Thanks for the feedback. I've pasted it into our "Docs Rewrite: Overview" issue for reference [0].

Responding a bit further:

There's not much we can do about folks going back and forth between Redux and various non-Redux-y things. That's outside of our scope and ability to help with.

Teaching-wise, there's several reasons why the docs are structured the way they are right now:

- Redux itself is an independent library that is not tied to React in any way (and is used with other frameworks / UI layers as well). Our docs do mostly assume that you're using React, but the tutorials start out trying to show how you'd use Redux without any UI layer, to teach the basic concepts.

- React-Redux has been a separate library from Redux itself since it hit 1.0. While we do teach the basics of how to use React-Redux in the Redux core docs, it has its own separate repo and separate docs site. Similarly, RTK was designed as an addon layer around the Redux core, so it also has a separate repo and separate docs site, and its docs assume that you understand the basics of Redux already.

- That said, yes, the vast majority of Redux usage _is_ with React, and we are encouraging folks to use RTK as the default way to write Redux logic. So, it's very reasonable to have a docs page that shows how to jump right into using both of them as fast as possible. This is something I've already said I want to add to the docs, as a "Quick Start" page [1].

In terms of teaching flow and learning, there's various ways to approach explaining things. Dan Abramov wrote the original Redux docs content and structure, and his teaching style is very much "bottom-up, from first principles". You can see that style in pages like the current "Middleware" tutorial page [2], and his Redux videos on Egghead [3]. That approach works great for some people, but other folks just want to be shown _how_ to do something first, and learn the "why" later. It's hard to serve both groups at the same time.

One issue with teaching RTK first is that while Redux requires / expects that you use immutability correctly, RTK's use of Immer does hide the fact that immutable updates are happening in the background. It would be easy for someone who learns Redux via RTK to assume that writing mutating logic _is_ the right way to write reducers, not realize that it only works right due to the "magic" inside RTK's APIs, and then go write reducers in another project without RTK that are completely buggy as a result. I haven't yet entirely figured out how to handle that aspect, other than plastering warning notes all over the docs. That's one reason why I would prefer that folks understand the core principles first and how to do things by hand, and then switch to RTK to write the same code in simpler form.

As I said earlier, there's good reasons why we have separate libraries and separate docs sites. I can hypothetically imagine pulling things together into a combined docs site, similar to how NgRx does it [4]. But, I'm not sure how technically feasible it would be. It might require restructuring everything into a mono-repo, and I don't think I want to have to figure out how to migrate everything at this point.

All that said, yes, part of the goals for this Redux core docs rewrite is to provide a much more obvious learning path.

Finally, no, I don't think RTK is "killing the ecosystem around Redux", as the ecosystem is much broader than what RTK includes. RTK does obsolete a lot of similar libraries, but there's many other pieces out there for other use cases.
