Summary  
This chapter explains how to install Redux Toolkit and React-Redux, create a Redux store using `configureStore`, and integrate it into a React application by wrapping the root component with `Provider` so that the store is available throughout the app.

General domain of usage  
State management in React applications

To start using Redux Toolkit, you need to install it along with the React bindings.

Run the following command in your project:

```bash
npm install @reduxjs/toolkit react-redux
```

This installs everything you need to create a store and connect it to your React app.





## Setting Up the Store

Create a new file for the store. A common location is:

```bash
src/store/store.js
```

Inside this file, you create the store using `configureStore`:

```javascript
import { configureStore } from '@reduxjs/toolkit';

export const store = configureStore({
  reducer: {}
});
```

At this point, the store is empty. You will add reducers to it in the next chapters.





## Connecting Redux to React

To make the store available in your app, wrap your root component with `Provider`.

Open your main entry file (for example `main.jsx` or `index.js`) and update it like this:

```javascript
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>
);
```

Now the Redux store is available in every component.

Entdecken Sie die Leistungsfähigkeit von Redux Toolkit in Verbindung mit React und verbessern Sie Ihre Fähigkeiten im Bereich State Management. Dieser Kurs bietet eine umfassende Einführung in Redux Toolkit, eine leistungsstarke Bibliothek zur Verwaltung von Zustand. Lernen Sie, wie Sie Ihre Redux-Konfiguration optimieren, komplexe Zustandslogik vereinfachen und effiziente, skalierbare React-Anwendungen erstellen.

Understand why Redux Toolkit exists and when it becomes useful. Recognize how state complexity grows in real applications and why simple approaches stop scaling.

Install Redux Toolkit and set up the store. Connect Redux to a React application and understand how data flows through the system.

Define state using slices and organize logic clearly. Create reducers, use generated actions, and keep state manageable as the application grows.

Read data from the store using useSelector and update it with useDispatch. Structure state correctly and avoid common mistakes when working with shared data.

Fetch data from APIs using createAsyncThunk. Manage loading and error states and keep the UI in sync with async updates.

Split state into multiple slices and organize files by feature. Combine reducers cleanly and maintain a clear structure as the application grows.

Build a complete application using Redux Toolkit. Implement CRUD features, handle async data, and improve the user experience with loading and error states.
