Redux Toolkit Quick Start


It was first introduced to the front-end world in 2015 by Dan Abramov and Andrew Clark as a revolutionary state management library. It is now one of the most popular state management libraries on the web.
Redux is a front-end component state management system, which makes managing multiple component states easier for complex apps. React, Angular, or Vue provide components that internally manage their own states.

Redux Toolkit

I have used the Redux toolkit in my projects. Because it is easy to use and It is also easily maintainable and scalable . Also, there are many other benefits such as efficient testing, easy debugging and better performance that Redux brings to the table.

Redux Toolkit Installation

Step 1: install packages

Create a React Redux App

npx create-react-app my-app --template redux
Enter fullscreen mode Exit fullscreen mode

Add the Redux Toolkit and React-Redux packages to your existing project:

npm install @reduxjs/toolkit react-redux
Enter fullscreen mode Exit fullscreen mode

Step 2: Create a Redux Store​

Create a file named src/redux/store.js. Import the configureStore API from Redux Toolkit. We'll start by creating an empty Redux store, and exporting it:

import { configureStore } from '@reduxjs/toolkit'

export const store = configureStore({
  reducer: {},

Enter fullscreen mode Exit fullscreen mode

Step 3: Provide the Redux Store to React

Once the store is created, we can make it available to our React components by putting a React-Redux around our application in src/index.js. Import the Redux store we just created, put a around your , and pass the store as a prop:

import React from 'react'
import ReactDOM from 'react-dom'
import './index.css'
import App from './App'
import { store } from './app/store'
import { Provider } from 'react-redux'

  <Provider store={store}>
    <App />

Enter fullscreen mode Exit fullscreen mode

Step 4: Create a Redux State Slice

Create a file named src/redux/slices/foodSlice.js.

import { createSlice } from '@reduxjs/toolkit'

const initialState = {
  value: 0,

export const counterSlice = createSlice({
  name: 'counter',
  reducers: {
    increment: (state) => {
      // Redux Toolkit allows us to write "mutating" logic in reducers. It
      // doesn't actually mutate the state because it uses the Immer library,
      // which detects changes to a "draft state" and produces a brand new
      // immutable state based off those changes
      state.value += 1
    decrement: (state) => {
      state.value -= 1
    incrementByAmount: (state, action) => {
      state.value += action.payload

// Action creators are generated for each case reducer function
export const { increment, decrement, incrementByAmount } = counterSlice.actions

export default counterSlice.reducer

Enter fullscreen mode Exit fullscreen mode

Step 5: Add Slice Reducers to the Store

On the src/redux/store.js path add Slice reducers to the store

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

export const store = configureStore({
  reducer: {
    counter: counterReducer,

Enter fullscreen mode Exit fullscreen mode
