In
this post, I am going to explain how to develop simple web application using
node.js framework.
Step 1: Import required
modules. I am using http module to develop ‘Hello World’ application.
/*
Import http module */
var
http = require("http");
‘require’
directive is used to import the modules.
Step 2: Create the server.
http.createServer(function
(request, response) {
response.writeHead(200,
{'Content-Type': 'text/plain'});
response.end('Hello World\nWelcome to
node.js programming');
}).listen(8080);
As
you see above snippet,
a. Server instance
listens on port 8080
b. I am sending the
response code as 200
c. I am setting response
type as text/plain
d. Sending response
message to client
Complete
application looks like below.
/* Import http module */ var http = require("http"); /* Create the server, that listens on port 8080 */ http.createServer(function(request, response) { response.writeHead(200, { 'Content-Type' : 'text/plain' }); response.end('Hello World\nWelcome to node.js programming'); }).listen(8080);
Run
the application by executing the statement ‘node HelloWorld.js’.
Hit
the url ‘http://localhost:8080/’, you can able to see below screen.
