var http = require('http'); //create a server object http.createServer( function(req, res){ res.writeHead(200,{'Content-Type':'text/html'}); res.write('Hello World'); //write the response to the client res.end(); //end the response } ).listen(8080); // the server object listen on port 8080
http.createServer().listen(8080)
when you run that command on the node shell, it will create a server on local host and print hello world.
