What is Redux Toolkit?

Redux Toolkit is a powerful and efficient library that simplifies managing the state in React applications using Redux. It provides a set of tools and best practices to streamline the development of complex state logic while maintaining scalability and readability.

In this article, we will cover the description of the Redux Toolkit, various approaches, and steps to create an application and provide an example to better understand Redux Toolkit.

Why You Should Use Redux Toolkit?

Redux Toolkit streamlines Redux development by implementing best practices, offering defaults, and simplifying code. It's beneficial for all Redux users, whether beginners or experienced users, and can be used in new projects or gradually integrated into existing ones. While not mandatory, Redux Toolkit is highly recommended for improving code quality and maintainability.

configureStore():

This approach utilizes the configureStore function provided by Redux Toolkit to create a Redux store with a built-in middleware setup and additional enhancements.

createSlice():

The createSlice function allows developers to define a slice of the Redux state along with its associated actions and reducers, reducing the need for multiple files.

createAsyncThunk():

For handling asynchronous actions, Redux Toolkit introduces createAsyncThunk which simplifies the process of dispatching async actions and handling loading, success, and error states.

Steps to Implement Redux Toolkit

Step 1: Create a new app using the following command in your terminal.

npx create-react-app redux-todo-app

Step 2: Navigate to the root directory of your application.

cd redux-todo-app

Step 3: Install Redux Toolkit and React-Redux:

npm install @reduxjs/toolkit react-redux
