AN EXAMPLE: WEBSERVER

This simple web server written in Node responds with "Hello World" for every request.

var http = require('http');

http.createServer(function (req, res) {

  res.writeHead(200, {'Content-Type': 'text/plain'});

  res.end('Hello World\n');

}).listen(1337, "127.0.0.1");

console.log('Server running at http://127.0.0.1:1337/');

To run the server, put the code into a file example.js and execute it with the node program:

% node example.js

Server running at http://127.0.0.1:1337/

Here is an example of a simple TCP server which listens on port 1337 and echoes whatever you send it:

var net = require('net');



var server = net.createServer(function (socket) {

  socket.write("Echo server\r\n");

  socket.pipe(socket);

});



server.listen(1337, "127.0.0.1");
