    Bootstrap Icons

    Bootstrap Icons

    Open source SVG icon library for Bootstrap

    Free, high-quality, open-source icon library with over 1,600 icons. Include them any way you like, SVGs, SVG sprite, or web fonts. Use them with or without Bootstrap in any project. Bootstrap Icons are published to npm, but they can also be manually downloaded if needed. Bootstrap Icons are SVGs, so you can include them into your HTML in a few ways depending on how your project is setup. We recommend using a width: 1em (and optionally height: 1em) for easy resizing via font-size. Embed your icons within the HTML of your page (as opposed to an external image file). Here we’ve used a custom width and height. Use the SVG sprite to insert any icon through the <use> element. Use the icon’s filename as the fragment identifier (e.g., toggles is #toggles). SVG sprites allow you to reference an external file similar to an <img> element, but with the power of currentColor for easy theming.

    jQuery

    jQuery

    jQuery JavaScript library

    jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery also supports Node, browser extensions, and other non-browser environments. To build jQuery, you need to have the latest Node.js/npm and git 1.7 or later. Earlier versions might work, but are not supported. Special builds can be created that exclude subsets of jQuery functionality. This allows for smaller custom builds when the builder is certain that those parts of jQuery are not being used. For example, an app that only used JSONP for $.ajax() and did not need to calculate offsets or positions of elements could exclude the offset and ajax/xhr modules.

    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

    Retire.js

    Retire.js

    Scanner detecting the use of JavaScript libraries

    There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP.

    SQLite compiled to JavaScript

    SQLite compiled to JavaScript

    A javascript library to run SQLite on the web

    sql.js is a javascript SQL database. It allows you to create a relational database and query it entirely in the browser. You can try it in this online demo. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a JavaScript typed array. sql.js uses emscripten to compile SQLite to webassembly (or to javascript code for compatibility with older browsers). It includes contributed math and string extension functions. sql.js can be used like any traditional JavaScript library. If you are building a native application in JavaScript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to JavaScript. A native binding will not only be faster because it will run native code, but it will also be able to work on database files directly instead of having to load the entire database.

    TensorFlow

    TensorFlow

    TensorFlow is an open source library for machine learning

    Originally developed by Google for internal use, TensorFlow is an open source platform for machine learning. Available across all common operating systems (desktop, server and mobile), TensorFlow provides stable APIs for Python and C as well as APIs that are not guaranteed to be backwards compatible or are 3rd party for a variety of other languages. The platform can be easily deployed on multiple CPUs, GPUs and Google's proprietary chip, the tensor processing unit (TPU). TensorFlow expresses its computations as dataflow graphs, with each node in the graph representing an operation. Nodes take tensors—multidimensional arrays—as input and produce tensors as output. The framework allows for these algorithms to be run in C++ for better performance, while the multiple levels of APIs let the user determine how high or low they wish the level of abstraction to be in the models produced. Tensorflow can also be used for research and production with TensorFlow Extended.
