Guys, I started working my initial state as a service idea, which should be a simple way to share state. I call it livestate (livestate.io) And I would love you to check it.
The code is open source, and very basic livestate.io · GitHub
@methyl I liked your solution for special purpose state very much, as it made possible to use type generation for TS, and custom methods. And it was actually your ideas which inspired me to go with the json-patch method
