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

To use React-Redux with your React app:

bash
npm install --save react-redux

or

bash
yarn add react-redux

Provider and connect

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

js
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,
)

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

Normally, you’ll call connect in this way:

js
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)
