I’m newer to the community, but it seems like these things are doable in Wappler. I haven’t found anything I was not able to tie in to Wappler, even if just by doing a little hand coding here and there.
I think you’ll run into a number of confusing or glitchy things, like you’d expect writing your own PWA in any dev environment. I think if you’re under a tight feature scope or schedule, this could be a steep project for your first in Wappler.
If you decide to give it a try, I recommend figuring out the essentials on paper and then get those working in Wappler. For instance, I’d want to be sure I could live with the development cycle depending on your PWA requirements. The QR code situation would be the other element I’d get working first off…
Good luck & let us know where you end up!
