Getting Started with React Redux

React Redux is the official React UI bindings layer for Redux. It lets your React components read data from a Redux store, and dispatch actions to the store to update state.

Installation​

React Redux 8.x requires React 16.8.3 or later / React Native 0.59 or later, in order to make use of React Hooks.

Create a React Redux App​

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

We do not currently have official React Native templates, but recommend these templates for standard React Native and for Expo:

An Existing React App​

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

# If you use npm:
npm install react-redux

# Or if you use Yarn:
yarn add react-redux

You'll also need to install Redux and set up a Redux store in your app.

React-Redux v8 is written in TypeScript, so all types are automatically included.

API Overview​

Provider​

React Redux includes a <Provider /> component, which makes the Redux store available to the rest of your app:

import React from 'react'
import ReactDOM from 'react-dom/client'

import { Provider } from 'react-redux'
import store from './store'

import App from './App'

// As of React 18
const root = ReactDOM.createRoot(document.getElementById('root'))
root.render(
  <Provider store={store}>
    <App />
  </Provider>
)

Hooks​

React Redux provides a pair of custom React hooks that allow your React components to interact with the Redux store.

useSelector reads a value from the store state and subscribes to updates, while useDispatch returns the store's dispatch method to let you dispatch actions.

import React from 'react'
import { useSelector, useDispatch } from 'react-redux'
import {
  decrement,
  increment,
  incrementByAmount,
  incrementAsync,
  selectCount,
} from './counterSlice'
import styles from './Counter.module.css'

export function Counter() {
  const count = useSelector(selectCount)
  const dispatch = useDispatch()

  return (
    <div>
      <div className={styles.row}>
        <button
          className={styles.button}
          aria-label="Increment value"
          onClick={() => dispatch(increment())}
        >
          +
        </button>
        <span className={styles.value}>{count}</span>
        <button
          className={styles.button}
          aria-label="Decrement value"
          onClick={() => dispatch(decrement())}
        >
          -
        </button>
      </div>
      {/* omit additional rendering output here */}
    </div>
  )
}

Learning React Redux​

Learn Modern Redux Livestream​

Redux maintainer Mark Erikson appeared on the "Learn with Jason" show to explain how we recommend using Redux today. The show includes a live-coded example app that shows how to use Redux Toolkit and React-Redux hooks with Typescript, as well as the new RTK Query data fetching APIs.

See the "Learn Modern Redux" show notes page for a transcript and links to the example app source.
