Clojurians Log v2

I like it! It actually helped to clear my mind on some things (storing the state in the immutable render tree e.g.)

I would show the equivalence between class components and stateful function components, seems like a lot of CLJS people are not up to date with hooks.

And finally the useMutableSource API which allows React to sync with an external mutable source which avoids tearing. I suspect Redux E.g. will adopt that.

i think that the key understand tho is that all useMutableSource does is help React realize that the state has drifted and restart rendering

so it’s not for free

In newer versions they will improve perf a little bit (lanes)

I’m basing this on browsing PRs

yeah hopefully. I haven’t grokked the new “lanes” concept yet

It’s not for free - but global state is unavoidable in most applications. For many use cases performance is irrelevant because the state changes “rarely”, E.g. fetching from an API

yep data fetching, navigation, etc. are major reasons for needing external state

I decided to throw in the towel with trying to read the tea leaves of the React team. I think having an API of a custom hook can let me build for today and be able to be nimble tomorrow.

yep yep! I just hide all my stuff behind a custom hook and wait to see what works best :D

Recoil E.g. has an interesting idea. The state identifiers are global but state is stored in the React tree.

I can definitely make reseda work like that eventually.

yeah, I’m interested to see how successful it is

I had a similar idea but I was wary of the performance of that much indirection

also the API is really wonky if you want to use it with things outside of React

I’m still not sure if just getting references to setState hooks and calling them in a batch makes sense or not.

I mean, for react stable that’s all you can do, right?

it gets real weird because you need to ensure that you don’t call setState on a component that’s been unmounted

and other corner cases. it’s icky

Yeah, I guess - looking at redux and others you just have to useLayoutEffect or something along those lines. But to force a rerender it’s either a HOC or that...
