Connecting Redux to React with Provider

To use Redux inside your components, you need to connect your React app to the store.

This is done using the Provider component from 'react-redux'.

Wrapping the App

Open your main entry file, usually main.jsx or index.js, and wrap your app with Provider:

import React from 'react';
import ReactDOM from 'react-dom/client';
import { Provider } from 'react-redux';
import { store } from './store/store';
import App from './App';

ReactDOM.createRoot(document.getElementById('root')).render(
  <Provider store={store}>
    <App />
  </Provider>
);

What Provider Does

Provider makes the store available to the entire application. Once the app is wrapped, any component can access the state or dispatch actions without passing data through multiple layers.

Without Provider, your components would not know about the store. This connection is what allows Redux to work across the whole application instead of inside a single component.
