Learn nodejs simple way - First web application

We learned necessary concepts to write our first web application in nodejs. Lets dive in.

Steps

1. Create a file called "myserver.js". Import the required module(What module is required? http which is used to create a web server)

var http = require("http");

2. Create a server

var http = require('http'); // step1

//step2
http.createServer(function(request, response) {
    response.writeHead(200, {'Content-Type':'text/plain'}); // it tells that what kind of content will be delivered to the browser
    response.end('Welcome to Nodejs'); // Write the content and close the connection
}).listen(8082);
console.log('Web server running at http://localhost:8082/');

3. Run a program

node myserver.js

You could see the console log

Web server running at http://localhost:8082/

goto web browser and type http://localhost:8082 in the address bar. you will see the message "Welcome to Nodejs"
