Need advice

Hi everyone, I’m freshman in vaadin and everything which has common with frontend(I’m only backend developer, I’m even don’t know basics of JS)
I’m lookin to chose as client part Vaadin and want to use it only client part, and want speak with backend api with retrofit
So my question is do it sounds like stupid idea or that could have point ?

If you want to use Vaadin Flow - all the logic runs on the server. You don’t need to expose any rest interfaces and therefore probably don’t even need retrofit. If you wanna call external / internal other services feel free to use to tho to consume the results in your views
