Hmmm if you don't have to do any server at all and you already know Angular then that might fit. More about the workflow of creating an app and splitting up the work into an API and a JS heavy front end where good old HTML might work as well

I would agree there - the last app I build I used vanilla js and bootstrap with a flask Python backend but for nostr I thought angular fit well as it’s purely a frontend application (from the app building perspective) obviously the relays serve as the backend which is nice
