@konsoletyper As for state, yes, state is stored server-side, there is a companion project
https://github.com/kwebio/shoebox which is one implementation of observable server-side state. The whole thing works by binding DOM elements to state. It means that, for example, if another use modifies something - this would be reflected immediately in the DOMs of any user looking at a view of that data. And you get that more-or-less for free
