After witnessing "peak RSC frustration Twitter week", I sat down on the weekend and tried to write down my take on this - as a blog post.
More balanced.
No unexplained frustration in 280 characters.

Library maintainers!

This could be interesting for your documentation.
* it transpiles TypeScript code examples to JavaScript
* it typechecks your TypeScript code examples
* it allows you to include Docblocks from your sourcecode

This one is for library authors: frustrated how TS versions handle your package slightly differently, but don't want to ship a full copy of your types with TypesVersions? Now you can adjust your types depending on the TS Version!

I cannot stress how much I want to recommend everyone using Redux to go through our Style Guide from time to time. Many tutorials, blog posts and even books out there show styles of building Redux logic we explicitly recommend against.

The exact opposite of this whole thread.

> The React canary channel is stable for frameworks like Next.js to adopt
Be honest: This point is such a fig leaf.
The only framework that can get the insights to do so right now is Next.js, because you have the React team next door and there's no doc.

So apparently `Promise.race` can cause a memory leak because it never stops waiting for the failed promises. I would have assumed that something like that is handled by the JS engine.
Of course we use that in RTKs `listenerMiddleware` - time to fiddle around...

Hi, I'm a Redux maintainer.
Those are two technologies that do different things and are often used together - about 40% of React applications choose Redux as well.
You will *never* be in a situation to choose between them.

Honestly, she makes a pretty good point. If there are people at the same company who are significantly senior to her and still earn the same amount of money, there's no incentive to stay there other than "enjoying the job" - which she clearly didn't. So good for her to get out.

Someone is gonna find a bug that can only be reproduced with Node 22 stable, React 19 beta, TS 5.5 beta and Apollo Client 3.10, all which released in the last 24 hours or so.

I'm a bit sad that this was not communicated before.
Fetch being patched is not a small thing - and from reading the code, this might cause problems with some polyfills - at least from my experience from creating RTK Query.
I'm sorry... but, what?
Is React now fucking with the global fetch() object?
Please say it ain't so

I very much agree to this. TypeScript enables us library authors to do amazing things - but the ecosystem for lib devs is not there. Doing things right is often undocumented and a pain. Yet, it's worth is.

No, sometimes I want to convey intent that the Compiler cannot meaningfully infer, and then writing the type explicitly is very valuable - for the author, the reader, and the codebase.
After 6 years of TypeScript, JavaScript is just random mush to me that makes me anxious.

I wrote a blog article why you should not use the "discriminating union"

reducers.
I like the pattern, really. Just not in this case.
It's a lie to the compiler (and yourself).

And I have a working demo of RTK Query results suspensefully streaming from React SSR to the Browser, made possible by the hooks I patched into the React sources.
Beware, everything about this is very experimental 😅

Has to be a bubble thing - in my bubble it's the other way round.
But there also seems to be a bit of a disconnect here... IMHO, TypeScript mostly*is* about inference, not about types.
Those should only be written where necessary.
The less explicit types, the better.

"Endorsment"? Really? That's your boost, and anyone should be affected by that?
It's called analyzing the use case and using a fitting tool for the use case.
I hope nobody ever does anything just because Facebook does it. Most of us have vastly different problems to solve.

One of our users came up with a way around this:
Put the secret token into a prop (which will leak into the client bundle), but encrypt it - and have the encryption key available only in RSC & SSR using non-exposed ENV variables.
I made a package for it:
😣 he's right
Client components can't read cookies during ssr—credentials: include does not work in ssr fetch call, nor can cookies be read in middleware for that call
I'm about ready to give up on app dir for app development. Maybe Tanstack or Remix will ship something usable

The performance increased mentioned in the blog article was gained by using plain C. What has swift to do with that?
And how exactly was swift boosted? Is there any tooling available for swift developers now that wasn't before? Did it get better in any way?

I just took a stab at implementing `use` support for RTK Query and just from looking at the code changes, this is mostly moving code around - almost writing no new code. It is probably the cleanest attempt at suspense support we've made so far.

Very happy to see that this is fixed in React 19 - finally useSyncExternalStore will batch together with other state updates and not cause double renders. (Think a Redux dispatch and a setState call at the same time.)

Go by the React Docs Beta. Don't touch anything that shows class components or switch..case reducers. You want hooks. Always check library homepage & docs before starting external tutorials.

Every other framework will be behind, because for a lot of the features the only "documentation" is the Next.js implementation.
(Looking at e.g. the timing specifics behind useServerInsertedHTML - there's no guarantee or doc, the only safe thing to do is doing what Next does.)

@thekitze
Yup. But then there's also this part in the Redux docs - and there's a direction that Redux is pushing (no switching reducers, no type constants, no hand-written action creators, hooks where possible). It's a bit like bashing on React for Class Components in 2019.

This is being taken care of. No more mob needed.
That PR is being rolled back in a major release, as agreed by the new maintainer in the PR, days ago.

It was a legit transfer according to Jesse, they have worked together before. I have a call with the new maintainer later today to try and sort some things out. Seems like some checks and balances are needed!

Those Redux jokes are getting about as old as the style of Redux you're joking about... could be a good idea to take another look at what modern Redux (with Redux Toolkit and Hooks) looks like ;)
Just saying, by now you're devaluing yourself more than you are devaluing Redux...

PSA:
If you've been using one of the experimental packages for Next.js App Router support with Apollo Client, urql or React Query, please update that dependency ASAP.
All three were vulnerable for an XSS attack, and all three packages just published a new version with a fix.

Did some docs work on RTK-Query earlier and came up with this neat little trick to refetch unauthorized queries on login & re-fetch queries with errors. This invalidation model really allows for a lot of nice patterns 🥳

If you're not using strict mode, you're probably closer to the feature set of TS 1.5 than the feature set of the language everyone else knows as modern TypeScript.
If you're not using strict: true in your tsconfig.json, you're not using TypeScript.

To be honest, the "Dan himself" argument gets very annoying at this point. Dan has created Redux and then maintained it for one year. Mark and Tim are now maintaining Redux for 6 years. Dan is an expert on how the React team wants you to use React, and they want you to not use

To become a billionaire just by working hard you would have to work for 40 years, 80 hours a week, never take a day off at $6000/hour (after taxes).
There is no "earned" or "hard" way one hour of your life is worth more than a month of another person's life.
