Nodejs Chatroom Free Plugin Available

How do you create a simple chat application?

In this tutorial, I’m going to help you create your own chat application. You can  integrate  into any project! This tutorial help to the complete development of a chat application.

We’re going to be creating a Node.js app, Please make sure you have it installed.

Let’s start :

• create a folder
• cd into that directory in your terminal (command line)
• run npm init . This will create a new package.json file. (it will ask you name/version, etc.)

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.

Use the 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(8080); //the server object listens on port 8080
