Redux (Guide to Redux for Android in Kotlin)

Adding Redux to your Project

1. Clone repository
2. Build 'reduxCore' module
3. Add @aar file to your project

How to use Redux

1. Define default state

val defaultState = ""

2. Define action

class AddSymbolAction : Action

3. Define reducer

class AddSymbolReducer : Reducer<String> {
    override fun reduce(oldState: String, action: Action): String =
        (action as? AddSymbolReducer)?.let { oldState + "$" } ?: oldState 
}

4. Create middleware

class LogActionMiddleware : Middleware<String> {
    override fun dispatch(state: Observable<String>, action: Action): Observable<String> =
        state.doOnNext { Log.d("TAG", action.toString()) }
}

5. Create store

val store = Store(
    defaultState, 
    listOf(Observable.just<Action>(AddSymbolAction())), 
    listOf(AddSymbolReducer()), 
    listOf(LogActionMiddleware()))

6. Call .bind method with scheduler

store
    .bind(AndroidSchedulers.mainThread())
    .subscribe({ /* render state */ }, { /* handle error */ })
