View source for Node.js: simple web server

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 from the command line:

 % 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');
