Introduction

Nodejs is JavaScript cross-platform runtime environment. When it comes to building a simple HTTP server for a project, building with nodejs, is simpler and lighter. This is because you don’t get to introduce external modules, built-in node modules.

This is a typical example of a node application:

1 const http = require( 'http') 2 3 const port = process. env.PORT 4 5 const server = http.createServer(( req, res) = > {

6   res. statusCode = 200

7   res.setHeader( 'Content-Type', 'text/html')

8   res. end( '

Hello, World!

9 }) 10 11 server.listen( port, () = > {

12    console.log(Server running at port ${ port})

13 })

In the code snippet above, we included Nodejs http module, which was used to create the HTTP server.

Yet, building a project requires more than setting up an HTTP server. You’ll have to handle routing, errors, parsing data, security, file uploads, and so much more. That’s where frameworks come in. Frameworks handle all these cases and more.

The most popular framework for building nodejs web applications is Express. Express offers really great syntax for routing HTTP requests, MVC like architecture, and it allows you easily setup middleware to respond to HTTP requests.

Let’s take a look at what our previous application might look like with Express.js:

1 const express = require( 'express');

2 const app = express();

3 app.get( '/', ( req, res) = > {

4      res.send( 'Hello World')

5 });

6 app.get( '/test', ( req, res) = > {

7      res.send( 'this is a different page')

8 })

9 app.listen(3000, () = > {

10    console.log( 'Server running at http://localhost:3000/');

11 });
