Summary  
This chapter explains how to manage global application state using Redux Toolkit by creating a central store, defining slices, dispatching updates from multiple components, and handling asynchronous operations with loading and error states.

General domain of usage  
Front-end web applications

In this course, you will build a small application that uses Redux Toolkit to manage global state. The goal is not the complexity of the app, but how state is handled across different parts of it.

You will create a central store, define slices, update state from multiple components, and handle async data. By the end, you will see how everything connects into a single, predictable flow.

The app will include features like creating, updating, and removing data, along with loading and error states for async operations.


Opdag styrken ved Redux Toolkit i samspil med React, og styrk dine færdigheder inden for state management. Dette kursus giver en omfattende introduktion til Redux Toolkit, et kraftfuldt bibliotek til håndtering af state. Lær at forenkle din Redux-opsætning, simplificere kompleks state-logik og skabe effektive, skalerbare 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.
