
-    "tsconfig": "tsconfig.app.json",
-    "testTsconfig": "tsconfig.spec.json",
-    "prefix": "app",
-    ...
-  },
-  {
-    "root": "src",
-    ...
-    "main": "main2.ts",
-    "polyfills": "polyfills2.ts",
-    "test": "test2.ts",
-    "tsconfig": "tsconfig.app.json",
-    "testTsconfig": "tsconfig.spec.json",
-    "prefix": "app2",
-    ...
-  }  
-],
-```
-Now we can `serve`, `build` etc. both the apps by passing the app index with the commands. By default, it will pick the first app only.
-
-To serve the first app: `ng serve --app=0` or `ng serve --app 0`
-
-To serve the second app: `ng serve --app=1` or `ng serve --app 1`
-
-You can also add the `name` property to the app object in `apps` array and then pass it to commands to distinguish between different applications.
-```
-"apps": [
-  {
-    "name": "app1",
-    "root": "src",
-    "outDir": "dist",
-....
-```
-To serve application by name `ng serve --app=app1` or `ng serve --app app1`.

-# Proxy To Backend
-
-Using the [proxying support](https://webpack.js.org/configuration/dev-server/#devserver-proxy) in webpack's dev server we can highjack certain URLs and send them to a backend server.
-We do this by passing a file to `--proxy-config`
-
-Say we have a server running on `http://localhost:3000/api` and we want all calls to `http://localhost:4200/api` to go to that server.
-
-We create a file next to our project's `package.json` called `proxy.conf.json` with the content
-
-```json
-{
-  "/api": {
-    "target": "http://localhost:3000/",
-    "secure": false
-  }
-}
-```
-
-You can read more about what options are available [here](https://webpack.js.org/configuration/dev-server/#devserver-proxy).
-
-We can then edit the `package.json` file's start script to be
-
-```json
-"start": "ng serve --proxy-config proxy.conf.json",
-```
-
-Now in order to run our dev server with our proxy config, we can simply call `npm start`.
-
-**After each edit to the proxy.conf.json file remember to relaunch the `npm start` process to make your changes effective.**
-
-### Rewriting the URL path
-
-One option that comes up a lot is rewriting the URL path for the proxy. This is supported by the `pathRewrite` option.
-
-Say we have a server running on `http://localhost:3000` and we want all calls to `http://localhost:4200/api` to go to that server.
-
-In our `proxy.conf.json` file, we add the following content
-
-```json
-{
-  "/api": {
-    "target": "http://localhost:3000/",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    }
-  }
-}
-```
-
-If you need to access a backend that is not on localhost, you will need to add the `changeOrigin` option as follows:
-
-```json
-{
-  "/api": {
-    "target": "http://npmjs.org/",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    },
-    "changeOrigin": true
-  }
-}
-```
-
-To help debug whether or not your proxy is working properly, you can also add the `logLevel` option as follows:
-
-```json
-{
-  "/api": {
-    "target": "http://localhost:3000/",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    },
-    "logLevel": "debug"
-  }
-}
-```
-
-Possible options for `logLevel` include `debug`, `info`, `warn`, `error`, and `silent` (default is `info`)
-
-
-### Multiple entries
-
-If you need to proxy multiple entries to the same target define the configuration in `proxy.conf.js` instead of `proxy.conf.json` e.g.
-
-```js
-const PROXY_CONFIG = [
-    {
-        context: [
-            "/my",
-            "/many",
-            "/endpoints",
-            "/i",
-            "/need",
-            "/to",
-            "/proxy"
-        ],
-        target: "http://localhost:3000/",
-        secure: false
-    }
-]
-
-module.exports = PROXY_CONFIG;
-```
-
-and make sure to point to the right file
-
-```json
-"start": "ng serve --proxy-config proxy.conf.js",
-```
-
-### Bypass the Proxy
-
-If you need to optionally bypass the proxy, or dynamically change the request before it's sent,  define the configuration in proxy.conf.js e.g.
-
-```js
-const PROXY_CONFIG = {
-    "/api/proxy": {
-        "target": "http://localhost:3000/",
-        "secure": false,
-        "bypass": function (req, res, proxyOptions) {
-            if (req.headers.accept.indexOf("html") !== -1) {
-                console.log("Skipping proxy for browser request.");
-                return "/index.html";
-            }
-            req.headers["X-Custom-Header"] = "yes";
-        }
-    }
-}
-
-module.exports = PROXY_CONFIG;
-```
-
-again, make sure to point to the right file
-
-```json
-"start": "ng serve --proxy-config proxy.conf.js",
-```

-# Generating a route
-
-The CLI supports routing in several ways:
-
-- We include the `@angular/router` NPM package when creating or initializing a project.
-
-- When you generate a module, you can use the `--routing` option like `ng g module my-module --routing`  to create a separate file `my-module-routing.module.ts` to store the module routes.
-
-  The file includes an empty `Routes` object that you can fill with routes to different components and/or modules.
-
-- You can use the `--routing` option with `ng new` to create a `app-routing.module.ts` file when you create or initialize a project.

-# 3rd Party Library Installation
-
-Simply install your library via `npm install lib-name --save` and import it in your code.
-
-If the library does not include typings, you can install them using npm:
-
-```bash
-npm install d3 --save
-npm install @types/d3 --save-dev
-```
-
-Then open `src/tsconfig.app.json` and add it to the `types` array:
-
-```
-"types":[
-  "d3"
-]
-```
-
-If the library you added typings for is only to be used on your e2e tests,
-instead use `e2e/tsconfig.e2e.json`.
-The same goes for unit tests and `src/tsconfig.spec.json`.
-
-If the library doesn't have typings available at `@types/`, you can still use it by
-manually adding typings for it:
-
-1. First, create a `typings.d.ts` file in your `src/` folder. This file will be automatically included as global type definition.
-
-2. Then, in `src/typings.d.ts`, add the following code:
-
-  ```typescript
-  declare module 'typeless-package';
-  ```
-
-3. Finally, in the component or file that uses the library, add the following code:
-
-  ```typescript
-  import * as typelessPackage from 'typeless-package';
-  typelessPackage.method();
-  ```
-
-Done. Note: you might need or find useful to define more typings for the library that you're trying to use.

-# Angular Universal Integration
-
-The Angular CLI supports generation of a Universal build for your application. This is a CommonJS-formatted bundle which can be `require()`'d into a Node application (for example, an Express server) and used with `@angular/platform-server`'s APIs to prerender your application.
-
----
-
-## Example CLI Integration:
-
-[Angular Universal-Starter](https://github.com/angular/universal-starter) - Clone the universal-starter for a working example.
-
----
-
-# Integrating Angular Universal into existing CLI Applications
-
-This story will show you how to set up Universal bundling for an existing `@angular/cli` project in 5 steps.
-
----
-
-## Install Dependencies
-
-Install `@angular/platform-server` into your project. Make sure you use the same version as the other `@angular` packages in your project.
-
-> You'll also need ts-loader (for your webpack build we'll show later) and @nguniversal/module-map-ngfactory-loader, as it's used to handle lazy-loading in the context of a server-render. (by loading the chunks right away)
-
-```bash
-$ npm install --save @angular/platform-server @nguniversal/module-map-ngfactory-loader ts-loader
-```
-
-## Step 1: Prepare your App for Universal rendering
-
-The first thing you need to do is make your `AppModule` compatible with Universal by adding `.withServerTransition()` and an application ID to your `BrowserModule` import:
-
-
-### src/app/app.module.ts:
-
-```javascript
-@NgModule({
-  bootstrap: [AppComponent],
-  imports: [
-    // Add .withServerTransition() to support Universal rendering.
-    // The application ID can be any identifier which is unique on
-    // the page.
-    BrowserModule.withServerTransition({appId: 'my-app'}),
-    ...
-  ],
-
-})
-export class AppModule {}
-```
-
-Next, create a module specifically for your application when running on the server. It's recommended to call this module `AppServerModule`.
-
-This example places it alongside `app.module.ts` in a file named `app.server.module.ts`:
-
-
-### src/app/app.server.module.ts:
-
-You can see here we're simply Importing everything from AppModule, followed by ServerModule.
-
-> One important thing to Note: We need `ModuleMapLoaderModule` to help make Lazy-loaded routes possible during Server-side renders with the Angular-CLI.
-
-```typescript
-import {NgModule} from '@angular/core';
-import {ServerModule} from '@angular/platform-server';
-import {ModuleMapLoaderModule} from '@nguniversal/module-map-ngfactory-loader';
-
-import {AppModule} from './app.module';
-import {AppComponent} from './app.component';
-
-@NgModule({
-  imports: [
-    // The AppServerModule should import your AppModule followed
-    // by the ServerModule from @angular/platform-server.
-    AppModule,
-    ServerModule,
-    ModuleMapLoaderModule // <-- *Important* to have lazy-loaded routes work
-  ],
-  // Since the bootstrapped component is not inherited from your
-  // imported AppModule, it needs to be repeated here.
-  bootstrap: [AppComponent],
-})
-export class AppServerModule {}
-```
-
----
-## Step 2: Create a server "main" file and tsconfig to build it
-
-Create a main file for your Universal bundle. This file only needs to export your `AppServerModule`. It can go in `src`. This example calls this file `main.server.ts`:
-
-### src/main.server.ts:
-
-```typescript
-export { AppServerModule } from './app/app.server.module';
-```
-
-Copy `tsconfig.app.json` to `tsconfig.server.json` and change it to build with a `"module"` target of `"commonjs"`.
-
-Add a section for `"angularCompilerOptions"` and set `"entryModule"` to your `AppServerModule`, specified as a path to the import with a hash (`#`) containing the symbol name. In this example, this would be `app/app.server.module#AppServerModule`.
-
-### src/tsconfig.server.json:
-
-```javascript
-{
-  "extends": "../tsconfig.json",
-  "compilerOptions": {
-    "outDir": "../out-tsc/app",
-    "baseUrl": "./",
-    // Set the module format to "commonjs":
-    "module": "commonjs",
-    "types": []
-  },
-  "exclude": [
-    "test.ts",
-    "**/*.spec.ts"
-  ],
-  // Add "angularCompilerOptions" with the AppServerModule you wrote
-  // set as the "entryModule".
-  "angularCompilerOptions": {
-    "entryModule": "app/app.server.module#AppServerModule"
-  }
-}
-```
-
----
-## Step 3: Create a new project in `.angular-cli.json`
-
-In `.angular-cli.json` there is an array under the key `"apps"`. Copy the configuration for your client application there, and paste it as a new entry in the array, with an additional key `"platform"` set to `"server"`.
-
-Then, remove the `"polyfills"` key - those aren't needed on the server, and adjust `"main"`, and `"tsconfig"` to point to the files you wrote in step 2. Finally, adjust `"outDir"` to a new location (this example uses `dist-server`).
-
-### .angular-cli.json:
-
-```javascript
-{
-  ...
-  "apps": [
-    {
-      // Keep your original application config intact here, this is app 0
-      // -EXCEPT- for outDir, update it to dist/browser
-      "outDir": "dist/browser" // <-- update this
-    },
-    {
-      // This is your server app. It is app 1.
-      "platform": "server",
-      "root": "src",
-      // Build to dist/server instead of dist. This prevents
-      // client and server builds from overwriting each other.
-      "outDir": "dist/server",
-      "assets": [
-        "assets",
-        "favicon.ico"
-      ],
-      "index": "index.html",
-      // Change the main file to point to your server main.
-      "main": "main.server.ts",
-      // Remove polyfills.
-      // "polyfills": "polyfills.ts",
-      "test": "test.ts",
-      // Change the tsconfig to point to your server config.
-      "tsconfig": "tsconfig.server.json",
-      "testTsconfig": "tsconfig.spec.json",
-      "prefix": "app",
-      "styles": [
-        "styles.css"
-      ],
-      "scripts": [],
-      "environmentSource": "environments/environment.ts",
-      "environments": {
-        "dev": "environments/environment.ts",
-        "prod": "environments/environment.prod.ts"
-      }
-    }
-  ],
-  ...
-}
-
-```
-
-## Building the bundle
-
-With these steps complete, you should be able to build a server bundle for your application, using the `--app` flag to tell the CLI to build the server bundle, referencing its index of `1` in the `"apps"` array in `.angular-cli.json`:
-
-```bash
-# This builds the client application in dist/browser/
-$ ng build --prod
-...
-# This builds the server bundle in dist/server/
-$ ng build --prod --app 1 --output-hashing=false
-
-# outputs:
-Date: 2017-07-24T22:42:09.739Z
-Hash: 9cac7d8e9434007fd8da
-Time: 4933ms
-chunk {0} main.js (main) 9.49 kB [entry] [rendered]
-chunk {1} styles.css (styles) 0 bytes [entry] [rendered]
-```
-
----
-
-
-## Step 4: Setting up an Express Server to run our Universal bundles
-
-Now that we have everything set up to -make- the bundles, how we get everything running?
-
-PlatformServer offers a method called `renderModuleFactory()` that we can use to pass in our AoT'd AppServerModule, to serialize our application, and then we'll be returning that result to the Browser.
-
-```typescript
-app.engine('html', (_, options, callback) => {
-  renderModuleFactory(AppServerModuleNgFactory, {
-    // Our index.html
-    document: template,
-    url: options.req.url,
-    // DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
-    extraProviders: [
-      provideModuleMap(LAZY_MODULE_MAP)
-    ]
-  }).then(html => {
-    callback(null, html);
-  });
-});
-```
-
-You could do this, if you want complete flexibility, or use an express-engine with a few other built in features from [`@nguniversal/express-engine`](https://github.com/angular/universal/tree/master/modules/express-engine) found here.
-
-```typescript
-// It's used as easily as
-import { ngExpressEngine } from '@nguniversal/express-engine';
-
-app.engine('html', ngExpressEngine({
-  bootstrap: AppServerModuleNgFactory,
-  providers: [
-    provideModuleMap(LAZY_MODULE_MAP)
-  ]
-}));
-```
-
-Below we can see a TypeScript implementation of a -very- simple Express server to fire everything up.
-
-> Note: This is a very bare bones Express application, and is just for demonstrations sake. In a real production environment, you'd want to make sure you have other authentication and security things setup here as well. This is just meant just to show the specific things needed that are relevant to Universal itself. The rest is up to you!
-
-At the ROOT level of your project (where package.json / etc are), created a file named: **`server.ts`**
-
-### ./server.ts (root project level)
-
-```typescript
-// These are important and needed before anything else
-import 'zone.js/dist/zone-node';
-import 'reflect-metadata';
-
-import { renderModuleFactory } from '@angular/platform-server';
-import { enableProdMode } from '@angular/core';
-
-import * as express from 'express';
-import { join } from 'path';
-import { readFileSync } from 'fs';
-
-// Faster server renders w/ Prod mode (dev mode never needed)
-enableProdMode();
-
-// Express server
-const app = express();
-
-const PORT = process.env.PORT || 4000;
-const DIST_FOLDER = join(process.cwd(), 'dist');
-
-// Our index.html we'll use as our template
-const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();
-
-// * NOTE :: leave this as require() since this file is built Dynamically from webpack
-const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');
-
-const { provideModuleMap } = require('@nguniversal/module-map-ngfactory-loader');
-
-app.engine('html', (_, options, callback) => {
-  renderModuleFactory(AppServerModuleNgFactory, {
-    // Our index.html
-    document: template,
-    url: options.req.url,
-    // DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
-    extraProviders: [
-      provideModuleMap(LAZY_MODULE_MAP)
-    ]
-  }).then(html => {
-    callback(null, html);
-  });
-});
-
-app.set('view engine', 'html');
-app.set('views', join(DIST_FOLDER, 'browser'));
-
-// Server static files from /browser
-app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
-
-// All regular routes use the Universal engine
-app.get('*', (req, res) => {
-  res.render(join(DIST_FOLDER, 'browser', 'index.html'), { req });
-});
-
-// Start up the Node server
-app.listen(PORT, () => {
-  console.log(`Node server listening on http://localhost:${PORT}`);
-});
-```
-
-## Step 5: Setup a webpack config to handle this Node server.ts file and serve your application!
-
-Now that we have our Node Express server setup, we need to pack it and serve it!
-
-Create a file named `webpack.server.config.js` at the ROOT of your application.
-
-> This file basically takes that server.ts file, and takes it and compiles it and every dependency it has into `dist/server.js`.
-
-### ./webpack.server.config.js (root project level)
-
-```typescript
-const path = require('path');
-const webpack = require('webpack');
-
-module.exports = {
-  entry: {  server: './server.ts' },
-  resolve: { extensions: ['.js', '.ts'] },
-  target: 'node',
-  // this makes sure we include node_modules and other 3rd party libraries
-  externals: [/(node_modules|main\..*\.js)/],
-  output: {
-    path: path.join(__dirname, 'dist'),
-    filename: '[name].js'
-  },
-  module: {
-    rules: [
-      { test: /\.ts$/, loader: 'ts-loader' }
-    ]
-  },
-  plugins: [
-    // Temporary Fix for issue: https://github.com/angular/angular/issues/11580
-    // for "WARNING Critical dependency: the request of a dependency is an expression"
-    new webpack.ContextReplacementPlugin(
-      /(.+)?angular(\\|\/)core(.+)?/,
-      path.join(__dirname, 'src'), // location of your src
-      {} // a map of your routes
-    ),
-    new webpack.ContextReplacementPlugin(
-      /(.+)?express(\\|\/)(.+)?/,
-      path.join(__dirname, 'src'),
-      {}
-    )
-  ]
-}
-```
-
-**Almost there!**
-
-Now let's see what our resulting structure should look like, if we open up our `/dist/` folder we should see:
-
-```
-/dist/
-   /browser/
-   /server/
-```
-
-To fire up the application, in your terminal enter
-
-```bash
-node dist/server.js
-```
-
-:sparkles:
-
-Now lets create a few handy scripts to help us do all of this in the future.
-
-```json
-"scripts": {
-
-  // These will be your common scripts
-  "build:ssr": "npm run build:client-and-server-bundles && npm run webpack:server",
-  "serve:ssr": "node dist/server.js",
-
-  // Helpers for the above scripts
-  "build:client-and-server-bundles": "ng build --prod && ng build --prod --app 1 --output-hashing=false",
-  "webpack:server": "webpack --config webpack.server.config.js --progress --colors"
-}
-```
-
-In the future when you want to see a Production build of your app with Universal (locally), you can simply run:
-
-```bash
-npm run build:ssr && npm run serve:ssr
-```
-
-Enjoy!
-
-Once again to see a working version of everything, check out the [universal-starter](https://github.com/angular/universal-starter).

-# Using corporate proxy
-
-If you work behind a corporate proxy, the regular [backend proxy](https://github.com/angular/angular-cli/wiki/stories-proxy) configuration will not work if you try to proxy calls to any URL outside your local network.
-
-In this case, you can configure the backend proxy to redirect calls through your corporate proxy using an agent:
-
-```bash
-npm install --save-dev https-proxy-agent
-```
-
-Then instead of using a `proxy.conf.json` file, we create a file called `proxy.conf.js` with the content
-
-```js
-var HttpsProxyAgent = require('https-proxy-agent');
-var proxyConfig = [{
-  context: '/api',
-  target: 'http://your-remote-server.com:3000/',
-  secure: false
-}];
-
-function setupForCorporateProxy(proxyConfig) {
-  var proxyServer = process.env.http_proxy || process.env.HTTP_PROXY;
-  if (proxyServer) {
-    var agent = new HttpsProxyAgent(proxyServer);
-    console.log('Using corporate proxy server: ' + proxyServer);
-    proxyConfig.forEach(function(entry) {
-      entry.agent = agent;
-    });
-  }
-  return proxyConfig;
-}
-
-module.exports = setupForCorporateProxy(proxyConfig);
-```
-
-and edit the `package.json` file's start script accordingly
-
-```json
-"start": "ng serve --proxy-config proxy.conf.js",
-```
-
-This way if you have a `http_proxy` or `HTTP_PROXY` environment variable defined, an agent will automatically be added to pass calls through your corporate proxy when running `npm start`.

-
-## Overview
-`ng test` compiles the application into an output directory
-
-### Running unit tests
-
-```bash
-ng test
-```
-
-Tests will execute after a build is executed via [Karma](http://karma-runner.github.io/0.13/index.html), and it will automatically watch your files for changes. You can run tests a single time via `--watch=false` or `--single-run`.
-
-You can run tests with coverage via `--code-coverage`. The coverage report will be in the `coverage/` directory.

-
-# ng build
-
-## Overview
-`ng build` compiles the application into an output directory.
-
-```bash
-ng build [project]
-```
-
-### Creating a build
-
-```bash
-ng build
-```
-
-The build artifacts will be stored in the `dist/` directory.
-
-All commands that build or serve your project, `ng build/serve/e2e`, will delete the output
-directory (`dist/` by default).
-This can be disabled via the `--delete-output-path=false` option.
-
-### Base tag handling in index.html
-
-When building you can modify base tag (`<base href="http://github.com/">`) in your index.html with `--base-href your-url` option.
-
-```bash
-# Sets base tag href to /myUrl/ in your index.html
-ng build --base-href /myUrl/
-```
-
-### Bundling & Tree-Shaking
-
-All builds make use of bundling and limited tree-shaking, while `--prod` builds also run limited
-dead code elimination via UglifyJS.
-
-### `--build-optimizer` and `--vendor-chunk`
-
-When using Build Optimizer the vendor chunk will be disabled by default.
-You can override this with `--vendor-chunk=true`.
-
-Total bundle sizes with Build Optimizer are smaller if there is no separate vendor chunk because
-having vendor code in the same chunk as app code makes it possible for Uglify to remove more unused
-code.
-
-### CSS resources
-
-Resources in CSS, such as images and fonts, will be copied over automatically as part of a build.
-If a resource is less than 10kb it will also be inlined.
-
-You'll see these resources be outputted and fingerprinted at the root of `dist/`.
-
-### ES2015 support
-
-To build in ES2015 mode, edit `./tsconfig.json` to use `"target": "es2015"` (instead of `es5`).
-
-This will cause application TypeScript and Uglify be output as ES2015, and third party libraries
-to be loaded through the `es2015` entry in `package.json` if available.
-
-Be aware that JIT does not support ES2015 and so you should build/serve your app with `--aot`.
-See https://github.com/angular/angular-cli/issues/7797 for details.

-**NOTE: this documentation is for Angular CLI 6. For Angular CLI Version 7 go [here](https://angular.io/cli) and 1.x go [here](1-x-home) instead.**
-
-### Overview
-The Angular CLI is a tool to initialize, develop, scaffold  and maintain [Angular](https://angular.io) applications
-
-### Getting Started
-To install the Angular CLI:
-```
-npm install -g @angular/cli
-```
-
-> If you get an error installing the CLI, this is an issue with your local npm setup on your machine, not a problem in Angular CLI.
-> Please have a look at the [fixing npm permissions page](https://docs.npmjs.com/getting-started/fixing-npm-permissions), [common errors page](https://docs.npmjs.com/troubleshooting/common-errors), [npm issue tracker](https://github.com/npm/npm/issues), or open a new issue if the problem you are experiencing isn't known.
-> To install a different version, see below.
-
-Generating and serving an Angular project via a development server
-[Create](new) and [run](serve) a new project:
-```
-ng new my-project
-cd my-project
-ng serve
-```
-Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
-
-### Bundling
-
-All builds make use of bundling, and using the `--prod` flag in  `ng build --prod`
-or `ng serve --prod` will also make use of uglifying and tree-shaking functionality.
-
-### Running unit tests
-
-```bash
-ng test
-```
-
-Tests will execute after a build is executed via [Karma](http://karma-runner.github.io/0.13/index.html), and it will automatically watch your files for changes. You can run tests a single time via `--watch=false` or `--single-run`.
-
-### Running end-to-end tests
-
-```bash
-ng e2e
-```
-
-Before running the tests make sure you are serving the app via `ng serve`.
-End-to-end tests are run via [Protractor](http://www.protractortest.org/).
-
-### Additional Commands
-* [ng new](new)
-* [ng serve](serve)
-* [ng generate](generate)
-* [ng lint](lint)
-* [ng test](test)
-* [ng e2e](e2e)
-* [ng build](build)
-* [ng get/ng set](config)
-* [ng doc](doc)
-* [ng xi18n](xi18n)
-* [ng update](update)
-
-## Angular CLI Workspace Schema
-* [Angular CLI workspace file (angular.json) schema](angular-workspace)
-
-### Additional Information
-There are several [stories](stories) which will walk you through setting up
-additional aspects of Angular applications.
-
-### Installing a specific version
-The CLI is installed both globally (the command above with the `-g` argument to `npm install`) and also within the project. To install a different version of the CLI, you can just update the version locally within your project. The globally installed package will always delegate to the local one.
-
-There are several different versions available at any time:
-- Install a previous version, maybe because of a bug in the latest version. For example to get 6.0.2: `npm install @angular/cli@6.0.2`
-- Install the pre-release of a newer minor/major version, to try new features. For example to get 7.0.0-beta.3: `npm install @angular/cli@next`. Note that the `@next` version is only useful during beta periods.
-- Install a snapshot build from the latest passing run of our CI (angular-cli/master). This is useful if an issue was just fixed or a new feature just landed on master, but is not yet released: `npm install @angular/cli@github:angular/cli-builds` (or maybe better, find the particular SHA that you want to try: 
-`npm install @angular/cli@github:angular/cli-builds#0123456789abcdef`)

-
-# Angular CLI migration guide
-
-In this migration guide we'll be looking at some of the major changes to CLI projects in the
-last two months.
-
-Most of these changes were not breaking changes and your project should work fine without them.
-
-But if you've been waiting for the perfect time to update, this is it!
-Along with major rebuild speed increases, we've been busy adding a lot of features.
-
-Documentation has also completely moved to [the wiki](https://github.com/angular/angular-cli/wiki).
-The new [Stories](https://github.com/angular/angular-cli/wiki/stories) section covers common usage
-scenarios, so be sure to have a look!
-
-Below are the changes between a project generated two months ago, with `1.0.0-beta.24` and
-a `1.0.0` project.
-If you kept your project up to date you might have a lot of these already.
-
-You can find more details about changes between versions in [the releases tab on GitHub](https://github.com/angular/angular-cli/releases).
-
-If you prefer, you can also generate a new project in a separate folder using
- `ng new upgrade-project --skip-install` and compare the differences.
-
-## @angular/cli
-
-Angular CLI can now be found on NPM under `@angular/cli` instead of `angular-cli`, and upgrading is a simple 3 step process:
-
-1. Uninstall old version
-2. Update node/npm if necessary
-3. Install new version
-
-### 1. Uninstall old version
-
-If you're using Angular CLI `beta.28` or less, you need to uninstall the `angular-cli` packages:
-```bash
-npm uninstall -g angular-cli          # Remove global package
-npm uninstall --save-dev angular-cli  # Remove from package.json
-```
-
-Otherwise, uninstall the  `@angular/cli` packages:
-```bash
-npm uninstall -g @angular/cli         # Remove global package
-npm uninstall --save-dev @angular/cli # Remove from package.json
-```
-
-Also purge the cache and local packages:
-```
-rm -rf node_modules dist # Use rmdir on Windows
-npm cache clean
-```
-
-At this point, you should not have Angular CLI on your system anymore. If invoking Angular CLI at the commandline reveals that it still exists on your system, you will have to manually remove it. See _Manually removing residual Angular CLI_.
-
-### 2. Update node/npm if necessary
-
-Angular CLI now has a minimum requirement of Node 6.9.0 or higher, together with NPM 3 or higher.
-
-If your Node or NPM versions do not meet these requirements, please refer to [the documentation](https://docs.npmjs.com/getting-started/installing-node) on how to upgrade. 
-
-### 3. Install the new version
-
-To update Angular CLI to a new version, you must update both the global package and your project's local package:
-
-```bash
-npm install -g @angular/cli@latest          # Global package
-npm install --save-dev @angular/cli@latest  # Local package
-npm install                                 # Restore removed dependencies
-```
-
-### Manually removing residual Angular CLI
-
-If you accidentally updated NPM before removing the old Angular CLI, you may find that uninstalling the package using `npm uninstall` is proving fruitless. This _could_ be because the global install (and uninstall) path changed between versions of npm from `/usr/local/lib` to `/usr/lib`, and hence, no longer searches through the old directory. In this case you'll have to remove it manually:
-
-`rm -rf /usr/local/lib/node_modules/@angular/cli`
-
-If the old Angular CLI package _still_ persists, you'll need to research how to remove it before proceeding with the upgrade.
-
-## .angular-cli.json
-
-`angular-cli.json` is now `angular.json`, but we still accept the old config file name.
-
-A few new properties have changed in it:
-
-### Schema
-
-Add the `$schema` property above project for handy IDE support on your config file:
-
-```
-"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
-```
-
-### Polyfills
-
-There is now a dedicated entry for polyfills ([#3812](https://github.com/angular/angular-cli/pull/3812))
-inside `apps[0].polyfills`, between `main` and `test`:
-
-```
-"main": "main.ts",
-"polyfills": "polyfills.ts",
-"test": "test.ts",
-```
-
-Add it and remove `import './polyfills.ts';` from `src/main.ts` and `src/test.ts`.
-
-We also added a lot of descriptive comments to the existing `src/polyfills.ts` file, explaining
-which polyfills are needed for what browsers.
-Be sure to check it out in a new project!
-
-### Environments
-
-A new `environmentSource` entry ([#4705](https://github.com/angular/angular-cli/pull/4705))
-replaces the previous source entry inside environments.
-
-To migrate angular-cli.json follow the example below:
-
-Before:
-```
-"environments": {
-  "source": "environments/environment.ts",
-  "dev": "environments/environment.ts",
-  "prod": "environments/environment.prod.ts"
-}
-```
-
-After:
-
-```
-"environmentSource": "environments/environment.ts",
-"environments": {
-  "dev": "environments/environment.ts",
-  "prod": "environments/environment.prod.ts"
-}
-```
-
-### Linting
-
-The CLI now uses the TSLint API ([#4248](https://github.com/angular/angular-cli/pull/4248))
-to lint several TS projects at once.
-
-There is a new `lint` entry in `.angular-cli.json` between `e2e` and `test` where all linting
-targets are listed:
-
-```
-"e2e": {
-  "protractor": {
-    "config": "./protractor.conf.js"
-  }
-},
-"lint": [
-  {
-    "project": "src/tsconfig.app.json"
-  },
-  {
-    "project": "src/tsconfig.spec.json"
-  },
-  {
-    "project": "e2e/tsconfig.e2e.json"
-  }
-],
-"test": {
-  "karma": {
-    "config": "./karma.conf.js"
-  }
-},
-```
-
-### Generator defaults
-
-Now you can list generator defaults per generator ([#4389](https://github.com/angular/angular-cli/pull/4389))
-in `defaults`.
-
-Instead of:
-```
-"defaults": {
-  "styleExt": "css",
-  "prefixInterfaces": false,
-  "inline": {
-    "style": false,
-    "template": false
-  },
-  "spec": {
-    "class": false,
-    "component": true,
-    "directive": true,
-    "module": false,
-    "pipe": true,
-    "service": true
-  }
-}
-```
-
-You can instead list the flags as they appear on [the generator command](https://github.com/angular/angular-cli/wiki/generate-component):
-```
-"defaults": {
-  "styleExt": "css",
-  "component": {
-    "inlineTemplate": false,
-    "spec": true
-  }
-}
-```
-
-## One tsconfig per app
-
-CLI projects now use one tsconfig per app ([#4924](https://github.com/angular/angular-cli/pull/4924)).
-
-- `src/tsconfig.app.json`: configuration for the Angular app.
-```

-    "types":[
-      "jasmine",
-      "node"
-    ]
-  }
-}
-
-```
-
-There is an additional root-level `tsconfig.json` that is used for IDE integration.
-```
-{
-  "compileOnSave": false,
-  "compilerOptions": {
-    "outDir": "./dist/out-tsc",

-    ],
-    "lib": [
-      "es2017",
-      "dom"
-    ]
-  }
-}
-```
-
-You can delete `e2e/tsconfig.json` and `src/tsconfig.json` after adding these.
-
-Also update `.angular-cli.json` to use them inside `apps[0]`:
-
-```
-"tsconfig": "tsconfig.app.json",
-"testTsconfig": "tsconfig.spec.json",
-```
-
-Then update `protractor.conf.js` to use the e2e config as well:
-```
-beforeLaunch: function() {
-  require('ts-node').register({
-    project: 'e2e/tsconfig.e2e.json'
-  });
-},
-```
-
-These configs have an `types` array where you should add any package you install via `@types/*`.
-This array helps keep typings isolated to the apps that really need them and avoid problems with
-duplicate typings.
-
-For instance, the unit test `tsconfig` has `jasmine` and `node`, which correspond to
-`@types/jasmine` and `@types/node`.
-Add any typings you've installed to the appropriate `tsconfig` as well.
-
-## typings.d.ts
-
-There's a new `src/typings.d.ts` file that serves two purposes:
-- provides a centralized place for users to add their own custom typings
-- makes it easy to use components that use `module.id`, present in the documentation and in snippets
-
-```
-/* SystemJS module definition */
-declare var module: NodeModule;
-interface NodeModule {
-  id: string;
-}
-```
-
-## package.json

-# App shell
-
-App shell is a way to render a portion of your application via a route at build time. This gives users a meaningful first paint of your application because the browser does not need to initialize any JavaScript, just rendering the HTML.
-
-## Steps
-
-### Step 1: Prepare the application
-
-An application must be set up with routing. This can be accomplished by running:
-```
-ng new my-app --routing
-```
-Or if you have an existing application you can manually add routing by including the RouterModule and defining a `<router-outlet>` within your app.
-
-
-### Step 2: Create the app shell
-```
-ng generate app-shell --client-project my-app --universal-project server-app
-```
-`my-app` is the name of your client application
-`server-app` is the name of the universal (or server) application
-
-After running this command you will notice that the `angular.json` configuration file has been updated. Two new targets were added (and a few other changes):
-```
-"server": {
-  "builder": "@angular-devkit/build-angular:server",
-  "options": {
-    "outputPath": "dist/my-app-server",
-    "main": "src/main.server.ts",
-    "tsConfig": "src/tsconfig.server.json"
-  }
-},
-"app-shell": {
-  "builder": "@angular-devkit/build-angular:app-shell",
-  "options": {
-    "browserTarget": "my-app:build",
-    "serverTarget": "my-app:server",
-    "route": "shell"
-  }
-}
-```
-
-### Step 3: Verify the app is built with the shell content
-
-build with the app shell target
-```
-ng run my-app:app-shell
-```
-If you would like to build for production you should run the following command
-```
-ng run my-app:app-shell:production
-ng run my-app:app-shell --configuration production
-```
-
-Verify the build output
-Open dist/index.html
-look for text "app-shell works!" which verifies that the app shell route was rendered as part of the output

-**Documentation below is for CLI version 6 and we no longer accept PRs to improve this. For version 7 see [here](https://angular.io/guide/build#configuring-application-environments)**.
-
-# Application Environments
-
-In Angular CLI you can configure the build system to replace existing files for your intended
-environment.
-
-## Configuring available file replacements
-
-`angular.json` contains an **fileReplacements** section within the production configuration of the
-build target. By default, this looks like:
-
-``` json
-"configurations": {
-  "production": {
-    "fileReplacements": [
-      {
-        "replace": "src/environments/environment.ts",
-        "with": "src/environments/environment.prod.ts"
-      }
-    ],
-    ...
-```
-
-This means that when you use your production configuration (via `ng build --prod` or
-`ng build --configuration=production`), the `src/environments/environment.ts` file will be replaced
-with `src/environments/environment.prod.ts`.
-
-This is useful for using different code or variables when creating a new build.
-By default no file is replaced in the build.
-
-You can add additional configurations as required.
-To add a **staging** environment, create a copy of `src/environments/environment.ts` called `src/environments/environment.staging.ts`, then add a `staging` configuration to `angular.json`:
-
-```json
-"configurations": {
-  "production": { ... },
-  "staging": {
-    "fileReplacements": [
-      {
-        "replace": "src/environments/environment.ts",
-        "with": "src/environments/environment.staging.ts"
-      }
-    ]
-  }
-}
-```
-
-You can add more configuration options to this environment as well.
-Any option that your build supports can be overriden in a configuration.
-
-To build using the staging configuration, run `ng build --configuration=staging`.
-
-To serve using the staging configuration, you must edit the `serve` target to use the `staging`
-build configuration:
-```json
-"serve": {
-  "builder": "@angular-devkit/build-angular:dev-server",
-  "options": {
-    "browserTarget": "your-project-name:build"
-  },
-  "configurations": {
-    "production": {
-      "browserTarget": "your-project-name:build:production"
-    },
-    "staging": {
-      "browserTarget": "your-project-name:build:staging"
-    }
-  }
-},
-```
-
-## Changing environment-specific files
-
-`environment.ts` contains the default settings.  If you take a look at this file, it should look like:
-
-``` TypeScript
-export const environment = {
-  production: false
-};
-```
-
-If you compare this to `environment.prod.ts`, which looks like:
-
-``` TypeScript
-export const environment = {
-  production: true
-};
-```
-
-You can add further variables, either as additional properties on the `environment` object, or as separate objects, for example:
-
-``` TypeScript
-export const environment = {
-  production: false,
-  apiUrl: 'http://my-api-url/'
-};
-```
-
-## Using environment-specific variables in your application
-
-Given the following application structure:
-
-```
-└── src
-    └── app
-        ├── app.component.html
-        └── app.component.ts
-    └── environments
-        ├── environment.prod.ts
-        ├── environment.staging.ts
-        └── environment.ts
-```
-
-Using environment variables inside of `app.component.ts` might look something like this:
-
-``` TypeScript
-import { Component } from '@angular/core';
-import { environment } from './../environments/environment';
-
-@Component({
-  selector: 'app-root',
-  templateUrl: './app.component.html',
-  styleUrls: ['./app.component.css']
-})
-export class AppComponent {
-  constructor() {
-    console.log(environment.production); // Logs false for default environment
-  }
-  title = 'app works!';
-}
-```
-
-You will always import the original environments file.
-This way the build system can replace the original in each configuration.

-# Project assets
-
-You use the `assets` array inside the build target in `angular.json` to list files or folders
-you want to copy as-is when building your project. if you think you need to exclude files, 
-consider not putting that thing in the assets
-
-By default, the `src/assets/` folder and `src/favicon.ico` are copied over.
-
-```json
-"assets": [
-  "src/assets",
-  "src/favicon.ico"
-]
-```
-
-You can also further configure assets to be copied by using objects as configuration.
-
-The array below does the same as the default one:
-
-```json
-"assets": [
-  { "glob": "**/*", "input": "src/assets/", "output": "/assets/" },
-  { "glob": "favicon.ico", "input": "src/", "output": "/" },
-]
-```
-
-- `glob` is a [node-glob](https://github.com/isaacs/node-glob) using `input` as base directory.
-- `input` is relative to the workspace root.
-- `ignore` is a list of globs to ignore from copying.
-- `output` is relative to `outDir` (`dist/project-name` default).
-
- You can use this extended configuration to copy assets from outside your project.
- For instance, you can copy assets from a node package:
-
- ```json
-"assets": [
-  { "glob": "**/*", "input": "./node_modules/some-package/images", "output": "/some-package/" },
-]
-```
-
-You can ignore certain files from copying by using the `ignore` option:
- ```json
-"assets": [
-  { "glob": "**/*", "input": "src/assets/", "ignore": ["**/*.svg"], "output": "/assets/" },
-]
-```
-
-The contents of `node_modules/some-package/images/` will be available in `dist/some-package/`. 
-
-## Writing assets outside of `dist/`
-
-Because of the security implications, the CLI will always refuse to write files outside of
-the project output path.

-
-# Change target browsers for Autoprefixer
-
-Currently, the CLI uses [Autoprefixer](https://github.com/postcss/autoprefixer) to ensure compatibility
-with different browser and browser versions. You may find it necessary to target specific browsers
-or exclude certain browser versions from your build.
-
-Internally, Autoprefixer relies on a library called [Browserslist](https://github.com/browserslist/browserslist)
-to figure out which browsers to support with prefixing.
-
-There are a few ways to tell Autoprefixer what browsers to target:
-
-### Add a browserslist property to the `package.json` file
-```
-"browserslist": [
-  "> 1%",
-  "last 2 versions"
-]
-```
-
-### Add a new file to the project directory called `.browserslistrc`
-```
-### Supported Browsers
-
-> 1%
-last 2 versions
-```
-
-Autoprefixer will look for the configuration file/property to use when it prefixes your css.
-Check out the [browserslist repo](https://github.com/browserslist/browserslist) for more examples of how to target
-specific browsers and versions.
-
-_Side note:_
-Those who are seeking to produce a [progressive web app](https://developers.google.com/web/progressive-web-apps/) and are using [Lighthouse](https://developers.google.com/web/tools/lighthouse/) to grade the project will
-need to add the following browserslist config to their package.json file to eliminate the [old flexbox](https://developers.google.com/web/tools/lighthouse/audits/old-flexbox) prefixes:
-
-`package.json` config:
-```
-"browserslist": [
-  "last 2 versions",
-  "not ie <= 10",
-  "not ie_mob <= 10"

-
-# Code Coverage
-
-With the Angular CLI we can run unit tests as well as create code coverage reports. Code coverage reports allow us to see any parts of our code base that may not be properly tested by our unit tests.
-
-To generate a coverage report run the following command in the root of your project
-
-```bash
-ng test --watch=false --code-coverage
-```
-
-Once the tests complete a new `/coverage` folder will appear in the project. In your Finder or Windows Explorer open the `index.html` file. You should see a report with your source code and code coverage values.
-
-Using the code coverage percentages we can estimate how much of our code is tested. It is up to your team to determine how much code should be unit tested.
-
-## Code Coverage Enforcement
-
-If your team decides on a set minimum amount to be unit tested you can enforce this minimum with the Angular CLI. For example our team would like the code base to have a minimum of 80% code coverage. To enable this open the `karma.conf.js` and add the following in the `coverageIstanbulReporter:` key
-
-```javascript
-coverageIstanbulReporter: {
-  reports: [ 'html', 'lcovonly' ],
-  fixWebpackSourcePaths: true,
-  thresholds: {
-    statements: 80,
-    lines: 80,
-    branches: 80,
-    functions: 80
-  }
-}
-```
-
-The `thresholds` property will enforce a minimum of 80% code coverage when the unit tests are run in the project.
-
-Another option to simplify the usage of code coverage, instead of passing it via the command line every time. Is to set the value within the configuration file `angular.json`.
-
-```json
-  ...
-  "test": {
-    "options": {
-      "codeCoverage": true
-    }
-  }
-```
-
-This will produce code coverage results whenever tests are run for the project.

-**HMR is a webpack feature that is not officially supported by Angular. Community contributors can submit PRs against this page to add corrections, new information, or advice.**.
-
-# Configure Hot Module Replacement
-
-Hot Module Replacement (HMR) is a [webpack](https://webpack.js.org) feature to update code in a running app without rebuilding it.
-This results in faster updates and fewer full page-reloads.
-
-You can read more about HMR by visiting [this page](https://webpack.js.org/guides/hot-module-replacement/).
-
-In order to get HMR working with Angular CLI we first need to add a new environment and enable it.
-
-Next we need to update the bootstrap process of our app to enable the
-[@angularclass/hmr](https://github.com/gdi2290/angular-hmr) module.
-
-### Add environment for HMR
-
-Create a file called `src/environments/environment.hmr.ts` with the following contents:
-
-```typescript
-
-export const environment = {
- production: false,
- hmr: true
-};
-```
-
-Update `src/environments/environment.prod.ts` and add the `hmr: false` flag to the environment:
-
-```typescript
-export const environment = {
- production: true,
- hmr: false
-};
-```
-
-Update `src/environments/environment.ts` and add the `hmr: false` flag to the environment:
-
-```typescript
-export const environment = {
- production: false,
- hmr: false
-};
-```
-
-
-Update `angular.json` to include an hmr environment as explained [here](./application-environments)
-and add configurations within build and serve to enable hmr. Note that `<project-name>` here
-represents the name of the project you are adding this configuration to in `angular.json`.
-
-```json
-  "build": {
-    "configurations": {
-      ...
-      "hmr": {
-        "fileReplacements": [
-          {
-            "replace": "src/environments/environment.ts",
-            "with": "src/environments/environment.hmr.ts"
-          }
-        ]
-      }
-    }
-  },
-  ...
-  "serve": {
-    "configurations": {
-      ...
-      "hmr": {
-        "hmr": true,
-        "browserTarget": "<project-name>:build:hmr"
-      }
-    }
-  }
-```
-
-Add the necessary types to  `src/tsconfig.app.json`
-
-```json
-{
-  ...
-  "compilerOptions": {
-    ...
-    "types": ["node"]
-  },
-}
-```
-
-Run `ng serve` with the flag `--configuration hmr` to enable hmr and select the new environment:
-
-```bash
-ng serve --configuration hmr
-```
-
-Create a shortcut for this by updating  `package.json` and adding an entry to the script object:
-
-```json
-"scripts": {
-  ...
-  "hmr": "ng serve --configuration hmr"
-}
-```
-
-
-### Add dependency for @angularclass/hmr and configure app
-
-In order to get HMR working we need to install the dependency and configure our app to use it.
-
-
-Install the `@angularclass/hmr` module as a dev-dependency
-
-```bash
-$ npm install --save-dev @angularclass/hmr
-```
-
-
-Create a file called `src/hmr.ts` with the following content:
-
-```typescript
-import { NgModuleRef, ApplicationRef } from '@angular/core';
-import { createNewHosts } from '@angularclass/hmr';
-
-export const hmrBootstrap = (module: any, bootstrap: () => Promise<NgModuleRef<any>>) => {
-  let ngModule: NgModuleRef<any>;
-  module.hot.accept();
-  bootstrap().then(mod => ngModule = mod);
-  module.hot.dispose(() => {
-    const appRef: ApplicationRef = ngModule.injector.get(ApplicationRef);
-    const elements = appRef.components.map(c => c.location.nativeElement);
-    const makeVisible = createNewHosts(elements);
-    ngModule.destroy();
-    makeVisible();
-  });
-};
-```
-
-
-Update `src/main.ts` to use the file we just created:
-
-```typescript
-import { enableProdMode } from '@angular/core';
-import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
-
-import { AppModule } from './app/app.module';
-import { environment } from './environments/environment';
-
-import { hmrBootstrap } from './hmr';
-
-if (environment.production) {
-  enableProdMode();
-}
-
-const bootstrap = () => platformBrowserDynamic().bootstrapModule(AppModule);
-
-if (environment.hmr) {
-  if (module[ 'hot' ]) {
-    hmrBootstrap(module, bootstrap);
-  } else {
-    console.error('HMR is not enabled for webpack-dev-server!');
-    console.log('Are you using the --hmr flag for ng serve?');
-  }
-} else {
-  bootstrap().catch(err => console.log(err));
-}
-```
-
-
-### Starting the development environment with HMR enabled
-
-Now that everything is set up we can run the new configuration:
-
-```bash
-$ npm run hmr
-```
-
-When starting the server Webpack will tell you that it’s enabled:
-
-
-    NOTICE Hot Module Replacement (HMR) is enabled for the dev server.
-
-
-Now if you make changes to one of your components the changes should be visible automatically without a complete browser refresh.

-**Documentation below is for CLI version 6 and we no longer accept PRs to improve this. For version 7 see [here](https://angular.io/guide/testing#set-up-continuous-integration)**.
-
-# Continuous Integration
-
-One of the best ways to keep your project bug free is through a test suite, but it's easy to forget
-to run tests all the time.
-
-That's where Continuous Integration (CI) servers come in.
-You can set up your project repository so that your tests run on every commit and pull request.
-
-There are paid CI services like [Circle CI](https://circleci.com/) and
-[Travis CI](https://travis-ci.com/), and you can also host your own for free using
-[Jenkins](https://jenkins.io/) and others.
-
-Even though Circle CI and Travis CI are paid services, they are provided free for open source
-projects.
-You can create a public project on GitHub and add these services without paying.
-
-We're going to see how to update your test configuration to run in CI environments, and how to
-set up Circle CI and Travis CI.
-
-
-## Update test configuration
-
-Even though `ng test` and `ng e2e` already run on your environment, they need to be adjusted to
-run in CI environments.
-
-We'll use [Headless Chrome](https://developers.google.com/web/updates/2017/04/headless-chrome#cli) in CI environments. In some environments we need to start the browser without
-sandboxing or disable the gpu. Here we'll do both. 
-
-In `karma.conf.js`, add a custom launcher called `ChromeHeadlessCI` below `browsers`:
-
-```
-browsers: ['Chrome'],
-customLaunchers: {
-  ChromeHeadlessCI: {
-    base: 'ChromeHeadless',
-    flags: ['--no-sandbox', '--disable-gpu']
-  }
-},
-```
-
-We'll override the `browsers` option from the command line to use our new configuration.
-
-Create a new file in the `e2e` directory of your project called `protractor-ci.conf.js`, that extends
-the original `protractor.conf.js`:
-
-```
-const config = require('./protractor.conf').config;
-
-config.capabilities = {
-  browserName: 'chrome',
-  chromeOptions: {
-    args: ['--headless', '--no-sandbox', '--disable-gpu']
-  }
-};
-
-exports.config = config;
-```
-
-Now you can run the following commands to use the new configurations:
-
-```
-ng test --watch=false --progress=false --browsers=ChromeHeadlessCI
-ng e2e --protractor-config=./e2e/protractor-ci.conf.js
-```
-
-For CI environments it's also a good idea to disable progress reporting (via `--progress=false`)
-to avoid spamming the server log with progress messages. We've added that option to `ng test`. An equivalent
-option has been requested for
-`ng e2e` [(#11412)](https://github.com/angular/angular-cli/issues/11412). 
-
-
-## Using Circle CI
-
-Create a folder called `.circleci` at the project root, and inside of it create a file called
-`config.yml`:
-
-```yaml
-version: 2
-jobs:
-  build:
-    working_directory: ~/my-project
-    docker:
-      # specify the version you desire here
-      # see https://hub.docker.com/r/circleci/node/tags/
-      - image: circleci/node:8-browsers
-    steps:
-      - checkout
-      - restore_cache:
-          key: my-project-{{ .Branch }}-{{ checksum "package-lock.json" }}
-      - run: npm install
-      - save_cache:
-          key: my-project-{{ .Branch }}-{{ checksum "package-lock.json" }}
-          paths:
-             - "node_modules"
-      - run: npm run test -- --watch=false --progress=false --browsers=ChromeHeadlessCI
-      - run: npm run e2e -- --protractor-config=./e2e/protractor-ci.conf.js
-```
-
-We're doing a few things here:
-  -
-  - `node_modules` is cached.
-  - we use [npm run](https://docs.npmjs.com/cli/run-script) to run `ng` because `@angular/cli` is
-  not installed globally. The double dash (`--`) is needed to pass arguments into the npm script.
-
-Commit your changes and push them to your repository.
-
-Next you'll need to [sign up for Circle CI](https://circleci.com/docs/2.0/first-steps/) and
-[add your project](https://circleci.com/add-projects).
-Your project should start building.
-
-Be sure to check out the [Circle CI docs](https://circleci.com/docs/2.0/) if you want to know more.
-
-
-## Using Travis CI
-
-Create a file called `.travis.yml` at the project root:
-
-```yaml
-dist: trusty
-sudo: false
-
-language: node_js
-node_js:
-  - "8"
-
-addons:
-  apt:
-    sources:
-      - google-chrome
-    packages:
-      - google-chrome-stable
-
-cache:
-  directories:
-     - ./node_modules
-
-install:
-  - npm install
-
-script:
-  - npm run test -- --watch=false --progress=false --browsers=ChromeHeadlessCI
-  - npm run e2e -- --protractor-config=./e2e/protractor-ci.conf.js
-```
-
-Commit your changes and push them to your repository.
-
-Next you'll need to [sign up for Travis CI](https://travis-ci.org/auth) and
-[add your project](https://travis-ci.org/profile).
-You'll need to push a new commit to trigger a build.
-
-Be sure to check out the [Travis CI docs](https://docs.travis-ci.com/) if you want to know more.
-
-## ChromeDriver
-
-In CI environments it's a good idea to to use a specific version of [ChromeDriver](http://chromedriver.chromium.org/)
-instead of allowing `ng e2e` to use the latest one. CI environments often use older versions of chrome, which are unsupported by newer versions of ChromeDriver.
-
-An easy way to do this is to define a NPM script:
-
-```text
-"webdriver-update-ci": "webdriver-manager update --standalone false --gecko false --versions.chrome 2.37"
-```
-
-And then on CI environments you call that script followed by the e2e command without updating webdriver:
-
-```text
-npm run webdriver-update-ci
-ng e2e --webdriver-update=false
-```
-
-This way you will always use a specific version of chrome driver between runs.

-
-# Library support in Angular CLI 6
-
-Angular CLI v6 comes with library support via [ng-packagr](https://github.com/dherges/ng-packagr)
-plugged into the build system we use in Angular CLI, together with schematics for generating a
-library.
-
-
-## Generating a library
-
-You can create a library in a existing workspace by running the following commands:
-
-```
-ng generate library my-lib
-```
-
-You should now have a library inside `projects/my-lib`.
-It contains a component and a service inside a NgModule.
-
-
-## Building your library
-
-You can build this library via `ng build my-lib`, and also unit test it and lint it by replacing
-`build` with `test` or `lint`.
-
-## Using your library inside your apps
-
-Before you use your library, it's important to understand the mental model of how libraries are
-used in general.
-
-When you want to use a library from `npm`, you must:
-
-- install the library into node_modules via `npm install library-name`
-- import it in your application by name `import { something } from 'library-name';`
-
-This works because importing a library in Angular CLI looks for a mapping between library name
-and location on disk.
-
-Angular CLI first looks in your tsconfig paths, then in the node_modules folder.
-
-When you build your own libraries it doesn't go into node_modules so we use the tsconfig paths
-to tell the build system where it is.
-Generating a library automatically adds its path to the tsconfig file.
-
-Using your own library follows a similar pattern:
-
-- build the library via `ng build my-lib`
-- import it in your application by name `import { something } from 'my-lib';`
-
-It's important to note that your app can never use your library before it is built.
-
-For instance, if you clone your git repository and run `npm install`, your editor will show
-the `my-lib` imports as missing.
-This is because you haven't yet built your library.
-
-Another common problem is changes to your library not being reflected in your app.
-This is often because your app is using an old build of your library.
-If this happens just rebuild your library.
-
-
-## Publishing your library
-
-To publish your library follow these steps:
-
-```
-ng build my-lib
-cd dist/my-lib
-npm publish
-```
-
-If you've never published a package in npm before, you will need to create a user account.
-You can read more about publishing on npm here:
-https://docs.npmjs.com/getting-started/publishing-npm-packages
-
-
-## Why do I need to build the library everytime I make changes?
-
-Running `ng build my-lib` every time you change a file is bothersome and takes time.
-In `Angular CLI` version `6.2` an incremental builds functionality has been added to improve the experience of library developers. 
-Everytime a file is changed a partial build is performed that emits the amended files.
-
-The feature can be using by passing `--watch` command argument as show below;
-
-```bash
-ng build my-lib --watch
-```
-
-Note: This feature requires that Angular's Compiler Option [enableResourceInlining](https://angular.io/guide/aot-compiler#enableresourceinlining) is enabled.
-This can be done by adding the below in your `tsconfig.lib.json`.
-
-```javascript
-"angularCompilerOptions": {
-    "enableResourceInlining": true,
-    ...
-}
-```
-
-## Note for upgraded projects
-
-If you are using an upgraded project, there are some additional changes you have to make to support
-monorepo (a workspace with multiple projects) setups:
-
-- in `angular.json`, change the `outputPath` to `dist/project-name` for your app
-- remove `baseUrl` in `src/tsconfig.app.json` and `src/tsconfig.spec.json`
-- add `"baseUrl": "./"` in `./tsconfig.json`
-- change any absolute path imports in your app to be absolute from the root (including `src/`),
-or make them relative
-
-This is necessary to support multiple projects in builds and in your editor.
-New projects come with this configuration by default.

-# CSS Preprocessor integration
-
-Angular CLI supports all major CSS preprocessors:
-- sass/scss ([http://sass-lang.com/](http://sass-lang.com/))
-- less ([http://lesscss.org/](http://lesscss.org/))
-- stylus ([http://stylus-lang.com/](http://stylus-lang.com/))
-
-To use these preprocessors simply add the file to your component's `styleUrls`:
-
-```javascript
-@Component({
-  selector: 'app-root',
-  templateUrl: './app.component.html',
-  styleUrls: ['./app.component.scss']
-})
-export class AppComponent {
-  title = 'app works!';
-}
-```
-
-When generating a new project you can also define which extension you want for
-style files:
-
-```bash
-ng new sassy-project --style=sass
-```
-
-Or set the default style on an existing project:
-
-```bash
-ng config schematics.@schematics/angular:component.styleext scss
-# note: @schematics/angular is the default schematic for the Angular CLI
-```
-
-Style strings added to the `@Component.styles` array _must be written in CSS_ because the CLI cannot apply a pre-processor to inline styles.

-# Serve from Disk
-
-The CLI supports running a live browser reload experience to users by running `ng serve`. This will compile the application upon file saves and reload the browser with the newly compiled application. This is done by hosting the application in memory and serving it via [webpack-dev-server](https://webpack.js.org/guides/development/#webpack-dev-server).
-
-If you wish to get a similar experience with the application output to disk please use the steps below. This practice will allow you to ensure that serving the contents of your `dist` dir will be closer to how your application will behave when it is deployed.
-
-## Environment Setup
-### Install a web server
-You will not be using webpack-dev-server, so you will need to install a web server for the browser to request the application. There are many to choose from but a good one to try is [lite-server](https://github.com/johnpapa/lite-server) as it will auto-reload your browser when new files are output.
-
-## Usage
-You will need two terminals to get the live-reload experience. The first will run the build in a watch mode to compile the application to the `dist` folder. The second will run the web server against the `dist` folder. The combination of these two processes will mimic the same behavior of ng serve.
-
-### 1st terminal - Start the build
-```bash
-ng build --watch
-```
-
-### 2nd terminal - Start the web server
-```bash
-lite-server --baseDir="dist"
-```
-When using `lite-server` the default browser will open to the appropriate URL.

-# Deploy to GitHub Pages
-
-A simple way to deploy your Angular app is to use
-[GitHub Pages](https://help.github.com/articles/what-is-github-pages/).
-
-The first step is to [create a GitHub account](https://github.com/join), and then
-[create a repository](https://help.github.com/articles/create-a-repo/) for your project.
-Make a note of the user name and project name in GitHub.
-
-Then all you need to do is run `ng build --prod --output-path docs --base-href PROJECT_NAME`, where
-`PROJECT_NAME` is the name of your project in GitHub.
-Make a copy of `docs/index.html` and name it `docs/404.html`.
-
-Commit your changes and push. On the GitHub project page, configure it to
-[publish from the docs folder](https://help.github.com/articles/configuring-a-publishing-source-for-github-pages/#publishing-your-github-pages-site-from-a-docs-folder-on-your-master-branch).
-
-And that's all you need to do! Now you can see your page at
-`https://USER_NAME.github.io/PROJECT_NAME/`.
-
-You can also use [angular-cli-ghpages](https://github.com/angular-schule/angular-cli-ghpages), a full
-featured package that does this all this for you and has extra functionality.
-All you need is a single command:
-
-```bash
-ngh --dir=dist/docs
-```
-
-It takes care of pushing to the `gh-pages` branch and copying your `index.html` to `404.html`.

-# Global Library Installation
-
-Some javascript libraries need to be added to the global scope and loaded as if
-they were in a script tag.
-We can do this using the `scripts` and `styles` options of the build target in `angular.json`.
-
-As an example, to use [Bootstrap 4](https://getbootstrap.com/docs/4.0/getting-started/introduction/)
-this is what you need to do:
-
-First install Bootstrap from `npm`:
-
-```bash
-npm install jquery --save
-npm install popper.js --save
-npm install bootstrap --save
-```
-
-Then add the needed script files to `scripts`:
-
-```json
-"scripts": [
-  "node_modules/jquery/dist/jquery.slim.js",
-  "node_modules/popper.js/dist/umd/popper.js",
-  "node_modules/bootstrap/dist/js/bootstrap.js"
-],
-```
-
-Finally add the Bootstrap CSS to the `styles` array:
-```json
-"styles": [
-  "node_modules/bootstrap/dist/css/bootstrap.css",
-  "src/styles.css"
-],
-```
-
-Restart `ng serve` if you're running it, and Bootstrap 4 should be working on your app.

-
-# Global scripts
-
-You can add Javascript files to the global scope via the `scripts` option inside your
-project's build target options in `angular.json`.
-These will be loaded exactly as if you had added them in a `<script>` tag inside `index.html`.
-
-This is especially useful for legacy libraries or analytic snippets.
-
-```json
-"architect": {
-  "build": {
-    "builder": "@angular-devkit/build-angular:browser",
-    "options": {
-      "scripts": [
-        "src/global-script.js",
-      ],
-```
-
-You can also rename the output and lazy load it by using the object format:
-
-```json
-"scripts": [
-  "src/global-script.js",
-  { "input": "src/lazy-script.js", "lazy": true },
-  { "input": "src/pre-rename-script.js", "bundleName": "renamed-script" },
-],
-```
-
-Note: you will also need to add any scripts to the `test` builder if you need them for unit tests.
-
-## Using global libraries inside your app
-
-Once you import a library via the scripts array, you should **not** import it via a import statement
-in your TypeScript code (e.g. `import * as $ from 'jquery';`).
-If you do that you'll end up with two different copies of the library: one imported as a
-global library, and one imported as a module.
-
-This is especially bad for libraries with plugins, like JQuery, because each copy will have
-different plugins.
-
-Instead, download typings for your library (`npm install @types/jquery`) and follow
-the [3rd Party Library Installation](https://github.com/angular/angular-cli/wiki/stories-third-party-lib) steps,
-this will give you access to the global variables exposed by that library.
-
-If the global library you need to use does not have global typings, you can also declare them
-manually in `src/typings.d.ts` as `any`:
-
-```
-declare var libraryName: any;
-```
-
-When working with scripts that extend other libraries, for instance with JQuery plugins
-(e.g, `$('.test').myPlugin();`), since the installed `@types/jquery` may not include `myPlugin`,
-you would need to add an interface like the one below in `src/typings.d.ts`.
-
-```
-interface JQuery {
-  myPlugin(options?: any): any;
-}
-```
-
-Otherwise you may see `[TS][Error] Property 'myPlugin' does not exist on type 'JQuery'.` in your IDE.

-
-# Global styles
-
-The `styles.css` file allows users to add global styles and supports
-[CSS imports](https://developer.mozilla.org/en/docs/Web/CSS/@import).
-
-If the project is created with the `--style=sass` option, this will be a `.sass`
-file instead, and the same applies to `scss/less/styl`.
-
-You can add more global styles via the `styles` option inside your project's build target options
-in `angular.json`.
-These will be loaded exactly as if you had added them in a `<link>` tag inside `index.html`.
-
-```json
-"architect": {
-  "build": {
-    "builder": "@angular-devkit/build-angular:browser",
-    "options": {
-      "styles": [
-        "src/styles.css",
-        "src/more-styles.css",
-      ],
-      ...
-```
-
-You can also rename the output and lazy load it by using the object format:
-
-```json
-"styles": [
-  "src/styles.css",
-  "src/more-styles.css",
-  { "input": "src/lazy-style.scss", "lazy": true },
-  { "input": "src/pre-rename-style.scss", "bundleName": "renamed-style" },
-],
-```
-
-In Sass and Stylus you can also make use of the `includePaths` functionality for both component and
-global styles, which allows you to add extra base paths that will be checked for imports.
-
-To add paths, use the `stylePreprocessorOptions` option:
-
-```
-"stylePreprocessorOptions": {
-  "includePaths": [
-    "src/style-paths"
-  ]
-},
-```
-
-Files in that folder, e.g. `src/style-paths/_variables.scss`, can be imported from anywhere in your
-project without the need for a relative path:
-
-```
-// src/app/app.component.scss
-// A relative path works
-@import 'http://github.com/style-paths/variables';
-// But now this works as well
-@import 'http://github.com/variables';
-```
-
-Note: you will also need to add any styles to the `test` builder if you need them for unit tests.

-</a>
-
-> Above is snapshot of a [Online Demos](https://tburleson-layouts-demos.firebaseapp.com/#/docs) using @angular/flex-layout
-
-
-<br/>
-
-### Include `@angular/flex-layout` as detailed below:
-
-Install the  library and add the dependency to package.json...
-```bash
-npm install --save @angular/flex-layout
-```
-
-Or install the nightly build using:
-
-```bash
-npm i --save @angular/flex-layout-builds
-```
-
-Import the Angular Flex-Layout NgModule into your app module...
-```javascript
-//in src/app/app.module.ts 
-
-import { FlexLayoutModule } from '@angular/flex-layout';
-// other imports 
-
-@NgModule({
-  imports: [
-    ...
-    FlexLayoutModule
-  ],
-  ...
-})
-```
-
-Run `ng serve` to run your application in develop mode, and navigate to `http://localhost:4200`
-
-<br/>
-
-### Sample App
-
-Add the following to `src/app/app.component.css`...
-```css
-[fxLayout="column"] { border: 1px solid;padding:4px; margin-top:50px; },
-[fxFlex]{  padding:5px;},
-h3      {  padding-top:20px; },
-.header {  background-color: lightyellow;  },
-.left   {  background-color: lightblue;  },
-.right  {  background-color: pink;  }
-```
-
-To verify flex-layout has been set up correctly, change `src/app/app.component.html` to the following...
-```html
- <div fxLayout="column">
-   <div class="header" fxLayout="row" fxLayoutAlign="space-between center">
-       <h3>
-         {{title}}
-       </h3>
-   </div>
-   <div fxLayout="row">
-       <div class="left" fxFlex="20"> LEFT: 20% wide </div>
-       <div class="right" fxFlex> RIGHT: 80% wide </div>
-   </div>
- </div>
- ```
-
-After saving this file, return to the browser to see the very ugly but demonstrative flex-layout.
-
-![screen shot 2017-08-05 at 7 20 05 pm](https://user-images.githubusercontent.com/210413/28999629-35c566a0-7a13-11e7-8d36-1d1a2244443c.png)
-
-Among what you should see are - a light yellow header that is the entire width of the window, sitting directly atop 2 columns. Of those 2 columns, the left column should be light blue, and 20% wide, while the right column is pink, 80% to start, and will flex with window (re)size.

-# Include AngularFire
-
-[Firebase](https://firebase.google.com/) is a mobile and web application platform with tools and infrastructure designed
-to help developers build high-quality apps. [AngularFire2](https://github.com/angular/angularfire2) is the official
-Angular library to use Firebase in your apps.
-
-#### Create new project
-
-Create a new project and navigate into the project.
-
-```bash
-$ ng new my-app
-$ cd my-app
-```
-
-#### Install dependencies
-
-In the new project you need to install the required dependencies.
-
-```bash
-$ npm install --save angularfire2 firebase
-```
-
-#### Get Firebase configuration details
-
-In order to connect AngularFire to Firebase you need to get the configuration details.
-
-Firebase offers an easy way to get this, by showing a JavaScript object that you can copy and paste.
-
-- Log in to the [Firebase](https://firebase.google.com) console.
-- Create New Project or open an existing one.
-- Click `Add Firebase to your web app`.
-- From the modal window that pops up you copy the `config` object.
-
-```javascript
-  var config = {
-    apiKey: "your-api-key",
-    authDomain: "your-auth-domain",
-    databaseURL: "your-database-url",
-    storageBucket: "your-storage-bucket",
-    messagingSenderId: "your-message-sender-id"
-  };
-```
-
-#### Configure the Environment
-
-These configuration details need to be stored in our app, one way to do this using the `environment`. This allows you to
-use different credentials in development and production.
-
-Open `src/environments/environment.ts` and add a key `firebase` to the exported constant:
-
-```typescript
-export const environment = {
-  production: false,
-  firebase: {
-    apiKey: 'your-api-key',
-    authDomain: 'your-auth-domain',
-    databaseURL: 'your-database-url',
-    storageBucket: 'your-storage-bucket',
-  }
-};
-```
-
-To define the keys for production you need to update `src/environments/environment.prod.ts`.
-
-#### Import and load FirebaseModule
-
-The final step is to import `AngularFireModule` and initialize it using the parameters from the `environment`.
-
-Open `src/app/app.module.ts` and add the following lines on the top of the file, with the other imports:
-
-```typescript
-import { AngularFireModule } from 'angularfire2';
-import { environment } from '../environments/environment';
-```
-
-To initialize AngularFire add the following line to the `imports` array inside the `NgModule`:
-
-```typescript
-@NgModule({
-  // declarations
-  imports: [
-    // BrowserModule, etc
-    AngularFireModule.initializeApp(environment.firebase),
-  ]
-  // providers
-  // bootstrap
-})
-```
-
-#### Congratulations, you can now use Firebase in your Angular app!

-# Include [Bootstrap](http://getbootstrap.com/)
-
-[Bootstrap](http://getbootstrap.com/) is a popular CSS framework which can be used within an Angular project.
-This guide will walk you through adding bootstrap to your Angular CLI project and configuring it to use bootstrap.
-
-## Using CSS
-
-### Getting Started
-
-Create a new project and navigate into the project
-
-```
-ng new my-app
-cd my-app
-```
-
-### Installing Bootstrap
-
-With the new project created and ready you will next need to install bootstrap to your project as a dependency.
-Using the `--save` option the dependency will be saved in package.json
-
-```sh
-npm install bootstrap --save
-```
-
-### Configuring Project
-
-Now that the project is set up it must be configured to include the bootstrap CSS.
-
-- Open the file `angular.json` from the root of your project.
-- Under the property `projects` find your project.
-- Inside `architect.build.options` locate the `styles` property.
-- This property allows external global styles to be applied to your application.
-- Specify the path to `bootstrap.min.css`
-
-  It should look like the following when you are done:
-  ```json
-  "build": {
-    "options": {
-      "styles": [
-        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
-        "styles.css"
-      ],
-    }
-  }
-  ```
-
-**Note:** When you make changes to `angular.json` you will need to re-start `ng serve` to pick up configuration changes.
-
-### Testing Project
-
-Open `app.component.html` and add the following markup:
-
-```html
-<button class="btn btn-primary">Test Button</button>
-```
-
-With the application configured, run `ng serve` to run your application in develop mode.
-In your browser navigate to the application `localhost:4200`.
-Verify the bootstrap styled button appears.
-
-## Using SASS
-
-### Getting Started
-
-Create a new project and navigate into the project
-
-```
-ng new my-app --style=scss
-cd my-app
-```
-
-### Installing Bootstrap
-
-```sh
-npm install bootstrap --save
-```
-
-### Configuring Project
-
-Create an empty file `_variables.scss` in `src/`.
-
-If you are using `bootstrap-sass`, add the following to `_variables.scss`:
-
-```sass
-$icon-font-path: '../node_modules/bootstrap-sass/assets/fonts/bootstrap/';
-```
-
-In `styles.scss` add the following:
-
-```sass
-@import 'http://github.com/variables';
-@import 'http://github.com/node_modules/bootstrap/scss/bootstrap';
-```
-
-### Testing Project
-
-Open `app.component.html` and add the following markup:
-
-```html
-<button class="btn btn-primary">Test Button</button>
-```
-
-With the application configured, run `ng serve` to run your application in develop mode.
-In your browser navigate to the application `localhost:4200`.
-Verify the bootstrap styled button appears.
-To ensure your variables are used open `_variables.scss` and add the following:
-
-```sass
-$primary: red;
-```
-
-Return the browser to see the font color changed.

-# Include [Font Awesome](https://fontawesome.com/)
-
-[Font Awesome](https://fontawesome.com/) gives you scalable vector icons that can instantly be customized — size, color, drop shadow, and anything that can be done with the power of CSS.
-
-Create a new project and navigate into the project...
-```
-ng new my-app
-cd my-app
-```
-
-Install the `font-awesome` library and add the dependency to package.json...
-```bash

-**Documentation below is for CLI version 6 and we no longer accept PRs to improve this. For version 7 see [here](https://angular.io/guide/i18n)**.
-
-# Internationalization (i18n)
-
-If you are working on internationalization, the CLI can help you with the following steps:
-- extraction
-- serve
-- build
-
-The first thing that you have to do is to setup your application to use i18n.
-To do that you can follow [the cookbook on angular.io](https://angular.io/guide/i18n).
-
-### Extraction
-When your app is ready, you can extract the strings to translate from your templates with the
-`ng xi18n` command.
-
-By default it will create a file named `messages.xlf` in your `src` folder.
-You can use [parameters from the xi18n command](./xi18n) to change the format,
-the name, the location and the source locale of the extracted file.
-
-For example to create a file in the `src/locale` folder you would use:
-```sh
-ng xi18n --output-path src/locale
-```
-
-### Building and serving
-Now that you have generated a messages bundle source file, you can translate it.
-Let's say that your file containing the french translations is named `messages.fr.xlf`
-and is located in the `src/locale` folder.
-
-If you want to use it when you serve your application you can use the 4 following options:
-- `i18nFile` Localization file to use for i18n.
-- `i18nFormat` Format of the localization file specified with --i18n-file.
-- `i18nLocale` Locale to use for i18n.
-- `i18nMissingTranslation` Defines the strategy to use for missing i18n translations.
-
-In our case we can load the french translations with the following configuration:
-```json
-"architect": {
-  "build": {
-    "builder": "@angular-devkit/build-angular:browser",
-    "options": { ... },
-    "configurations": {
-      "fr": {
-        "aot": true,
-        "outputPath": "dist/my-project-fr/",
-        "i18nFile": "src/locale/messages.fr.xlf",
-        "i18nFormat": "xlf",
-        "i18nLocale": "fr",
-        "i18nMissingTranslation": "error",
-      }
-// ...
-"serve": {
-  "builder": "@angular-devkit/build-angular:dev-server",
-  "options": {
-    "browserTarget": "your-project-name:build"
-  },
-  "configurations": {
-    "production": {
-      "browserTarget": "your-project-name:build:production"
-    },
-    "fr": {
-      "browserTarget": "your-project-name:build:fr"
-    }
-  }
-},
-```
-
-To build the application using the French i18n options, use `ng build --configuration=fr`.
-To serve, use `ng serve --configuration=fr`.
-
-Our application is exactly the same but the `LOCALE_ID` has been provided with "fr",
-`TRANSLATIONS_FORMAT` with "xlf" and `TRANSLATIONS` with the content of `messages.fr.xlf`.
-All the strings flagged for i18n have been replaced with their french translations.
-
-Note: this only works for AOT, if you want to use i18n in JIT you will have to update
-your bootstrap file yourself.
-
-### Using multiple languages
-
-When you build your application for a specific locale, it is probably a good idea to change
-the output path with the `outputPath` options in order to save the files to a different location.
-
-If you end up serving this specific version from a subdirectory, you can also change
-the base url used by your application with the `baseHref` option.
-
-For example if the french version of your application is served from https://myapp.com/fr/
-then you would build the french version like this:
-
-```json
-"configurations": {
-  "fr": {
-    "aot": true,
-    "outputPath": "dist/my-project-fr/",
-    "baseHref": "/fr/",
-    "i18nFile": "src/locale/messages.fr.xlf",

-# Multiple Projects
-
-Angular CLI supports multiple applications within one workspace.
-
-To create another app you can use the following command:
-```sh
-ng generate application my-other-app
-```
-
-The new application will be generated inside `projects/my-other-app`.
-
-Now we can `serve`, `build` etc. both the apps by passing the project name with the commands:
-
-```sh
-ng serve my-other-app
-```
-
-You can also create libraries, which is detailed in [Create a library](stories/create-library).

-**Documentation below is for CLI version 6 and we no longer accept PRs to improve this. For version 7 see [here](https://angular.io/guide/build#using-corporate-proxy)**.
-
-# Proxy To Backend
-
-Using the [proxying support](https://webpack.js.org/configuration/dev-server/#devserver-proxy) in webpack's dev server we can highjack certain URLs and send them to a backend server.
-We do this by passing a file to `--proxy-config`
-
-Say we have a server running on `http://localhost:3000/api` and we want all calls to `http://localhost:4200/api` to go to that server.
-
-We create a file next to our project's `package.json` called `proxy.conf.json` with the content
-
-```json
-{
-  "/api": {
-    "target": "http://localhost:3000/",
-    "secure": false
-  }
-}
-```
-
-You can read more about what options are available [here](https://webpack.js.org/configuration/dev-server/#devserver-proxy).
-
-We can then add the `proxyConfig` option to the serve target:
-
-```json
-"architect": {
-  "serve": {
-    "builder": "@angular-devkit/build-angular:dev-server",
-    "options": {
-      "browserTarget": "your-application-name:build",
-      "proxyConfig": "proxy.conf.json"
-    },
-```
-
-Now in order to run our dev server with our proxy config we can call `ng serve`.
-
-**After each edit to the proxy.conf.json file remember to relaunch the `ng serve` process to make your changes effective.**
-
-### Rewriting the URL path
-
-One option that comes up a lot is rewriting the URL path for the proxy. This is supported by the `pathRewrite` option.
-
-Say we have a server running on `http://localhost:3000` and we want all calls to `http://localhost:4200/api` to go to that server.
-
-In our `proxy.conf.json` file, we add the following content
-
-```json
-{
-  "/api": {
-    "target": "http://localhost:3000/",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    }
-  }
-}
-```
-
-If you need to access a backend that is not on localhost, you will need to add the `changeOrigin` option as follows:
-
-```json
-{
-  "/api": {
-    "target": "http://npmjs.org/",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    },
-    "changeOrigin": true
-  }
-}
-```
-
-To help debug whether or not your proxy is working properly, you can also add the `logLevel` option as follows:
-
-```json
-{
-  "/api": {
-    "target": "http://localhost:3000/",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    },
-    "logLevel": "debug"
-  }
-}
-```
-
-Possible options for `logLevel` include `debug`, `info`, `warn`, `error`, and `silent` (default is `info`)
-
-
-### Multiple entries
-
-If you need to proxy multiple entries to the same target define the configuration in `proxy.conf.js` instead of `proxy.conf.json` e.g.
-
-```js
-const PROXY_CONFIG = [
-    {
-        context: [
-            "/my",
-            "/many",
-            "/endpoints",
-            "/i",
-            "/need",
-            "/to",
-            "/proxy"
-        ],
-        target: "http://localhost:3000/",
-        secure: false
-    }
-]
-
-module.exports = PROXY_CONFIG;
-```
-
-Make sure to point to the right file (`.js` instead of `.json`):
-
-```json
-"architect": {
-  "serve": {
-    "builder": "@angular-devkit/build-angular:dev-server",
-    "options": {
-      "browserTarget": "your-application-name:build",
-      "proxyConfig": "proxy.conf.js"
-    },
-```
-
-### Bypass the Proxy
-
-If you need to optionally bypass the proxy, or dynamically change the request before it's sent,  define the configuration in proxy.conf.js e.g.
-
-```js
-const PROXY_CONFIG = {
-    "/api/proxy": {
-        "target": "http://localhost:3000/",
-        "secure": false,
-        "bypass": function (req, res, proxyOptions) {
-            if (req.headers.accept.indexOf("html") !== -1) {
-                console.log("Skipping proxy for browser request.");
-                return "/index.html";
-            }
-            req.headers["X-Custom-Header"] = "yes";
-        }
-    }
-}
-
-module.exports = PROXY_CONFIG;
-```
-
-### Using corporate proxy
-
-If you work behind a corporate proxy, the regular configuration will not work if you try to proxy
-calls to any URL outside your local network.
-
-In this case, you can configure the backend proxy to redirect calls through your corporate
-proxy using an agent:
-
-```bash
-npm install --save-dev https-proxy-agent
-```
-
-Then instead of using a `proxy.conf.json` file, we create a file called `proxy.conf.js` with
-the following content:
-
-```js
-var HttpsProxyAgent = require('https-proxy-agent');
-var proxyConfig = [{
-  context: '/api',
-  target: 'http://your-remote-server.com:3000/',
-  secure: false
-}];
-
-function setupForCorporateProxy(proxyConfig) {
-  var proxyServer = process.env.http_proxy || process.env.HTTP_PROXY;
-  if (proxyServer) {
-    var agent = new HttpsProxyAgent(proxyServer);
-    console.log('Using corporate proxy server: ' + proxyServer);
-    proxyConfig.forEach(function(entry) {
-      entry.agent = agent;
-    });
-  }
-  return proxyConfig;
-}
-
-module.exports = setupForCorporateProxy(proxyConfig);
-```
-
-This way if you have a `http_proxy` or `HTTP_PROXY` environment variable defined, an agent will automatically be added to pass calls through your corporate proxy when running `npm start`.

-# 3rd Party Library Installation
-
-Simply install your library via `npm install lib-name --save` and import it in your code.
-
-If the library does not include typings, you can install them using npm:
-
-```bash
-npm install d3 --save
-npm install @types/d3 --save-dev
-```
-
-Then open `src/tsconfig.app.json` and add it to the `types` array:
-
-```
-"types":[
-  "d3"
-]
-```
-
-If the library you added typings for is only to be used on your e2e tests,
-instead use `e2e/tsconfig.e2e.json`.
-The same goes for unit tests and `src/tsconfig.spec.json`.
-
-If the library doesn't have typings available at `@types/`, you can still use it by
-manually adding typings for it:
-
-1. First, create a `typings.d.ts` file in your `src/` folder. This file will be automatically included as global type definition.
-
-2. Then, in `src/typings.d.ts`, add the following code:
-
-  ```typescript
-  declare module 'typeless-package';
-  ```
-
-3. Finally, in the component or file that uses the library, add the following code:
-
-  ```typescript
-  import * as typelessPackage from 'typeless-package';
-  typelessPackage.method();
-  ```
-
-Done. Note: you might need or find useful to define more typings for the library that you're trying to use.

-
-# Angular Universal Integration
-
-The Angular CLI supports generation of a Universal build for your application. This is a CommonJS-formatted bundle which can be `require()`'d into a Node application (for example, an Express server) and used with `@angular/platform-server`'s APIs to prerender your application.
-
----
-
-## Example CLI Integration:
-
-[Angular Universal-Starter](https://github.com/angular/universal-starter) - Clone the universal-starter for a working example.
-
----
-
-# Integrating Angular Universal into existing CLI Applications
-
-This story will show you how to set up Universal bundling for an existing `@angular/cli` project in 5 steps.
-
----
-
-## Install Dependencies
-
-Install `@angular/platform-server` into your project. Make sure you use the same version as the other `@angular` packages in your project.
-
-> You'll also need @nguniversal/module-map-ngfactory-loader, as it's used to handle lazy-loading in the context of a server-render. (by loading the chunks right away)
-
-```bash
-$ npm install --save @angular/platform-server @nguniversal/module-map-ngfactory-loader express
-```
-
-## Step 1: Prepare your App for Universal rendering
-
-The first thing you need to do is make your `AppModule` compatible with Universal by adding `.withServerTransition()` and an application ID to your `BrowserModule` import:
-
-
-### src/app/app.module.ts:
-
-```typescript
-@NgModule({
-  bootstrap: [AppComponent],
-  imports: [
-    // Add .withServerTransition() to support Universal rendering.
-    // The application ID can be any identifier which is unique on
-    // the page.
-    BrowserModule.withServerTransition({appId: 'my-app'}),
-    ...
-  ],
-
-})
-export class AppModule {}
-```
-
-Next, create a module specifically for your application when running on the server. It's recommended to call this module `AppServerModule`.
-
-This example places it alongside `app.module.ts` in a file named `app.server.module.ts`:
-
-
-### src/app/app.server.module.ts:
-
-You can see here we're simply Importing everything from AppModule, followed by ServerModule.
-
-> One important thing to Note: We need `ModuleMapLoaderModule` to help make Lazy-loaded routes possible during Server-side renders with the Angular CLI.
-
-```typescript
-import {NgModule} from '@angular/core';
-import {ServerModule} from '@angular/platform-server';
-import {ModuleMapLoaderModule} from '@nguniversal/module-map-ngfactory-loader';
-
-import {AppModule} from './app.module';
-import {AppComponent} from './app.component';
-
-@NgModule({
-  imports: [
-    // The AppServerModule should import your AppModule followed
-    // by the ServerModule from @angular/platform-server.
-    AppModule,
-    ServerModule,
-    ModuleMapLoaderModule // <-- *Important* to have lazy-loaded routes work
-  ],
-  // Since the bootstrapped component is not inherited from your
-  // imported AppModule, it needs to be repeated here.
-  bootstrap: [AppComponent],
-})
-export class AppServerModule {}
-```
-
----
-## Step 2: Create a server "main" file and tsconfig to build it
-
-Create a main file for your Universal bundle. This file only needs to export your `AppServerModule`. It can go in `src`. This example calls this file `main.server.ts`:
-
-### src/main.server.ts:
-
-```typescript
-export { AppServerModule } from './app/app.server.module';
-```
-
-Copy `tsconfig.app.json` to `tsconfig.server.json` and change it to build with a `"module"` target of `"commonjs"`.
-
-Add a section for `"angularCompilerOptions"` and set `"entryModule"` to your `AppServerModule`, specified as a path to the import with a hash (`#`) containing the symbol name. In this example, this would be `app/app.server.module#AppServerModule`.
-
-### src/tsconfig.server.json:
-
-```javascript
-{
-  "extends": "../tsconfig.json",
-  "compilerOptions": {
-    "outDir": "../out-tsc/app",
-    "baseUrl": "./",
-    // Set the module format to "commonjs":
-    "module": "commonjs",
-    "types": []
-  },
-  "exclude": [
-    "test.ts",
-    "**/*.spec.ts"
-  ],
-  // Add "angularCompilerOptions" with the AppServerModule you wrote
-  // set as the "entryModule".
-  "angularCompilerOptions": {
-    "entryModule": "app/app.server.module#AppServerModule"
-  }
-}
-```
-
----
-## Step 3: Create a new target in `angular.json`
-
-In `angular.json` locate the `architect` property inside your project, and add a new `server`
-target:
-
-```javascript
-"architect": {
-  "build": { ... }
-  "server": {
-    "builder": "@angular-devkit/build-angular:server",
-    "options": {
-      "outputPath": "dist/your-project-name-server",
-      "main": "src/main.server.ts",
-      "tsConfig": "src/tsconfig.server.json"
-    }
-  }
-}
-```
-
-## Building the bundle
-
-With these steps complete, you should be able to build a server bundle for your application, using your project name and command name from `angular.json` to tell the CLI to build the server bundle.
-
-```bash
-# This builds your project using the server target, and places the output
-# in dist/your-project-name-server/
-$ ng run your-project-name:server
-
-Date: 2017-07-24T22:42:09.739Z
-Hash: 9cac7d8e9434007fd8da
-Time: 4933ms
-chunk {0} main.js (main) 9.49 kB [entry] [rendered]
-chunk {1} styles.css (styles) 0 bytes [entry] [rendered]
-```
-
----
-
-
-## Step 4: Setting up an Express Server to run our Universal bundles
-
-Now that we have everything set up to -make- the bundles, how we get everything running?
-
-PlatformServer offers a method called `renderModuleFactory()` that we can use to pass in our AoT'd AppServerModule, to serialize our application, and then we'll be returning that result to the Browser.
-
-```typescript
-app.engine('html', (_, options, callback) => {
-  renderModuleFactory(AppServerModuleNgFactory, {
-    // Our index.html
-    document: template,
-    url: options.req.url,
-    // DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
-    extraProviders: [
-      provideModuleMap(LAZY_MODULE_MAP)
-    ]
-  }).then(html => {
-    callback(null, html);
-  });
-});
-```
-
-You could do this, if you want complete flexibility, or use an express-engine with a few other built in features from [`@nguniversal/express-engine`](https://github.com/angular/universal/tree/master/modules/express-engine) found here.
-
-```typescript
-// It's used as easily as
-import { ngExpressEngine } from '@nguniversal/express-engine';
-
-app.engine('html', ngExpressEngine({
-  bootstrap: AppServerModuleNgFactory,
-  providers: [
-    provideModuleMap(LAZY_MODULE_MAP)
-  ]
-}));
-```
-
-In case you want to use an AppShell with SSR and Lazy loaded modules you need to configure `NgModuleFactoryLoader` as a provider.
-
-For more context see: https://github.com/angular/angular-cli/issues/9202
-
-```typescript
-import { Compiler, NgModuleFactoryLoader } from '@angular/core';
-import { provideModuleMap, ModuleMapNgFactoryLoader, MODULE_MAP } from '@nguniversal/module-map-ngfactory-loader';
-
-app.engine('html', ngExpressEngine({
-  bootstrap: AppServerModuleNgFactory,
-  providers: [
-    provideModuleMap(LAZY_MODULE_MAP),
-    {
-      provide: NgModuleFactoryLoader,
-      useClass: ModuleMapNgFactoryLoader,
-      deps: [
-        Compiler,
-        MODULE_MAP
-      ],
-    },
-  ]
-}));
-```
-
-Below we can see a TypeScript implementation of a -very- simple Express server to fire everything up.
-
-> Note: This is a very bare bones Express application, and is just for demonstrations sake. In a real production environment, you'd want to make sure you have other authentication and security things setup here as well. This is just meant just to show the specific things needed that are relevant to Universal itself. The rest is up to you!
-
-At the ROOT level of your project (where package.json / etc are), created a file named: **`server.ts`**
-
-### ./server.ts (root project level)
-
-```typescript
-// These are important and needed before anything else
-import 'zone.js/dist/zone-node';
-import 'reflect-metadata';
-
-import { renderModuleFactory } from '@angular/platform-server';
-import { enableProdMode } from '@angular/core';
-
-import * as express from 'express';
-import { join } from 'path';
-import { readFileSync } from 'fs';
-
-// Import module map for lazy loading
-import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';
-
-// Faster server renders w/ Prod mode (dev mode never needed)
-enableProdMode();
-
-// Express server
-const app = express();
-
-const PORT = process.env.PORT || 4000;
-const DIST_FOLDER = join(process.cwd(), 'dist');
-
-// Our index.html we'll use as our template
-const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();
-
-app.engine('html', (_, options, callback) => {
-  renderModuleFactory(AppServerModuleNgFactory, {
-    // Our index.html
-    document: template,
-    url: options.req.url,
-    // DI so that we can get lazy-loading to work differently (since we need it to just instantly render it)
-    extraProviders: [
-      provideModuleMap(LAZY_MODULE_MAP)
-    ]
-  }).then(html => {
-    callback(null, html);
-  });
-});
-
-app.set('view engine', 'html');
-app.set('views', join(DIST_FOLDER, 'browser'));
-
-// Server static files from /browser
-app.get('*.*', express.static(join(DIST_FOLDER, 'browser')));
-
-// All regular routes use the Universal engine
-app.get('*', (req, res) => {
-  res.render(join(DIST_FOLDER, 'browser', 'index.html'), { req });
-});
-
-// Start up the Node server
-app.listen(PORT, () => {
-  console.log(`Node server listening on http://localhost:${PORT}`);
-});
-```
-
-## Step 5: Setup a TypeScript config to handle this Node server.ts file and serve your application!
-
-Now that we have our Node Express server setup, we need to pack it and serve it!
-
-Create a file named `server.tsconfig.json` at the ROOT of your application.
-
-> This file basically takes that server.ts file, and takes it and compiles it and every dependency it has into `dist/server.js`.
-
-### ./server.tsconfig.json (root project level)
-
-```typescript
-{
-  "compileOnSave": false,
-  "compilerOptions": {
-    "outDir": "./dist",
-    "sourceMap": true,
-    "declaration": false,
-    "moduleResolution": "node",
-    "emitDecoratorMetadata": true,
-    "experimentalDecorators": true,
-    "target": "es5",
-    "typeRoots": [
-      "node_modules/@types"
-    ],
-    "lib": [
-      "es2017",
-      "dom"
-    ]
-  },
-  "include": ["server.ts"]
-}
-```
-
-**Almost there!**
-
-Now let's see what our resulting structure should look like, if we open up our `/dist/` folder we should see:
-
-```
-/dist/
-   /browser/
-   /server/
-```
-
-To fire up the application, in your terminal enter
-
-```bash
-node dist/server.js
-```
-
-:sparkles:
-
-Now lets create a few handy scripts to help us do all of this in the future.
-
-```json
-"scripts": {
-  // These will be your common scripts
-  "build:ssr": "npm run build:client-and-server-bundles && npm run compile:server",
-  "serve:ssr": "node dist/server.js",
-
-  // Helpers for the above scripts
-  "build:client-and-server-bundles": "ng build --prod && ng run your-project-name:server",
-  "compile:server": "tsc -p server.tsconfig.json",
-}
-```
-
-In the future when you want to see a Production build of your app with Universal (locally), you can simply run:
-
-```bash
-npm run build:ssr && npm run serve:ssr
-```
-
-Enjoy!
-
-Once again to see a working version of everything, check out the [universal-starter](https://github.com/angular/universal-starter).

 they will be able to install all dependencies correctly without Bazel. It is the
 responsibility of the developer to keep both `package.json` in sync.
 
-## Issues
+## Windows support
 
-1. Yarn workspaces is not compatible with Bazel-managed deps
-   [(#12736)](https://github.com/angular/angular-cli/issues/12736)
+In general, any sort of node file lookup on Bazel should be subject to `require.resolve`.
+This is how rules_nodejs resolves paths using the Bazel runfiles mechanism, where a given
+Bazel target only has access to outputs from its dependencies.
 
+In practice, this does not make a lot of difference on Linux.
+A symlink forest is laid down where the target is going to actually run, and mostly the
+files are resolved correctly whether you use `require.resolve` or not because the files are there.
+
+On Windows though, that's a stricter. Bazel does not lay down a symlink forest on
+windows by default. If you don't use `require.resolve`, it's still possible to correctly
+resolve some files, like outputs from other rules. But other files, like node modules
+dependencies and data files, need to be looked up in the runfiles.
+
+Since the requirement is quite lax on Linux but quite strict on windows, what ends up
+happening is that lack of `require.resolve` calls go unnoticed until someone tries to run
+things on Windows, at which point it breaks.
+
+## Debugging jasmine_node_test
+
+On Linux, Bazel tests will run under a sandbox for isolation.
+You can turn off this sandbox by adding the [`local = True`](https://docs.bazel.build/versions/master/be/common-definitions.html#common-attributes-tests) attribute to the rule.
+You can also force local execution by passing `--test_output=streamed`.
+
+Then you will find the intermediate test files in `bazel-out/k8-fastbuild/bin`, followed by the test target path.
+
+Tests that are sharded, via the `shard_count` attribute, can fail if you reduce the number of tests or focus only a few.
+This will cause some shards to execute 0 tests, which makes the exit with an error code.
+
+Tests that are marked as flaky, via the `flaky` attribute, will repeat when they fail.
+This will cause any focused test to be repeated multiple time, since the presence of focused tests
+causes jasmine to exit with a non-zero exit code.
+
+While testing, you can remove the `shard_count` attribute to prevent sharding and the `flaky`
+attribute to prevent repetition.
+Setting `--test_output=streamed` will disable sharding and `--flaky_test_attempts=1` will disable
+the reruns of tests that have been marked as `flaky`.
+
+The `.bazelrc` includes a config for running tests with remote debugging enabled:
+
+```sh
+pnpm bazel test --config=debug //packages/angular/cli:angular-cli_test
+# Also disable reruns of failing tests that were marked as flaky:
+pnpm bazel test --config=debug --config=no-sharding //packages/angular/cli:angular-cli_test
+```

-
-## Triaging Issues
-TBD
-
-## Merging PRs
-
-The list of PRs which are currently ready to merge (approved with passing status checks) can
-be found with [this search](https://github.com/angular/angular-cli/pulls?q=is%3Apr+is%3Aopen+label%3A%22PR+action%3A+merge%22).
-This list should be checked daily and any ready PRs should be merged. For each
-PR, check the `PR target` label to understand where it should be merged to. If
-`master` is targetted, then click "Rebase and Merge". If the PR also targets a
-patch branch, see [Maintaining Patch Branches](#maintaining-patch-branches).
-Whatever the target, rebasing should be used over merging to avoid cluttering
-the Git history with merge commits.
-
-### Maintaining Patch Branches
-
-When a PR is merged, if the `PR target` label includes a branch other than
-`master`, commits will need to be cherry-picked to an associated branch. In
-particular, the `patch` target simply refers to the latest patch branch (eg.
-`1.2.x` or `1.3.x-rc.0`). This branch should be updated by cherry-picking all
-_applicable_ commits to it, such as those with messages beginning with `fix()`,
-`docs()`, or `refactor()`.
-
-Say the following PR is merged;
-
-```text
-* fix(@angular/cli): fix path when doing stuff
-* refactor(@angular-devkit/core): replace Fizz with Buzz
-* feat(@angular-devkit/core): add new feature
-* fix(@angular-devkit/core): fix something related to new feature
-* refactor(@angular-devkit/core): move stuff to new feature
+```bash
+$ git remote add upstream https://github.com/angular/angular-cli.git
 ```
 
-Only the first 2 commits should be cherry picked to the patch branch, as the last 3 are related to a new feature.
-
-Cherry picking is done by checking out the patch branch and cherry picking the new commit onto it.
-The patch branch is simply named as a version number, with a X in the relevant spot, such as `9.0.x`.
-This should be done after merging to master.
+# Caretaker
 
-```shell
-# Make sure commit to upstream/master is present in local repo.
-git fetch upstream master
+The caretaker should triage issues, merge PR, and sheppard the release.
 
-# Check out patch branch from upstream.
-git fetch upstream <patch branch>
-git checkout <patch branch>
+Caretaker rotation can be found

-# Cherry pick the commit. Use the hash from the commit which was merged
-# into upstream/master, which should be known to your local repo.

-# If you have multiple cherry picks, you can do them all here.
+The primary caretaker is responsible for both merging PRs and performing the weekly release.
+The secondary caretaker does not have any _direct_ responsibilities, but they may need to take
+over the primary's responsibilities if the primary is unavailable for an extended time (a day
+or more) or in the event of an emergency.
 
-# Resolve merge conflicts if necessary...
-# Or abort and ask author to submit a separate commit targeting patch-only.
+At the end of each caretaker's rotation, the primary should perform a handoff in which they
+provide information to the next caretaker about the current state of the repository and update
+the access group to now include the next caretakers. To perform this update to the access group,
+the caretaker can run:
 
-# Push changes.
-git push upstream <patch branch>
+```bash
+$ pnpm ng-dev caretaker handoff
 ```
 
-If you get a `bad revision` error when cherry picking, make sure you are using
-the commit hash used when merged into `master`, _not_ the hash listed in the PR.
-Also verify that you have fetched `master` from `upstream` since that commit was
-merged.
-
-If the commit is not merged to `master` (because it targets `patch only` for
-instance), then you will need to fetch the contributor's branch for your local
-Git instance to have knowledge of the commit being cherry picked onto the patch
-branch.

-# Release
-
-## Before releasing
-
-Make sure the CI is green.
-
-Consider if you need to update `packages/schematics/angular/utility/latest-versions.ts` to reflect changes in dependent versions.
-
-## Shepparding
+## Merging PRs
 
-As commits are cherry-picked when PRs are merged, creating the release should be a matter of creating a tag.
+The list of PRs which are currently ready to merge (approved with passing status checks) can
+be found with [this search](https://github.com/angular/angular-cli/pulls?q=is%3Apr+is%3Aopen+label%3A%22action%3A+merge%22+-is%3Adraft).
+This list should be checked daily and any ready PRs should be merged. For each PR, check the
+`target` label to understand where it should be merged to. You can find which branches a specific
+PR will be merged into with the `pnpm ng-dev pr check-target-branches <pr>` command.
 
-**Make sure you update the package versions in `packages/schematics/angular/utility/latest-versions.ts`.**
+When ready to merge a PR, run the following command:
 
 ```bash
-git commit -a -m 'release: vXX'
-git tag 'vXX'
-git push upstream && git push upstream --tags
+pnpm ng-dev pr merge <pr>
 ```
 
-### Authenticating
-
-**This can ONLY be done by a Google employee.**
+### Maintaining LTS branches
 
-Log in to [NPM](https://npmjs.com/) to the `angular` account in order to
-publish. This account is protected by two factor authentication (2FA).
+Releases that are under Long Term Support (LTS) are listed on [angular.dev](https://angular.dev/reference/releases#support-policy-and-schedule).
 
-Run `npm login`:
+Since there could be more than one LTS branch at any one time, PR authors who want to
+merge commits into LTS branches must open a pull request against the specific base branch they'd like to target.
 
-1. For username, use `angular`.
-1. For password, use the value stored [here](http://go/ng-npm-pass).
-1. For email, use `devops+npm@angular.io`.
-1. For two-factor code, you'll need to set up the account.
-    * Use an authenticator app such as [Google Authenticator](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2).
-    * Add a new account and enter the text key from [here](http://go/ng-npm-2fa).
-    * The app will start showing two-factor codes, enter one into the
-        `npm login` prompt.
+In general, cherry picks for LTS should only be done if it meets one of the criteria below:
 
-Once sucessfully logged in, it is time to publish.
+1. It addresses a critical security vulnerability.
+2. It fixes a breaking change in the external environment.
+   For example, this could happen if one of the dependencies is deleted from NPM.
+3. It fixes a legitimate failure on CI for a particular LTS branch.
 
-### Publishing
-
-**This can ONLY be done by a Google employee.**
-
-**It is a good idea to wait for CI to be green on the patch branch and tag before doing the release.**
-
-Check out the patch tag (e.g. `v6.7.8`), then run:
-```sh
-devkit-admin publish
-```
+# Release
 
-Check out the minor tag (e.g. `v6.8.0-beta.0`), then run:
-```bash
-devkit-admin publish --tag next
-```
+Releasing is performed using Angular's unified release tooling. Each week, two releases are expected, `latest` and `next` on npm.
 
-### Release Notes
+**DURING a minor OR major CLI release:**
 
-`devkit-admin changelog` takes `from` and `to` arguments which are any valid git
-ref.
+Once FW releases the actual minor/major release (for example: `13.0.0` or `13.1.0`), update dependencies with the following:
 
-For example, running the following command will output the release notes on
-stdout between v1.2.3 and 1.2.4:
+1.  Update [`constants.bzl`](../../constants.bzl) so `@angular/core` and `ng-packagr` are using the release version (drop `-next.0`).
 
-```bash
-devkit-admin changelog --from=v1.2.3 --to=v1.2.4
-```
+Merge the above change in a separate PR which lands _after_ FW releases (or else CI will fail) but _before_ the CLI
+release PR. Releases are built before the PR is sent for review, so any changes after that point won't be included in the release.
 
-Copy the output (you can use `| pbcopy` on MacOS or `|xclip` on Linux) and
-paste the release notes on [GitHub](https://github.com/angular/angular-cli/releases)
-for the tag just released.
+**AFTER a minor OR major CLI release:**
 
-If you have an API token for GitHub you can create a draft automatically by
-using the `--githubToken` flag. You just then have to confirm the draft.
+`constants.bzl` also needs to be updated to use `-next.0` after a major or minor release. However this needs to happen _after_ FW
+publishes the initial `-next.0` release, which will happen 1 week after the major or minor release.
 
-> **Tags containing `beta` or `rc` should be marked as pre-release.**
+## Releasing the CLI
 
-### Microsite Publishing
+Typical patch and next releases do not require FW to release in advance, as CLI does not pin the FW
+dependency.
 
-The [microsite](https://cli.angular.io/) is the landing page for Angular CLI and
-is a one-page static page.
-
-> **This can ONLY be done by a Google employee.**
->
-> **You will need firebase access to our cli-angular-io firebase site. If you don't have it, escalate.**
-
-Check out if changes were made to the microsite:
+After confirming that the above steps have been done or are not necessary, run the following and
+navigate the prompts:
 
 ```sh
-git log v8.0.0-beta.0..HEAD --oneline etc/cli.angular.io | wc -l
+pnpm ng-dev release publish
 ```
 
-If the number is 0 you can ignore the rest of this section.
-
-To publish, go to the
-[`angular-cli/etc/cli.angular.io`](https://github.com/angular/angular-cli/tree/master/etc/cli.angular.io)
-directory and run `firebase deploy`. You might have to `firebase login` first.
-If you don't have the firebase CLI installed, you can install it using
-`npm install --global firebase-tools` (or use your package manager of choice).
-
-This is detailed in [`etc/cli.angular.io/README.md`](https://github.com/angular/angular-cli/blob/master/etc/cli.angular.io/README.md).
+Releases should be done in "reverse semver order", meaning they should follow:
+
+Oldest LTS -> Newest LTS -> Patch -> RC -> Next
+
+This can skip any versions which don't need releases, so most weeks are just "Patch -> Next".
+
+## Releasing a new package
+
+Wombat has some special access requirements which need to be configured to publish a new NPM package.
+
+See [this Wombat doc](http://g3doc/company/teams/cloud-client-libraries/team/automation/docs/npm-publish-service#existing-package)
+and [this postmortem](http://docs/document/d/1emx2mhvF5xMzNUlDrVRYKI_u4iUOnVrg3rV6c5jk2is?resourcekey=0-qpsFbBfwioYT4f6kyUm8ZA&tab=t.0)
+for more info.
+
+Angular is _not_ an organization on NPM, therefore each package is published
+independently and Wombat access needs to be managed individually. This also means
+we can't rely on Wombat already having access to a new package.
+
+In order to configure a brand new NPM package, it first needs to be published
+manually so we can add Wombat access to it. Note that this step can and should be
+done prior to weekly releases. The sooner this can be done, the less likely it
+will block the next weekly release.
+
+1.  Check out the `main` branch, which should always have a `-next` version.
+    - This avoids having the initial publish actually be used in production.
+1.  Trigger a release build locally.
+    ```shell
+    nvm install
+    pnpm install --frozen-lockfile
+    pnpm ng-dev release build
+    ```
+1.  Log in to NPM as `angular`.
+    ```shell
+    npm login

+
+## Updating Browser Support
+
+Angular's browser support is defined by a [Baseline](https://web.dev/baseline)
+"widely available" date. Before a new major version is released, this should be
+updated to approximately the current date.
+
+A few weeks before a major (around feature freeze):
+
+1.  Update `BASELINE_DATE` in
+    [`/constants.bzl`](/constants.bzl) to the end of the most recent month.
+    - For example, if it is currently May 12th, set `baselineThreshold` to April
+      30th.
+    - Picking a date at the end of a month makes it easier to cross-reference
+      Angular's support with other tools (like MDN) which state Baseline support
+      using month specificity.
+    - You can view the generated `browserlist` configuration with:
+      ```shell
+      bazel build //packages/angular/build:angular_browserslist
+      cat dist/bin/packages/angular/build/.browserslistrc
+      ```
+    - Commit and merge the change, no other alterations or automation is
+      necessary in the CLI repo.
+2.  Update
+    [`/.browserslistrc`](https://github.com/ng-packagr/ng-packagr/tree/main/.browserslistrc)
+    in the `ng-packagr` repo.
+    - Use the generated configuration from above.
+3.  Update
+    [`angular.dev` documentation](https://github.com/angular/angular/tree/main/adev/src/content/reference/versions.md#browser-support)
+    to specify the date used and link to [browsersl.ist](https://browsersl.ist)
+    with the generated configuration.

+# Schematics Collections (`schematicCollections`)
+
+The `schematicCollections` can be placed under the `cli` option in the global `.angular.json` configuration, at the root or at project level in `angular.json` .
+
+```jsonc
+{
+  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
+  "version": 1,
+  "cli": {
+    "schematicCollections": ["@schematics/angular", "@angular/material"]
+  }
+  // ...
+}
+```
+
+## Rationale
+
+When this option is not configured and a user would like to run a schematic which is not part of `@schematics/angular`,
+the collection name needs to be provided to `ng generate` command in the form of `[collection-name:schematic-name]`. This make the `ng generate` command too verbose for repeated usages.
+
+This is where the `schematicCollections` option can be useful. When adding `@angular/material` to the list of `schematicCollections`, the generate command will try to locate the schematic in the specified collections.
+
+```
+ng generate navigation
+```
+
+is equivalent to:
+
+```
+ng generate @angular/material:navigation
+```
+
+## Conflicting schematic names
+
+When multiple collections have a schematic with the same name. Both `ng generate` and `ng new` will run the first schematic matched based on the ordering (as specified) of `schematicCollections`.

 # Schematic Prompts
 
-Schematic prompts provide the ability to introduce user interaction into the schematic execution. The schematic runtime supports the ability to allow schematic options to be configured to display a customizable question to the user and then use the response as the value for the option.  These prompts are displayed before the execution of the schematic.  This allows users direct the operation of the schematic without requiring indepth knowledge of the full spectrum of options available to the user.

 Prompts have several different types which provide the ability to display an input method that best represents the schematic option's potential values.
 
-* `confirmation` - A **yes** or **no** question; ideal for boolean options
-* `input` - textual input; ideal for string or number options
-* `list` - a predefined set of items which may be selected

-When using the _shorthand_ form, the most appropriate type will automatically be selected based on the property's schema.  In the example, the `name` prompt will use an `input` type because it it is a `string` property.  The `useColor` prompt will use a `confirmation` type because it is a boolean property with `yes` corresponding to `true` and `no` corresponding to `false`.

+# Important Considerations when Using Angular Universal
+
+## Introduction
+
+Although the goal of the Universal project is the ability to seamlessly render an Angular
+application on the server, there are some inconsistencies that you should consider. First,
+there is the obvious discrepancy between the server and browser environments. When rendering
+on the server, your application is in an ephemeral or "snapshot" state. The application is
+fully rendered once, with the resulting HTML returned, and the remaining application state
+destroyed until the next render. Next, the server environment inherently does not have the
+same capabilities as the browser (and has some that likewise the browser does not). For
+instance, the server does not have any concept of cookies. You can polyfill this and other
+functionality, but there is no perfect solution for this. In later sections, we'll walk
+through potential mitigations to reduce the scope of errors when rendering on the server.
+
+Please also note the goal of SSR: improved initial render time for your application. This
+means that anything that has the potential to reduce the speed of your application in this
+initial render should be avoided or sufficiently guarded against. Again, we'll review how
+to accomplish this in later sections.
+
+## "window is not defined"
+
+One of the most common issues when using Angular Universal is the lack of browser global
+variables in the server environment. This is because the Universal project uses
+[domino](https://github.com/fgnass/domino) as the server DOM rendering engine. As a result,
+there is certain functionality that won't be present or supported on the server. This
+includes the `window` and `document` global objects, cookies, certain HTML elements (like canvas),
+and several others. There is no exhaustive list, so please be aware of the fact that if you
+see an error like this, where a previously-accessible global is not defined, it's likely because
+that global is not available through domino.
+
+> Fun fact: Domino stands for "DOM in Node"
+
+### How to fix?
+
+#### Strategy 1: Injection
+
+Frequently, the needed global is available through the Angular platform via Dependency Injection (DI).
+For instance, the global `document` is available through the `DOCUMENT` token. Additionally, a _very_
+primitive version of both `window` and `location` exist through the `DOCUMENT` object. For example:
+
+```ts
+// example.service.ts
+import { Injectable, Inject } from '@angular/core';
+import { DOCUMENT } from '@angular/common';
+
+@Injectable()
+export class ExampleService {
+  constructor(@Inject(DOCUMENT) private _doc: Document) {}
+
+  getWindow(): Window | null {
+    return this._doc.defaultView;
+  }
+
+  getLocation(): Location {
+    return this._doc.location;
+  }
+
+  createElement(tag: string): HTMLElement {
+    return this._doc.createElement(tag);
+  }
+}
+```
+
+Please be judicious about using these references, and lower your expectations about their capabilities. `localStorage`
+is one frequently-requested API that won't work how you want it to out of the box. If you need to write your own library
+components, please consider using this method to provide similar functionality on the server (this is what Angular CDK
+and Material do).
+
+#### Strategy 2: Guards
+
+If you can't inject the proper global value you need from the Angular platform, you can "guard" against
+invocation of browser code, so long as you don't need to access that code on the server. For instance,
+often invocations of the global `window` element are to get window size, or some other visual aspect.
+However, on the server, there is no concept of "screen", and so this functionality is rarely needed.
+
+You may read online and elsewhere that the recommended approach is to use `isPlatformBrowser` or
+`isPlatformServer`. This guidance is **incorrect**. This is because you wind up creating platform-specific
+code branches in your application code. This not only increases the size of your application unnecessarily,
+but it also adds complexity that then has to be maintained. By separating code into separate platform-specific
+modules and implementations, your base code can remain about business logic, and platform-specific exceptions
+are handled as they should be: on a case-by-case abstraction basis. This can be accomplished using Angular's Dependency
+Injection (DI) in order to remove the offending code and drop in a replacement at runtime. Here's an example:
+
+```ts
+// window-service.ts
+import { Injectable } from '@angular/core';
+
+@Injectable()
+export class WindowService {
+  getWidth(): number {
+    return window.innerWidth;
+  }
+}
+```
+
+```ts
+// server-window.service.ts
+import { Injectable } from '@angular/core';
+import { WindowService } from './window.service';
+
+@Injectable()
+export class ServerWindowService extends WindowService {
+  getWidth(): number {
+    return 0;
+  }
+}
+```
+
+```ts
+// app-server.module.ts
+import {NgModule} from '@angular/core';
+import {WindowService} from './window.service';
+import {ServerWindowService} from './server-window.service';
+
+@NgModule({
+  providers: [{
+    provide: WindowService,
+    useClass: ServerWindowService,
+  }]
+})
+```
+
+If you have a component provided by a third-party that is not Universal-compatible out of the box,
+you can create two separate modules for browser and server (the server module you should already have),
+in addition to your base app module. The base app module will contain all of your platform-agnostic code,
+the browser module will contain all of your browser-specific/server-incompatible code, and vice-versa for
+your server module. In order to avoid editing too much template code, you can create a no-op component
+to drop in for the library component. Here's an example:
+
+```ts
+// example.component.ts
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'example-component',
+  template: `<library-component></library-component>`, // this is provided by a third-party lib
+  // that causes issues rendering on Universal
+})
+export class ExampleComponent {}
+```
+
+```ts
+// app.module.ts
+import {NgModule} from '@angular/core';
+import {ExampleComponent} from './example.component';
+
+@NgModule({
+  declarations: [ExampleComponent],
+})
+```
+
+```ts
+// browser-app.module.ts
+import {NgModule} from '@angular/core';
+import {LibraryModule} from 'some-lib';
+import {AppModule} from './app.module';
+
+@NgModule({
+  imports: [AppModule, LibraryModule],
+})
+```
+
+```ts
+// library-shim.component.ts
+import { Component } from '@angular/core';
+
+@Component({
+  selector: 'library-component',
+  template: '',
+})
+export class LibraryShimComponent {}
+```
+
+```ts
+// server.app.module.ts
+import { NgModule } from '@angular/core';
+import { LibraryShimComponent } from './library-shim.component';
+import { AppModule } from './app.module';
+
+@NgModule({
+  imports: [AppModule],
+  declarations: [LibraryShimComponent],
+})
+export class ServerAppModule {}
+```
+
+#### Strategy 3: Shims
+
+If all else fails, and you simply must have access to some sort of browser functionality, you can patch
+the global scope of the server environment to include the globals you need. For instance:
+
+```ts
+// server.ts
+global['window'] = {
+  // properties you need implemented here...
+};
+```
+
+This can be applied to any undefined element. Please be careful when you do this, as playing with the global
+scope is generally considered an anti-pattern.
+
+> Fun fact: a shim is a patch for functionality that will never be supported on a given platform. A
+> polyfill is a patch for functionality that is planned to be supported, or is supported on newer versions
+
+## Application is slow, or worse, won't render
+
+The Angular Universal rendering process is straightforward, but just as simply can be blocked or slowed down
+by well-meaning or innocent-looking code. First, some background on the rendering process. When a render
+request is made for platform-server (the Angular Universal platform), a single route navigation is executed.
+When that navigation completes, meaning that all Zone.js macrotasks are completed, the DOM in whatever state
+it's in at that time is returned to the user.
+
+> A Zone.js macrotask is just a JavaScript macrotask that executes in/is patched by Zone.js
+
+This means that if there is a process, like a microtask, that takes up ticks to complete, or a long-standing
+HTTP request, the rendering process will not complete, or will take longer. Macrotasks include calls to globals
+like `setTimeout` and `setInterval`, and `Observables`. Calling these without cancelling them, or letting them run
+longer than needed on the server could result in suboptimal rendering.

+Similarly to the above section on waiting for macrotasks to complete, the flip-side is that the platform will
+not wait for microtasks to complete before finishing the render. In Angular Universal, we have patched the
+Angular HTTP client to turn it into a macrotask, to ensure that any needed HTTP requests complete for a given
+render. However, this type of patch may not be appropriate for all microtasks, and so it is recommended you use
+your best judgment on how to proceed. You can look at the code reference for how Universal wraps a task to turn
+it into a macrotask, or you can simply opt to change the server behavior of the given tasks.

-# `/lib` Folder
-
-This folder includes bootstrap code for the various tools included in this repository. Also
-included is the packages meta-information package in `packages.ts`. This is used to read and
-understand all the monorepo information (contained in the `.monorepo.json` file, and `package.json`
-files across the repo).
-
-`bootstrap-local.js` should be included when running files from this repository without compiling
-first. It allows for compiling and loading packages in memory directly from the repo. Not only
-does the `devkit-admin` scripts use this to include the library, but also all binaries linked
-locally (like `schematics` and `ng`), when not using the npm published packages.

+Run `ng generate component component-name` to generate a new component. You can also use `ng generate --help` to see all the available schematics you can generate.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `-prod` flag for a production build.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).

+ * The current setup is for so-called "evergreen" browsers; the last versions of browsers that

+ * into that file, and then add the following code before importing zone.js.
+ * import './zone-flags.ts';
+ *
+ * The flags allowed in zone-flags.ts are listed here.
+ *
+ * The following flags will work for all browsers.
+ *
+ * (window as any).__Zone_disable_requestAnimationFrame = true; // disable patch requestAnimationFrame
+ * (window as any).__Zone_disable_on_property = true; // disable patch onProperty such as onclick
+ * (window as any).__zone_symbol__UNPATCHED_EVENTS = ['scroll', 'mousemove']; // disable patch specified eventNames
+ *
+ *  in IE/Edge developer tools, the addEventListener will also be wrapped by zone.js
+ *  with the following flag, it will bypass `zone.js` patch for IE/Edge
+ *

-
-## Installation
-
-**BEFORE YOU INSTALL:** please read the [prerequisites](#prerequisites)
-
-### Install Globally
-```bash
-npm install -g @angular/cli
-```
-
-### Install Locally
-```bash
-npm install @angular/cli
-```
-
-To run a locally installed version of the angular-cli, you can call `ng` commands directly by adding the `.bin` folder within your local `node_modules` folder to your PATH. The `node_modules` and `.bin` folders are created in the directory where `npm install @angular/cli` was run upon completion of the install command.
-
-Alternatively, you can install [npx](https://www.npmjs.com/package/npx) and run `npx ng <command>` within the local directory where `npm install @angular/cli` was run, which will use the locally installed angular-cli.
-
-### Install Specific Version (Example: 6.1.1)
-```bash
-npm install -g @angular/cli@6.1.1
-```
-
-## Usage
-
-```bash
-ng help
-```
-
-### Generating and serving an Angular project via a development server
-
-```bash
-ng new PROJECT-NAME
-cd PROJECT-NAME
-ng serve
-```
-Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-You can configure the default HTTP host and port used by the development server with two command-line options :
-
-```bash
-ng serve --host 0.0.0.0 --port 4201
-```
-
-### Generating Components, Directives, Pipes and Services
-
-You can use the `ng generate` (or just `ng g`) command to generate Angular components:
-
-```bash
-ng generate component my-new-component
-ng g component my-new-component # using the alias
-
-# components support relative path generation
-# if in the directory src/app/feature/ and you run
-ng g component new-cmp
-# your component will be generated in src/app/feature/new-cmp
-# but if you were to run
-ng g component ./newer-cmp
-# your component will be generated in src/app/newer-cmp
-# if in the directory src/app you can also run
-ng g component feature/new-cmp
-# and your component will be generated in src/app/feature/new-cmp
-```
-You can find all possible blueprints in the table below:
-
-Scaffold  | Usage
----       | ---
-[Component](https://angular.io/cli/generate#component)      | `ng g component my-new-component`
-[Directive](https://angular.io/cli/generate#directive)      | `ng g directive my-new-directive`
-[Pipe](https://angular.io/cli/generate#pipe)                | `ng g pipe my-new-pipe`
-[Service](https://angular.io/cli/generate#service)          | `ng g service my-new-service`
-[Class](https://angular.io/cli/generate#class)              | `ng g class my-new-class`
-[Guard](https://angular.io/cli/generate#guard)              | `ng g guard my-new-guard`
-[Interface](https://angular.io/cli/generate#interface)      | `ng g interface my-new-interface`
-[Enum](https://angular.io/cli/generate#enum)                | `ng g enum my-new-enum`
-[Module](https://angular.io/cli/generate#module)            | `ng g module my-module`
-
-
-
-
-angular-cli will add reference to `components`, `directives` and `pipes` automatically in the `app.module.ts`. If you need to add this references to another custom module, follow these steps:
-
- 1. `ng g module new-module` to create a new module
- 2.  call `ng g component new-module/new-component`
-
-This should add the new `component`, `directive` or `pipe` reference to the `new-module` you've created.
-
-### Updating Angular CLI
-
-If you're using Angular CLI `1.0.0-beta.28` or less, you need to uninstall `angular-cli` package. It should be done due to changing of package's name and scope from `angular-cli` to `@angular/cli`:
-```bash
-npm uninstall -g angular-cli
-npm uninstall --save-dev angular-cli
-```
-
-To update Angular CLI to a new version, you must update both the global package and your project's local package.
-
-Global package:
-```bash
-npm uninstall -g @angular/cli
-npm cache verify
-# if npm version is < 5 then use `npm cache clean`
-npm install -g @angular/cli@latest
-```
-
-Local project package:
-```bash
-rm -rf node_modules dist # use rmdir /S/Q node_modules dist in Windows Command Prompt; use rm -r -fo node_modules,dist in Windows PowerShell
-npm install --save-dev @angular/cli@latest
-npm install
-```
-
-If you are updating to 1.0 from a beta or RC version, check out our [1.0 Update Guide](https://github.com/angular/angular-cli/wiki/stories-1.0-update).
-
-You can find more details about changes between versions in [the Releases tab on GitHub](https://github.com/angular/angular-cli/releases).
-
-
-## Development Hints for working on Angular CLI
-
-### Working with master
-
-```bash
-git clone https://github.com/angular/angular-cli.git
-yarn
-npm run build
-cd dist/@angular/cli
-npm link
-```
-
-`npm link` is very similar to `npm install -g` except that instead of downloading the package
-from the repo, the just built `dist/@angular/cli/` folder becomes the global package.
-Additionally, this repository publishes several packages and we use special logic to load all of them
-on development setups.
-
-Any changes to the files in the `angular-cli/` folder will immediately affect the global `@angular/cli` package,
-meaning that, in order to quickly test any changes you make to the cli project, you should simply just run `npm run build`
-again.
-
-Now you can use `@angular/cli` via the command line:
-
-```bash
-ng new foo
-cd foo
-npm link @angular/cli
-ng serve
-```
-
-`npm link @angular/cli` is needed because by default the globally installed `@angular/cli` just loads
-the local `@angular/cli` from the project which was fetched remotely from npm.
-`npm link @angular/cli` symlinks the global `@angular/cli` package to the local `@angular/cli` package.
-Now the `angular-cli` you cloned before is in three places:
-The folder you cloned it into, npm's folder where it stores global packages and the Angular CLI project you just created.
-
-You can also use `ng new foo --link-cli` to automatically link the `@angular/cli` package.
-
-Please read the official [npm-link documentation](https://docs.npmjs.com/cli/link)
-and the [npm-link cheatsheet](http://browsenpm.org/help#linkinganynpmpackagelocally) for more information.
-
-To run the Angular CLI E2E test suite, use the `node ./tests/legacy-cli/run_e2e` command.
-It can also receive a filename to only run that test (e.g. `node ./tests/legacy-cli/run_e2e tests/legacy-cli/e2e/tests/build/dev-build.ts`).
-
-As part of the test procedure, all packages will be built and linked.
-You will need to re-run `npm link` to re-link the development Angular CLI environment after tests finish.
-
-### Debugging with VS Code
-
-In order to debug some Angular CLI behaviour using Visual Studio Code, you can run `npm run build`, and then use a launch configuration like the following:
-
-```json
-{
-    "type": "node",
-    "request": "launch",
-    "name": "ng serve",
-    "cwd": "<path to an Angular project generated with Angular-CLI>",
-    "program": "${workspaceFolder}/dist/@angular/cli/bin/ng",
-    "args": [
-        "<ng command>",
-        ...other arguments
-    ],
-    "console": "integratedTerminal"
-}
-```
-
-Then you can add breakpoints in `dist/@angular` files.
-
-For more informations about Node.js debugging in VS Code, see the related [VS Code Documentation](https://code.visualstudio.com/docs/nodejs/nodejs-debugging).
-
-### CPU Profiling
-
-In order to investigate performance issues, CPU profiling is often useful.
-
-To capture a CPU profiling, you can:
-1. install the v8-profiler-node8 dependency: `npm install v8-profiler-node8 --no-save`
-1. set the NG_CLI_PROFILING Environment variable to the file name you want:
-    * on Unix systems (Linux & Mac OS X): ̀`export NG_CLI_PROFILING=my-profile`
-    * on Windows: ̀̀`setx NG_CLI_PROFILING my-profile`
-
-Then, just run the ng command on which you want to capture a CPU profile.
-You will then obtain a `my-profile.cpuprofile` file in the folder from wich you ran the ng command.
-
-You can use the Chrome Devtools to process it. To do so:
-1. open `chrome://inspect/#devices` in Chrome
-1. click on "Open dedicated DevTools for Node"
-1. go to the "profiler" tab
-1. click on the "Load" button and select the generated .cpuprofile file
-1. on the left panel, select the associated file
-
-In addition to this one, another, more elaborated way to capture a CPU profile using the Chrome Devtools is detailed in https://github.com/angular/angular-cli/issues/8259#issue-269908550.

-The command can be used to build a project of type "application" or "library".
-When used to build a library, a different builder is invoked, and only the `ts-config`, `configuration`, and `watch` options are applied.
-All other options apply only to building applications.
-
-The application builder uses the [webpack](https://webpack.js.org/) build tool, with default configuration options specified in the workspace configuration file (`angular.json`) or with a named alternative configuration.
-A "production" configuration is created by default when you use the CLI to create the project, and you can use that configuration by specifying the `--configuration="production"` or the `--prod="true"` option.
-
-The configuration options generally correspond to the command options.
-You can override individual configuration defaults by specifying the corresponding options on the command line.
-The command can accept option names given in either dash-case or camelCase.
-Note that in the configuration file, you must specify names in camelCase.
-
-Some additional options can only be set through the configuration file,
-either by direct editing or with the `ng config` command.
-These include `assets`, `styles`, and `scripts` objects that provide runtime-global resources to include in the project.
-Resources in CSS, such as images and fonts, are automatically written and fingerprinted at the root of the output folder.
-
-For further details, see [Workspace Configuration](guide/workspace-config).

-When a project name is not supplied, executes the `deploy` builder for the default project.

-To use the `ng deploy` command, use `ng add` to add a package that implements deployment capabilities to your favorite platform.

-Creates and initializes a new Angular app that is the default project for a new workspace.

-Provides interactive prompts for optional configuration, such as adding routing support.
-All prompts can safely be allowed to default.
-
-* The new workspace folder is given the specified project name, and contains configuration files at the top level.
-
-* By default, the files for a new initial app (with the same name as the workspace) are placed in the `src/` subfolder. Corresponding end-to-end tests are placed in the `e2e/` subfolder.
-
-* The new app's configuration appears in the `projects` section of the `angular.json` workspace configuration file, under its project name.
-
-* Subsequent apps that you generate in the workspace reside in the `projects/` subfolder.
-
-If you plan to have multiple apps in the workspace, you can create an empty workspace by setting the `--createApplication` option to false.
-You can then use `ng generate application` to create an initial app.
-This allows a workspace name different from the initial app name, and ensures that all apps reside in the `/projects` subfolder, matching the structure of the configuration file.

-Architect is the tool that the CLI uses to perform complex tasks such as compilation, according to provided configurations.
-The CLI commands run Architect targets such as `build`, `serve`, `test`, and `lint`.
-Each named target has a default configuration, specified by an "options" object,
-and an optional set of named alternate configurations in the "configurations" object.
-
-For example, the "serve" target for a newly generated app has a predefined
-alternate configuration named "production".
-
-You can define new targets and their configuration options in the "architect" section
-of the `angular.json` file.
-If you do so, you can run them from the command line using the `ng run` command.
-Execute the command using the following format.

-Perform a basic update to the current stable release of the core framework and CLI by running the following command.
-
-```
-ng update @angular/cli @angular/core
-```
-
-To update to the next beta or pre-release version, use the `--next=true` option.
-
-To update from one major version to another, use the format
-`ng update @angular/cli@^<major_version> @angular/core@^<major_version>`.
-
-We recommend that you always update to the latest patch version, as it contains fixes we released since the initial major release.
-For example, use the following command to take the latest 7.x.x version and use that to update.
-
-`ng update @angular/cli@^7 @angular/core@^7`
-
-For detailed information and guidance on updating your application, see the interactive [Angular Update Guide](https://update.angular.io/).

+You can help the Angular Team to prioritize features and improvements by permitting the Angular team to send command-line command usage statistics to Google.
+The Angular Team does not collect usage statistics unless you explicitly opt in. When installing the Angular CLI you are prompted to allow global collection of usage statistics.
+If you say no or skip the prompt, no data is collected.
+
+### What is collected?
+
+Usage analytics include the commands and selected flags for each execution.
+Usage analytics may include the following information:
+
+- Your operating system \(macOS, Linux distribution, Windows\) and its version.
+- Package manager name and version \(local version only\).
+- Node.js version \(local version only\).
+- Angular CLI version \(local version only\).
+- Command name that was run.
+- Workspace information, the number of application and library projects.
+- For schematics commands \(add, generate and new\), the schematic collection and name and a list of selected flags.
+- For build commands \(build, serve\), the builder name, the number and size of bundles \(initial and lazy\), compilation units, the time it took to build and rebuild, and basic Angular-specific API usage.
+
+Only Angular owned and developed schematics and builders are reported.
+Third-party schematics and builders do not send data to the Angular Team.

+The command can be used to build a project of type "application" or "library".
+When used to build a library, a different builder is invoked, and only the `ts-config`, `configuration`, `poll` and `watch` options are applied.
+All other options apply only to building applications.
+
+The application builder uses the [esbuild](https://esbuild.github.io/) build tool, with default configuration options specified in the workspace configuration file (`angular.json`) or with a named alternative configuration.
+A "development" configuration is created by default when you use the CLI to create the project, and you can use that configuration by specifying the `--configuration development`.
+
+The configuration options generally correspond to the command options.
+You can override individual configuration defaults by specifying the corresponding options on the command line.
+The command can accept option names given in dash-case.
+Note that in the configuration file, you must specify names in camelCase.
+
+Some additional options can only be set through the configuration file,
+either by direct editing or with the `ng config` command.
+These include `assets`, `styles`, and `scripts` objects that provide runtime-global resources to include in the project.
+Resources in CSS, such as images and fonts, are automatically written and fingerprinted at the root of the output folder.
+
+For further details, see [Workspace Configuration](reference/configs/workspace-config).

+Angular CLI saves a number of cachable operations on disk by default.
+
+When you re-run the same build, the build system restores the state of the previous build and re-uses previously performed operations, which decreases the time taken to build and test your applications and libraries.
+
+To amend the default cache settings, add the `cli.cache` object to your [Workspace Configuration](reference/configs/workspace-config).
+The object goes under `cli.cache` at the top level of the file, outside the `projects` sections.
+
+```jsonc
+{
+  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
+  "version": 1,
+  "cli": {
+    "cache": {
+      // ...
+    },
+  },
+  "projects": {},
+}
+```
+
+For more information, see [cache options](reference/configs/workspace-config#cache-options).
+
+### Cache environments
+
+By default, disk cache is only enabled for local environments. The value of environment can be one of the following:
+
+- `all` - allows disk cache on all machines.
+- `local` - allows disk cache only on development machines.
+- `ci` - allows disk cache only on continuous integration (CI) systems.
+
+To change the environment setting to `all`, run the following command:
+
+```bash
+ng config cli.cache.environment all
+```
+
+For more information, see `environment` in [cache options](reference/configs/workspace-config#cache-options).
+
+<div class="alert is-helpful">
+
+The Angular CLI checks for the presence and value of the `CI` environment variable to determine in which environment it is running.
+
+</div>
+
+### Cache path
+
+By default, `.angular/cache` is used as a base directory to store cache results.
+
+To change this path to `.cache/ng`, run the following command:
+
+```bash
+ng config cli.cache.path ".cache/ng"
+```

+Setting up autocompletion configures your terminal, so pressing the `<TAB>` key while in the middle
+of typing will display various commands and options available to you. This makes it very easy to
+discover and use CLI commands without lots of memorization.
+
+![A demo of Angular CLI autocompletion in a terminal. The user types several partial `ng` commands,
+using autocompletion to finish several arguments and list contextual options.
+](assets/images/guide/cli/completion.gif)
+
+## Automated setup
+
+The CLI should prompt and ask to set up autocompletion for you the first time you use it (v14+).
+Simply answer "Yes" and the CLI will take care of the rest.
+
+```
+$ ng serve
+? Would you like to enable autocompletion? This will set up your terminal so pressing TAB while typing Angular CLI commands will show possible options and autocomplete arguments. (Enabling autocompletion will modify configuration files in your home directory.) Yes
+Appended `source <(ng completion script)` to `/home/my-username/.bashrc`. Restart your terminal or run:
+
+source <(ng completion script)
+
+to autocomplete `ng` commands.
+
+# Serve output...
+```
+
+If you already refused the prompt, it won't ask again. But you can run `ng completion` to
+do the same thing automatically.
+
+This modifies your terminal environment to load Angular CLI autocompletion, but can't update your
+current terminal session. Either restart it or run `source <(ng completion script)` directly to
+enable autocompletion in your current session.
+
+Test it out by typing `ng ser<TAB>` and it should autocomplete to `ng serve`. Ambiguous arguments
+will show all possible options and their documentation, such as `ng generate <TAB>`.
+
+## Manual setup
+
+Some users may have highly customized terminal setups, possibly with configuration files checked
+into source control with an opinionated structure. `ng completion` only ever appends Angular's setup
+to an existing configuration file for your current shell, or creates one if none exists. If you want
+more control over exactly where this configuration lives, you can manually set it up by having your
+shell run at startup:
+
+```bash
+source <(ng completion script)
+```
+
+This is equivalent to what `ng completion` will automatically set up, and gives power users more
+flexibility in their environments when desired.
+
+## Platform support
+
+Angular CLI supports autocompletion for the Bash and Zsh shells on MacOS and Linux operating
+systems. On Windows, Git Bash and [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/)
+using Bash or Zsh are supported.
+
+## Global install
+
+Autocompletion works by configuring your terminal to invoke the Angular CLI on startup to load the
+setup script. This means the terminal must be able to find and execute the Angular CLI, typically
+through a global install that places the binary on the user's `$PATH`. If you get
+`command not found: ng`, make sure the CLI is installed globally which you can do with the `-g`
+flag:
+
+```bash
+npm install -g @angular/cli
+```

+A workspace has a single CLI configuration file, `angular.json`, at the top level.
+The `projects` object contains a configuration object for each project in the workspace.
+
+You can edit the configuration directly in a code editor,

+
+The configurable property names match command option names,

+The command takes an optional project name, as specified in the `projects` section of the `angular.json` workspace configuration file.
+When a project name is not supplied, executes the `deploy` builder for the default project.
+
+To use the `ng deploy` command, use `ng add` to add a package that implements deployment capabilities to your favorite platform.
+Adding the package automatically updates your workspace configuration, adding a deployment
+[CLI builder](tools/cli/cli-builder).
+For example:
+
+```json

+The command takes an optional project name, as specified in the `projects` section of the `angular.json` workspace configuration file.
+When a project name is not supplied, executes the `lint` builder for all projects.
+
+To use the `ng lint` command, use `ng add` to add a package that implements linting capabilities. Adding the package automatically updates your workspace configuration, adding a lint [CLI builder](tools/cli/cli-builder).
+For example:
+
+```json
+"projects": {
+  "my-project": {

+Creates and initializes a new Angular application that is the default project for a new workspace.

+Provides interactive prompts for optional configuration, such as adding routing support.
+All prompts can safely be allowed to default.
+
+- The new workspace folder is given the specified project name, and contains configuration files at the top level.
+
+- By default, the files for a new initial application (with the same name as the workspace) are placed in the `src/` subfolder.
+- The new application's configuration appears in the `projects` section of the `angular.json` workspace configuration file, under its project name.
+
+- Subsequent applications that you generate in the workspace reside in the `projects/` subfolder.
+
+If you plan to have multiple applications in the workspace, you can create an empty workspace by using the `--no-create-application` option.
+You can then use `ng generate application` to create an initial application.
+This allows a workspace name different from the initial app name, and ensures that all applications reside in the `/projects` subfolder, matching the structure of the configuration file.

+Architect is the tool that the CLI uses to perform complex tasks such as compilation, according to provided configurations.
+The CLI commands run Architect targets such as `build`, `serve`, `test`, and `lint`.
+Each named target has a default configuration, specified by an `options` object,
+and an optional set of named alternate configurations in the `configurations` object.
+
+For example, the `serve` target for a newly generated app has a predefined
+alternate configuration named `production`.
+
+You can define new targets and their configuration options in the `architect` section
+of the `angular.json` file which you can run them from the command line using the `ng run` command.

+Perform a basic update to the current stable release of the core framework and CLI by running the following command.
+
+```
+ng update @angular/cli @angular/core
+```
+
+To update to the next beta or pre-release version, use the `--next` option.
+
+To update from one major version to another, use the format
+
+```
+ng update @angular/cli@^<major_version> @angular/core@^<major_version>
+```
+
+We recommend that you always update to the latest patch version, as it contains fixes we released since the initial major release.
+For example, use the following command to take the latest 10.x.x version and use that to update.
+
+```
+ng update @angular/cli@^10 @angular/core@^10
+```
+
+For detailed information and guidance on updating your application, see the interactive [Angular Update Guide](https://update.angular.dev/).

+# `@angular/pwa`
+
+This is a [schematic](https://angular.dev/tools/cli/schematics) for adding
+[Progressive Web App](https://web.dev/progressive-web-apps/) support to an Angular project. Run the
+schematic with the [Angular CLI](https://angular.dev/tools/cli):
+
+```shell
+ng add @angular/pwa --project <project-name>
+```
+
+Executing the command mentioned above will perform the following actions:
+
+1. Adds [`@angular/service-worker`](https://npmjs.com/@angular/service-worker) as a dependency to your project.
+1. Enables service worker builds in the Angular CLI.
+1. Imports and registers the service worker in the application module.
+1. Updates the `index.html` file:
+   - Includes a link to add the [manifest.webmanifest](https://developer.mozilla.org/en-US/docs/Web/Manifest) file.
+   - Adds a meta tag for `theme-color`.
+1. Installs icon files to support the installed Progressive Web App (PWA).
+1. Creates the service worker configuration file called `ngsw-config.json`, specifying caching behaviors and other settings.
+
+See [Getting started with service workers](https://angular.dev/ecosystem/service-workers/getting-started)
+for more information.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# Description
+
+Jobs is the Angular DevKit subsystem for scheduling and running generic functions with clearly
+typed inputs and outputs. A `Job` instance is a function associated with metadata. You can
+schedule a job, synchronize it with other jobs, and use it to schedule other jobs.
+
+The whole API is serializable, allowing you to use a Node Stream or message channel to
+communicate between the job and the job scheduler.
+
+Jobs are lazy, cold, and guaranteed to execute exactly once when scheduled. Subscribing to a job
+returns messages from the point where the job is at.
+
+## Argument, Input, Output and Channels
+
+A job receives a single argument when scheduled and can also listen to an input channel. It can
+emit multiple outputs, and can also provide multiple output channels that emit asynchronous JSON
+messages, which can be typed.
+
+The I/O model is like that of an executable, where the argument corresponds to arguments on the
+command line, the input channel to STDIN, the output channel to STDOUT, and the channels
+would be additional output streams.
+
+## LifeCycle
+
+A `Job` goes through multiple LifeCycle messages before its completion;
+
+1. `JobState.Queued`. The job was queued and is waiting. This is the default state from the
+   scheduler.
+1. `JobState.Ready`. The job's dependencies (see
+   ["Synchronizing and Dependencies"](#Dependencies)) are done running, the argument is
+   validated, and the job is ready to execute.
+1. `JobState.Started`. The argument has been validated, the job has been called and is running.
+   This is handled by the job itself (or `createJobHandler()`).
+1. `JobState.Ended`. The job has ended and is done running. This is handled by the job itself (or
+   `createJobHandler()`).
+1. `JobState.Errored`. A unrecoverable error happened.
+
+Each state (except `Queued`) corresponds to a `JobOutboundMessage` on the `outboundBus` observable
+that triggers the state change. The `Scheduler` emits the `Ready` and `Errored` messages; the job
+implementation should not emit them, and if it does they are filtered out. You can listen for
+these messages or use the corresponding state member.
+
+The job implementation should emit the `Start` and `End` messages when it is starting the job logic
+itself. Only the first `Start` and `End` messages will be forwarded. Any more will be filtered out.
+
+The `Queued` state is set as the job is scheduled, so there is no need to listen for the message.
+
+## `Job<OutputType>` Object
+
+The `Job` object that is returned when you schedule a job provides access to the job's status and
+utilities for tracking and modifying the job.
+
+1. `id`. A unique symbol that can be used as a Map key.
+1. `description`. The description of the job from the scheduler. See `JobDescription` object.
+1. `argument`. The argument value that was used to start the job.
+1. `input`. An `Observer` that can be used to send validated inputs to the job itself.
+1. `output`. An `Observable<OutputType>` that filters out messages to get only the returned output
+   of a job.
+1. `promise`. A promise that waits for the last output of a job. Returns the last value outputted
+   (or no value if there's no last value).
+1. `state`. The current state of the job (see `LifeCycle`).
+1. `channels`. A map of side channels the user can listen to as `Observable`.
+1. `ping()`. A function that can be used to ping the job, receiving a `Promise` for when the ping
+   is answered.
+1. `stop()`. Sends a `stop` input to the job, which suggests to stop the job. The job itself can
+   choose to ignore this message.
+1. `inboundBus`. The raw input `Observer<JobInboundMessage>`. This can be used to send messages to
+   the `context.inboundBus` observable in the job. These are `JobInboundMessage` messages. See
+   ["Communicating With Jobs"](#Communicating).
+1. `outboundBus`. The raw output `Observable<JobOutput>`. This can be used to listen to messages
+   from the job. See ["Communicating With Jobs"](#Communicating).
+
+## `JobHandlerContext<I, O>` Object
+
+The `JobHandlerContext<>` is passed to the job handler code in addition to its argument. The
+context contains the following members:
+
+1. `description`. The description of the job. Its name and schemas.
+1. `scheduler`. A `Scheduler<>` instance that can be used to create additional jobs.
+1. `dependencies`. A generic list of other job instances that were run as dependencies when
+   scheduling this job. Their `id` is not guaranteed to match the `id` of the `Job<>` instance
+   itself (those `Job<>`s might just be proxies). The state of those `Job<>` is guaranteed to be
+   `JobState.Ended`, as `JobState.Errored` would have prevented this handler from running.
+1. `inboundBus`. The raw input observable, complement of the `inboundBus` observer from the `Job<>`.
+
+# Examples
+
+An example of a job that adds all input together and return the output value. We use a
+simple synchronous job registry and a simple job scheduler.
+
+```typescript
+import { jobs } from '@angular-devkit/core';
+
+const add = jobs.createJobHandle<number[], number>((input) =>
+  input.reduce((total, curr) => total + curr, 0),
+);
+
+// Register the job in a SimpleJobRegistry. Different registries have different API.
+const registry = new jobs.SimpleJobRegistry();
+const scheduler = new jobs.SimpleScheduler(registry);
+registry.register(add, {
+  name: 'add',
+  input: { type: 'array', items: { type: 'number' } },
+  output: { type: 'number' },
+});
+
+scheduler
+  .schedule('add', [1, 2, 3, 4])
+  .promise.then((output) => console.log('1 + 2 + 3 + 4 is ' + output));
+```
+
+# Creating Jobs
+
+A job is at its core a function with a description object attached to it. The description object
+stores the JSON schemas used to validate the types of the argument passed in, the input and
+output values. By default, a job accepts and can output any JSON object.
+
+```typescript
+import { Observable } from 'rxjs';
+import { jobs } from '@angular-devkit/core';
+
+const argument = {
+  type: 'array',
+  items: { type: 'number' },
+};
+const output = {
+  type: 'number',
+};
+
+export function add(argument: number[]): Observable<jobs.JobOutboundMessage<number>> {
+  return new Observable((o) => {
+    o.next({ kind: jobs.JobOutboundMessageKind.Start });
+    o.next({
+      kind: jobs.JobOutboundMessageKind.Output,
+      output: argument.reduce((total, curr) => total + curr, 0),
+    });
+    o.next({ kind: jobs.JobOutboundMessageKind.End });
+    o.complete();
+  });
+}
+
+// Add a property to `add` to make it officially a JobHandler. The Job system does not recognize
+// any function as a JobHandler.
+add.jobDescription = {
+  argument: argument,
+  output: output,
+};
+
+// Call the job with an array as argument, and log its output.
+declare const scheduler: jobs.Scheduler;
+scheduler.schedule('add', [1, 2, 3, 4]).output.subscribe((x) => console.log(x)); // Will output 10.
+```
+
+This is a lot of boilerplate, so we made some helpers to improve readability and manage argument,
+input and output automatically:
+
+```typescript
+// Add is a JobHandler function, like the above.
+export const add = jobs.createJobHandler<number[], number>((argument) =>
+  argument.reduce((total, curr) => total + curr, 0),
+);
+
+// Schedule like above.
+```
+
+You can also return a Promise or an Observable, as jobs are asynchronous. This helper will set
+start and end messages appropriately. It will also manage channels automatically (see below).
+
+A more complex job can be declared like this:
+
+```typescript
+import { Observable } from 'rxjs';
+import { jobs } from '@angular-devkit/core';
+
+// Show progress with each count in a separate output channel. Output "more" in a channel.
+export const count = jobs.createJobHandler<number, number>(
+  // Receive a context that contains additional methods to create channels.
+  (argument: number, { createChannel }) =>
+    new Observable<number>((o) => {
+      const side = createChannel('side', { type: 'string', const: 'more' });
+      const progress = createChannel('progress', { type: 'number' });
+      let i = 0;
+      function doCount() {
+        o.next(i++);
+        progress.next(i / argument);
+        side.next('more');
+
+        if (i < argument) {
+          setTimeout(doCount, 100);
+        } else {
+          o.complete();
+        }
+      }
+      setTimeout(doCount, 100);
+    }),
+  {
+    argument: { type: 'number' },
+    output: { type: 'number' },
+  },
+);
+
+// Get a hold of a scheduler that refers to the job above.
+declare const scheduler: jobs.Scheduler;
+
+const job = scheduler.schedule('count', 0);
+job.getChannel('side').subscribe((x) => console.log(x));
+// You can type a channel too. Messages will be filtered out.
+job.getChannel<number>('progress', { type: 'number' }).subscribe((x) => console.log(x));
+```
+
+## <a name="Communicating"></a>Communicating With Jobs
+
+Jobs can be started and updated in a separate process or thread, and as such communication with a
+job should avoid using global objects (which might not be shared). The jobs API and schedulers
+provide 2 communication streams (one for input and the other for output), named `inboundBus` and
+`outboundBus`.
+
+### Raw Input Stream
+
+The `schedule()` function returns a `Job<>` interface that contains a `inboundBus` member of type
+`Observer<JobInboundMessage>`. All messages sent _to_ the job goes through this stream. The `kind`
+member of the `JobInboundMessage` interface dictates what kind of message it is sending:
+
+1. `JobInboundMessageKind.Ping`. A simple message that should be answered with
+   `JobOutboundMessageKind.Pong` when the job is responsive. The `id` field of the message should
+   be used when returning `Pong`.
+1. `JobInboundMessageKind.Stop`. The job should be stopped. This is used when
+   cancelling/unsubscribing from the `output` (or by calling `stop()`). Any inputs or outputs
+   after this message will be ignored.
+1. `JobInboundMessageKind.Input` is used when sending inputs to a job. These correspond to the
+   `next` methods of an `Observer` and are reported to the job through its `context.input`
+   Observable. There is no way to communicate an error to the job.
+
+Using the `createJobHandler()` helper, all those messages are automatically handled by the
+boilerplate code. If you need direct access to raw inputs, you should subscribe to the
+`context.inboundBus` Observable.
+
+### Raw Output Stream
+
+The `Job<>` interface also contains a `outboundBus` member (of type
+`Observable<JobOutboundMessage<O>>` where `O` is the typed output of the job) which is the output
+complement of `inboundBus`. All messages sent _from_ the job goes through this stream. The `kind`
+member of the `JobOutboundMessage<O>` interface dictates what kind of message it is sending:
+
+1. `JobOutboundMessageKind.Create`. The `Job<>` was created, its dependencies are done, and the
+   library is validating Argument and calling the internal job code.
+1. `JobOutboundMessageKind.Start`. The job code itself should send that message when started.
+   `createJobHandler()` will do it automatically.
+1. `JobOutboundMessageKind.End`. The job has ended. This is done by the job itself and should always
+   be sent when completed. The scheduler will listen to this message to set the state and unblock
+   dependent jobs. `createJobHandler()` automatically send this message.
+1. `JobOutboundMessageKind.Pong`. The job should answer a `JobInboundMessageKind.Ping` message with
+   this. Automatically done by `createJobHandler()`.
+1. `JobOutboundMessageKind.Output`. An `Output` has been generated by the job.
+1. `JobOutboundMessageKind.ChannelMessage`, `JobOutboundMessageKind.ChannelError` and
+   `JobOutboundMessageKind.ChannelComplete` are used for output channels. These correspond to the
+   `next`, `error` and `complete` methods of an `Observer` and are available to the callee through
+   the `job.channels` map of Observable.
+
+Those messages can be accessed directly through the `job.outboundBus` member. The job itself should
+return an `Observable<JobOutboundMessage<O>>`. The `createJobHandler()` helper handles most of use
+cases of this and makes it easier for jobs to handle this.
+
+## Job Dispatchers
+
+Dispatchers are a helper that redirect to different jobs given conditions. To create a job
+dispatcher, use the `createDispatcher()` function:
+
+```typescript
+import { jobs } from '@angular-devkit/core';
+
+// A dispatcher that installs node modules given a user's preference.
+const dispatcher = jobs.createDispatcher({
+  name: 'node-install',
+  argument: { properties: { moduleName: { type: 'string' } } },
+  output: { type: 'boolean' },
+});
+
+const npmInstall = jobs.createJobHandler(/* ... */, { name: 'npm-install' });
+const yarnInstall = jobs.createJobHandler(/* ... */, { name: 'yarn-install' });
+const pnpmInstall = jobs.createJobHandler(/* ... */, { name: 'pnpm-install' });
+
+declare const registry: jobs.SimpleJobRegistry;
+registry.register(dispatcher);
+registry.register(npmInstall);
+registry.register(yarnInstall);
+registry.register(pnpmInstall);
+
+// Default to npm.
+dispatcher.setDefaultDelegate(npmInstall.name);
+// If the user is asking for yarn over npm, uses it.
+dispatcher.addConditionalDelegate(() => userWantsYarn, yarnInstall.name);
+```
+
+## Execution Strategy
+
+Jobs are always run in parallel and will always start, but many helper functions are provided
+when creating a job to help you control the execution strategy;
+
+1. `serialize()`. Multiple runs of this job will be queued with each others.
+1. `memoize(replayMessages = false)` will create a job, or reuse the same job when inputs are
+   matching. If the inputs don't match, a new job will be started and its outputs will be stored.
+
+These strategies can be used when creating the job:
+
+```typescript
+// Same input and output as above.
+
+export const add = jobs.strategy.memoize()(
+  jobs.createJobHandler<number[], number>((argument) =>
+    argument.reduce((total, curr) => total + curr, 0),
+  ),
+);
+```
+
+Strategies can be reused to synchronize between jobs. For example, given jobs `jobA` and `jobB`,
+you can reuse the strategy to serialize both jobs together;
+
+```typescript
+const strategy = jobs.strategy.serialize();
+const jobA = strategy(jobs.createJobHandler(...));
+const jobB = strategy(jobs.createJobHandler(...));
+```
+
+Even further, we can have package A and package B run in serialization, and B and C also be
+serialized. Running A and C will run in parallel, while running B will wait for both A and C
+to finish.
+
+```typescript
+const strategy1 = jobs.strategy.serialize();
+const strategy2 = jobs.strategy.serialize();
+const jobA = strategy1(jobs.createJobHandler(...));
+const jobB = strategy1(strategy2(jobs.createJobHandler(...)));
+const jobC = strategy2(jobs.createJobHandler(...));
+```
+
+# Scheduling Jobs
+
+Jobs can be scheduled using a `Scheduler` interface, which contains a `schedule()` method:
+
+```typescript
+interface Scheduler {
+  /**
+   * Schedule a job to be run, using its name.
+   * @param name The name of job to be run.
+   * @param argument The argument to send to the job when starting it.
+   * @param options Scheduling options.
+   * @returns The Job being run.
+   */
+  schedule<I extends MinimumInputValueT, O extends MinimumOutputValueT>(
+    name: JobName,
+    argument: I,
+    options?: ScheduleJobOptions,
+  ): Job<JsonValue, O>;
+}
+```
+
+The scheduler also has a `getDescription()` method to get a `JobDescription` object for a certain
+name; that description contains schemas for the argument, input, output, and other channels:
+
+```typescript
+interface Scheduler {
+  /**
+   * Get a job description for a named job.
+   *
+   * @param name The name of the job.
+   * @returns A description, or null if the job cannot be scheduled.
+   */
+  getDescription(name: JobName): JobDescription | null;
+
+  /**
+   * Returns true if the job name has been registered.
+   * @param name The name of the job.
+   * @returns True if the job exists, false otherwise.
+   */
+  has(name: JobName): boolean;
+}
+```
+
+Finally, the scheduler interface has a `pause()` method to stop scheduling. This will queue all
+jobs and wait for the unpause function to be called before unblocking all the jobs scheduled.
+This does not affect already running jobs.
+
+```typescript
+interface Scheduler {
+  /**
+   * Pause the scheduler, temporary queueing _new_ jobs. Returns a resume function that should be
+   * used to resume execution. If multiple `pause()` were called, all their resume functions must
+   * be called before the Scheduler actually starts new jobs. Additional calls to the same resume
+   * function will have no effect.
+   *
+   * Jobs already running are NOT paused. This is pausing the scheduler only.
+   *
+   * @returns A function that can be run to resume the scheduler. If multiple `pause()` calls
+   *          were made, all their return function must be called (in any order) before the
+   *          scheduler can resume.
+   */
+  pause(): () => void;
+}
+```
+
+## <a name="Dependencies"></a>Synchronizing and Dependencies
+
+When scheduling jobs, it is often necessary to run jobs after certain other jobs are finished.
+This is done through the `dependencies` options in the `schedule()` method.
+
+These jobs will also be passed to the job being scheduled, through its context. This can be
+useful if, for example, the output of those jobs are of a known type, or have known side channels.
+
+An example of this would be a compiler that needs to know the output directory of other compilers
+before it, in a tool chain.
+
+### Dependencies
+
+When scheduling jobs, the user can add a `dependencies` field to the scheduling options. The
+scheduler will wait for those dependencies to finish before running the job, and pass those jobs
+in the context of the job.
+
+### Accessing Dependencies
+
+Jobs are called with a `JobHandlerContext` as a second argument, which contains a
+`dependencies: Job<JsonValue>[]` member which contains all dependencies that were used when
+scheduling the job. Those aren't fully typed as they are determined by the user, and not the job
+itself. They also can contain jobs that are not finished, and the job should use the `state`
+member of the job itself before trying to access its content.
+
+### Scheduler Sub Jobs
+
+The `JobHandlerContext` also contains a `scheduler` member which can be used to schedule jobs
+using the same scheduler that was used for the job. This allows jobs to call other jobs
+and wait for them to end.
+
+## Available Schedulers
+
+The Core Angular DevKit library provides 2 implementations for the `Scheduler` interface:
+
+## SimpleJobRegistry
+
+Available in the jobs namespace. A registry that accept job registration, and can also schedule
+jobs.
+
+```typescript
+import { jobs } from '@angular-devkit/core';
+
+const add = jobs.createJobHandler<number[], number>((argument) =>
+  argument.reduce((total, curr) => total + curr, 0),
+);
+
+// Register the job in a SimpleJobRegistry. Different registries have different API.
+const registry = new jobs.SimpleJobRegistry();
+const scheduler = new SimpleJobScheduler(registry);
+
+registry.register(add, {
+  name: 'add',
+  argument: { type: 'array', items: { type: 'number' } },
+  output: { type: 'number' },
+});
+
+scheduler.schedule('add', [1, 2, 3, 4]);
+```
+
+## NodeModuleJobRegistry
+
+Available through `@angular-devkit/core/node`.
+
+A scheduler that loads jobs using their node package names. These jobs need to use the
+`createJobHandler()` helper and report their argument/input/output schemas that way.
+
+```typescript
+declare const registry: NodeModuleJobRegistry;
+const scheduler = new SimpleJobScheduler(registry);
+
+scheduler.schedule('some-node-package#someExport', 'input');
+```
+
+# Gotchas
+
+1. Deadlocking Dependencies  
+   It is impossible to add dependencies to an already running job, but it is entirely possible to
+   get locked between jobs. Be aware of your own dependencies.
+
+1. Using `job.promise`  
+   `job.promise` waits for the job to ends. Don't rely on it unless you know the job is not
+   watching and running for a long time. If you aren't sure, use
+   `job.output.pipe(first()).toPromise()` instead which will return the first next output,
+   regardless of whether the job watches and rerun or not.
+
+# FAQ
+
+1. Laziness  
+   A job is lazy until executed, but its messages will be replayed when resubscribed.
+
+1. Serialize Strategy vs Dependencies  
+   Strategies are functions that transform the execution of a job, and can be used when
+   declaring the job, or registering it. Dependencies, on the other hand, are listed when
+   scheduling a job to order jobs during scheduling.
+
+   A job has no control over the way it's scheduled, and its dependencies. It can, however,
+   declare that it shouldn't run at the same time as itself. Alternatively, a user could
+   schedule a job twice and imply that the second run should wait for the first to finish. In
+   practice, this would be equivalent to having the job be serialized, but the important detail
+   is in _whom_ is defining the rules; using the `serialize()` strategy, the job implementation
+   is, while when using dependencies, the user is.
+
+   The user does not need to know how to job needs to synchronize with itself, and the job does
+   not need to know how it synchronizes with other jobs that it doesn't know about. That's part
+   of the strength of this system as every job can be developed in a vacuum, only caring about
+   its contracts (argument, input and output) and its own synchronization.

 # Overview

 Jobs is a high-order API that adds inputs, runtime type checking, sequencing, and other
 functionality on top of RxJS' `Observable`s.

 # Limitations
+
 Jobs input, output and argument must be serializable to JSONs. This is a big limitation in usage,
 but comes with the benefit that jobs can be serialized and called across memory boundaries. An
 example would be an operator that takes a module path and run the job from that path in a separate
 process. Or even a separate server, using HTTP calls.
- 
+
 Another limitation is that the boilerplate is complex. Manually managing start/end life cycle, and
 other messages such as ping/pong, etc. is tedious and requires a lot of code. A good way to keep
 this limitation under control is to provide helpers to create `JobHandler`s which manage those

-# Angular Devkit Benchmark
-
-This tool provides benchmark information for processes.
-The tool will gathering metrics from a given command, then average them out over the total runs.
-
-It currently shows only time, process, cpu, and memory used but might be extended in the future.
-
-This tool was created to provide an objective and reproducible way of benchmarking process
-performance.
-
-Given a process (or its source code), process inputs and environment, keeping two of these elements
-constant while varying the third should allow for meaningful benchmarks over time.
-
-In the context of the DevKit, we publish many CLI tools and have access to their source code.
-By tracking tool resource usage we can catch performance regressions or improvements on our CI.
-
-
-## STABILITY AND SUPPORT DISCLAIMER
-
-This package is not currently stable. Usage, output and API may change at any time.
-Support is not ensured.
-
-## Installation
-
-You can install the benchmark tool via `npm install -g benchmark` for a global install, or without
-`-g` for a local install.
-Installing globally gives you access to the `benchmark` binary in your `PATH`.
-
-
-## CLI Usage
-
-Call the `benchmark` binary, followed by options, then double dash, then the command to benchmark.
-
-For more information on the available options, run `benchmark --help`:
-```
-$ benchmark --help
-[benchmark] benchmark [options] -- [command to benchmark]
-
-Collects process stats from running the command.
-
-Options:
-    --help                    Show this message.
-    (... other available options)
-
-Example:
-    benchmark --iterations=3 -- node my-script.js
-```
-
-
-## Example
-
-Given the naive implementation of a fibonacci number calculator below:
-```
-// fibonacci.js
-const fib = (n) => n > 1 ? fib(n - 1) + fib(n - 2) : n;
-console.log(fib(parseInt(process.argv[2])));
-```
-
-Run `benchmark -- node fibonacci.js 40` to benchmark calculating the 40th fibonacci number:
-
-```
-$ benchmark -- node fibonacci.js 40
-[benchmark] Benchmarking process over 5 iterations, with up to 5 retries.
-[benchmark]   node fibonacci.js 40 (at D:\sandbox\latest-project)
-[benchmark] Process Stats
-[benchmark]   Elapsed Time: 2365.40 ms (2449.00, 2444.00, 2357.00, 2312.00, 2265.00)
-[benchmark]   Average Process usage: 1.00 process(es) (1.00, 1.00, 1.00, 1.00, 1.00)
-[benchmark]   Peak Process usage: 1.00 process(es) (1.00, 1.00, 1.00, 1.00, 1.00)
-[benchmark]   Average CPU usage: 4.72 % (5.03, 4.86, 4.50, 4.50, 4.69)
-[benchmark]   Peak CPU usage: 23.40 % (25.00, 23.40, 21.80, 21.80, 25.00)
-[benchmark]   Average Memory usage: 22.34 MB (22.32, 22.34, 22.34, 22.35, 22.35)
-[benchmark]   Peak Memory usage: 22.34 MB (22.32, 22.34, 22.34, 22.35, 22.35)
-```
-
-## Example in watch mode
-
-`watch-script` accepts a node script when using the CLI. When using the API you can provide a `Command` instance. 
-
-```
-benchmark --verbose --watch-timeout 10000 --watch-matcher "Compiled successfully" --watch-script watch-script.js -- ng serve
-[benchmark] Benchmarking process over 5 iterations, with up to 5 retries.
-[benchmark]   ng serve (at D:\sandbox\latest-project)
-[benchmark] Process Stats
-[benchmark]   Elapsed Time: 470.40 ms (820.00, 557.00, 231.00, 509.00, 235.00)
-[benchmark]   Average Process usage: 2.00 process(es) (2.00, 2.00, 2.00, 2.00, 2.00)
-[benchmark]   Peak Process usage: 2.00 process(es) (2.00, 2.00, 2.00, 2.00, 2.00)
-[benchmark]   Average CPU usage: 33.77 % (31.27, 0.00, 101.70, 35.90, 0.00)
-[benchmark]   Peak CPU usage: 59.72 % (125.10, 0.00, 101.70, 71.80, 0.00)
-[benchmark]   Average Memory usage: 665.49 MB (619.84, 657.17, 669.47, 685.19, 695.76)
-[benchmark]   Peak Memory usage: 672.44 MB (639.87, 661.04, 669.47, 689.66, 702.14)
-```
-
-## API Usage
-
-You can also use the benchmarking API directly:
-
-```
-import { Command, defaultStatsCapture, runBenchmark } from '@angular-devkit/benchmark';
-
-const command = new Command('node', ['fibonacci.js', '40']);
-const captures = [defaultStatsCapture];
-
-runBenchmark({ command, command }).subscribe(results => {
-  // results is:[{
-  //   "name": "Process Stats",
-  //   "metrics": [{
-  //     "name": "Elapsed Time", "unit": "ms", "value": 1883.6,
-  //     "componentValues": [1733, 1957, 1580, 1763, 2385]
-  //   }, {
-  //     "name": "Average Process usage", "unit": "process(es)", "value": 1,
-  //     "componentValues": [1, 1, 1, 1, 1]
-  //   }, {
-  //     "name": "Peak Process usage", "unit": "process(es)", "value": 1,
-  //     "componentValues": [1, 1, 1, 1, 1]
-  //   }, {
-  //     "name": "Average CPU usage", "unit": "%", "value": 3.0855555555555556,
-  //     "componentValues": [1.9625, 1.9500000000000002, 1.9500000000000002, 4.887499999999999, 4.677777777777778]
-  //   }, {
-  //     "name": "Peak CPU usage", "unit": "%", "value": 19.380000000000003,
-  //     "componentValues": [15.7, 15.6, 15.6, 25, 25]
-  //   }, {
-  //     "name": "Average Memory usage", "unit": "MB", "value": 22.364057600000002,
-  //     "componentValues": [22.383104, 22.332416, 22.401024, 22.355968, 22.347776]
-  //   }, {
-  //     "name": "Peak Memory usage", "unit": "MB", "value": 22.3649792,
-  //     "componentValues": [22.384639999999997, 22.335487999999998, 22.401024, 22.355968, 22.347776]
-  //   }]
-  // }]
-});
-```
-
-A good example of API usage is the `main` binary itself, found in `./src/main.ts`.
-We recommend using TypeScript to get full access to the interfaces included.

-# Angular Build Optimizer
-
-Angular Build Optimizer contains Angular optimizations applicable to JavaScript code as a TypeScript transform pipeline.
-
-
-## Available optimizations
-
-Transformations applied depend on file content:
-
-- [Class fold](#class-fold), [Scrub file](#scrub-file) and [Prefix functions](#prefix-functions): applied to Angular apps and libraries.
-- [Import tslib](#import-tslib): applied when TypeScript helpers are found.
-
-Some of these optimizations add `/*@__PURE__*/` comments.
-These are used by JS optimization tools to identify pure functions that can potentially be dropped.
-
-
-### Class fold
-
-Static properties are folded into ES5 classes:
-
-```typescript
-// input
-var Clazz = (function () { function Clazz() { } return Clazz; }());
-Clazz.prop = 1;
-
-// output
-var Clazz = (function () { function Clazz() { } Clazz.prop = 1; return Clazz; }());
-```
-
-
-### Scrub file
-
-Angular decorators, property decorators and constructor parameters are removed, while leaving non-Angular ones intact.
-
-```typescript
-// input
-import { Injectable, Input, Component } from '@angular/core';
-import { NotInjectable, NotComponent, NotInput } from 'another-lib';
-var Clazz = (function () { function Clazz() { } return Clazz; }());
-Clazz.decorators = [{ type: Injectable }, { type: NotInjectable }];
-Clazz.propDecorators = { 'ngIf': [{ type: Input }] };
-Clazz.ctorParameters = function () { return [{type: Injector}]; };
-var ComponentClazz = (function () {
-  function ComponentClazz() { }
-  __decorate([
-    Input(),
-    __metadata("design:type", Object)
-  ], Clazz.prototype, "selected", void 0);
-  __decorate([
-    NotInput(),
-    __metadata("design:type", Object)
-  ], Clazz.prototype, "notSelected", void 0);
-  ComponentClazz = __decorate([
-    NotComponent(),
-    Component({
-        selector: 'app-root',
-        templateUrl: './app.component.html',
-        styleUrls: ['./app.component.css']
-    })
-  ], ComponentClazz);
-  return ComponentClazz;
-}());
-
-// output
-import { Injectable, Input, Component } from '@angular/core';
-import { NotInjectable, NotComponent } from 'another-lib';
-var Clazz = (function () { function Clazz() { } return Clazz; }());
-Clazz.decorators = [{ type: NotInjectable }];
-var ComponentClazz = (function () {
-  function ComponentClazz() { }
-  __decorate([
-    NotInput(),
-    __metadata("design:type", Object)
-  ], Clazz.prototype, "notSelected", void 0);
-  ComponentClazz = __decorate([
-    NotComponent()
-  ], ComponentClazz);
-  return ComponentClazz;
-}());
-```
-
-
-### Prefix functions
-
-Adds `/*@__PURE__*/` comments to top level downleveled class declarations and instantiation.
-
-Warning: this transform assumes the file is a pure module. It should not be used with unpure modules.
-
-```typescript
-// input
-var Clazz = (function () { function Clazz() { } return Clazz; }());
-var newClazz = new Clazz();
-var newClazzTwo = Clazz();
-
-// output
-var Clazz = /*@__PURE__*/ (function () { function Clazz() { } return Clazz; }());
-var newClazz = /*@__PURE__*/ new Clazz();
-var newClazzTwo = /*@__PURE__*/ Clazz();
-```
-
-
-### Prefix Classes
-
-Adds `/*@__PURE__*/` to downleveled TypeScript classes.
-
-```typescript
-// input
-var ReplayEvent = (function () {
-    function ReplayEvent(time, value) {
-        this.time = time;
-        this.value = value;
-    }
-    return ReplayEvent;
-}());
-
-// output
-var ReplayEvent = /*@__PURE__*/ (function () {
-    function ReplayEvent(time, value) {
-        this.time = time;
-        this.value = value;
-    }
-    return ReplayEvent;
-}());
-```
-
-
-### Import tslib
-
-TypeScript helpers (`__extends/__decorate/__metadata/__param`) are replaced with `tslib` imports whenever found.
-
-```typescript
-// input
-var __extends = (this && this.__extends) || function (d, b) {
-  for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
-  function __() { this.constructor = d; }
-  d.prototype = b === null ? Object.create(b) : (__.prototype = b.prototype, new __());
-};
-
-// output
-import { __extends } from "tslib";
-```
-
-### Wrap enums
-
-Wrap downleveled TypeScript enums in a function, and adds `/*@__PURE__*/` comment.
-
-```typescript
-// input
-var ChangeDetectionStrategy;
-(function (ChangeDetectionStrategy) {
-    ChangeDetectionStrategy[ChangeDetectionStrategy["OnPush"] = 0] = "OnPush";
-    ChangeDetectionStrategy[ChangeDetectionStrategy["Default"] = 1] = "Default";
-})(ChangeDetectionStrategy || (ChangeDetectionStrategy = {}));
-
-// output
-var ChangeDetectionStrategy = /*@__PURE__*/ (function () {
-  var ChangeDetectionStrategy = {};
-  ChangeDetectionStrategy[ChangeDetectionStrategy["OnPush"] = 0] = "OnPush";
-  ChangeDetectionStrategy[ChangeDetectionStrategy["Default"] = 1] = "Default";
-  return ChangeDetectionStrategy;
-})();
-```
-
-
-## Library Usage
-
-```typescript
-import { buildOptimizer } from '@angular-devkit/build-optimizer';
-
-const transpiledContent = buildOptimizer({ content: input }).content;
-```
-
-Available options:
-```typescript
-export interface BuildOptimizerOptions {
-  content?: string;
-  inputFilePath?: string;
-  outputFilePath?: string;
-  emitSourceMap?: boolean;
-  strict?: boolean;
-  isSideEffectFree?: boolean;
-}
-```
-
-
-## Webpack loader usage:
-
-```typescript
-import { BuildOptimizerWebpackPlugin } from '@angular-devkit/build-optimizer';
-
-module.exports = {
-  plugins: [
-    new BuildOptimizerWebpackPlugin(),
-  ]
-  module: {
-    rules: [
-      {
-        test: /\.js$/,
-        loader: '@angular-devkit/build-optimizer/webpack-loader',
-        options: {
-          sourceMap: false
-        }
-      }
-    ]
-  }
-}
-```
-
-
-## CLI usage
-
-```bash
-build-optimizer input.js
-build-optimizer input.js output.js
-```

-# Description
-
-Jobs is the Angular DevKit subsystem for scheduling and running generic functions with clearly 
-typed inputs and outputs. A `Job` instance is a function associated with metadata. You can
-schedule a job, synchronize it with other jobs, and use it to schedule other jobs.
-
-The whole API is serializable, allowing you to use a Node Stream or message channel to
-communicate between the job and the job scheduler.
-
-Jobs are lazy, cold, and guaranteed to execute exactly once when scheduled. Subscribing to a job
-returns messages from the point where the job is at.
-
-## Argument, Input, Output and Channels
-A job receives a single argument when scheduled and can also listen to an input channel. It can
-emit multiple outputs, and can also provide multiple output channels that emit asynchronous JSON 
-messages, which can be typed. 
-
-The I/O model is like that of an executable, where the argument corresponds to arguments on the 
-command line, the input channel to STDIN, the output channel to STDOUT, and the channels
-would be additional output streams.
-
-## LifeCycle
-A `Job` goes through multiple LifeCycle messages before its completion;
-1. `JobState.Queued`. The job was queued and is waiting. This is the default state from the
-    scheduler.
-1. `JobState.Ready`. The job's dependencies (see
-    ["Synchronizing and Dependencies"](#Dependencies)) are done running, the argument is 
-    validated, and the job is ready to execute.
-1. `JobState.Started`. The argument has been validated, the job has been called and is running. 
-    This is handled by the job itself (or `createJobHandler()`).
-1. `JobState.Ended`. The job has ended and is done running. This is handled by the job itself (or 
-    `createJobHandler()`).
-1. `JobState.Errored`. A unrecoverable error happened.
-
-Each state (except `Queued`) corresponds to a `JobOutboundMessage` on the `outboundBus` observable
-that triggers the state change. The `Scheduler` emits the `Ready` and `Errored` messages; the job 
-implementation should not emit them, and if it does they are filtered out. You can listen for 
-these messages or use the corresponding state member.
-
-The job implementation should emit the `Start` and `End` messages when it is starting the job logic
-itself. Only the first `Start` and `End` messages will be forwarded. Any more will be filtered out.
-
-The `Queued` state is set as the job is scheduled, so there is no need to listen for the message.
-
-## `Job<OutputType>` Object
-The `Job` object that is returned when you schedule a job provides access to the job's status and 
-utilities for tracking and modifying the job. 
-
-1. `id`. A unique symbol that can be used as a Map key.
-1. `description`. The description of the job from the scheduler. See `JobDescription` object.
-1. `argument`. The argument value that was used to start the job.
-1. `input`. An `Observer` that can be used to send validated inputs to the job itself.
-1. `output`. An `Observable<OutputType>` that filters out messages to get only the returned output
-    of a job.
-1. `promise`. A promise that waits for the last output of a job. Returns the last value outputted
-    (or no value if there's no last value).
-1. `state`. The current state of the job (see `LifeCycle`).
-1. `channels`. A map of side channels the user can listen to as `Observable`.
-1. `ping()`. A function that can be used to ping the job, receiving a `Promise` for when the ping
-    is answered.
-1. `stop()`. Sends a `stop` input to the job, which suggests to stop the job. The job itself can
-    choose to ignore this message.
-1. `inboundBus`. The raw input `Observer<JobInboundMessage>`. This can be used to send messages to
-    the `context.inboundBus` observable in the job. These are `JobInboundMessage` messages. See
-    ["Communicating With Jobs"](#Communicating).
-1. `outboundBus`. The raw output `Observable<JobOutput>`. This can be used to listen to messages
-    from the job. See ["Communicating With Jobs"](#Communicating).
-   
-## `JobHandlerContext<I, O>` Object
-The `JobHandlerContext<>` is passed to the job handler code in addition to its argument. The
-context contains the following members:
-
-1. `description`. The description of the job. Its name and schemas.
-1. `scheduler`. A `Scheduler<>` instance that can be used to create additional jobs.
-1. `dependencies`. A generic list of other job instances that were run as dependencies when
-    scheduling this job. Their `id` is not guaranteed to match the `id` of the `Job<>` instance 
-    itself (those `Job<>`s might just be proxies). The state of those `Job<>` is guaranteed to be
-    `JobState.Ended`, as `JobState.Errored` would have prevented this handler from running.
-1. `inboundBus`. The raw input observable, complement of the `inboundBus` observer from the `Job<>`.
-
-# Examples
-
-An example of a job that adds all input together and return the output value. We use a 
-simple synchronous job registry and a simple job scheduler.
-
-```typescript
-import { jobs } from '@angular-devkit/core';
-
-const add = jobs.createJobHandle<number[], number>(
-  input => input.reduce((total, curr) => total + curr, 0),
-);
-
-// Register the job in a SimpleJobRegistry. Different registries have different API.
-const registry = new jobs.SimpleJobRegistry();
-const scheduler = new jobs.SimpleScheduler(registry);
-registry.register(add, {
-  name: 'add',
-  input: { type: 'array', items: { type: 'number' } },
-  output: { type: 'number' },
-});
-
-scheduler.schedule('add', [1, 2, 3, 4]).promise
-  .then(output => console.log('1 + 2 + 3 + 4 is ' + output));
-```
-
-# Creating Jobs
-
-A job is at its core a function with a description object attached to it. The description object
-stores the JSON schemas used to validate the types of the argument passed in, the input and
-output values. By default, a job accepts and can output any JSON object.
-
-```typescript
-import { Observable } from 'rxjs';
-import { jobs } from '@angular-devkit/core';
-
-const argument = {
-  type: 'array', items: { type: 'number' },
-};
-const output = {
-  type: 'number',
-};
-
-export function add(argument: number[]): Observable<jobs.JobOutboundMessage<number>> {
-  return new Observable(o => {
-    o.next({ kind: jobs.JobOutboundMessageKind.Start });
-    o.next({
-      kind: jobs.JobOutboundMessageKind.Output,
-      output: argument.reduce((total, curr) => total + curr, 0),
-    });
-    o.next({ kind: jobs.JobOutboundMessageKind.End });
-    o.complete();
-  });
-}
-
-// Add a property to `add` to make it officially a JobHandler. The Job system does not recognize
-// any function as a JobHandler.
-add.jobDescription = {
-  argument: argument,
-  output: output,
-};
-
-// Call the job with an array as argument, and log its output.
-declare const scheduler: jobs.Scheduler;
-scheduler.schedule('add', [1, 2, 3, 4])
-    .output.subscribe(x => console.log(x));  // Will output 10.
-```
-
-This is a lot of boilerplate, so we made some helpers to improve readability and manage argument, 
-input and output automatically:
-
-```typescript
-// Add is a JobHandler function, like the above.
-export const add = jobs.createJobHandler<number[], number>(
-  argument => argument.reduce((total, curr) => total + curr, 0),
-);
-
-// Schedule like above.
-```
-
-You can also return a Promise or an Observable, as jobs are asynchronous. This helper will set
-start and end messages appropriately. It will also manage channels automatically (see below).
-
-A more complex job can be declared like this:
-
-```typescript
-import { Observable } from 'rxjs';
-import { jobs } from '@angular-devkit/core';
-
-// Show progress with each count in a separate output channel. Output "more" in a channel.
-export const count = jobs.createJobHandler<number, number>(
-  // Receive a context that contains additional methods to create channels.
-  (argument: number, { createChannel }) => new Observable<number>(o => {
-    const side = createChannel('side', { type: 'string', const: 'more' });
-    const progress = createChannel('progress', { type: 'number' });
-    let i = 0;
-    function doCount() {
-      o.next(i++);
-      progress.next(i / argument);
-      side.next('more');
-  
-      if (i < argument) {
-        setTimeout(doCount, 100);
-      } else {
-        o.complete();
-      }
-    }
-    setTimeout(doCount, 100);
-  }),
-  {
-    argument: { type: 'number' },
-    output: { type: 'number' },
-  },
-);
-
-// Get a hold of a scheduler that refers to the job above.
-declare const scheduler: jobs.Scheduler;
-
-const job = scheduler.schedule('count', 0);
-job.getChannel('side').subscribe(x => console.log(x));
-// You can type a channel too. Messages will be filtered out.
-job.getChannel<number>('progress', { type: 'number' }).subscribe(x => console.log(x));
-```
-
-## <a name="Communicating"></a>Communicating With Jobs
-Jobs can be started and updated in a separate process or thread, and as such communication with a 
-job should avoid using global objects (which might not be shared). The jobs API and schedulers
-provide 2 communication streams (one for input and the other for output), named `inboundBus` and 
-`outboundBus`.
-
-### Raw Input Stream
-The `schedule()` function returns a `Job<>` interface that contains a `inboundBus` member of type
-`Observer<JobInboundMessage>`. All messages sent _to_ the job goes through this stream. The `kind`
-member of the `JobInboundMessage` interface dictates what kind of message it is sending:
-
-1. `JobInboundMessageKind.Ping`. A simple message that should be answered with
-    `JobOutboundMessageKind.Pong` when the job is responsive. The `id` field of the message should
-    be used when returning `Pong`.
-1. `JobInboundMessageKind.Stop`. The job should be stopped. This is used when
-    cancelling/unsubscribing from the `output` (or by calling `stop()`). Any inputs or outputs
-    after this message will be ignored.
-1. `JobInboundMessageKind.Input` is used when sending inputs to a job. These correspond to the
-    `next` methods of an `Observer` and are reported to the job through its `context.input`
-    Observable. There is no way to communicate an error to the job.
-
-Using the `createJobHandler()` helper, all those messages are automatically handled by the
-boilerplate code. If you need direct access to raw inputs, you should subscribe to the
-`context.inboundBus` Observable.
-
-### Raw Output Stream
-The `Job<>` interface also contains a `outboundBus` member (of type
-`Observable<JobOutboundMessage<O>>` where `O` is the typed output of the job) which is the output
-complement of `inboundBus`. All messages sent _from_ the job goes through this stream. The `kind`
-member of the `JobOutboundMessage<O>` interface dictates what kind of message it is sending:
-
-1. `JobOutboundMessageKind.Create`. The `Job<>` was created, its dependencies are done, and the
-    library is validating Argument and calling the internal job code.
-1. `JobOutboundMessageKind.Start`. The job code itself should send that message when started.
-    `createJobHandler()` will do it automatically.
-1. `JobOutboundMessageKind.End`. The job has ended. This is done by the job itself and should always
-    be sent when completed. The scheduler will listen to this message to set the state and unblock
-    dependent jobs. `createJobHandler()` automatically send this message.
-1. `JobOutboundMessageKind.Pong`. The job should answer a `JobInboundMessageKind.Ping` message with
-    this. Automatically done by `createJobHandler()`.
-1. `JobOutboundMessageKind.Output`. An `Output` has been generated by the job.
-1. `JobOutboundMessageKind.ChannelMessage`, `JobOutboundMessageKind.ChannelError` and
-    `JobOutboundMessageKind.ChannelComplete` are used for output channels. These correspond to the
-    `next`, `error` and `complete` methods of an `Observer` and are available to the callee through
-    the `job.channels` map of Observable.
-
-Those messages can be accessed directly through the `job.outboundBus` member. The job itself should
-return an `Observable<JobOutboundMessage<O>>`. The `createJobHandler()` helper handles most of use
-cases of this and makes it easier for jobs to handle this.
-
-## Job Dispatchers
-Dispatchers are a helper that redirect to different jobs given conditions. To create a job 
-dispatcher, use the `createDispatcher()` function:
-
-```typescript
-import { jobs } from '@angular-devkit/core';
-
-// A dispatcher that installs node modules given a user's preference.
-const dispatcher = jobs.createDispatcher({
-  name: 'node-install',
-  argument: { properties: { moduleName: { type: 'string' } } },
-  output: { type: 'boolean' },
-});
-
-const npmInstall = jobs.createJobHandler(/* ... */, { name: 'npm-install' });
-const yarnInstall = jobs.createJobHandler(/* ... */, { name: 'yarn-install' });
-const pnpmInstall = jobs.createJobHandler(/* ... */, { name: 'pnpm-install' });
-
-declare const registry: jobs.SimpleJobRegistry;
-registry.register(dispatcher);
-registry.register(npmInstall);
-registry.register(yarnInstall);
-registry.register(pnpmInstall);
-
-// Default to npm.
-dispatcher.setDefaultDelegate(npmInstall.name);
-// If the user is asking for yarn over npm, uses it.
-dispatcher.addConditionalDelegate(() => userWantsYarn, yarnInstall.name);
-```
-
-## Execution Strategy
-Jobs are always run in parallel and will always start, but many helper functions are provided 
-when creating a job to help you control the execution strategy;
-
-1. `serialize()`. Multiple runs of this job will be queued with each others.
-1. `memoize(replayMessages = false)` will create a job, or reuse the same job  when inputs are 
-matching. If the inputs don't match, a new job will be started and its outputs will be stored.
-
-These strategies can be used when creating the job:
-
-```typescript
-// Same input and output as above.
-
-export const add = jobs.strategy.memoize()(
-  jobs.createJobHandler<number[], number>(
-      argument => argument.reduce((total, curr) => total + curr, 0),
-  ),
-);
-```
-
-Strategies can be reused to synchronize between jobs. For example, given jobs `jobA` and `jobB`, 
-you can reuse the strategy to serialize both jobs together;
-
-```typescript
-const strategy = jobs.strategy.serialize();
-const jobA = strategy(jobs.createJobHandler(...));
-const jobB = strategy(jobs.createJobHandler(...));
-```
-
-Even further, we can have package A and package B run in serialization, and B and C also be 
-serialized. Running A and C will run in parallel, while running B will wait for both A and C 
-to finish.
-
-```typescript
-const strategy1 = jobs.strategy.serialize();
-const strategy2 = jobs.strategy.serialize();
-const jobA = strategy1(jobs.createJobHandler(...));
-const jobB = strategy1(strategy2(jobs.createJobHandler(...)));
-const jobC = strategy2(jobs.createJobHandler(...));
-```
-
-# Scheduling Jobs
-Jobs can be scheduled using a `Scheduler` interface, which contains a `schedule()` method:
-
-```typescript
-interface Scheduler {
-  /**
-   * Schedule a job to be run, using its name.
-   * @param name The name of job to be run.
-   * @param argument The argument to send to the job when starting it.
-   * @param options Scheduling options.
-   * @returns The Job being run.
-   */
-  schedule<I extends MinimumInputValueT, O extends MinimumOutputValueT>(
-    name: JobName,
-    argument: I,
-    options?: ScheduleJobOptions,
-  ): Job<JsonValue, O>;
-}
-```
-
-The scheduler also has a `getDescription()` method to get a `JobDescription` object for a certain 
-name; that description contains schemas for the argument, input, output, and other channels:
-
-```typescript
-interface Scheduler {
-  /**
-   * Get a job description for a named job.
-   *
-   * @param name The name of the job.
-   * @returns A description, or null if the job cannot be scheduled.
-   */
-  getDescription(name: JobName): JobDescription | null;
-    
-  /**
-   * Returns true if the job name has been registered.
-   * @param name The name of the job.
-   * @returns True if the job exists, false otherwise.
-   */
-  has(name: JobName): boolean;
-}
-```
-
-Finally, the scheduler interface has a `pause()` method to stop scheduling. This will queue all 
-jobs and wait for the unpause function to be called before unblocking all the jobs scheduled. 
-This does not affect already running jobs.
-
-```typescript
-interface Scheduler {
-  /**
-   * Pause the scheduler, temporary queueing _new_ jobs. Returns a resume function that should be
-   * used to resume execution. If multiple `pause()` were called, all their resume functions must
-   * be called before the Scheduler actually starts new jobs. Additional calls to the same resume
-   * function will have no effect.
-   *
-   * Jobs already running are NOT paused. This is pausing the scheduler only.
-   *
-   * @returns A function that can be run to resume the scheduler. If multiple `pause()` calls
-   *          were made, all their return function must be called (in any order) before the
-   *          scheduler can resume.
-   */
-  pause(): () => void;
-}
-```
-
-## <a name="Dependencies"></a>Synchronizing and Dependencies
-When scheduling jobs, it is often necessary to run jobs after certain other jobs are finished. 
-This is done through the `dependencies` options in the `schedule()` method.
-
-These jobs will also be passed to the job being scheduled, through its context. This can be
-useful if, for example, the output of those jobs are of a known type, or have known side channels.
-
-An example of this would be a compiler that needs to know the output directory of other compilers
-before it, in a tool chain.
-
-### Dependencies
-When scheduling jobs, the user can add a `dependencies` field to the scheduling options. The
-scheduler will wait for those dependencies to finish before running the job, and pass those jobs 
-in the context of the job.
-
-### Accessing Dependencies
-Jobs are called with a `JobHandlerContext` as a second argument, which contains a
-`dependencies: Job<JsonValue>[]` member which contains all dependencies that were used when 
-scheduling the job. Those aren't fully typed as they are determined by the user, and not the job
-itself. They also can contain jobs that are not finished, and the job should use the `state`
-member of the job itself before trying to access its content.
-
-### Scheduler Sub Jobs
-The `JobHandlerContext` also contains a `scheduler` member which can be used to schedule jobs
-using the same scheduler that was used for the job. This allows jobs to call other jobs
-and wait for them to end.
-
-## Available Schedulers
-The Core Angular DevKit library provides 2 implementations for the `Scheduler` interface:
-
-## SimpleJobRegistry
-Available in the jobs namespace. A registry that accept job registration, and can also schedule
-jobs.
-
-```typescript
-import { jobs } from '@angular-devkit/core';
-
-const add = jobs.createJobHandler<number[], number>(
-  argument => argument.reduce((total, curr) => total + curr, 0),
-);
-
-// Register the job in a SimpleJobRegistry. Different registries have different API.
-const registry = new jobs.SimpleJobRegistry();
-const scheduler = new SimpleJobScheduler(registry);
-
-registry.register(add, {
-  name: 'add',
-  argument: { type: 'array', items: { type: 'number' } },
-  output: { type: 'number' },
-});
-
-scheduler.schedule('add', [1, 2, 3, 4]);
-```
-
-## NodeModuleJobRegistry
-Available through `@angular-devkit/core/node`.
-
-A scheduler that loads jobs using their node package names. These jobs need to use the
-`createJobHandler()` helper and report their argument/input/output schemas that way.
-
-```typescript
-declare const registry: NodeModuleJobRegistry;
-const scheduler = new SimpleJobScheduler(registry);
-
-scheduler.schedule('some-node-package#someExport', 'input');
-```
-
-# Gotchas
-
-1. Deadlocking Dependencies  
-   It is impossible to add dependencies to an already running job, but it is entirely possible to 
-   get locked between jobs. Be aware of your own dependencies.
-
-1. Using `job.promise`  
-    `job.promise` waits for the job to ends. Don't rely on it unless you know the job is not 
-    watching and running for a long time. If you aren't sure, use
-    `job.output.pipe(first()).toPromise()` instead which will return the first next output, 
-    regardless of whether the job watches and rerun or not.
-
-
-# FAQ
-
-1. Laziness  
-    A job is lazy until executed, but its messages will be replayed when resubscribed.
-
-1. Serialize Strategy vs Dependencies  
-    Strategies are functions that transform the execution of a job, and can be used when
-    declaring the job, or registering it. Dependencies, on the other hand, are listed when
-    scheduling a job to order jobs during scheduling.
-    
-    A job has no control over the way it's scheduled, and its dependencies. It can, however,
-    declare that it shouldn't run at the same time as itself. Alternatively, a user could
-    schedule a job twice and imply that the second run should wait for the first to finish. In
-    practice, this would be equivalent to having the job be serialized, but the important detail 
-    is in _whom_ is defining the rules; using the `serialize()` strategy, the job implementation
-    is, while when using dependencies, the user is.
-    
-    The user does not need to know how to job needs to synchronize with itself, and the job does
-    not need to know how it synchronizes with other jobs that it doesn't know about. That's part 
-    of the strength of this system as every job can be developed in a vacuum, only caring about
-    its contracts (argument, input and output) and its own synchronization.

-* Added check for `env.MSYSTEM` in windows case, see https://github.com/angular/angular-cli/commit/b8d4e19fc4209ff6a52b6e6a151927f6fe34b60e
-* require the locally vendored has-flag rather than npm package
-* support browser runtimes by mocking out the process object if it doesn't exist

 # Schematics
+
 > A scaffolding library for the modern web.
 
 ## Description
+
 Schematics are generators that transform an existing filesystem. They can create files, refactor existing files, or move files around.
 
 What distinguishes Schematics from other generators, such as Yeoman or Yarn Create, is that schematics are purely descriptive; no changes are applied to the actual filesystem until everything is ready to be committed. There is no side effect, by design, in Schematics.
 
 # Glossary
 
-| Term | Description |
-|------|-------------|
-| **Schematics** | A generator that executes descriptive code without side effects on an existing file system. |
-| **Collection** | A list of schematics metadata. Schematics can be referred by name inside a collection. |
-| **Tool**       | The code using the Schematics library. |
-| **Tree**       | A staging area for changes, containing the original file system, and a list of changes to apply to it. |
-| **Rule**       | A function that applies actions to a `Tree`. It returns a new `Tree` that will contain all transformations to be applied. |
-| **Source**     | A function that creates an entirely new `Tree` from an empty filesystem. For example, a file source could read files from disk and create a Create Action for each of those.
-| **Action**     | An atomic operation to be validated and committed to a filesystem or a `Tree`. Actions are created by schematics. |
-| **Sink**       | The final destination of all `Action`s. |

 # Tooling
-Schematics is a library, and does not work by itself. A [reference CLI](https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/schematics_cli/bin/schematics.ts) is available on this repository, and is published on NPM at [@angular-devkit/schematics-cli](https://www.npmjs.com/package/@angular-devkit/schematics-cli).

This document explains the library usage and the tooling API, but does not go into the tool implementation itself.
 
 The tooling is responsible for the following tasks:
 
 1. Create the Schematic Engine, and pass in a Collection and Schematic loader.
 1. Understand and respect the Schematics metadata and dependencies between collections. Schematics can refer to dependencies, and it's the responsibility of the tool to honor those dependencies. The reference CLI uses NPM packages for its collections.
 1. Create the Options object. Options can be anything, but the schematics can specify a JSON Schema that should be respected. The reference CLI, for example, parses the arguments as a JSON object and validates it with the Schema specified by the collection.
-  1. Schematics provides some JSON Schema formats for validation that tooling should add. These validate paths, html selectors and app names. Please check the reference CLI for how these can be added.

 1. Call the schematics with the original Tree. The tree should represent the initial state of the filesystem. The reference CLI uses the current directory for this.
 1. Create a Sink and commit the result of the schematics to the Sink. Many sinks are provided by the library; FileSystemSink and DryRunSink are examples.
 1. Output any logs propagated by the library, including debugging information.

 The tooling API is composed of the following pieces:
 
 ## Engine
+
 The `SchematicEngine` is responsible for loading and constructing `Collection`s and `Schematics`. When creating an engine, the tooling provides an `EngineHost` interface that understands how to create a `CollectionDescription` from a name, and how to create a `SchematicDescription`.
 
 # Schematics (Generators)
+
 Schematics are generators and part of a `Collection`.
 
 ## Collection
+
 A Collection is defined by a `collection.json` file (in the reference CLI). This JSON defines the following properties:
 
-| Prop Name | Type | Description |
-|---|---|---|
-| **name** | `string` | The name of the collection. |

 # Operators, Sources and Rules
+
 A `Source` is a generator of a `Tree`; it creates an entirely new root tree from nothing. A `Rule` is a transformation from one `Tree` to another. A `Schematic` (at the root) is a `Rule` that is normally applied on the filesystem.
 
 ## Operators
+
 `FileOperator`s apply changes to a single `FileEntry` and return a new `FileEntry`. The result follows these rules:

 # Templating
+
 As referenced above, some functions are based upon a file templating system, which consists of path and content templating.
 
 The system operates on placeholders defined inside files or their paths as loaded in the `Tree` and fills these in as defined in the following, using values passed into the `Rule` which applies the templating (i.e. `template<T>(options: T)`).

 1. Then the `template` `Rule` fills in the specified templating placeholders. For this, it only knows about the variables and functions passed to it via the options-object.
 1. Finally, the resulting `Tree`, containing the new file, is merged with the existing files of the project which the Schematic is run on.

-# Future Work
-Schematics is not done yet. Here's a list of things we are considering:
-
-* Smart defaults for Options. Having a JavaScript function for default values based on other default values.
-* Prompt for input options. This should only be prompted for the original schematics, dependencies to other schematics should not trigger another prompting.
-* Tasks for running tooling-specific jobs before and after a schematics has been scaffolded. Such tasks can involve initialize git, or npm install. A specific list of tasks should be provided by the tool, with unsupported tasks generating an error.

+# Schematics CLI
+
+This package contains the executable for running a [Schematic](/packages/angular_devkit/schematics/README.md).
+
+# Usage
+
+```
+$ schematics [CollectionName:]SchematicName [options, ...]
+
+By default, if the collection name is not specified, use the internal collection provided
+by the Schematics CLI.
+
+Options:
+    --debug             Debug mode. This is true by default if the collection is a relative
+                        path (in that case, turn off with --debug=false).
+
+    --allow-private     Allow private schematics to be run from the command line. Default to
+                        false.
+
+    --dry-run           Do not output anything, but instead just show what actions would be
+                        performed. Default to true if debug is also true.
+
+    --force             Force overwriting files that would otherwise be an error.
+
+    --list-schematics   List all schematics from the collection, by name. A collection name
+                        should be suffixed by a colon. Example: '@angular-devkit/schematics-cli:'.
+
+    --no-interactive    Disables interactive input prompts.
+
+    --verbose           Show more information.
+
+    --help              Show this message.
+
+Any additional option is passed to the Schematics depending on its schema.
+```
+
+# Examples
+
+1. Create a new NPM package that contains a blank schematic.
+
+```sh
+$ schematics blank <name>
+```
+
+2. Walkthrough example that demonstrates how to build a schematic.
+
+```sh
+$ schematics schematic --name <name>
+```

+# Getting Started With Schematics
+
+This repository is a basic Schematic implementation that serves as a starting point to create and publish Schematics to NPM.
+
+### Testing
+
+To test locally, install `@angular-devkit/schematics-cli` globally and use the `schematics` command line tool. That tool acts the same as the `generate` command of the Angular CLI, but also has a debug mode.
+
+Check the documentation with
+
+```bash
+schematics --help
+```
+
+### Unit Testing
+
+`npm run test` will run the unit tests, using Jasmine as a runner and test framework.
+
+### Publishing
+
+To publish, simply do:
+
+```bash
+npm run build
+npm publish
+```
+
+That's it!

+To test locally, install `@angular-devkit/schematics-cli` globally and use the `schematics` command line tool. That tool acts the same as the `generate` command of the Angular CLI, but also has a debug mode.
+
+Check the documentation with
+
+```bash
+schematics --help
+```
+
+### Unit Testing
+
+`npm run test` will run the unit tests, using Jasmine as a runner and test framework.
+
+### Publishing
+
+To publish, simply do:
+
+```bash
+npm run build
+npm publish
+```
+
+That's it!

-# Angular Ahead-of-Time Webpack Plugin
+# Angular Compiler Webpack Plugin
 
-Webpack 4.0 plugin that AoT compiles your Angular components and modules.
+Webpack 5.x plugin for the Angular Ahead-of-Time compiler. The plugin also supports Angular JIT mode.
+When this plugin is used outside of the Angular CLI, the Ivy linker will also be needed to support
+the usage of Angular libraries. An example configuration of the Babel-based Ivy linker is provided
+in the linker section. For additional information regarding the linker, please see: https://angular.dev/tools/libraries/creating-libraries#consuming-partial-ivy-code-outside-the-angular-cli
 
 ## Usage
 
 In your webpack config, add the following plugin and loader.
 
-Angular version 5 and up, use `AngularCompilerPlugin`:
-
 ```typescript
-import { AngularCompilerPlugin } from '@ngtools/webpack';
+import { AngularWebpackPlugin } from '@ngtools/webpack';
 
-exports = { /* ... */
+exports = {
+  /* ... */
   module: {
     rules: [
+      /* ... */
       {
-        test: /(?:\.ngfactory\.js|\.ngstyle\.js|\.ts)$/,
-        loader: '@ngtools/webpack'
-      }
-    ]
+        test: /\.[jt]sx?$/,
+        loader: '@ngtools/webpack',
+      },
+    ],
   },
 
   plugins: [
-    new AngularCompilerPlugin({
-      tsConfigPath: 'path/to/tsconfig.json',
-      entryModule: 'path/to/app.module#AppModule',
-      sourceMap: true,
-      i18nInFile: 'path/to/translations.en.xlf',
-      i18nInFormat: 'xlf',
-      i18nOutFile: 'path/to/translations.xlf',
-      i18nOutFormat: 'xlf',
-      locale: 'en',
-      hostReplacementPaths: {
-        'path/to/config.development.ts': 'path/to/config.production.ts'
-      }
-    })
-  ]
+    new AngularWebpackPlugin({
+      tsconfig: 'path/to/tsconfig.json',
+      // ... other options as needed
+    }),
+  ],
 };
 ```
 
-The loader works with webpack plugin to compile your TypeScript. It's important to include both, and to not include any other TypeScript compiler loader.
+The loader works with webpack plugin to compile the application's TypeScript. It is important to include both, and to not include any other TypeScript loader.
 
 ## Options
 
-* `tsConfigPath`. The path to the `tsconfig.json` file. This is required. In your `tsconfig.json`, you can pass options to the Angular Compiler with `angularCompilerOptions`.
-* `basePath`. Optional. The root to use by the compiler to resolve file paths. By default, use the `tsConfigPath` root.
-* `entryModule`. Optional if specified in `angularCompilerOptions`. The path and class name of the main application module. This follows the format `path/to/file#ClassName`.
-* `mainPath`. Optional if `entryModule` is specified. The `main.ts` file containing the bootstrap code. The plugin will use AST to determine the `entryModule`.
-* `skipCodeGeneration`. Optional, defaults to `false`. Disable code generation and do not refactor the code to bootstrap. This replaces `templateUrl: "string"` with `template: require("string")` (and similar for styles) to allow for webpack to properly link the resources.
-* `sourceMap`. Optional. Include sourcemaps.
-* `compilerOptions`. Optional. Override options in `tsconfig.json`.
-* `contextElementDependencyConstructor`. Optional. Set to `require('webpack/lib/dependencies/ContextElementDependency')` if you are having `No module factory available for dependency type: ContextElementDependency` errors.
-* `directTemplateLoading`. Optional. It causes the plugin to load component templates (HTML) directly from the filesystem.  This is more efficient if only using the `raw-loader` to load component templates.  Do not enable this option if additional loaders are configured for component templates.
-* `forkTypeChecker`. Optional, defaults to `true`. Run the TypeScript type checker in a forked process.
-* `hostReplacementPaths`. Optional. It allows replacing resources with other resources in the build.
-* `platform`. Optional, defaults to `0`. Possible values are `0` and `1`. `0` stands for browser and `1` for server.
-* `logger`. Optional. A custom logger that sends information to STDOUT and STDERR.
-* `nameLazyFiles`. Optional. If `true` then uses the `[request]` placeholder to set dynamic chunk names.
-* `missingTranslation`. Optional and only used for View Engine compilations. defaults to `warning`. Possible values are `warning`, `error` or `ignore`. Determines how to handle missing translations for i18n.
-* `i18nInFile`. Optional and only used for View Engine compilations. Localization file to use for i18n.
-* `i18nInFormat`. Optional and only used for View Engine compilations. The format of the localization file.
-* `i18nOutFile`. Optional and only used for View Engine compilations. The name of the file to write extractions to.
-* `i18nOutFormat`. Optional and only used for View Engine compilations. The format of the localization file where extractions will be written to.
-* `locale`. Optional and only used for View Engine compilations. Locale to use for i18n.
+- `tsconfig` [default: `tsconfig.json`] - The path to the application's TypeScript Configuration file. In the `tsconfig.json`, you can pass options to the Angular Compiler with `angularCompilerOptions`. Relative paths will be resolved from the Webpack compilation's context.
+- `compilerOptions` [default: none] - Overrides options in the application's TypeScript Configuration file (`tsconfig.json`).
+- `jitMode` [default: `false`] - Enables JIT compilation and do not refactor the code to bootstrap. This replaces `templateUrl: "string"` with `template: require("string")` (and similar for styles) to allow for webpack to properly link the resources.
+- `directTemplateLoading` [default: `true`] - Causes the plugin to load component templates (HTML) directly from the filesystem. This is more efficient if only using the `raw-loader` to load component templates. Do not enable this option if additional loaders are configured for component templates.
+- `fileReplacements` [default: none] - Allows replacing TypeScript files with other TypeScript files in the build. This option acts on fully resolved file paths.
+- `inlineStyleFileExtension` [default: none] - When set inline component styles will be processed by Webpack as files with the provided extension.

+## Ivy Linker
 
-## Features
-The benefits and ability of using [`@ngtools/webpack`](https://www.npmjs.com/~ngtools) standalone from the Angular CLI as presented in [Stephen Fluin's Angular CLI talk](https://youtu.be/uBRK6cTr4Vk?t=6m45s) at Angular Connect 2016:
+The Ivy linker can be setup by using the Webpack `babel-loader` package.
+If not already installed, add the `babel-loader` package using your project's package manager.
+Then in your webpack config, add the `babel-loader` with the following configuration.
+If the `babel-loader` is already present in your configuration, the linker plugin can be added to
+the existing loader configuration as well.
+Enabling caching for the `babel-loader` is recommended to avoid reprocessing libraries on
+every build.
+For additional information regarding the `babel-loader` package, please see: https://github.com/babel/babel-loader/tree/main#readme
 
-* Compiles Sass/Less into CSS
-* TypeScript transpilation
-* Bundles JavaScript, CSS
-* Asset optimization
-* Virtual filesystem for assets
-* For serving local assets and compile versions.
-* Live-reload via websockets
-* Code splitting
-* Recognizing the use of `loadChildren` in the router, and bundling those modules separately so that any dependencies of those modules are not going to be loaded as part of your main bundle. These separate bundles will be pulled out of the critical path of your application, making your total application bundle much smaller and loading it much more performant.

-An app shell lets Universal render a portion of your application via a route at build time.
-This gives users a meaningful first paint of your application that appears quickly
-because the browser can simply render the HTML without the need to initialize any JavaScript.
-
-Use this command with a routing app that is accompanied by a Universal server-side app.
-
-To create an app shell, use the following command.
-
-<code-example format="." language="bash">
- ng generate app-shell --client-project my-app --universal-project server-app
-</code-example>
-
-* `my-app` is the name of your client application
-* `server-app` is the name of the Universal (server) application
-
-The command adds two new architect build targets to your `angular.json` configuration file (along with a few other changes).
-
-<code-example  format="." language="none" linenums="false">
-"server": {
-  "builder": "@angular-devkit/build-angular:server",
-  "options": {
-    "outputPath": "dist/my-app-server",
-    "main": "src/main.server.ts",
-    "tsConfig": "src/tsconfig.server.json"
-  }
-},
-"app-shell": {
-  "builder": "@angular-devkit/build-angular:app-shell",
-  "options": {
-    "browserTarget": "my-app:build",
-    "serverTarget": "my-app:server",
-    "route": "shell"
-  }
-}
-</code-example>
-
-To verify the that the app has been built with the default shell content:
-
-1. Run the app-shell target.
-
-   <code-example format="." language="bash">
-       ng run my-app:app-shell
-    </code-example>
-
-1. Open `dist/app-shell/index.html` in your browser.
-
-The default text "app-shell works!" verifies that the app-shell route was rendered as part of the output.

 # <%= classify(name) %>
 
-This library was generated with [Angular CLI](https://github.com/angular/angular-cli) version <%= angularLatestVersion %>.
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version <%= angularLatestVersion %>.
 
 ## Code scaffolding
 
-Run `ng generate component component-name --project <%= name %>` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module --project <%= name %>`.
-> Note: Don't forget to add `--project <%= name %>` or else it will be added to the default project in your `angular.json` file. 
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
 
-## Build
+```bash
+ng generate component component-name
+```
 
-Run `ng build <%= name %>` to build the project. The build artifacts will be stored in the `dist/` directory.
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
 
-## Publishing
+```bash
+ng generate --help
+```
 
-After building your library with `ng build <%= name %>`, go to the dist folder `cd dist/<%= dasherize(name) %>` and run `npm publish`.
+## Building
+
+To build the library, run:
+
+```bash
+ng build <%= name %>
+```
+
+This command will compile your project, and the build artifacts will be placed in the `dist/` directory.
+
+### Publishing the Library
+
+Once the project is built, you can publish your library by following these steps:
+
+1. Navigate to the `dist` directory:
+   ```bash
+   cd dist/<%= dasherize(name) %>
+   ```
+
+2. Run the `npm publish` command to publish your library to the npm registry:
+   ```bash
+   npm publish
+   ```
 
 ## Running unit tests
 
-Run `ng test <%= name %>` to execute the unit tests via [Karma](https://karma-runner.github.io).
+To execute unit tests with the [Karma](https://karma-runner.github.io) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
 
-## Further help
+## Additional Resources
 
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

-        // Note: 'allowIn' and 'allowYield' track 1:1 with the [in] and [yield] concepts in the ES6
-        // grammar specification.
-        //
-        // An important thing about these context concepts.  By default they are effectively inherited
-        // while parsing through every grammar production.  i.e. if you don't change them, then when
-        // you parse a sub-production, it will have the same context values as the parent production.
-        // This is great most of the time.  After all, consider all the 'expression' grammar productions
-        // and how nearly all of them pass along the 'in' and 'yield' context values:
-        //
-        // EqualityExpression[In, Yield] :
-        //      RelationalExpression[?In, ?Yield]
-        //      EqualityExpression[?In, ?Yield] == RelationalExpression[?In, ?Yield]

-        //      EqualityExpression[?In, ?Yield] !== RelationalExpression[?In, ?Yield]
-        //
-        // Where you have to be careful is then understanding what the points are in the grammar
-        // where the values are *not* passed along.  For example:
-        //
-        // SingleNameBinding[Yield,GeneratorParameter]
-        //      [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt
-        //      [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt
-        //
-        // Here this is saying that if the GeneratorParameter context flag is set, that we should
-        // explicitly set the 'yield' context flag to false before calling into the BindingIdentifier
-        // and we should explicitly unset the 'yield' context flag before calling into the Initializer.
-        // production.  Conversely, if the GeneratorParameter context flag is not set, then we
-        // should leave the 'yield' context flag alone.
-        //
-        // Getting this all correct is tricky and requires careful reading of the grammar to
-        // understand when these values should be changed versus when they should be inherited.
-        //
-        // Note: it should not be necessary to save/restore these flags during speculative/lookahead
-        // parsing.  These context flags are naturally stored and restored through normal recursive
-        // descent parsing and unwinding.

-     * Any module resolution kind can be augmented with optional settings: 'baseUrl', 'paths' and 'rootDirs' - they are used to
-     * mitigate differences between design time structure of the project and its runtime counterpart so the same import name
-     * can be resolved successfully by TypeScript compiler and runtime module loader.
-     * If these settings are set then loading procedure will try to use them to resolve module name and it can of failure it will
-     * fallback to standard resolution routine.
-     *
-     * - baseUrl - this setting controls how non-relative module names are resolved. If this setting is specified then non-relative
-     * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will
-     * be '/a/b/c/d'
-     * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names
-     * will be resolved based on the content of the module name.
-     * Structure of 'paths' compiler options
-     * 'paths': {
-     *    pattern-1: [...substitutions],
-     *    pattern-2: [...substitutions],
-     *    ...
-     *    pattern-n: [...substitutions]
-     * }
-     * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against
-     * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case.
-     * If pattern contains '*' then to match pattern "<prefix>*<suffix>" module name must start with the <prefix> and end with <suffix>.
-     * <MatchedStar> denotes part of the module name between <prefix> and <suffix>.
-     * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked.
-     * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module
-     * from the candidate location.
-     * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every
-     * substitution in the list and replace '*' with <MatchedStar> string. If candidate location is not rooted it
-     * will be converted to absolute using baseUrl.
-     * For example:
-     * baseUrl: /a/b/c
-     * "paths": {
-     *     // match all module names
-     *     "*": [
-     *         "*",        // use matched name as is,
-     *                     // <matched name> will be looked as /a/b/c/<matched name>
-     *
-     *         "folder1/*" // substitution will convert matched name to 'folder1/<matched name>',
-     *                     // since it is not rooted then final candidate location will be /a/b/c/folder1/<matched name>
-     *     ],
-     *     // match module names that start with 'components/'
-     *     "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/<matched name> to '/root/components/folder1/<matched name>',
-     *                                              // it is rooted so it will be final candidate location
-     * }
-     *
-     * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if
-     * they were in the same location. For example lets say there are two files
-     * '/local/src/content/file1.ts'
-     * '/shared/components/contracts/src/content/protocols/file2.ts'
-     * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so
-     * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime.
-     * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all
-     * root dirs were merged together.
-     * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].
-     * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file:
-     * '/local/src/content/protocols/file2' and try to load it - failure.
-     * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will
-     * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining
-     * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.

-// Transforms generator functions into a compatible ES5 representation with similar runtime
-// semantics. This is accomplished by first transforming the body of each generator
-// function into an intermediate representation that is the compiled into a JavaScript
-// switch statement.
-//
-// Many functions in this transformer will contain comments indicating the expected
-// intermediate representation. For illustrative purposes, the following intermediate
-// language is used to define this intermediate representation:
-//
-//  .nop                            - Performs no operation.
-//  .local NAME, ...                - Define local variable declarations.
-//  .mark LABEL                     - Mark the location of a label.
-//  .br LABEL                       - Jump to a label. If jumping out of a protected
-//                                    region, all .finally blocks are executed.
-//  .brtrue LABEL, (x)              - Jump to a label IIF the expression `x` is truthy.
-//                                    If jumping out of a protected region, all .finally
-//                                    blocks are executed.
-//  .brfalse LABEL, (x)             - Jump to a label IIF the expression `x` is falsey.
-//                                    If jumping out of a protected region, all .finally
-//                                    blocks are executed.
-//  .yield (x)                      - Yield the value of the optional expression `x`.
-//                                    Resume at the next label.
-//  .yieldstar (x)                  - Delegate yield to the value of the optional
-//                                    expression `x`. Resume at the next label.
-//                                    NOTE: `x` must be an Iterator, not an Iterable.
-//  .loop CONTINUE, BREAK           - Marks the beginning of a loop. Any "continue" or
-//                                    "break" abrupt completions jump to the CONTINUE or
-//                                    BREAK labels, respectively.
-//  .endloop                        - Marks the end of a loop.
-//  .with (x)                       - Marks the beginning of a WithStatement block, using
-//                                    the supplied expression.
-//  .endwith                        - Marks the end of a WithStatement.
-//  .switch                         - Marks the beginning of a SwitchStatement.
-//  .endswitch                      - Marks the end of a SwitchStatement.
-//  .labeled NAME                   - Marks the beginning of a LabeledStatement with the
-//                                    supplied name.
-//  .endlabeled                     - Marks the end of a LabeledStatement.
-//  .try TRY, CATCH, FINALLY, END   - Marks the beginning of a protected region, and the
-//                                    labels for each block.
-//  .catch (x)                      - Marks the beginning of a catch block.
-//  .finally                        - Marks the beginning of a finally block.
-//  .endfinally                     - Marks the end of a finally block.
-//  .endtry                         - Marks the end of a protected region.
-//  .throw (x)                      - Throws the value of the expression `x`.
-//  .return (x)                     - Returns the value of the expression `x`.
-//
-// In addition, the illustrative intermediate representation introduces some special
-// variables:
-//
-//  %sent%                          - Either returns the next value sent to the generator,
-//                                    returns the result of a delegated yield, or throws
-//                                    the exception sent to the generator.
-//  %error%                         - Returns the value of the current exception in a
-//                                    catch block.
-//
-// This intermediate representation is then compiled into JavaScript syntax. The resulting
-// compilation output looks something like the following:
-//
-//  function f() {
-//      var /*locals*/;
-//      /*functions*/
-//      return __generator(function (state) {
-//          switch (state.label) {
-//              /*cases per label*/
-//          }
-//      });
-//  }
-//
-// Each of the above instructions corresponds to JavaScript emit similar to the following:
-//
-//  .local NAME                   | var NAME;
-// -------------------------------|----------------------------------------------

-    //            label  - The next point at which to resume evaluation of the generator body.
-    //            trys   - A stack of protected regions (try/catch/finally blocks).
-    //            ops    - A stack of pending instructions when inside of a finally block.
-    //  f       A value indicating whether the generator is executing.
-    //  y       An iterator to delegate for a yield*.
-    //  t       A temporary variable that holds one of the following values (note that these
-    //          cases do not overlap):
-    //          - The completion value when resuming from a `yield` or `yield*`.
-    //          - The error value for a catch block.
-    //          - The current protected region (array of try/catch/finally/end labels).
-    //          - The verb (`next`, `throw`, or `return` method) to delegate to the expression
-    //            of a `yield*`.
-    //          - The result of evaluating the verb delegated to the expression of a `yield*`.
-    //
-    // functions:
-    //  verb(n)     Creates a bound callback to the `step` function for opcode `n`.
-    //  step(op)    Evaluates opcodes in a generator body until execution is suspended or
-    //              completed.
-    //
-    // The __generator helper understands a limited set of instructions:
-    //  0: next(value?)     - Start or resume the generator with the specified value.
-    //  1: throw(error)     - Resume the generator with an exception. If the generator is
-    //                        suspended inside of one or more protected regions, evaluates
-    //                        any intervening finally blocks between the current label and
-    //                        the nearest catch block or function boundary. If uncaught, the
-    //                        exception is thrown to the caller.
-    //  2: return(value?)   - Resume the generator as if with a return. If the generator is
-    //                        suspended inside of one or more protected regions, evaluates any
-    //                        intervening finally blocks.
-    //  3: break(label)     - Jump to the specified label. If the label is outside of the
-    //                        current protected region, evaluates any intervening finally
-    //                        blocks.
-    //  4: yield(value?)    - Yield execution to the caller with an optional value. When
-    //                        resumed, the generator will continue at the next label.
-    //  5: yield*(value)    - Delegates evaluation to the supplied iterator. When
-    //                        delegation completes, the generator will continue at the next
-    //                        label.
-    //  6: catch(error)     - Handles an exception thrown from within the generator body. If
-    //                        the current label is inside of one or more protected regions,
-    //                        evaluates any intervening finally blocks between the current
-    //                        label and the nearest catch block or function boundary. If
-    //                        uncaught, the exception is thrown to the caller.
-    //  7: endfinally       - Ends a finally block, resuming the last instruction prior to
-    //                        entering a finally block.

-             * ```js

-             * |   **Bucket A**   |      |    **Bucket B**      |      |    **Bucket C**   |
-             * |    Symbols to    |      | Aliases to symbols   |      | Symbols to return |
-             * |    definitely    |      | in Buckets A or C    |      | if nothing better |
-             * |      return      |      | (don’t return these) |      |    comes along    |
-             * |__________________|      |______________________|      |___________________|
-             * ```
-             *
-             * We _probably_ want to show `foo` from 'x', but not from 'y' or 'z'. However, if 'x' is not in a package.json, it
-             * will not appear in a `forEachExternalModuleToImportFrom` iteration. Furthermore, the order of iterations is not
-             * guaranteed, as it is host-dependent. Therefore, when presented with the symbol `foo` from module 'y' alone, we
-             * may not be sure whether or not it should go in the list. So, we’ll take the following steps:
-             *
-             * 1. Resolve alias `foo` from 'y' to the export declaration in 'x', get the symbol there, and see if that symbol is
-             *    already in Bucket A (symbols we already know will be returned). If it is, put `foo` from 'y' in Bucket B
-             *    (symbols that are aliases to symbols in Bucket A). If it’s not, put it in Bucket C.
-             * 2. Next, imagine we see `foo` from module 'z'. Again, we resolve the alias to the nearest export, which is in 'y'.
-             *    At this point, if that nearest export from 'y' is in _any_ of the three buckets, we know the symbol in 'z'
-             *    should never be returned in the final list, so put it in Bucket B.
-             * 3. Next, imagine we see `foo` from module 'x', the original. Syntactically, it doesn’t look like a re-export, so
-             *    we can just check Bucket C to see if we put any aliases to the original in there. If they exist, throw them out.
-             *    Put this symbol in Bucket A.
-             * 4. After we’ve iterated through every symbol of every module, any symbol left in Bucket C means that step 3 didn’t
-             *    occur for that symbol---that is, the original symbol is not in Bucket A, so we should include the alias. Move
-             *    everything from Bucket C to Bucket A.

-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version <%= version %>.
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version <%= version %>.
 
 ## Development server
 
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+To start a local development server, run:
+
+```bash
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
 
 ## Code scaffolding
 
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
 
-## Build
+## Building
 
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
+To build the project run:
+
+```bash
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
 
 ## Running unit tests
 
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+To execute unit tests with the [Karma](https://karma-runner.github.io) test runner, use the following command:
+
+```bash
+ng test
+```
 
 ## Running end-to-end tests
 
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
 
-## Further help
+## Additional Resources
 
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

-# Getting Started With Schematics
-
-This repository is a basic Schematic implementation that serves as a starting point to create and publish Schematics to NPM.
-
-### Testing
-
-To test locally, install `@angular-devkit/schematics-cli` globally and use the `schematics` command line tool. That tool acts the same as the `generate` command of the Angular CLI, but also has a debug mode.
-
-Check the documentation with
-```bash
-schematics --help
-```
-
-### Unit Testing
-
-`npm run test` will run the unit tests, using Jasmine as a runner and test framework.
-
-### Publishing
-
-To publish, simply do:
-
-```bash
-npm run build
-npm publish
-```
-
-That's it!

 ## <a name="public-api"></a> Updating the Public API
-Our Public API is protected with TS API Guardian. This is a tool that keeps track of public API surface of our packages.
-
-To test if your change effect the public API you need to run the API guardian on that particular package.
-
-For example in case `@angular-devkit/core` package was modified you need to run:
-
-```bash
-yarn bazel test //etc/api:angular_devkit_core_api
-```
+Our Public API surface is tracked using golden files.
 
-You can also test all packages by running:
+You check all golden files by running:
 ```bash
-yarn bazel test //etc/api ...
+pnpm public-api:check
 ```
 
 If you modified the public API, the test will fail. To update the golden files you need to run:
-
 ```bash
-yarn bazel run //etc/api:angular_devkit_core_api.accept
-```
-
-**Note**: In some cases we use aliased symbols to create namespaces.
-
-Example:
-```javascript
-import * as foo from './foo';
-
-export { foo };
+pnpm public-api:update
 ```
-There are currently not supported by the API guardian.
-To overcome this limitation we created `_golden-api.ts` in certain packages.
-
-When adding a new API, it might be the case that you need to add it to `_golden-api.ts`.

-## The Goal of Angular CLI
+<hr>
 
-The Angular CLI creates, manages, builds and test your Angular projects. It's built on top of the
-Angular DevKit.
+## Documentation
 
-## The Goal of DevKit
+Get started with Angular CLI, learn the fundamentals and explore advanced topics on our documentation website.
 
-DevKit's goal is to provide a large set of libraries that can be used to manage, develop, deploy and
-analyze your code.
+- [Getting started][quickstart]
+- [CLI][cli]
+- [Workspace and project file structure][filestructure]
+- [Workspace configuration][workspaceconfig]
+- [Schematics][schematics]
 
-# Getting Started - Local Development
+## Development Setup
 
-## Installation
 
-To get started locally, follow these instructions:
+### Prerequisites
 
-1. If you haven't done it already, [make a fork of this repo](https://github.com/angular/angular-cli/fork).
-1. Clone to your local computer using `git`.
-1. Make sure that you have Node 10.13 or later installed. See instructions [here](https://nodejs.org/en/download/).
-1. Make sure that you have `yarn` installed; see instructions [here](https://yarnpkg.com/lang/en/docs/install/).
-1. Run `yarn` (no arguments) from the root of your clone of this project to install dependencies.
+- Install [Node.js] which includes [Node Package Manager][npm]
 
-## Building and Installing the CLI
+### Setting Up a Project
 
-To make a local build:
+Install the Angular CLI globally:
 
-```shell
-yarn build --local
+```
+npm install -g @angular/cli
 ```
 
-This generates a number of tarballs in the `dist/` directory. To actually use
-the locally built tools, switch to another repository reproducing the specific
-issue you want to fix (or just generate a local repo with `ng new`). Then
-install the locally built packages:
+Create workspace:
 
-```shell
-cd "${EXAMPLE_ANGULAR_PROJECT_REPO}"
-npm install -D ${CLI_REPO}/dist/*.tgz
+```
+ng new [PROJECT NAME]
 ```
 
-Builds of this example project will use tooling created from the previous local
-build and include any local changes. When using the CLI, it will automatically
-check for a local install and use that if present. This means you can just run:
+Run the application:
 
-```shell
-npm install -g @angular/cli
+```
+cd [PROJECT NAME]
+ng serve
 ```
 
-to get a global install of the latest CLI release. Then running any `ng` command
-in the example project will automatically find and use the local build of the
-CLI.
+Angular is cross-platform, fast, scalable, has incredible tooling, and is loved by millions.
 
-Note: If you are testing `ng update`, be aware that installing all the tarballs
-will also update the framework (`@angular/core`) to the latest version. In this
-case, simply install the CLI alone with
-`npm install -D ${CLI_REPO}/dist/_angular_cli.tgz`, that way the rest of the
-project remains to be upgraded with `ng update`.
+## Quickstart
 
-## Debugging
+[Get started in 5 minutes][quickstart].
 
-To debug an invocation of the CLI, [build and install the CLI for an example
-project](#building-and-installing-the-cli), then run the desired `ng` command
-as:
+## Ecosystem
 
-```shell
-node --inspect-brk node_modules/.bin/ng ...
-```
+<p>
+  <img src="http://github.com/docs/images/angular-ecosystem-logos.png" alt="angular ecosystem logos" width="500px" height="auto">
+</p>
 
-This will trigger a breakpoint as the CLI starts up. You can connect to this
-using the supported mechanisms for your IDE, but the simplest option is to open
-Chrome to [chrome://inspect](chrome://inspect) and then click on the `inspect`
-link for the `node_modules/.bin/ng` Node target.
+- [Angular Framework][adev]
+- [Angular Material][angularmaterial]
 
-Unfortunately, the CLI dynamically `require()`'s other files mid-execution, so
-the debugger is not aware of all the source code files before hand. As a result,
-it is tough to put breakpoints on files before the CLI loads them. The easiest
-workaround is to use the `debugger;` statement to stop execution in the file you
-are interested in, and then you should be able to step around and set breakpoints
-as expected.
+## Changelog
 
-## Testing
+[Learn about the latest improvements][changelog].
 
-There are three different test suites which can be run locally:
+## Upgrading
 
-* Unit tests
-  * Run: `yarn test --full`
-  * Debug: `yarn debug:test --full`
-* Large tests
-  * Run: `yarn test-large --full`
-  * Debug: `yarn debug:test-large --full`
-* End to end tests
-  * Run: `node tests/legacy-cli/run_e2e.js`
-  * Run subset of tests: `node tests/legacy-cli/run_e2e.js tests/legacy-cli/e2e/tests/i18n/ivy-localize-*`
+Check out our [upgrade guide](https://update.angular.dev/) to find out the best way to upgrade your project.
 
-When running the debug commands, Node will stop and wait for a debugger to
-attach. You can attach your IDE to the debugger to stop on breakpoints and step through the code. Also see [IDE Specific Usage](#ide-specific-usage) for a
-simpler debug story.
+## Contributing
 
-When debugging a specific test, change `describe()` or `it()` to `fdescribe()`
-and `fit()` to focus execution to just that one test. This will keep the output clean and speed up execution by not running irrelevant tests.
+### Contributing Guidelines
 
-## IDE Specific Usage
+Read through our [contributing guidelines][contributing] to learn about our submission process, coding rules and more.
 
-Some additional tips for developing in specific IDEs.
+### Want to Help?
 
-### Intellij IDEA / WebStorm
+Want to report a bug, contribute some code, or improve documentation? Excellent! Read up on our guidelines for [contributing][contributing] and then check out one of our issues labeled as <kbd>[help wanted](https://github.com/angular/angular-cli/labels/help%20wanted)</kbd> or <kbd>[good first issue](https://github.com/angular/angular-cli/labels/good%20first%20issue)</kbd>.
 
-To load the project in Intellij products, simply `Open` the repository folder.
-Do **not** `Import Project`, because that will overwrite the existing
-configuration.
+### Code of Conduct
 
-Once opened, the editor should automatically detect run configurations in the
-workspace. Use the drop down to choose which one to run and then click the `Run`
-button to start it. When executing a debug target, make sure to click the
-`Debug` icon to automatically attach the debugger (if you click `Run`, Node will
-wait forever for a debugger to attach).
+Help us keep Angular open and inclusive. Please read and follow our [Code of Conduct][codeofconduct].
 
-![Intellij IDEA run configurations](docs/images/run-configurations.png)
+### Developer Guide
 
-## Creating New Packages
+Read through our [developer guide][developer] to learn about how to build and test the Angular CLI locally.
 
-Adding a package to this repository means running two separate commands:
 
-1. `schematics devkit:package PACKAGE_NAME`. This will update the `.monorepo` file, and create the
-  base files for the new package (package.json, src/index, etc).
-1. `devkit-admin templates`. This will update the README and all other template files that might
-  have changed when adding a new package.
+## Community
 
-For private packages, you will need to add a `"private": true` key to your package.json manually.
-This will require re-running the template admin script.
+Join the conversation and help the community.

- * This file includes polyfills needed by Angular and is loaded before the app.

- *
- * This file is divided into 2 sections:
- *   1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
- *   2. Application imports. Files imported after ZoneJS that should be loaded before your main
- *      file.
- *
- * The current setup is for so-called "evergreen" browsers; the last versions of browsers that
- * automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
- * Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.

-# OneOhProject
-
-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 1.0.0.
-
-## Development server
-
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-## Code scaffolding
-
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive/pipe/service/class/module`.
-
-## Build
-
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `-prod` flag for a production build.
-
-## Running unit tests
-
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
-
-## Running end-to-end tests
-
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
-Before running the tests make sure you are serving the app via `ng serve`.
-
-## Further help
-
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).

+# SeventeenProject
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 17.3.12.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The application will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.

+# 17SsrProjectWebpack
+
+This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 16.2.10.
+
+## Development server
+
+Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The application will automatically reload if you change any of the source files.
+
+## Code scaffolding
+
+Run `ng generate component component-name` to generate a new component. You can also use `ng generate --help` to see all the available schematics you can generate.
+
+## Build
+
+Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
+
+## Running unit tests
+
+Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+
+## Running end-to-end tests
+
+Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
+
+## Further help
+
+To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview](https://angular.dev/tools/cli) and [Command Reference](https://angular.dev/cli) pages.

-# build_event_protocol
-
-This protocol is used to make streaming build results available for machines to
-read and process.
-
-See https://docs.bazel.build/versions/master/build-event-protocol.html
-
-This directory contains an example program that parses a streaming JSON file
-containing build events. It's useful for manually testing a program that emits
-the build event protocol.
-
-## Try it
-
-First build the tool:
-
-```sh
-$ bazel build //tools/build_event_protocol:parse
-```
-
-Then produce a build event json file:
-
-$ bazel test //... --build_event_json_file=bep.json
-
-as soon as that process has started, you should be able to run in another window
-
-$ bazel-bin/tools/build_event_protocol/parse bep.json
