Introduction

Node.js has a built-in HTTP module that transforms your computer into a live web server. The server listens on a specific port and sends text or HTML data back whenever a user tries to load the web page.

Example

1/* this creates a server */
2var http = require('http');
3
4http.createServer(function (req, res) {
5  res.write('Welcome to my server!');
6  res.end();
7}).listen(8080);

Key Points

Import the module using `require('http')`.
The `createServer()` method builds the server.
The `listen()` method chooses the network port.
The server responds to incoming client requests.
