In JavaScript projects, Redux is a commonly used state management library. However, setting up Redux and managing its boilerplate code can be cumbersome and time-consuming. That’s where Redux Toolkit comes in handy.

What is Redux Toolkit?

Redux Toolkit is the official recommended way to write Redux logic. It is a set of opinionated tools and utilities that simplifies the process of creating, configuring, and managing Redux stores. It helps reduce boilerplate code and makes Redux development more efficient.

Step-by-step guide for setting up Redux Toolkit

Step 1: Install Redux Toolkit

Start by installing Redux Toolkit into your project. You can do this using npm or yarn:

npm install @reduxjs/toolkit

or

yarn add @reduxjs/toolkit

Step 2: Create a Redux Slice

A Redux slice represents a specific part of your Redux state and contains the actions and reducers associated with that part. Create a new file called counterSlice.js and define your first Redux slice.

// counterSlice.js

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

const counterSlice = createSlice({
  name: 'counter',
  initialState: 0,
  reducers: {
    increment: (state) => state + 1,
    decrement: (state) => state - 1,
  },
});

export const { increment, decrement } = counterSlice.actions;
export default counterSlice.reducer;

Step 3: Create a Redux Store

Create a Redux store using the configureStore function provided by Redux Toolkit. Import the created reducer from the slice file and pass it as an argument to configureStore.

// store.js

import { configureStore } from '@reduxjs/toolkit';
import counterReducer from './counterSlice';

const store = configureStore({
  reducer: {
    counter: counterReducer,
  },
});

export default store;

Step 4: Connect Redux Store to the App

To use the Redux store in your application, wrap your root component with the Provider component from the react-redux library. Import the store and wrap your app.

// index.js

import React from 'react';
import { Provider } from 'react-redux';
import store from './store';
import App from './App';

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

That’s it! You have successfully set up Redux Toolkit in your JavaScript project. Now, you can start using the increment and decrement actions provided by your counter slice to manage the state.

Remember to import the necessary functions, components, and files as shown in the code examples.
