Getting Started with Redux in Next.js

If youre new to building web applications with React, you may be wondering how to manage the state of your application. One popular solution is to use Redux, a library that allows you to centralize your applications state and manage it in a predictable and organized way. In this article, we'll go over the basics of using Redux in a Next.js application, including setting up the store, configuring reducers, and connecting the store to your components. By the end of this guide, you will have a better understanding of how to use Redux to manage the state of your Next.js application.

To start using Redux in a Next.js application, you'll first need to install the necessary packages. Open your terminal and run the following command to install the redux and react-redux packages:

npm install redux react-redux

Once the packages are installed, you can create a new file in your project's directory called store.js to set up the store. In this file, you'll need to import the createStore function from the redux package and configure it with your reducers and any necessary middleware.

Here's an example of a basic store configuration:

import { createStore } from 'redux'
import rootReducer from './reducers'

const store = createStore(rootReducer)

export default store

In the example above, we're importing the createStore function and a rootReducer that we'll create in the next step. The createStore function takes in the rootReducer as its argument and returns the store.

Now you need to create the reducers folder and inside it, create a index.js file. Here is an example of a simple reducer:

const initialState = {
  count: 0,

function counterReducer(state = initialState, action) {
  switch (action.type) {
    case 'INCREMENT':
      return {
        count: state.count + 1,
    case 'DECREMENT':
      return {
        count: state.count - 1,
      return state

export default counterReducer
