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. -

React Transform Boilerplate
A new Webpack boilerplate with hot reloading React components
React Transform Boilerplate is an archived Webpack starter project that demonstrated component-level hot reloading and development-time error handling for React. It used Babel transforms to inject development behavior into React components. Updated components could be replaced while the application remained running, reducing the need for complete browser reloads. Runtime and rendering errors could be surfaced closer to the affected module or component. Separate development and production Webpack configurations illustrated how debugging transforms could remain isolated from production builds. The project served as an experimental successor to earlier hot-loading approaches during a transitional period in React tooling. It was archived in 2020 and now recommends React Refresh Webpack Plugin for modern applications. -

React-WeUI
WeUI Components build with React
React-WeUI is a React component library that brings WeUI, the interface system associated with WeChat-style mobile design, into the React development workflow. Its purpose is to let developers build mobile-oriented interfaces with React while preserving the visual language and component behavior expected from WeUI. The project combines React components with the underlying WeUI styling, which means teams can work in a modern component architecture instead of manually stitching together markup and CSS for each screen. The repository includes documentation with live examples, installation options for both package managers and browser-based usage, and example code that shows how quickly a page can be assembled from imported components. Because of its heritage, React-WeUI is especially relevant for mobile web experiences, lightweight app-like pages, and products targeting users familiar with WeChat-inspired interaction patterns. -

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. -

Reflexbox
Responsive React Flexbox Grid System
Reflexbox is a React utility library that provides a set of flexible layout components built on top of the CSS Flexbox specification, enabling developers to create responsive layouts with minimal effort. It introduces components such as Box and Flex that abstract common layout patterns into reusable primitives, allowing developers to apply spacing, alignment, and sizing through props rather than writing custom CSS. The library integrates seamlessly with styled-system, enabling theme-based design and consistent spacing scales across applications. Reflexbox is designed to be highly composable, allowing developers to build complex layouts by combining simple components. It emphasizes responsiveness by supporting array-based props that adapt styles across breakpoints. The library is lightweight and focuses on performance, making it suitable for both small projects and large-scale applications. -

Reselect
Selector library for Redux
Simple “selector” library for Redux (and others) inspired by getters in NuclearJS, subscriptions in re-frame and this proposal from speedskater. Selectors can compute derived data, allowing Redux to store the minimal possible state. Selectors are efficient. A selector is not recomputed unless one of its arguments changes. Selectors are composable. They can be used as input to other selectors. Reselect provides a function createSelector for creating memoized selectors. createSelector takes an array of input-selectors and a transform function as its arguments. If the Redux state tree is mutated in a way that causes the value of an input-selector to change, the selector will call its transform function with the values of the input-selectors as arguments and return the result. If the values of the input-selectors are the same as the previous call to the selector, it will return the previously computed value instead of calling the transform function. -

Resumable.js
Library for providing multiple uploads via the HTML5 File API
Resumable.js is a JavaScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API. The library is designed to introduce fault-tolerance into the upload of large files through HTTP. This is done by splitting each file into small chunks. Then, whenever the upload of a chunk fails, uploading is retried until the procedure completes. This allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows for users to pause, resume and even recover uploads without losing state because only the currently uploading chunks will be aborted, not the entire upload. Resumable.js does not have any external dependencies other than the HTML5 File API. This is relied on for the ability to chunk files into smaller pieces. Currently, this means that support is widely available in to Firefox 4+, Chrome 11+, Safari 6+ and Internet Explorer 10+. -

Riot
Simple and elegant component-based UI library
Why do we need a new UI library? The frontend space is indeed crowded, but we honestly feel the solution is still “out there”. We believe Riot.js offers the right balance for solving the great puzzle. Riot.js brings custom elements to all modern browsers without the use of any polyfill! A custom element glues relevant HTML and JavaScript together forming a reusable component. It is designed to offer you everything you wished native the web components API looked like. HTML syntax is the de facto language of the web and it’s designed for building user interfaces. The syntax is explicit, nesting is inherent to the language, and attributes offer a clean way to provide options for custom tags. Minimalism sets Riot.js apart from others. One of the design goals was to introduce a powerful tag syntax with as little boilerplate as possible. Riot.js has between 10 and 100 times fewer API methods than other UI libraries. -

Rules And Scripts
Shunt rules, rewrite rules, and scripts
Rules And Scripts is a large rules-and-scripts repository for traffic routing rules, rewrite rules, and automation scripts. It organizes community-sourced rule material and script resources into a single reference collection. The project is mainly written for learning and research around ES6 and rule-based automation. It includes routing rules, rewrite resources, external collections, icons, blank templates, and automation scripts. Some scripts are prepared for Quantumult X Gallery and BoxJS-style subscription workflows. Because the repository depends on third-party tools, external rule data, and user-filled configurations, users need to evaluate legality, accuracy, and suitability for their own environment. -
