React Redux
React bindings for Redux
React Redux is the official React binding for Redux. It lets your React components read data from a Redux store, and dispatch actions to the store to update data. React Redux is maintained by the Redux team, and kept up-to-date with the latest APIs from Redux and React. Designed to work with React's component model. You define how to extract the values your component needs from Redux, and your component receives them as props. Creates wrapper components that manage the store interaction logic for you, so you don't have to write it yourself. Automatically implements complex performance optimizations, so that your own component only re-renders when the data it needs has actually changed. Redux itself is a standalone library that can be used with any UI layer or framework, including React, Angular, Vue, Ember, and vanilla JS. Although Redux and React are commonly used together, they are independent of each other. -

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. -

Relative-Time Element
Web component extensions to the standard <time> element
Formats a timestamp as a localized string or as relative text that auto-updates in the user's browser. This allows the server to cache HTML fragments containing dates and lets the browser choose how to localize the displayed time according to the user's preferences. Every visitor is served the same markup from the server's cache. When it reaches the browser, the custom relative-time JavaScript localizes the element's text into the local timezone and formatting. Dates are displayed before months, and a 24-hour clock is used, according to the user's browser settings. If the browser's JavaScript is disabled, the default text served in the cached markup is still displayed. -

Relay
JavaScript framework for building data-driven React applications
Relay is data-fetching turned declarative. Components declare their data dependencies, without worrying about how to fetch them. Relay guarantees that the data each component needs is fetched and available. This keeps components decoupled and promotes reuse. With Relay, components and their data dependencies can be quickly modified without modifying other parts of the system. That means you won't accidentally break other components as you refactor or make changes to your app. Relay's compiler aggregates and optimizes the data requirements for your entire app, so that they can be efficiently fetched in a single GraphQL request. Relay handles the heavy lifting to ensure the data declared by your components is fetched in the most efficient way. For example, by deduplicating identical fields, and precomputing information used at runtime, among other optimizations. Relay also supports executing GraphQL Mutations, optionally with optimistic updates, and updates to local data. -

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. -
