React Frontend with Node Backend – Node.js Tutorial 20
In this tutorial, we will be covering how to create a React frontend and a Node backend using Node.js. React is a popular JavaScript library for building user interfaces, and Node.js is a runtime environment that allows you to run JavaScript on the server side. By combining these two technologies, we can create a powerful and efficient web application.
Setting Up The Node Backend
First, we need to set up the Node backend of our application. We can do this by creating a new directory for our project and running the following command to initialize a new Node.js project:
npm init -y
This will create a package.json file with default values. We can then install the necessary dependencies for our backend using the following command:
npm install express body-parser
We can now create a new file called server.js and set up our Node backend using the Express.js framework. We can create a simple endpoint that returns a JSON response like this:
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const port = 3000;
app.use(bodyParser.json());
app.get('/api/data', (req, res) => {
res.json({ message: 'Hello from the Node backend!' });
});
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
Creating The React Frontend
Next, we can create the React frontend of our application. We can do this by running the following command to create a new React project:
npx create-react-app frontend
This will create a new directory called frontend with all the necessary files for our React application. We can then cd into the frontend directory and start the development server using the following command:
npm start
We can now create a new file called App.js and make a request to our Node backend using the fetch API. We can then display the response in our React frontend like this:
import React, { useState, useEffect } from 'react';
function App() {
const [data, setData] = useState('');
useEffect(() => {
fetch('/api/data')
.then(response => response.json())
.then(data => setData(data.message));
}, []);
return (

{data}
);
}
export default App;
Conclusion
In this tutorial, we have covered how to create a React frontend and a Node backend using Node.js. By combining these two technologies, we can create a powerful and efficient web application. We have also demonstrated how to make a request to the Node backend from our React frontend and display the response. We hope this tutorial has been helpful to you in understanding how to create a full stack web application using React and Node.js.

Hey Caleb Thank you so much for the great content ! Could You Please Tell Me If We Could Specify The same port and domain for the react app and node.js ? Again Thank You So Much !
I love this series thank you so much
You are a great teacher man. thank you for delivering these programming tutorials and making it easier for us beginners to learn and understand how these things work
