This is a list of AWESOME components. Nope, it's NOT a comprehensive list of every React component under the sun. So, what does "awesome" mean? Well:

• It solves a real problem
• It does so in a 🦄 unique, 🦋 beautiful, or 🏆 exceptional way. (And it's not super popular and well-known... no point in listing those.)
• It has recent code commits!

Look for a 🚀 for truly amazing projects. And look for quickie maintainer commentary and reviews in (italic parens) after some listings of note.

Custom React hooks allow developers to abstract the business logic of components into single, reusable functions.
I have noticed that many of the hooks I have created and shared across projects involve callbacks, references, events, and dealing with the component lifecycle.
Therefore, I have created beautiful-react-hooks, a collection of useful React hooks that may help other developers speed up their development process.
Moreover, I have strived to create a concise and practical API that emphasizes code readability, while keeping the learning curve as low as possible, making it suitable for larger teams to use and share t -- Please before using…

A simple, scalable, and powerful architecture for building production ready React applications.

React is an excellent tool for building front-end applications. It has a diverse ecosystem with hundreds of great libraries for literally anything you might need. However, being forced to make so many choices can be overwhelming. It is also very flexible, you can write React applications in any way you like, but that flexibility comes with a cost. Since there is no pre-defined architecture that developers can follow, it often leads to a messy, inconsistent, and over-complicated codebase.

This repo attempts to present a way of creating React applications using some of the best tools in the ecosystem with a good project structure that scales very well. Based on my experience working with a lot of different codebases, this architecture turns out to be the most effective.

The goal here is to serve…

React is a JavaScript library for building user interfaces.

• Declarative: React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
• Component-Based: Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
• Learn Once, Write Anywhere: We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using React Native.

Roadmap to becoming a React developer in 2019:

Below you can find a chart demonstrating the paths that you can take and the libraries that you would want to learn to become a React developer. I made this chart as a tip for everyone who asks me, "What should I learn next as a React developer?"

The purpose of this roadmap is to give you an idea about the landscape. The road map will guide you if you are confused about what to learn next, rather than encouraging you to pick what is hip and trendy. You should grow some understanding of why one tool would be better suited for some cases than the other and remember hip and trendy does not always mean best suited for…

A Cheatsheet with live editable examples 💪

• A one-stop reference for the React hooks APIs
• Doesn't replace the official docs.
• However, it contains actual code examples each mimicking all APIs of hooks.
• Contains some real world examples of cases / issues you'll likely run into
• Most importantly, the cheatsheet contains live editable codes.

• includes live examples 🙋‍

👉🏿👉🏿👉🏿 Get Started

• Add example call signatures to all hooks
• Add more examples that explain interesting use cases from the official Hooks FAQ

Contributions of any kind are welcome. If you wanna knock off any of the todos above, please feel free to issue a PR. Got an interesting idea for the cheatsheet? Issue a PR :)

Official React bindings for Redux Performant and flexible.

The recommended way to start new apps with React and Redux is by using our official Redux+TS template for Vite, or by creating a new Next.js project using Next's with-redux template.

Both of these already have Redux Toolkit and React-Redux configured appropriately for that build tool, and come with a small example app that demonstrates how to use several of Redux Toolkit's features.

# Vite with our Redux+TS template
# (using the `degit` tool to clone and extract the template)
npx degit reduxjs/redux-templates/packages/vite-template-redux my-app

# Next.js using the `with-redux` template
npx create-next-app --example with-redux my-app

React Redux 8.0 requires React 16.8.3 or later (or React Native 0.59 or later).

To use React Redux with your React app, install it as a dependency:

# If you use npm:

React Router is a lightweight, fully-featured routing library for the React JavaScript library. React Router runs everywhere that React runs; on the web, on the server (using node.js), and on React Native.

If you're new to React Router, we recommend you start with the tutorial.

If you're migrating to v6 from v5 (or v4, which is the same as v5), check out the migration guide. If you're migrating from Reach Router, check out the migration guide for Reach Router. If you need to find the code for v5, it is on the v5 branch.

Documentation for v6 can be found on our website.

There are many different ways to contribute to React Router's development. If you're interested, check out our contributing guidelines to learn how you can get involved.

This repository is a monorepo containing the following packages:

react-spring is a cross-platform spring-physics first animation library.

It's as simple as:

const styles = useSpring({
  from: {
    opacity: 0
  },
  to: {
    opacity: 1
  }
})

<animated.div style={styles} />

Just a small bit about us:

• Cross-Platform: We support react-dom, react-native, react-three-fiber, react-konva & react-zdog.
• Versatile: Be declarative with your animations or if you prefer, imperative.
• Spring-Physics First: By default animation use springs for fluid interactivity, but we support durations with easings as well.

There's a lot more to be had! Give it a try and find out.

You want to write maintainable tests for your React components. As a part of this goal, you want your tests to avoid including implementation details of your components and rather focus on making your tests give you the confidence for which they are intended. As part of this, you want your testbase to be maintainable in the long run so refactors of your components (changes to implementation but not functionality) don't break your tests and slow you and your team down.

Decouple your Authentication and Authorization from your components!

npm install --save redux-auth-wrapper

redux-auth-wrapper is a utility library for handling authentication and authorization in react + redux applications.

Read the documentation at https://mjrussell.github.io/redux-auth-wrapper

Version 3.x has the same external API as version 2, however it only supports React >= 16.3. It is also tested with react-router v5 and connected-react-router which replaced react-router-redux.

Version 2.x is a big internal rewrite! It provides a massive increase in flexibility when using redux-auth-wrapper and also introduces some breaking changes. See the Migration Guide for more details if coming from 1.x. Or check out the Getting Started guide if you've never used redux-auth-wrapper before.

Looking for Version 1.x? You can browse the 1.x README here.

This repository contains an explanation of inner work of React. In fact, I was debugging through the entire code base and put all the logic on visual block-schemes, analyzed them, summarized and explained main concepts and approaches. I've already finished with Stack version and now I work with the next, Fiber version.

Each scheme is clickable and can be opened in a new tab, use that to zoom it and be able to read from it. Keep the article and a scheme you are reading about at that moment in separate windows (tabs), that will help to match text and code flow easier.
