Production-Ready(?) Native Single-Atom-State Purely Functional Reactive Composable UI Components, or PRNSAASPFRUICC

The native UI toolkits on Android and iOS are frustratingly imperative. Unfortunately, there has been little architecture evolution (unlike the web). However, nothing(ish) is stopping us from bolting something "nice" on top. By nice I mean single-atom-state purely functional reactive composable UI components. In this post, I'll explain what this title means, the inspiration behind the design of the framework, an example component, and dive a little into the framework's implementation.

Right now, there only exists a Kotlin (Android) implementation, but a Swift port will be relatively straightforward and will happen soon.

Let's break down the title:

• "Production-Ready"

public class Pager<I, O> {

    private static final Observable FINISH_SEQUENCE = Observable.never();

    private PublishSubject<Observable<I>> pages;
    private Observable<I> nextPage = finish();
    private Subscription subscription = Subscriptions.empty();

    private final PagingFunction<I> pagingFunction;
    private final Func1<I, O> pageTransformer;
