How to create a server with node.js?
Node.js makes it easy to create a simple web server that processes incoming requests asynchronously.
The following example is a simple Node.js web server contained in server.js file.
var http = require('http'); // 1 - Import Node.js core module
var server = http.createServer(function (req, res) { // 2 - creating server
//handle incomming requests here..
});
server.listen(5000); //3 - listen for any incoming requests
console.log('Node.js web server at port 5000 is running..')
In the above example, we import the http module using require() function. The http module is a core module of Node.js, so no need to install it using NPM. The next step is to call createServer() method of http and specify callback function with request and response parameter. Finally, call listen() method of server object which was returned from createServer() method with port number, to start listening to incoming requests on port 5000. You can specify any unused port here.
Run the above web server by writing node server.js command in command prompt or terminal window
