Node.js HTTP Module

Node.js HTTP Module

In this tutorial, we will learn about Node.js HTTP module and understand how out code working that we have written in Getting started with node.js.

Node.js has a built-in module called HTTP, which allows Node.js to transfer data over the http. To include the HTTP module, use the require() function.

 var http = require('http');  
  

Node.js as a Web Server

The HTTP module can create an HTTP server that listens to server ports and gives a response back to the client. we used createServer() method to create an HTTP server.

 var http = require('http');  
   
 //create a server object:  
 http.createServer(function (req, res) {  
  res.write('Hello World!'); //write a response to the client  
  res.end(); //end the response  
 }).listen(3000); //the server object listens on port 3000
