So what exactly are you asking for here? A list of PWA api's that must be used all the time in every single PWA app? What's the benefit of that? Which application development API has such an asinine requirement in the first place?
> Because of this you will always have people scream "Apple is killing PWAs" because they don't support a yet another random API.
I like the "yet another random API" phrase. It creates the impression that PWA APIs are being generated fast and furious, and apple is trying very hard to keep up with all these "random" new APIs.
Yet, the reality is that apple has for a long time deliberately crippled PWAs on their platform by not supporting just 4, crucial, old and fundamental APIs. I will list these for you:
- Background Sync
- Web Push
- Before Install Prompt and Installation Banner
- Background audio for PWAs
They do not have to implement any "yet another random API". Just those four. Everything else is a bonus, considering this is Apple's Safari (the new IE) we are talking about.
Imagine going 2000 years back with a book and showing it to some caveman. To you they are words, with meaning and purpose. To him, they're just random gibberish scrawled on some leafy stuff. He might even nibble on one of the pages and declare "it doesn't even taste good, what can be its use?"
