Xstate: Redux

[romseguy]

Cool project! In the context of Redux, I suppose it'd enhance reducers somehow, would you like to share with us your implementation of the counter example for instance?

[davidkpiano]

Thanks, @romseguy! I'm going to put up a clear example pretty soon, actually. Check back in 5 minutes!

[davidkpiano]

Here is a non-trivial example (more complicated than a simple counter) with React and Redux: https://github.com/davidkpiano/estado/tree/master/examples/vending

Let me know if you find that helpful! :smile:

[romseguy]

More than helpful actually, it's like reducers on steroids! On the top of that, who's not familiar with state machines? I'll be diving in the library code, and see if I can contribute somehow. A quick thought for now would be to propose an alternative to the DSL like using nested objects, but you probably already thought about that.

[davidkpiano]

Hey, good suggestion! You actually can pass in JSON objects written in SCION (a JSON implementation of SCXML). The only problem with that is that it's extremely tedious, haha.

What I really want to get moving on is meaningful error messages, such as when the developer forgot to define a state or a transition is missing.

is this example spoken of above not available now?

[davidkpiano]

@zz-james Not yet, as the above was based on an earlier version of the library. However, look 🔜 for a Medium article on how to incorporate it in existing projects, and I'd love to take suggestions for examples.

Hi David, I was looking around for either the outdated example linked above, or a medium article w/ an updated xtstate/redux example but was unsuccessful. Would you be able to make the old example available? I might be able to see how that works to fit it to my use case (with Angular and ngrx).

@jmcmichael Examples are coming 🔜 this week! I'm working on releasing V2.0 (largely the same API as 1.0 but with tiny breaking changes for better type safety/predictability) and want to base the examples on that.
