# Redux is a predictable state container for JavaScript apps. (Not to be confused with a WordPress framework – [Redux Framework](https://redux.io)) It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test. On top of that, it provides a great developer experience, such as [live code editing combined with a time traveling debugger](https://github.com/reduxjs/redux-devtools). You can use Redux together with [React](https://reactjs.org), or with any other view library. It is tiny (2kB, including dependencies), and has a rich ecosystem of addons.

It wraps around the Redux core, and contains packages and functions that we think are essential for building a Redux app. Redux Toolkit builds in our suggested best practices, simplifies most Redux tasks, prevents common mistakes, and makes it easier to write Redux applications. ``` npm install @reduxjs/toolkit react-redux ``` For the Redux core library by itself: ``` npm install redux ``` For more details, see [the Installation docs page](https://redux.js.org/introduction/installation). ## Documentation The Redux docs are located at **https://redux.js.org**: - [Introduction](https://redux.js.org/introduction/getting-started) - [Tutorials](https://redux.js.org/tutorials/index) - [Usage Guides](https://redux.js.org/usage/index) - [FAQ](https://redux.js.org/faq) - [API Reference](https://redux.js.org/api/api-reference) ## Learn Redux ### Redux Essentials Tutorial The [**Redux Essentials tutorial**](https://redux.js.org/tutorials/essentials/part-1-overview-concepts) is a "top-down" tutorial that teaches "how to use Redux the right way", using our latest recommended APIs and best practices. We recommend starting there. ### Redux Fundamentals Tutorial The [**Redux Fundamentals tutorial**](https://redux.js.org/tutorials/fundamentals/part-1-overview) is a "bottom-up" tutorial that teaches "how Redux works" from first principles and without any abstractions, and why standard Redux usage patterns exist. ### Additional Tutorials - The Redux repository contains several example projects demonstrating various aspects of how to use Redux. Almost all examples have a corresponding CodeSandbox sandbox. This is an interactive version of the code that you can play with online. See the complete list of examples in the **[Examples page](https://redux.js.org/introduction/examples)**. - Redux creator Dan Abramov's **free ["Getting Started with Redux" video series](https://app.egghead.io/playlists/fundamentals-of-redux-course-from-dan-abramov-bd5cc867)** and **[Building React Applications with Idiomatic Redux](https://egghead.io/courses/building-react-applications-with-idiomatic-redux)** video courses on Egghead.io - Redux maintainer Mark Erikson's **["Redux Fundamentals" conference talk](https://blog.isquaredsoftware.com/2018/03/presentation-reactathon-redux-fundamentals/)** and [**"Redux Fundamentals" workshop slides**](https://blog.isquaredsoftware.com/2018/06/redux-fundamentals-workshop-slides/) - Dave Ceddia's post [**A Complete React Redux Tutorial for Beginners**](https://daveceddia.com/redux-tutorial/) ### Other Resources - The **[Redux FAQ](https://redux.js.org/faq)** answers many common questions about how to use Redux, and the **["Using Redux" docs section](https://redux.js.org/usage/index)** has information on handling derived data, testing, structuring reducer logic, and reducing boilerplate. - Redux maintainer Mark Erikson's **["Practical Redux" tutorial series](https://blog.isquaredsoftware.com/series/practical-redux/)** demonstrates real-world intermediate and advanced techniques for working with React and Redux (also available as **[an interactive course on Educative.io](https://www.educative.io/collection/5687753853370368/5707702298738688)**). - The **[React/Redux links list](https://github.com/markerikson/react-redux-links)** has categorized articles on working with [reducers and selectors](https://github.com/markerikson/react-redux-links/blob/master/redux-reducers-selectors.md), [managing side effects](https://github.com/markerikson/react-redux-links/blob/master/redux-side-effects.md), [Redux architecture and best practices](https://github.com/markerikson/react-redux-links/blob/master/redux-architecture.md), and more. - Our community has created thousands of Redux-related libraries, addons, and tools. The **["Ecosystem" docs page](https://redux.js.org/introduction/ecosystem)** lists our recommendations, and also there's a complete listing available in the **[Redux addons catalog](https://github.com/markerikson/redux-ecosystem-links)**. ### Help and Discussion The **[#redux channel](https://discord.gg/0ZcbPKXt5bZ6au5t)** of the **[Reactiflux Discord community](https://www.reactiflux.com)** is our official resource for all questions related to learning and using Redux. Reactiflux is a great place to hang out, ask questions, and learn - please come and join us there! ## Before Proceeding Further Redux is a valuable tool for organizing your state, but you should also consider whether it's appropriate for your situation. Please don't use Redux just because someone said you should - instead, please take some time to understand the potential benefits and tradeoffs of using it. Here are some suggestions on when it makes sense to use Redux: - You have reasonable amounts of data changing over time - You need a single source of truth for your state - You find that keeping all your state in a top-level component is no longer sufficient Yes, these guidelines are subjective and vague, but this is for a good reason. The point at which you should integrate Redux into your application is different for every user and different for every application. > **For more thoughts on how Redux is meant to be used, please see:**

His goal was to create a state management library with a minimal API but completely predictable behavior. Redux makes it possible to implement logging, hot reloading, time travel, universal apps, record and replay, without any buy-in from the developer. ## Influences Redux evolves the ideas of [Flux](https://facebook.github.io/flux/), but avoids its complexity by taking cue
