ZIO / FS2 / etc. integration examples about laminar HOT 5 OPEN

Self-aggrandized snake-oil coming up, sorry 😁

If you want to take this idea to the extreme: the main motivation for Calico is to answer the question, what if we built Laminar (or something Laminar-like, anyway) from the ground up with effects?

(It is effect-agnostic, so it can work with effect types other than Cats Effect IO.)

@valentin-panalyt Laminar only uses Airstream as a reactive layer. The underlying DOM operations work on low level observable-agnostic callbacks.

So, yes, in principle you can make a similar library with IO and ZIO instead of Airstream. And if you actually want Laminar-like observable API, you might want to use a streaming library, not an effect tracking library. So, more like FS2 / ZIO streams I guess. Either way, you will have to deal with various kinds of friction like FRP glitches because those libraries are designed for use in concurrent backend systems, and make different design decisions with different tradeoffs.

You might be interested to see how Tyrian and Calico are made, they both are FP-centric designs.

(Random comment: this will work with ZIO 2.x. You need to adapt the Unsafe shenanigans if you still use ZIO 1.x.)

Question just out of interes: would it theoretically be possible to rewrite Laminar using ZIO or cats-effect - or is that not possible due to things like "No FRP Glitches" or other aspects in how the effect systems differ?
