Hi, I'm hoping you lovely people can help me out with my approach to updating state. I've been using data classes to represent State and the nested values on it, but I'm finding this cumbersome for some use cases, especially with nested data:

state.copy(levelOne = levelOne.copy(levelTwo = levelTwo.copy( value = 0 )))

which may not seem too bad here, but does get quiet verbose when I'm trying to update several values at two different 'paths'. Additionally I need to get/set values dynamically (think lodash's set/get functionality) i.e.,

get<T>(state, "levelOne.levelTwo.value)

and

set(state, "levelOne.levelTwo.value", 1)

. I should note my state is being serialised/deserialised to/from Firestore as a Map. To accomplish the above, I'm converting my hierarchy of data classes to a map (with nested maps) using jackson, and then implementing the set/get functionality on those maps, before converting back to the original State data class hierachy. But this seems needlessly complex. For example, I have to convert everything in the specified update path to a mutable structure, transverse the maps, and do lots of casting along the way. But, the benefit is that nested access is straightforward and my reducers are simple:

reducer(state: State, action: FSA) {
   val payload = action.payload
   // I actually do this in my root reducer so i just mutate state directly here
   val fresh = state.copy()
   val oldValue = get<Int>("levelOne.levelTwo.value")
   set(fresh, "levelOne.levelTwo.value", 3 * oldValue)
   return fresh
}

I'm thinking one improvement I could do is implement something like immerjs where state is 'patched' in reducers and the patches are applied all at once before the root reducer finally returns the next state to minimise my converting to/from maps. The friction here stopping me from going to Maps altogether, is with data classes I get type safety when reading most values from state normally ...

val some = tate.levelOne.levelTwo.value

. Grateful for your thoughts/objections to the approaches above 🙏

Hello, Any chance to release JS artifacts compatible with new IR backend and Kotlin 1.4-M1?

@Buzz questions on what to work on in redux-kotlin thread

Is there a version of kotlin-redux compatible with Kotlin 1.4-M2?

ReduxKotlin v0.5.1 is available 🙂 • a thread-safe store • recommended way to create the store is now `createThreadSafeStore(reducer, state) • updated to Kotlin 1.3.72 • more info: • https://reduxkotlin.org/introduction/getting-started • https://reduxkotlin.org/introduction/threading

is redux-kotlin-thunk 0.4.0 compatible with redux-kotlin 0.5.1 or do we need to wait for new release?

Which platforms is threadsafe artifact published for?

@Patrick Jackson I tried using the redux kotlin presenter middleware, but unfortunately couldn't get it to work in my project because it has javascript which I saw was commented out in that project due to coroutine support at the time of its creation. I tried pulling the repo to see if I could update any of it, but running into a lot of problems. Wondering if there is any plan to update that project to support other platforms like js? Or maybe some guidance on trying to support js for it?

Hi all! I’ve written a reducer function like this:

val splashReducer: Reducer<SplashState> =  { state, action -> return state }

and when I call it on iOS I have a EXC_BAD_ACCESS (code=1, address=0x0) error If I write the function like this:

fun splashReducer(state: SplashState, action: Any) : SplashState { return state }

it works! Do you think it’s a problem with reduxkotlin or with kotlin-native? P.S. On kotlin-android it works with both

ReduxKotlin v0.5.2 is out! This is a release with all platform artifacts published to maven central. No new features or bugfixes. CI/CD is setup!!! Automatic publishing to maven central for releases and snapshots. This is going to be a big help. Happy 4th of July! 🇺🇸

is arm32 not avaiable? it gives me an error if I add that target.. does apple don’t want arm32 support anymore?

Hey! We are trying to implement a project with the https://github.com/reduxkotlin/presenter-middleware. Unfortunately it is not compatible with the current version (see https://github.com/reduxkotlin/presenter-middleware/issues/3). We tried to downgrade all the other redux-kotlin dependencies, but unfortunately it breaks somewhere else with a similar error. We even tried to checkout the repo and fix it by ourself, but we didn’t get it running. Now after some hours of troubleshooting, we don’t know what to do anymore. Could anyone please help us with either support the store as a interface in the middleware or how to build and run the project and the module locally? Thanks alot!

Any chance for Kotlin-1.4-M3 release?

Hi, I found

Kotlin Redux

a few days back and now Im starting to learn and study it. I understand the concepts very well but I just can't get how to model the

AppState

right. How exactly do you model the

AppState

? Examples I've seen so far only show a small application where the

AppState

is very simple. But how do you model an

AppState

in a Large Application with multiple screens? Do I make smaller "`AppState`" inside the "root"

AppState

like:

data class AppState(
    val loginAppState: LoginAppState,
    val signUpAppState: SignUpAppState
    val someOtherScreenAppState: OtherScreenAppState
    ....
)

data class LoginAppState(
    val usernamer: String,
    val password: String
    ....
)

It seems that 

Redux

 makes sense when screens share state between screens such as the Todo Application Example or its very simple when dealing with single screen application such as the Counter Application but how do you model the 

AppState

 when working with screens doesn't really have connected state such as an application with a 

LoginScreen

 and 

SignUpScreen

. Those two screens doesn't share any state. How to deal with these kinds of scenarios? I'd really appreciate any help. Thank you very much in advance

how do you trigger navigation in Redux? Is navigation also part of the AppState in Redux? If so does that mean I also have to have a reducer specifically for navigation?

Any help would be greatly appreciated

Yes. I wound up figuring it out, but there’s a lot of spots in this tutorial where it gets you nearly there without connecting the dots properly. Left me frustrated.

Any plan to update MovieSwiftUI-Kotlin’s Compose part?

Hey all, I have lots of actions going on when my mobile app launches, I was wondering if there's a way to Throttle the store subscription and reduce the number of re-render triggered

Hey all, I’ve added a logging middleware that logs the action and the next state to the end of my middleware chain. This logs the action right before it makes it to the reducer however because middlewares can modify an action I can’t guarantee that the action being logged was the original action that was dispatched.  My initial thoughts were to add a log middleware to the beginning of the middleware chain in addition to the end of the chain but I’m concerned about spamming logs since we dispatch so many actions.  Does anyone have any thoughts or feedback on this?

Does anyone have experience adding async features to the Store via coroutines? We have some calls to dispatch coming from a coroutine living in a fragment lifecycleScope, if the developer called dispatch and navigate to a different fragment, the dispatch call gets cut short. My thought was to offer a new dispatchAsync method using the application scope so it outlives the fragment scope, and then from the Store, for safety, the store calls back to the subscribers with a new launch to default back to the main thread, as most of the subscribers are assuming they are being called on Main.

@Patrick Jackson Any plans to update to latest Kotlin version?

I am creating a store val mystery = store( reducerFun, MySpace, rEnhancer( )) Fun reducerFun = { state: some Classic, action:RAction -> ......} When I run this, and check in the browser dev tools. There is an issue in Kotlin-redux.js line 30 closure$reducer(state,action.action) that mismatch type action.action is not a function. Looking through action.action is of type RAction which is not a function. Am I declaring things incorrectly?

@channel anyone interested in contributing to reduxkotlin? I haven't had time in past year to do much (switching jobs, moving across country). Would really like to get updated to kotlin 1.6, which should be straight forward

Is there any need to upgrade? It seems to work fine with 1.6.10 for me.

Are there any good examples of how I could make all of my redux interactions happen on a background thread except for subscriptions for the UI? I would ideally like to be able to do reducer and async actions all on a background thread, so as to not slowdown my UI, but sadly I have not found many resources on this topic. Seems that most examples I've seen do everything on the main thread, which is fine until it comes to IO stuff like network requests/db requests.

Hey y'all 👋 ran into some build issues earlier today with a KMM project + redux running on Apple silicon https://github.com/reduxkotlin/redux-kotlin/issues/96 Is this a valid issue? Happy to close if not. Also willing to look into this and contribute if I'm in the ballpark here. Was looking at https://github.com/ktorio/ktor/pull/2664/files as a reference but no idea if that's what's needed here.

For https://reduxkotlin.org

fun subscribe(onChanged: (AppState) -> Unit):StoreSubscription {
    return store.subscribe { onChanged(store.state) }
}

What would be the easieast way to make this more generic to listen to a specific state rather than the appstate? Obviously making each state inherit from a base class or interface is one way, but is there a more functional way?

Hi guys, GitHub says there currently is a 0.5.6 with some improvements for threadsafe stores. It doesn't seem to be on MavenCentral yet, right? Any chance to get it there, since the release was already back in October 2021?
