Ionic components into angular project


I am working on an ionic app for almost 1 year and half.
It is finished but now I would like to create my site with angular 5 and add some features of my app.
I don’t want to bring all the cordova stuff. I just would like to do a simple pwa with angular.
However I like some features of ionic like the slides, items and button

I tried to import Ionic with the IonicModule. However I get warings and my routing is not working anymore. Is there a simple way to import ionic modules in angular project?
