Is Express Is a Web Server?

Is Express a Web Server?

When it comes to web development, understanding the different components and technologies involved is crucial. One commonly used technology is Express, a popular web application framework for Node.js. But what exactly is Express, and is it a web server?

The Basics

Express is not a web server in itself, but rather a framework that sits on top of Node.js and helps simplify the process of building web applications. It provides a set of tools and features that make it easier to handle HTTP requests, manage routes, and render views.

Express acts as a middleware layer between your application’s backend logic and the web server that handles incoming requests. It allows you to define routes and handle different types of requests, such as GET, POST, DELETE, etc.

Working with Web Servers

In order to run an Express application, you need to have a web server installed. While Express itself does not include a built-in server, it can be easily integrated with popular servers like Apache or Nginx.

When using Express with Node.js, you can create an HTTP server using the built-in ‘http’ module or use third-party libraries like ‘http-server’ or ‘nodemon’. These servers listen for incoming requests and pass them on to the Express framework for handling.

An Example

Let’s take a look at a simple example to better understand how Express works in conjunction with a web server:

const express = require('express');
const app = express();

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

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

In this example, we create an Express application and define a single route for the root URL (“/”). When a GET request is made to the root URL, the server responds with the message “Hello World!”. The server is set to listen on port 3000.


So, to summarize, while Express is not a web server itself, it is a powerful framework that helps simplify web development by providing an easy-to-use API for handling HTTP requests and managing routes. In order to run an Express application, you need to have a web server installed, which can be easily integrated with Node. By combining Express with a web server, you can build robust and scalable web applications.
