Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

18.2.20 (18.2.x latest)

Description

When using @angular-devkit/[email protected], running yarn shows this warning:

$ yarn
yarn install v1.22.22
...
warning "@angular-devkit/[email protected] > @vitejs/[email protected]"
        has unmet peer dependency "vite@^6.0.0".

This happens because @angular-devkit/build-angular includes @vitejs/plugin-basic-ssl, which has a peer dependency on vite.
However, build-angular itself does not actually use this plugin, so the dependency is unnecessary.

This issue was fixed once in v18.2.x (issue: #29921 , PR: #29928 ),
but the problem exists in v19 and v20, as well as in older v18.x versions before the fix.

To fix this, the dependency on @vitejs/plugin-basic-ssl should be removed from @angular-devkit/build-angular, just like in v18.2.x.

Minimal Reproduction

In package.json:

{
...
  "devDependencies": {
    "@angular/cli": "20.0.1",
    "@angular-devkit/build-angular": "20.0.0"
  }
...
}

Then run:

yarn

You will get:

warning "@angular-devkit/[email protected] > @vitejs/[email protected]" has unmet peer dependency "vite@^6.0.0".
