Hyperview is a very interesting mobile-oriented hypermedia system created by Adam Stepinski.
He talks about is in the third part of our book, hypermedia systems:
https://hypermedia.systems/part/hyperview/
I have said before that I regard his work as much more innovative than htmx in that he developed an entire hypermedia client and format for his system.
I'm curious about the limitations that prevent these apps from writing / caching local data. It doesn't seem like the paradigm would have to change entirely to support that.
There aren't any, with hyperview you actually own the hypermedia client as well as the server and you can write and cache local data in the form of custom extensions you make to it.
I think that needs better documentation though.
So, basically it's like every other non-native development environment for mobile: basically useless when you want to use any feature of the phone.
These things always implement the easiest bit of mobile development (the UI) and then make everything else harder, so it's useless for anything non-trivial.
i don't know if being that pessimistic is warranted i'd need adam to comment
