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');
