Separate Apps or One General App?

[Paul]

Good morning,

I'm creating my site using AngularJS 1 which will have separate pages / apps.

Ex:   

example.com/myaccount

example.com/app1

example.com/app2

Each of these will be using their own set of ngRoutes (I plan to upgrade to UI Router soon, but that's a conversation for another time)

Each of these will be deriving from the same master html template (index.html for these purposes)

Should I create one siteapp.js and put it in index.html and derive my applications from that? Or should I create an individual app.js for each app?

ex:
    siteapp.js -> and use for basis for all apps

or

    app.js -> individual for each app?

Thanks!
