    A-Frame

    A-Frame

    A web framework for building virtual reality experiences

    A-Frame is an open source web framework for building virtual reality experiences. With A-Frame you can create WebVR with HTML and entity-component works on Vive, Rift, Daydream and more. A-Frame simplifies virtual reality by handling the required 3D and WebVR boilerplate to get you running on platforms like mobile, desktop, Vive, and Rift. Because it can be used from HTML, just about everyone can use it. A-Frame is a thin yet powerful framework on top of three.js. While A-Frame is completely accessible from HTML, developers can also make full use of JavaScript, DOM APIs, three.js, WebVR, and WebGL.

    Advanced REST Client application

    Advanced REST Client application

    Advanced REST Client - Desktop application

    This is the main repository for the ARC Electron application. If you are still using Chrome plug-in then proceed to move From Chrome To the Desktop Client section. The original Chrome application is discontinued as Chrome stopped supporting browser-based applications. ARC was built as an open-source and free for everyone API tool out of a passion for giving the developer community tools they need. The application and related projects (like API Console) are created and distributed to our users for free. Our vision is that API tools are available for every developer and organization, regardless of their size, for free and without forced relationship. API tools are using open standards to communicate with other applications so developers can build integrations. Originally the application was created by the author for own convenience while developing APIs. It quickly turned out to be a common problem among developers to consume APIs during the development process.

    Concise CLI

    Concise CLI

    A CSS framework that's lightweight and easy-to-use

    The Concise CLI can be used independently of any styles. In principle, it would will with any other CSS library, framework or any existing project so long as the code is plain CSS or contains only the features that can be compiled with PostCSS. Of course, one can start writing everything from scratch using Concise as well. The core library contains the very basic styles that one might use, and contains most of the code that was available on Concise v4. No unnecessary styles are added so you can spend more time building and less time overriding. Do you need CSS components? We provide a basic UI kit for Concise CSS as an add-on. We also provide utility classes for rapid prototyping and context-dependent styles. The usual features from Sass with some custom additions using PostCSS. A framework built with design in mind. Get better results from the beginning with less code.

    FastClick

    FastClick

    Easy-to-use library to remove click delays on browsers with touch UIs

    FastClick is a simple, easy-to-use library for eliminating the 300ms delay between a physical tap and the firing of a click event on mobile browsers. The aim is to make your application feel less laggy and more responsive while avoiding any interference with your current logic. FastClick is developed by FT Labs, part of the Financial Times. Note: As of late 2015 most mobile browsers - notably Chrome and Safari - no longer have a 300ms touch delay, so fastclick offers no benefit on newer browsers, and risks introducing bugs into your application. Consider carefully whether you really need to use it. The library has been deployed as part of the FT Web App. FastClick doesn't attach any listeners on desktop browsers.

    Google Closure Compiler

    Google Closure Compiler

    A JavaScript checker and optimizer

    Closure Compiler is a production-grade JavaScript optimizer and checker that parses JS, analyzes it, removes dead code, rewrites and minifies what remains, and emits faster, smaller bundles. Beyond minification, it performs advanced optimizations such as inlining, property collapsing, type-guided rewrites, and cross-module motion, often yielding substantial load-time wins. It includes a strong static checker that validates syntax, variable references, and type annotations (Closure types or JSDoc), catching bugs early and enabling aggressive transformations safely. The ecosystem provides a Java implementation, npm/JS builds, and documentation for integrating in modern toolchains. Closure Compiler has been used extensively at scale within Google and by the broader community, proving its robustness on very large codebases. Companion repositories track npm packaging and a JS-only variant for environments where running Java is undesirable.

    Jupyter Notebooks extensions

    Jupyter Notebooks extensions

    A collection of various notebook extensions for Jupyter

    The jupyter_contrib_nbextensions package contains a collection of community-contributed unofficial extensions that add functionality to the Jupyter notebook. These extensions are mostly written in Javascript and will be loaded locally in your browser. For Jupyter version 4 or 5, use the master branch of the repository. Most nbextensions have been updated to work with both Jupyter 4.x and 5.x, but occasionally things get missed, or the Jupyter API changes in a minor version update, so if anything doesn't work as you'd expect/hope, please do check the issues, or open a new one as necessary! The Python package installation step is necessary to allow painless installation of the nbextensions together with additional items like nbconvert templates, pre-/postprocessors, and exporters. All of the nbextensions in this repo are provided as parts of a python package, which is installable in the usual manner.

    Meny

    Meny

    A three dimensional and space effecient menu

    Meny is an off-canvas, edge-triggered menu concept that slides into view when the user moves the mouse to the edge of the screen or performs a similar gesture. It was created to explore more playful and discoverable navigation than the usual hamburger menu, especially on large screens. The menu itself lives off-screen and is revealed with a smooth CSS transform, leaving most of the page untouched. Because it’s just HTML, CSS, and a bit of JavaScript, it’s easy to restyle for sidebars, tool palettes, or documentation navigation. Meny works particularly well on interactive sites, demos, or dashboards where you want quick access to options without permanent UI clutter. It’s a good example of “progressive” navigation: always there, but not always visible.

    Mocha

    Mocha

    A feature-rich JavaScript test framework running on Node.js

    Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks.

    React Projects

    React Projects

    Collection of React example / tutorial projects

    This repository is a collection of small-to-medium React applications that showcase practical patterns, from stateful widgets to multi-page interfaces. Each project is self-contained and demonstrates specific techniques—hooks for state and effects, context for global state, custom hooks for reuse, and reducer patterns for complex updates. The codebases include common UI tasks like forms, modals, lists, filtered search, and pagination, along with data fetching and basic routing where appropriate. Because every project focuses on a narrow set of concepts, learners can clone a single folder, run it, and grasp the idea without wading through a monolith. The examples are structured to be approachable yet idiomatic, encouraging good habits while staying close to what developers actually build. Over time, the collection functions as a portfolio of reference implementations that students and practitioners can adapt to new projects.
