Using Concurrent React features with Redux/RTKQ

[einarq]

Has anybody been able to leverage any concurrent react features to create a more performant UI?
I know that the redux updates themselves cannot be interruptable until concurrent stores are a thing, but perhaps it is still possible to improve certain performance in some cases using these concurrent react?

Tried asking ChatGPT a bit, and it seems to think that this should work. But I'm an old head so I dont really trust AI that much, and this doesn't match what I have experienced when I have tried.

Disclaimer: I do find the whole concept of actions and transitions to be slightly confusing, so I might be "holding it wrong" whenever I try to do it...

Apologies for the tag, but this was too interesting to not raise a bit 🙂

I assume you have watched this talk?

The big takeaway for me was:

• yes, useSyncExternalStore makes it hard to optimize rendering with concurrent features (if not impossible)
• concurrent stores has the potential to make redux (and other external stores) the big performance winner in the React space (for now...)

Any thoughts?

Yep!

In case you haven't seen it, I've been helping Jordan Eldridge prototype the new concurrent stores API. I tried it out in React-Redux to do an initial test and fleshed out some of the use cases, and filed some PRs to the polyfill to add equality support. Jordan just filed the initial actual draft PR to React itself:

• [DRAFT] Initial React "concurrent stores" compat prototype react-redux#2263
• Add useStoreSelectorWithEquality wrapper thejustinwalsh/react-concurrent-store#22
• [RFC] useStore/createStore APIs captbaritone/react#1

I have definitely seen that, very cool. I even kind of convinced you that it was ok to deprecate “connect” (I think) 😄congrats this is actually sorta your fault for prompting that discussion :) https://bsky.app/profile/acemarke.dev/post/3m6avdjfog32n
