var WebSocketServer = require('ws').Server	// include Web Socket server

// you need a  body parser:

// this runs after the server successfully starts:
function serverStart() {
	var port = server.address().port;
	console.log('Server listening on port '+ port);

// this is the POST handler:
app.all('/*', function (request, response) {
	console.log('Got a ' + request.method + ' request');
	// the parameters of a GET request are passed in
	// request.body. Pass that to formatResponse()
	// for formatting:
	console.log(request.headers);
	if (request.method == 'GET') {
		console.log(request.query);
	} else {
		console.log(request.body);
	}

	// send the response:
	response.send('OK');
	response.end();
});

// start the server:
var server = app.listen(8080, serverStart);

// create a WebSocket server and attach it to the server
var wss = new WebSocketServer({server: server});

	// new connection, add message listener
