How to Integrate React Context with Redux for State Management

State management is a crucial aspect of building robust and scalable React applications. React Context and Redux are two popular state management libraries that can be used together to manage state in React applications.

What is React Context?

React Context is a built-in state management library in React that allows you to share state between components without passing props down manually. It provides a way to share data between components that are not directly related to each other.

What is Redux?

Redux is a popular state management library that helps you manage global state by providing a single source of truth for state. It provides a predictable and scalable way to manage state in complex applications.

Why Integrate React Context with Redux?

Integrating React Context with Redux provides a powerful way to manage state in React applications. React Context provides a way to share state between components, while Redux provides a single source of truth for state. By integrating both libraries, you can create a robust and scalable state management system.

Step 1: Create a New React App

Create a new React app using create-react-app:

npx create-react-app my-app

Step 2: Install Redux and React Context

Install Redux and React Context using npm or yarn:

npm install redux react-redux

Step 3: Create a Redux Store

Create a new file called `store.js` and add the following code:

import { createStore, combineReducers } from 'redux';

const initialState = {
  count: 0
};

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 };
    case 'DECREMENT':
      return { count: state.count - 1 };
    default:
      return state;
  }
};

const store = createStore(combineReducers({ reducer }));

export default store;

Step 4: Create a React Context

Create a new file called `context.js` and add the following code:

import { createContext, useState } from 'react';

const Context = createContext();

const Provider = ({ children }) => {
  const [count, setCount] = useState(0);

  return (
    
      {children}
    
  );
};

export { Context, Provider };

Step 5: Integrate Redux with React Context

Integrate Redux with React Context by wrapping the `Provider` component from React Context with the `Provider` component from Redux:

import React from 'react';
import ReactDOM from 'react-dom';
import { Provider as ReduxProvider } from 'react-redux';
import { Provider as ContextProvider } from './context';
import store from './store';

const App = () => {
  return (
    
      
        {/* Your app components here */}
      
    
  );
};

ReactDOM.render(, document.getElementById('root'));

Conclusion

In this tutorial, we learned how to integrate React Context with Redux for state management in React applications. We created a Redux store and a React Context, and integrated them together to create a robust and scalable state management system.
