Quick Start

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.

Installation

React Redux 7.x requires React 16.8.3 or later.

To use React Redux with your React app:

npm install react-redux

or

yarn add react-redux

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

Provider

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

import React from 'react'

import ReactDOM from 'react-dom'

import { Provider } from 'react-redux'

import store from './store'

import App from './App'

const rootElement = document.getElementById('root')

ReactDOM.render(

<Provider store={store}>

<App />

</Provider>,

rootElement

)

connect()

React Redux provides a connect function for you to connect your component to the store.

Normally, you’ll call connect in this way:

import { connect } from 'react-redux'

import { increment, decrement, reset } from './actionCreators'

// const Counter = ...

const mapStateToProps = (state /*, ownProps*/) => {

return {

counter: state.counter,

}

}

const mapDispatchToProps = { increment, decrement, reset }

export default connect(mapStateToProps, mapDispatchToProps)(Counter)
