How to Build an Application with ReactJS and NodeJS


In today’s world of development, the importance of React as a JavaScript library is well-known. Likewise, its combination with Node.js on the server-side can be used to yield a powerful combination. In this article, we shall primarily look at how one can build an application, making use of ReactJS on the front-end and Node.js on the backend.

Setup and Installation

In this section, we will discuss the setup of a full-stack environment. The front end part would be ReactJS and the back end would be NodeJS.

Installing ReactJS

First, we will check the simple steps to install the ReactJS front end tool. Open your working directory and run the following commands step by step. You can make any directory as your working directory. Please remember, the working directory should be a separate workspace where you install your environment and run your application.

  1. mkdir eduonix_react_example
  2. npm i -g create-react-app
  3. cd eduonix_react_example
  4. create-react-app eduonix_client
  5. cd client
  6. npm start

Following is the sample package.json created from the above configuration. In this example, we have used the listing port as 3001. You can use any other open port and modify the package.json file accordingly.

Listing 1: Sample package.json file

<pre class="lang:js decode:true">{
“name”: “eduonix_client”,
“version”: “0.1.0”,
“private”: true,
“proxy”: “http://localhost:3001/“,
“dependencies”: {
“react”: “16.8.6”,
“react-dom”: “16.8.6”,
“react-scripts”: “3.0.1”
“scripts”: {
“start”: “react-scripts start”,
“build”: “react-scripts build”,
“test”: “react-scripts test?-?env=jsdom”,
“eject”: “react-scripts eject”
<p align="justify">

Now, our React setup is complete. We can check it by opening the localhost at port 3000.

Installing NodeJS

Now, we will check step by step process to set up the NodeJS server. Here we will be using the Express framework. Please follow the steps below to install and run the NodeJS server.

  1. cd eduonix_react_example
  2. mkdir eduonix_server
  3. npm install express-generator -g
  4. express - - view=ejs server
  5. cd eduonix_server
  6. npm install
  7. Go to server folder (here eduonix_server)
  8. Open package.json file

The package.json will be as shown below. Here, we need to do a minor modification on the port number. We need to use some other port and not 3000.Because, our front end component React is running on port 3000. Let’s make it 3001 or any other. Now, the Node.JS set up is ready for connecting.

Listing 2: Sample package.json file (for NodeJS server)

“name”: “eduonix_server”,
“version”: “0.0.0”,
“private”: true,
“scripts”: {
“start”: “nodemon ./bin/www”
“dependencies”: {
“cookie-parser”: “~1.4.3”,
“debug”: “~2.6.9”,
“ejs”: “~2.5.7”,
“express”: “~4.16.0”,
“http-errors”: “~1.6.2”,
“morgan”: “~1.9.0”,
“nodemon”: “¹.17.5”
“main”: “app.js”,
“devDependencies”: {},
“keywords”: [],
“author”: “Eduonix”,
“license”: “ISC”,
“description”: “”

Connecting ReactJS and NodeJS

In this section, we will connect the front end with the back-end server. Please follow the steps below to connect ReactJS with the Node server.

  1. Go to eduonix_react_example
  2. npm init –y
  3. Now a separate package.json file will be created outside server and client folder

The package.json file will look like this.

Listing 3: Sample package.json file (for connecting node server)

<pre class="lang:js decode:true">{
“name”: “connect_node”,
“version”: “1.0.0”,
“description”: “”,
“main”: “index.js”,
“scripts”: {
“client”: “cd eduonix_client &amp;&amp; npm start”,
“server”: “cd eduonix_server &amp;&amp; npm start”,
“start”: “concurrently?-?kill-others \”npm run eduonix_server\" \"npm run eduonix_client\""
“keywords”: [],
“author”: “Eduonix”,
“license”: “ISC”,
“devDependencies”: {
“concurrently”: “³.5.1”
<p align="justify">

Now our ReactJS and NodeJS are up and running on port 3000 and 3001. So, you can connect the front end and back end to create various applications.


React and NodeJS is definitely a powerful combination, and that is exactly what has been demonstrated in this article. It gives you a basic idea about what React and NodeJS is and takes you through a sample application to help you get familiar with the concepts. You can also learn more about connecting a React App with Nodejs and how to become a React developer.

How to Hire Full Stack Developer for Reactjs and Nodejs Project

Read here how to hire full stack developer for the project.

We are all the big fans of Netflix — prime video content directly into your Gadget. You will feel the outstanding UI experience in the web app of Netflix and Netflix is powerful enough to deliver 10 billion hours of prime video content to over 190 million users every day.

Surprising, isn’t it?

One of the reasons behind such a surprising success of Netflix is the combination of Reactjs and Nodejs which boost the performance and scalability of Netflix. But to make things happen, first of all, you need to hire full stack developer who is capable of fulfilling your requirements and needs.

Today, I’m here with the wonderful article, in this article I will explain you need to go for the combination of Nodejs and Reactjs for your project and why you need to hire Reactjs/Nodejs full stack developer, and how it can be a better option for you than hiring two separate experts, and at last I’m also going to share some important tips which going to help you to hire dedicated full stack developer.

Let’s quickly understand — full-stack developer

You might be well aware that every web and mobile application has two parts — one is the back end which is known as the server-side and the second one is the front end — which is known as the client-side. In short, what users actually can see and interact with is known as the front end and the back end is server, database, and application data.

When you are a front-end or back-end developer — you only have skills to develop any of the one sides only, but a full stack developer can have the skills of handling both sides. That means they are the perfect set of developers that need the projects.

For successful implementations of the project, you need to hire full stack engineer which is capable enough to translate your project requirements into the overall architecture.

What so need to combine Reactjs and Nodejs?

Being Facebook’s product — Reactjs is used to build the high scalable front-end development and it is an open-source JavaScript library. You will get lots of dynamic features and input in Reactjs. With the help of Reactjs, you can develop the front-end where users can interact with each other and share the feeds.

Let’s have a look at the advantages of Reactjs

  • Maintenance will be smooth and easy due to reusable components
  • You will get high performance due to virtual DOM
  • TypeScript support
  • code stability

So, you can see how brilliantly Reactjs can handle your front-end. Now for the back-end, you need Nodejs — an open-source and JavaScript framework.
