React.js has become one of the most popular JavaScript libraries for building user interfaces. Its component-based architecture and virtual DOM make it a powerful tool for creating dynamic and interactive web applications. In this article, we will explore how to create a full stack application using React.js.

What is a Full Stack Application?

A full stack application refers to a software application that consists of both a front-end and a back-end. The front-end is responsible for the user interface and user experience, while the back-end handles the server-side logic and data storage. Creating a full stack application allows you to build end-to-end solutions that can handle complex business requirements.

Setting Up the Back-end

Before we dive into building the front-end with React.js, we need to set up the back-end. For this tutorial, we will use Node.js and Express.js to create a RESTful API.

  1. Start by creating a new directory for your project and navigate to it in your terminal.
  2. Initialize a new Node.js project by running the command npm init.
  3. Install Express.js by running npm install express.
  4. Create a new file called server.js and require Express.js at the top of the file.
  5. Set up a basic Express.js server and define your API routes.
  6. Test your server by running node server.js in your terminal.

Building the Front-end with React.js

Now that we have our back-end set up, let’s move on to building the front-end with React.js. To get started, make sure you have Node.js and npm installed on your machine.

  1. Create a new directory for your React.js project and navigate to it in your terminal.
  2. Initialize a new React.js project by running the command npx create-react-app my-app.
  3. Navigate to the newly created directory my-app by running cd my-app.
  4. Start the development server by running npm start.
  5. Open your browser and visit http://localhost:3000 to see your React.js application running.

Connecting the Front-end and Back-end

Now that we have both the front-end and back-end set up, we need to connect them together. This can be done by making API requests from the React.js application to the Express.js server.

In your React.js project, you can use libraries like Axios or the built-in Fetch API to make HTTP requests. You can fetch data from your Express.js API endpoints and update the UI accordingly.

Here’s an example of how you can make a GET request to retrieve data from your Express.js API:

    import React, { useEffect, useState } from 'react';
    import axios from 'axios';

    function App() {
      const [data, setData] = useState([]);

      useEffect(() => {
          .then(response => {
          .catch(error => {
      }, []);

      return (
          { => (
            <div key={}>{}</div>

    export default App;

Make sure to replace /api/data with your actual API endpoint. You can also make POST, PUT, and DELETE requests to update data on the server.

Deploying Your Full Stack Application

Once you have finished building your full stack application, you can deploy it to a hosting provider of your choice. There are many options available, such as Heroku, AWS, and Netlify.

Before deploying, make sure to build your React.js application by running the command npm run build. This will create an optimized production build of your application.

After building your React.js application, you can deploy both the front-end and back-end to your hosting provider. Make sure to configure any necessary environment variables and update your API endpoints accordingly.


Creating a full stack application with React.js allows you to build powerful and scalable web applications. By combining the front-end and back-end, you can create end-to-end solutions that handle complex business requirements. With the steps outlined in this article, you should now have a good understanding of how to create a full stack application using React.js.
