    QuoJS

    QuoJS

    Micro #JavaScript Library for Mobile Devices

    QuoJS is a lightweight JavaScript library aimed at building mobile-first web interfaces with a focus on touch interactions and simple DOM utilities. It provides a compact, jQuery-like API for element selection, traversal, and manipulation, but trims the surface area to keep payloads small for mobile browsers. A core feature set centers on high-level touch gestures—such as tap, double-tap, swipe, pinch, and long-tap—abstracting away platform quirks so developers can attach handlers consistently across devices. The library embraces modern browser features and CSS3 where available, offering helpers that make common mobile UI patterns feel responsive and fluid. Because it is intentionally minimal, QuoJS plays well as a drop-in alongside other client libraries when you only need fast gestures and a few utilities rather than a full framework. Its API is designed to be readable and chainable.

    Raphaël

    Raphaël

    JavaScript vector library

    Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library. Raphaël ['ræfeɪəl] uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy. Raphaël currently supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+. Versions will be released as we gather and test new PRs. As there are a lot of browsers being supported it might take a while to accept a PR, we will use the feedback from other users too. You can use the raphaelTest.html to try things, you need to start a server in the root dir to start testing things there.

    RateIt

    RateIt

    Rating plugin for jQuery. Fast, Progressive enhancement, touch support

    Rating plugin for jQuery. Fast, Progressive enhancement, touch support, customizable (just swap out the images, or change some CSS), Unobtrusive JavaScript (using HTML5 data-* attributes), RTL support, supports as many stars as you'd like, and also any step size. Although it does the same job as the rest of the jQuery star rating plugins, the main difference is its simplicity. Most plugins create an element for each (partial) star, be it a div with a star background, or an img tag. Each of these tags gets a hover event, and a click event. And on these hover/click events it has to go and talk to the other stars, telling them to change their state.

    React Beautiful DnD

    React Beautiful DnD

    Beautiful and accessible drag and drop for lists with React

    React Beautiful DnD is a drag-and-drop library for React that emphasizes fluid motion, accessibility, and natural constraints. It provides Draggable and Droppable primitives that manage state, sensors, and reordering logic for you, so you focus on rendering. Keyboard support, screen-reader announcements, and predictable focus handling make interactions accessible beyond the mouse. The library computes dimensions and movement carefully to avoid jank, including automatic scrolling and collision handling when lists overflow. It supports common patterns like reordering within a list, moving items between multiple lists, and integrating with virtualized lists. Clear lifecycle callbacks expose what changed during a drag so you can persist updates or trigger side effects reliably.

    React Demos

    React Demos

    A collection of simple demos of React.js

    This repository is a curated collection of small, focused React examples intended to illustrate core concepts through runnable code. Each demo isolates a single idea—such as component composition, state and props, lifecycle hooks, or event handling—so learners can see cause and effect without framework noise. The code favors clarity over abstraction, making it easy to copy, tweak, and compare different approaches to the same problem. Many examples are deliberately minimal, showing just enough HTML, CSS, and JavaScript to highlight the React pattern being taught. The structure encourages hands-on learning: open a demo, modify a prop or state update, and observe how the UI reacts. It works well as a study companion for beginners or as a quick refresher before building larger applications.

    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.

    React Toolbox

    React Toolbox

    A set of React components implementing Google's Material Design

    React Toolbox is a set of React components that implements Google Material Design specification. It's built on top of some the trendiest proposals like CSS Modules (written in SASS), Webpack and ES6. The library harmoniously integrates with your Webpack workflow and it's easily customizable and very flexible. Check our awesome documentation (which is built using React Toolbox) and try all the components with live examples. We've created a playground so you don't need to install anything to fall in love with our components, so fun! React Toolbox uses CSS Modules by default to import stylesheets written using PostCSS & postcss-preset-env features. In case you want to import the components already bundled with CSS, your module bundler should be able to require these PostCSS modules. Of course this is a set of React components so you should be familiar with React. If want to customize your components via themes, you may want to take a look to react-css-themr, used by React Toolbox.

    Recompose

    Recompose

    React utility belt for function components and higher-order components

    Recompose is a React utility belt for function components and higher-order components. Think of it like lodash for React. You can use Recompose to lift state into functional wrappers, perform the most common React patterns, optimize rendering performance, interoperate with other libraries, build your own libraries, etc. Recompose helpers integrate really nicely with external libraries like Relay, Redux, and RxJS. Recompose focuses on higher-order components. HoCs are functions that accept a base component and return a new component with additional functionality. They can be used to abstract common tasks into reusable pieces. Recompose provides a toolkit of helper functions for creating higher-order components. Many React libraries end up implementing the same utilities over and over again, like shallowEqual and getDisplayName. Recompose provides these utilities for you. Although Recompose encourages the use of function components whenever possible it works with normal React components.
