rx-combinetuple-kt VS RxJava

I tend to use this lib https://github.com/Zhuinden/rx-combinetuple-kt

I'm writing an app in Java at the moment, and I must say, I miss the Kotlin collection functions + the ability to do positional decomposition for my tuples.

RxJava with RxRelay (and rx-combinetuple-kt)

As for the combineTuple, not sure what there is to deprecate, especially in the Rx variant that I use pretty much every day

MutableLiveData (java combiner/kotlin combiner) == BehaviorRelay (kotlin combiner) == MutableSharedFlow (kotlin combiner) conceptually, so it's not important to me which one it is, as long as you can throw combiners at it.

RxRelay + Rx-CombineTuple-Kt (+ Rx-ValidateBy-Kt) are things I use in my everyday life

3. RxJava This repository contains the source code for ReactiveX, a library used to create asynchronous and event-based programs with observable sequences. https://github.com/ReactiveX/RxJava

Is this similar RxJava, the reactive extensions library for https://github.com/ReactiveX/RxJava ? I have made that work in Clojure in production.

Since you mentioned java, there is RxJava and RxAndroid. Google general recommendation now is to use kotlin coroutines if you're considering writing your app with that.

It's very quick though. In terms of the correctness of the syntax, I've never seen an issue while translating a single file or a single function. When I took the entire RxJava code base 5 years ago, right clicked on the source folder and converted to Kotlin, I found lots of problems. File by file I've never seen any issues though, but I also haven't done it much.

You all beat me to MapStruct and Testcontainers. Honorable mention to RxJava, which I use in Desktop apps.

Concurrency: Kotlin coroutines for general use, Rx or Flow for reactive programming (you can technically use Rx for regular concurrency as well, but not really what it's meant for)

If you're just looking at making a service call on a regular interval and notifying the user when there's an actual change in data, you can also look into RxJava https://github.com/ReactiveX/RxJava. From here you can "subscribe" to your service call, and then every time you make your service call you can have it look for changes compared to the previous emission .distinctUntilChanged() and then only notify it's subscribers when it notices an actual change. From there you can trigger a local notification and push to a LiveData (assuming MVVM) or otherwise update the UI to match as well.
