Seeking skeleton web-addin (Outlook / AngularJS / asynch dialog)

I have been trying for many months to develop :

•  an Outlook web add-in
•  using AngularJs.
• when the user clicks a button on the ribbon bar (not compose or read frame)
•  an asynch dialog is launched, using displayDialogAsync()

I have found many demos which have on or more of those requirements, but not which fits them all 😞

Really, I don't care too much about what I consider to be "just the framework" (no offence intended), I just want to drop my AngaulrJs app into that asynch dialog.

Does anyone know where I can find a demo which ticks all of those boxes, which I can eviscerate and drop my won code into?
