Node js + express is displaying great on localhost. My issue is, is that after I display static page which is doing it's job, my app.js script is not firing from the outside world. But when running locally it works like it is suppose to.

    //send html page to user
    app.use(express.static(__dirname + '/node_modules'));
    app.use(express.static('public'));
    app.get('/', function(req, res, next) {
      res.sendFile(__dirname + '/index.html'); //send the file


    });
 //My app 
 // everything below this line does not work

I followed the direction from express but still app.js is not firing from the outside world. Again it hits great on local. Any help that would be greatly appreciated!
