Create Express Server in NodeJS

Hey guys in this post, we will discuss about creating Express Server in Node.js with just 5 simple steps.

What is Express?

Express.js or simply Express is a light-weight web application framework to help organize your web application into an MVC architecture on the server side. We can use a variety of choices for our templating language (like EJS, Jade, and Dust.js). It is designed for building REST APIs. It has been called the de facto standard server framework for Node.js.

Steps to Create Express Server

Following are the steps to create Express Server in Node.js

Create empty directory

Open the command prompt and enter the following command to create empty directory

mkdir web-servers

Initialize the npm

On the root of our directory, open the command prompt and enter the following command to initialize the npm

npm init -y

This will generate package.json file on the root of your directory, which contains the app information and dependencies.

  "name": "web-servers",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  "keywords": [],
  "author": "",
  "license": "ISC"

Install Express

On the root of our directory, open the command prompt and enter the following command to install Express

npm i express

This will install the Express and added to the dependencies section inside the package.json file

Create Express Server

On the root of our directory, create a file app.js and add the following code

const express = require('express');

const app = express();

app.get('', (req, res) => {
    res.send('<h1>Hello Express!</h1>');

app.listen(3000, () => {
    console.log('Server is up and running');
  • At the top we will load the library express using require() method
  • We will create the express server using express() method
  • We will return <h1> content to the default route
  • We will start the express server by calling listen() method

Test the app

Open the browser and navigate to the URL localhost:3000, we will see the following text
