Minimal REST nodejs server

rest.js

var http = require('http');
var port = 8080;

var server = http.createServer(function(request, response) {
  console.log('Requested URI:', request.url);
  response.writeHead(200, {'Content-Type': 'application/json'});
  response.write(JSON.stringify({a: 1, b: 2}), 'utf-8');
  response.end();
});
server.listen(parseInt(port, 10));

console.log('Starting server on port ' + port + '. To stop, press Ctrl + c');
