ReactPHP vs Node.js

index.js

var http = require('http');

var data = {
  'code': 'ok',
  'error': false,
  'payload': 'Hello World'
};

var app = function (req, res) {
  res.writeHead(200, {

};

var server = http.createServer(app);

server.listen(1337, function() {
  console.log("Server running at http://127.0.0.1:1337");
