Why node.js server in Visual Studio for Azure is created differently? -

i ran strange problem in azure project seems related how server created. project created using basic azure node.js express 4 application template in visual studio 2013 ultimate. after struggle, project runs fine locally, until hit browser's refresh button never comes back.

the project created in webstorm , didn't have problem. figured, difference between them minimal: in webstorm, used:

var server = http.createserver(app); server.listen(process.env.port, process.env.ip); 

but in visual studio, used (created template in www file):

app.set('port', process.env.port || 3000); var server = app.listen(app.get('port'), function() {     console.log('express server listening on port ' + server.address().port); }); 

when replace webstorm version, seems work fine again. can explain why?

by way, in app, i'm not using node views. instead, i'm using:

app.set("view options", { layout: false }); app.all('*', function (req, res, next) {     res.sendfile(__dirname + "/public/index.html"); // send index.html other files support html5mode }); 

could related problem?
