a websocket server for NodeJS that creates growl notifications with the help of growlnotify

growlSocketServer.js

var port = 8000;

var WebSocketServer = require('websocket').server;
var http = require('http');
var exec = require('child_process').exec
var child;

function createGrowlNotification(cmd){
    
            child = exec('growlnotify -m "'+cmd.body+'" -t "'+cmd.title+'" --image "'+cmd.icon+'"',
                function (error, stdout, stderr) {
            });
}


// the main server
var server = http.createServer(function(request, response) {
    console.log((new Date()) + " Received request for " + request.url);
    response.writeHead(404);
    response.end();
});
server.listen(port, function() {
    console.log((new Date()) + " Server is listening on port "+port);
});

wsServer = new WebSocketServer({
    httpServer: server,
    autoAcceptConnections: true
});

wsServer.on('connect', function(connection) {
    console.log((new Date()) + " Connection accepted.");
    connection.on('message', function(message) {
        if (message.type === 'utf8') {
            console.log("Received Message: " + message.utf8Data);
            createGrowlNotification(JSON.parse(message.utf8Data))
            connection.sendUTF("growlnotify cmd executed");
        }
        else if (message.type === 'binary') {
            console.log("Received Binary Message of " + message.binaryData.length + " bytes");
            connection.sendBytes(message.binaryData);
        }
    });
    connection.on('close', function(connection) {
        console.log((new Date()) + " Peer " + connection.remoteAddress + " disconnected.");
