Redux Toolkit

Redux Toolkit is the official opinionated solution to write Redux logic. It provides a set of utilities and simplifications that make it easier to work with Redux for state management in your React applications.

Benefits of using Redux Toolkit

Redux Toolkit simplifies the following aspects of Redux state management:

• Reduces boilerplate code: Redux Toolkit reduces the amount of code needed to write common Redux patterns.

• Encourages best practices: Redux Toolkit enforces best practices for organizing and structuring your Redux code.

• Integrated tooling: Redux Toolkit includes built-in tools like the Redux DevTools Extension for debugging and inspecting your Redux state.

Getting Started with Redux Toolkit

To get started with Redux Toolkit, you need to install it via npm or yarn:

1npm install @reduxjs/toolkit

Here are a few examples of using Redux Toolkit:

• Importing createSlice function from Redux Toolkit

1import { createSlice } from '@reduxjs/toolkit';

• Importing configureStore function from Redux Toolkit

1import { configureStore } from '@reduxjs/toolkit';

• Defining a slice with createSlice

1const counterSlice = createSlice({
2  name: 'counter',
3  initialState: 0,
4  reducers: {
5    increment: (state) => {
6      state += 1;
7    },
8    decrement: (state) => {
9      state -= 1;
10    }
11  }
12});

• Configuring the Redux store with configureStore

1const store = configureStore({
2  reducer: {
3    counter: counterSlice.reducer
4  }
5});

By using Redux Toolkit, you can write Redux code more efficiently and follow best practices for managing state in your React applications.
