Hello dear community 
I am currently building a small web application.
The goal at a later date is to “convert” the web application into a progressive web app. For example, there is currently the option for users to upload a picture to their profile - later I would like to implement the camera function to make it easier for the user.
It’s still a long way off - but I keep asking myself whether I’ll have to adapt my entire framework later - or whether I can only add/adapt individual functions.
What would you recommend me - here I have to say that I am not familiar with PWA and I still have a long learning process. Can it still be a good way to build the application for a mobile version - and implement the PWA functions later - or is that a completely wrong approach?
