Overview of Redux Toolkit 

Get an in-depth overview of Redux Toolkit, a powerful tool for managing state in React applications. Simplify your development process efficient management.

What is Redux Toolkit

Redux Toolkit is a recommended toolset for efficient Redux development. It simplifies the process of setting up a Redux store, reduces boilerplate code, and provides powerful utilities for common Redux use cases. It integrates with the existing Redux library but streamlines many aspects of state management. Here are some key features:

Key Features:

1. configureStore: Streamlines store configuration by automatically enforcing best practices, such as merging reducers, integrating middleware (e.g., redux-thunk), and activating Redux DevTools.
2. createSlice: Merges the process of defining a portion of the Redux state, action creators, and reducers into a single function. This simplifies the management of various sections of your application’s state.
3. createAsyncThunk: Provides a way to handle asynchronous logic in Redux, such as API calls, without manually writing extra action types or dispatch logic.
4. createEntityAdapter: Provides pre-built reducers and selectors to manage normalized state, which is useful when working with collections of data (e.g., lists of items).

 

Advantages:

1. Boilerplate Reduction: It removes a lot of the redundant code commonly linked with Redux, such as action creators and switch statements in reducers.
2. Consistency: Encourages consistent patterns and best practices in Redux development.
3. Out-of-the-box Solutions: Common practices such as handling asynchronous operations or managing data collections are managed effectively.

 

Example of Redux Toolkit with React

Step1: Install the dependencies

npm install @reduxjs/toolkit react-redux

 

Step2: Create a redux slice counterslice

In this slice, we define the counter’s state and the increment and decrement actions.

import { createSlice } from ‘@reduxjs/toolkit’; 

const counterSlice = createSlice(

{ 

name: ‘counter’, initialState: { value: 0, }, 

reducers: { 

increment: (state) => { state.value += 1; }, 

decrement: (state) => { state.value -= 1; }, 

},

 }

); 

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

export default counterSlice.reducer;

 

 

Step 3: Configure the store

Create a Redux store and add the counter reducer from counterSlice.

// src/app/store.js 

import { configureStore } from ‘@reduxjs/toolkit’; 

import counterReducer from ‘../features/counter/counterSlice’; 

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

 

Step 4: Set Up the React App

Wrap your application in the Redux Provider so it has access to the store.

// src/index.js 

import React from ‘react’; 

import ReactDOM from ‘react-dom/client’;

 import ‘./index.css’; 

import App from ‘./App’; 

import { Provider } from ‘react-redux’; 

import { store } from ‘./app/store’; 

const root = ReactDOM.createRoot(document.getElementById(‘root’)); root.render( <Provider store={store}> <App /> </Provider> )

 

Step 5: Create the Counter Component

Use the useDispatch and useSelector hooks to interact with the Redux store.

// src/App.js

 import React from ‘react’; 

import { useDispatch, useSelector } from ‘react-redux’; 

import { increment, decrement } from ‘./MyApp/counter/counterSlice’; function App() { 

const count = useSelector((state) => state.counter.value); 

const dispatch = useDispatch(); 

return ( <div> <h1>Counter: {count}</h1> 

<button onClick={() => dispatch(increment())}>Increment</button> 

<button onClick={() => dispatch(decrement())}>Decrement</button> </div> ); 

} 

export default App;

 

Conclusion

I have created a simple, straightforward example of using the Redux Toolkit to manage a simple counter-state in a React app. Which will demonstrate the use of redux-toolkit to efficiently develop the react-redux application.
