What features should all flask apps have?

[u/Status-Fold-6860]

I've been programming for about a year and a half now and built a small flask app to manage my music business. Basically a management application with some API integration and sqlalchemy. The app now works fine and is stable, but I'm wondering if there are any features/functions/etc. that all flask apps should have implemented, that don't seem obvious to a beginner like me. Cybersecurity and complex algorhithms still go a bit beyond my understanding, but I wanna make my app as secure, stable and reliable as possible.

How are you serving it? Is it using app.run() or is it being served by a "real" server?

I'm using app.run() on a remote computer with ubuntu via ssh
