FWIW, my estimates show that Redux is still used by 35-40% of React apps [0]. That's definitely less than it was a couple years ago, but still the largest usage of any React-related state lib by far. (It's also worth noting that

For the record: I maintain Redux, and it's never been an actual recommendation from the React team. In fact, Dan has publicly stated that "the only state management tool we recommend is React itself". Redux is certainly the

I wouldn't say that at all. The React Core team was 100% Meta up until earlier this year, when Seb Markbage switched to Vercel (and I believe Vercel is now also funding an additional full-time dev to contribute more React SSR / Se

Yeah, sagas can be useful - not saying they aren't. But on the other hand, I've seen plenty of codebases and talked to lots of Redux users where sagas turned into an impenetrable spaghetti mess of actions and events going everywhe

Hmm. Lenz ( @phryneas in most places) could speak more to some of this, but I don't think RTKQ really supports the idea of "canceling" a fetch in general. Can you give some specifics about what that means in your case? As fo

Yes, Redux Toolkit is still Redux. There's still a single store, dispatching "action" objects that describe "what happened in the app", and pure "reducer" functions that calculate new state immutably in re

Hi, I'm a Redux maintainer. A few thoughts: First note is that while both of Redux's original creators (Dan Abramov and Andrew Clark) later got hired to work on the React team, Redux has always been an independent project, and is

Very nice bit of archeology! Back in 2017, about a year after I took over as Redux maintainer, I wrote up a post exploring some of how Redux works, its design constraints, and the intended goals and influences: - https://blog.isq

Please note that "modern Redux" code is very different than what most older tutorials show. We've introduced newer APIs like Redux Toolkit, which is a set of utilities that simplify the most common Redux tasks, and the React-

I'm legitimately curious. Can you point to a single actual source to cite "the React team made the change to hooks because of JS engine performance"? (and when you say "performance", you _are_ talking about literal

I think you're really misunderstanding how React works here. There's no "thrashing" involved, in the sense of "make DOM update A, then need to make B that reads layout or does reflows right after". - React does

You're very much misreading what I said. It's not about "optimization" in the sense of "how fast can the v8 interpreter execute lookups on the class instance" or anything like that. It's about "when t

Yep. The article has some good points overall, but Context was definitely never intended as a replacement for Redux. Redux and Context are different tools that solve different problems, with some small overlap. Honestly, this is a point of

FWIW, Redux and Context are different tools that solve different problems, with some overlap. Context is a Dependency Injection tool for a single value, used to avoid prop drilling. Redux is a tool for predictable global state management, w

I'm afraid I'll have to disagree with all of the above, especially the part about building libs. Per the OP's article and my slides, there _are_ many aspects of maintaining a lib that are unique to TS above and beyond a plain

I'm very curious, which "Redux code" are you referring to here? I don't think the `redux` core lib ever shipped any Flow types itself. Looking at the FlowTyped repo, I see community typedefs at https://github
