Summary  
This chapter explains how Redux Toolkit automatically generates action creators from slice reducers and how to dispatch these actions to update the store state.

General domain of usage  
State management in JavaScript applications



When you create a slice, Redux Toolkit automatically generates actions for you. You don't need to define them manually.



## How Actions Are Created

Each reducer you define becomes an action.
For example, if you have:

```javascript
increment(state) {
  state.value += 1;
}
```

Redux Toolkit creates an action called `'counter/increment'`.


## Using Actions

You can import and use these actions in your components:

```javascript
import { increment } from './counterSlice';

dispatch(increment());
```

The action is sent to the store, and the corresponding reducer runs.



Ontdek de kracht van Redux Toolkit in combinatie met React en versterk uw vaardigheden in state management. Deze cursus biedt een uitgebreide introductie tot Redux Toolkit, een krachtige bibliotheek voor het beheren van state. Leer hoe u uw Redux-configuratie kunt vereenvoudigen, complexe state-logica kunt stroomlijnen en efficiënte, schaalbare React-toepassingen kunt creëren.

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.
