how to use redux in react js

To use Redux in a React app, you can follow these basic steps:

Install the required packages by running the following command in your terminal: 

npm install redux react-redux

Create a Redux store by creating a store.js file in your project's root directory. In this file, you can define your initial state and any reducers that you want to use.

import { createStore } from 'redux'

const initialState = { // Define your initial state here }; 

function reducer(state = initialState, action) { // Define your reducers here }

 const store = createStore(reducer); 

export default store;

Wrap your app in a Provider component, which comes from the react-redux package. This makes the Redux store available to all components in your app.

 

import React from 'react'

import ReactDOM from 'react-dom';

 import { Provider } from 'react-redux'

import store from './store';

 import App from './App';

 ReactDOM.render(

 <Provider store={store}

<App />

 </Provider>,

 document.getElementById('root') );

Use the connect function from react-redux to connect your components to the Redux store. This allows you to access state and dispatch actions from within your components.

import React from 'react';

 import { connect } from 'react-redux'

function MyComponent(props) {

 return <div>{props.myValue}</div>; } 

function mapStateToProps(state) { 

return { myValue: state.myValue, }; 

} export default connect(mapStateToProps)(MyComponent);

These are the basic steps for using Redux in a React app. Of course, there are many other features and concepts that you can explore as you become more familiar with Redux.
