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
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
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
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 Developer Roadmap
Roadmap to becoming a React developer
React Developer Roadmap is an open-source educational guide that outlines the knowledge and technologies needed to become a React developer. Originally created as a 2019 learning roadmap, it presents a visual progression from fundamental web development to advanced frontend practices. Beginners can explore HTML, CSS, JavaScript, Git, HTTP, and command-line skills. The guide then introduces React components, state management, routing, and application architecture. Additional recommendations cover testing, styling solutions, static typing, and development tools. Curated educational resources help learners investigate individual topics and choose suitable technologies. The roadmap is available in several languages, including English, Spanish, Chinese, Japanese, Korean, Portuguese, and Russian. It is a historical learning reference rather than a continuously updated course. -

React Native Extended StyleSheet
Extended StyleSheets for React Native
React Native Extended StyleSheet is a drop-in styling extension for React Native that adds capabilities beyond the standard StyleSheet API. It lets developers define global and local variables for reusable styling values. Media queries and relative units make layouts more adaptable to different screen sizes. The library supports dynamic themes that can recalculate application styles when theme variables change. It also provides percentages, mathematical expressions, scaling, pseudo-classes, caching, and function-based values. The project is deprecated and no longer receives updates or support. -

React Native Vector Icons
Customizable Icons for React Native with full styling
Perfect for buttons, logos and nav/tab bars. Easy to extend, style and integrate into your project. If you want to use any of the bundled icons, you need to add the icon fonts to your Xcode project. For each platform (iOS/Android/Windows) you plan to use, follow one of the options for the corresponding platform. Upgrading this package often requires the font files linked to your projects to be updated as well. If the automatic linking works for you, running this again should update the fonts. You can either use one of the bundled icons supported or roll your own custom font. Since Icon builds on top of the Text component, most style properties will work as expected, you might find it useful to play around with background color, border width, border color, border radius, padding, margin, color, font size, etc. -

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 Slick
React carousel component
This library is the port of jQuery slick library. React slick is a carousel component built with React. It is a react port of slick carousel. The easiest way to try out react-slick is using the Code Sandbox example. After you are done installing through yarn or npm, now you will have to include CSS in your project. But be aware slick-carousel has a peer-dependancy on jQuery which you, or your colleagues may not like to see in your console output, so you can always grab the CSS from there and convert it into any CSS in JS solution that you might be using. -

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.
