redux-eggs VS redux-templates

We have docs on code splitting reducers and other Redux logic here:

- https://redux.js.org/usage/code-splitting

There have been some different community packages for helping with that process, but some of them seem to have become outdated (only worked with React-Redux v5, etc). I did see a new one at https://github.com/fostyfost/redux-eggs that seemed like it had potential, but I haven't had a chance to try any of them myself.

I also once saw someone play around with the idea of using React's still-not-technically-final Suspense support to help ensure that a lazy-loaded component that relies on a code-split reducer doesn't actually get rendered until that reducer's state is available. Don't have the link handy atm, but if someone wants it ping me and I can go figure out where that was described.

Also, the new RTK "listener" middleware was specifically designed to replace almost all saga usages, and you can dynamically add more listeners at runtime via dispatch an `addListener()` action:

- https://redux-toolkit.js.org/api/createListenerMiddleware

- https://blog.isquaredsoftware.com/2022/05/presentations-evol...

I did see a recent package called https://github.com/fostyfost/redux-eggs which looked like it did the same kind of "add and remove modular chunks of Redux code" use case, but I haven't had time to try it out.

Yeah, _please_ don't use `typesafe-actions` :)

It may have had some value before RTK came out, but a lot of the opinions and approaches shown in its docs lead you to write _wayyyy_ too much code. For example, we specifically recommend _against_ writing TS unions for action object types [0].

RTK completely obsoletes `typesafe-actions`, and the TS usage patterns that we teach today should result in a pretty minimal set of types that you need to write in your own code.

For a small example see the RTK+TS template for Create-React-App [1]. If you want to see what a real app codebase can look like, the client app for my day job at Replay.io is OSS [2]. It's admittedly a somewhat messy codebase due to its long evolution and legacy (started as the FF DevTools codebase, copy-pasted, and we've been slowly migrating to RTK+TS and modernizing it), but files like [3] show how I would write a real slice reducer with RTK+TS.

The recommended way to initialize a new app with React and Redux is by using the official Redux+JS template or Redux+TS template.

I learned the basics of react initially, and then when I started using typescript + react, I did so using the create-react-app typescript redux template. I found that having a template to build from was extremely helpful. I'm sure there are other good templates out there if you didn't want to worry about redux (I think it's good, but it's got it's own mental overhead), but being able to refer to the template implementation was extremely helpful, since the typings of some react things can be highly weird.

Please see the official Redux+TS template for CRA, which shows the correct "modern Redux" patterns in action, as well as the "Modern Redux with RTK" tutorial page and our recommended TS usage patterns.

btw, note that we have an official Redux+TS template for CRA that comes with RTK and React-Redux already configured.

Now the first two questions have been answered. Moving on to the next one, state management. I decided to use redux. Came across this amazing toolkit and this beautiful and friendly template template from the official reduxjs repository.
