I am building project with Ionic 5.
Yes you can. I’m doing this myself. It is done though capacitor
I can think of two ways to interpret this question, to which I would have two different answers:
A: can capacitor also bridge to cordova plugins? a qualified “yes” here, as @Vigors says. some cordova plugins are compatible, but not all.
B: can I build with both cordova and capacitor? I can’t think of a benefit to trying to do this.
