Is it possible to create a NW.js app (node), that don't have a window entry point?
I want to use NW.js, because I want to create windows, but not at the entry point. The app should work in the background, and open a window, at specific time.
Just set show:false in the manifest file, later on you can open new windows and close them.
As for window entry point you can always set a blank page or a single javascript file to be executed at start
