How to make Node Webkit work with express generator - node.js

Question

im trying to make an App with Node and Express using express generator and packing everything with node-webkit. express generator creates an extremely basic app , but it works running npm start on localhost:30000.
the manifest
{
"name": "app",
"version": "0.0.0",
"private": true,
"node-main": "./app.js",
"main": "http://localhost:8080",
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"body-parser": "~1.15.1",
"bower": "^1.7.9",
"cookie-parser": "~1.4.3",
"debug": "~2.2.0",
"express": "~4.13.4",
"morgan": "~1.7.0",
"pug": "^2.0.0-beta4",
"serve-favicon": "~2.3.0"
}
}
the folder structure
When i run the app with nwjs the window displays that the page can not be loaded, but the console doesn't show any error. I tried changing
"main": "http://localhost:8080" to "main": "http://localhost:3000"
which is how the app runs usually, but it didnt work either.
is this possible?
what am i missing?
thanks in advance

This can be a bit late, but anyway.
Here is the source: https://github.com/nwjs/nw.js/wiki/NW.js-use-express-and-similar-web-frameworks
node-main should have path to file, which sets up the server. In this case I assume it is located in bin directory and is named www. Therefore, the package.json should be like:
{
...
"node-main": "./bin/www",
"main": "http://localhost:3000",
...
}
Also check the port number if it is 3000 or something else.
