Switching between mobile webapp version using Ionic Framework and Desktop web app version?

Question

I own a web application that make use of Twitter Bootstrap 3.
This eases the design of the mobile version since it brings some responsive features.
However, I would like a really native-mobile aspect for the mobile version, but not a native for the Desktop one.
I searched..and I found this really promising framework: Ionic

It seems that this framework is really only focused on Mobile application and doesn't fit with any other kind of framework like Bootstrap (not mentioned in the documentation).

Therefore, my questions are:
What should be the strategy to keep a desktop version (not using Ionic but bootstrap 3) and a mobile version using Ionic? Making two distinct UI applications? One that would use Bootstrap and the other Ionic? What about duplications??

Answer 1

Have you considered creating your backend as an API?

This way you can focus on building any type of frontend (using Ionic or bootstrap or whatever requirements you have) without worrying what happens to the backend if changes are made.
