When To Use React with Node JS?

There are certain cases when working with this magnificent pair- Node and React- will work wonders for you. When your project requirements match the criteria below, use React with Node js under such conditions and circumstances.

Use Node JS with React JS

High Server-load

React, and Node is the best combination if your application needs to handle multiple requests and maintain a high server-load balance.

Real-time data

If your business application deals with real-time data management or aspires to develop a data streaming application, I recommend using Node.js because your application needs continued server connection.


With React JS, you get high code reusability and easy code sharing ability. As you need to develop Javascript Object Notation API, Node JS enables that very efficiently.

Single-page Applications

If your business needs a single-page application SPA with asynchronous data loading, then you have to choose React app with Node back-end because it enables you to make a lightweight back-end model via callback functions.

MERN stack

As you have planned to follow the MERN stack, you should use React and Node along with MongoDB and Express.

React With Node Tech Tutorial

This tech tutorial illustrates how to create React app with Node js.

You can connect with our full-stack developer to build an application that generates revenue and makes the user experience unforgettable.

So, let’s understand how an application is built.

Step 1: Create your development environment

For setting up a development environment, you need to install Node.js and a code editor, such as Sublime Text or Visual Studio Code.

Step 2: Create a new React application

Use the create-react-app CLI tool to create a new react application. For this, you must run the following command in your terminal

Copy Text
npx create-react-app my-app

Step 3: Install mandatory dependencies

Now that you have created a new React application, it’s time to install the essential dependencies. Run the following command in your terminal and you are all set up with the dependencies.

Copy Text
cd my-app
npm install

Step 4: Create a Node.js server

Here, you have to create a new file called “server.js” in the root directory of your project file. Under this, create a Node JS server using the “express” package. For this, run the following command.

Copy Text
npm install express

Step 5: Connect your React app with the Node server

To fetch data with your React app, create an API on your Node.js server. For cross-origin requests from your React to Node server, use the “cors” package. createRun the following command to install the “cors” package.

Copy Text
npm install cors

Step 6: Build your React app

You must build your React app before serving up from your Node.js server. For this, you have to run the following command.

Copy Text
npm run build

Step 7: Use Node.js to serve your application

Your React app is built. Now you can serve the application from your Node.js server. Now add the following command to your “server.js” file.

Copy Text
const express = require('express');
const cors = require('cors');

const app = express();


app.listen(3000, () => {
  console.log('App listening on port 3000');

Step 8: Test your React & Node-built application

Now that your app is ready, it’s time to test your application. Run the following command into your terminal to initiate the Node.js server.

Copy Text
node server.js

Now navigate to “http://localhost:3000”. Here you will see your React app running.

That’s how you will be able to create React app with Node js backend. Now you can add functionalities with the help of creating new components.

React with Node JS Case Study

Here, I have shared one of our client’s successful case study where we used Node with React JS to attain their project expectations. Read the case study below.

React with Node JS Case Study

Project Idea: Document Sign and Share App


Our client wanted to have a document signing and sharing application, where each recipient can put their signatures or initials or emails or name or dates or any custom text on the document and resend the document in PDF format.

Client Requirements

Our client was very particular that he wanted an interactive and user-friendly UI for this multiple Document sign and share application.


Some of the challenges that we faced while developing this app were:

  • Accommodating multiple recipients’ signatures in PDF
  • Standalone API
  • Drag and Drop feature for custom signatures
  • Replacing a signature on the document with a textual code on the file
  • Send signed document email to the receiver and update in the application

Our Solution Approach using ReactJS and Node JS:

  • React Redux state management.
  • We enabled multithreading in the back-end by running the Node server and Socket server on a single port.
  • We used the Node package library- hummus-recipe for putting signatures/images/custom text to their exact position in the PDF.
  • We developed a custom mathematical logic for calculating the pixels by pixel-perfect positions to put images/signs/initials/custom text etc.
  • Standalone approach: We approached AWS textract instead of Google vision and Tesseract [Open source], for better accuracy, and it’s 90% accurate to detect our embedded codes with font size around 10 to 23.
  • Successfully used socket server and node server.

Successful Project Features:

  • Dynamic Type Changing
  • Event-loop handling
  • Appropriate build-size
