Summary  
This chapter covers how to organize code files by feature into dedicated folders to keep a growing project predictable and scalable.

General domain of usage  
Large-scale application development

As the number of slices grows, file structure becomes important.
A clear structure helps you navigate the project and keep everything predictable.


## Recommended Structure

A common approach is to group files by feature:

```bash
src/
  store/
    index.js
  features/
    user/
      userSlice.js
    tasks/
      tasksSlice.js
```



## The Idea

Each feature has its own folder, and everything related to it lives there.
This keeps your code organized and easy to scale as the app grows.





Without structure, files become scattered and hard to manage. A consistent layout makes it easier to find and update code.


Upptäck kraften i Redux Toolkit tillsammans med React och förbättra dina färdigheter inom tillståndshantering. Denna kurs ger en heltäckande introduktion till Redux Toolkit, ett kraftfullt bibliotek för hantering av tillstånd. Lär dig att effektivisera din Redux-konfiguration, förenkla komplex tillståndslogik och skapa effektiva, skalbara React-applikationer.

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.
