Getting started with ionic and angular

I’m considering using Ionic in my next project. I’m already well-versed in Angular. My question is does it make sense to build my app using Angular and integrate ionic later or would I be shooting myself in the foot? If it uses webviews I would imagine it wouldn’t be too bad to add it later.

I was probably gonna use something like Angular Material for the web app, but perhaps it makes sense to integrate ionic as the component library for web app as well or is it only for mobile apps? From what I can see though it seems to be mobile app focused component-wise unless I’m missing something. Thoughts?
