Integrating the Redux Store Into the React App
Practice
Once the store is configured, it can be used in the app. We have to provide the store
to the entire app. We will do it in the index.js
file.
import React from "react";
import ReactDOM from "react-dom/client";
import { Provider } from "react-redux";
import App from "./App/App";
import store from "./redux/store";
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
<Provider store={store}>
<React.StrictMode>
<App />
</React.StrictMode>
</Provider>
);
Code explanation: Integration of the Redux store into a React app using the react-redux
library. Let's break it down step by step.
- Line 3: Import the
Provider
component from thereact-redux
library; - Line 5: Import the
store
object from a file calledstore.js
, located in a folder calledredux
; - Line 9-13: The
Provider
component wraps theApp
component. TheProvider
component is a higher-order component provided byreact-redux
that makes the Redux store available to the components in the app; - Line 9: The
store
object is passed as a prop to theProvider
component. This prop is namedstore
, and its value is the importedstore
object.
1. What is the purpose of the Provider
component from the react-redux
library?
2. Which prop is used to provide the Redux store to the Provider
component?
