[Docs Rewrite] Meta-Issue: Rewrite Examples

This is a tracking issue to cover all tasks related to rewriting our existing example projects.

Tasks

• Decide which examples can be removed (like todos vs todomvc vs todos-flow)
• Rewrite remaining examples with Redux Toolkit and React-Redux hooks

@giacomocerquone I think it’s worth reviewing all the examples, deciding what the original intended purpose was, and then deciding what the overlap is and what should be removed.

I do actually think the tree-view example is useful - this was a big question early on in the life of Redux about “do I just connect the top component, or multiple components?”, and it shows components extracting items from the store based on ID as well as recursive rendering. Someone over in Reactiflux was actually trying to port that to hooks as a learning exercise yesterday, which is what prompted me to file this issue.

todomvc is a slightly larger version of todos. This was more relevant when the TodoMVC project was being widely used as a comparison between varying UI frameworks, and it at least looks nicer than the barebones todos project, but tbh it can probably be removed.

Haven’t looked at async lately, but yes, it can probably be removed.

I would honestly just go replace counter with the contents of our Redux+JS template for Create-React-App:

https://github.com/reduxjs/cra-template-redux

Flow is dead, effectively. I would delete that one.

On the other hand, I would consider having a counter-ts example that copy-pastes the Redux+TS template for CRA. We ought to at have least one TS-based example in there somewhere.

The other thing to consider is that I’ve built out a larger real-world-ish app as the example for the “Essentials” tutorial, here:

https://github.com/reduxjs/redux-essentials-example-app

and this TodoMVC-based app for the “Fundamentals” tutorial:

https://github.com/reduxjs/redux-fundamentals-example-app

We’re going to keep those repos because I want them to be independently cloneable so people can try out the projects themselves, but we should probably either link to them on the “Examples” docs page, or copy-paste the final versions of the code into projects in the /examples folder.

@zpwebbear : No particular timeline for this. It’s just something that crossed my mind yesterday as a thing that needs to be done at some point.

This is made redundant by #3565. I would still like to move the examples out of this repo, as they add a ton of weight to the test process and a lot of noise to the git history.
