Connecting Components to Redux

One of the key features of Redux is its ability to connect React components to the Redux store. This allows components to access the state stored in the Redux store and update the store by dispatching actions.

To connect a component to the Redux store, we can make use of the connect function from the react-redux package. This function creates a higher-order component that wraps the original component and connects it to the Redux store.

Here's an example of how to connect a component to the Redux store:

1// Import the necessary Redux functions
2import { connect } from 'react-redux';
3
4// Create a function to map the Redux state to props
5const mapStateToProps = (state) => {
6  return {
7    counter: state.counter
8  };
9};
10
11// Connect the component to Redux
12export default connect(mapStateToProps)(App);

xxxxxxxxxx

// Import the necessary Redux functions

import { connect } from 'react-redux';

​

// Create a function to map the Redux state to props

const mapStateToProps = (state) => {

  return {

    counter: state.counter

  };

};

​

// Connect the component to Redux

export default connect(mapStateToProps)(App);
