Kotlinx.coroutines Alternatives

Reviews and mentions

• Updating my tech stack: RxJava vs Flow
  reddit.com/r/androiddev | 2021-10-01

  The catch operator ignores CancellationException which is used for cooperative cancellation in coroutines and flows. If you use try/catch, make sure you're not accidentally swallowing those exceptions. The same goes for runCatching, which catches all Throwables.

• All About Opt-In Annotations
  dev.to | 2021-09-30

  Some of the best examples of opt-in APIs are in first-party Kotlin libraries. A great example is the kotlinx.coroutines library, which uses four different opt-in marker annotations across its API.

• Our first year with Kotlin Multiplatform

  The second one is about the memory model in Kotlin/Native (in our case for iOS), and the possibility of using a background thread for coroutines. This one doesn't have a final implementation yet either, but a final solution is on the way. However, a temporary solution from JetBrains in the form of a special native-mt Coroutines build has proven to be sufficient in not delaying the use of Kotlin Multiplatform any further.

• Trying out the experimental new Kotlin/Native memory model
  dev.to | 2021-08-07

  It's pretty neat seeing this in action! As the Kotlin team promised previously, existing code written around freeze() in the strict memory model still appears to behave the same in the new experimental model. But we also now have the ability to pass unfrozen things across threads. This should mean that, once the model is finalized, existing code won't need to migrate immediately. However, early adopters of the experimental model will likely need to wait for any concurrency libraries they depend on to update, or else they'll still need to handle the existing freeze() behavior. That work has already begun in kotlinx.coroutines.

• How We integrated Kotlin Multiplatform Into Profi

  For asynchronous operations, we used kotlinx.coroutines and kotlinx.serialization for the serialization and deserialization processes.

• What are the things you don't like when working with kotlin?

  Now for KMM, it is very much an alpha product even though many companies have found success in its use. The gradle build configuration can be very tricky to do unless you know what you're doing and the templates in intellij are rather limited at the moment of what you can setup in a new project. Kotlin native multithreading is still a rather complicated topic if that is something you need to be stable, but there is an open issue to address this and experimental branches you can use. Now the positive side to KMM is the ability to share logic between every platform and just needing to implement each UI natively. There are also great architecture solutions out there like Decompose which allows you to write a very large portion of your app in kotlin.

• It is possible to mix Java Future with Kotlin for async?

  Maybe this helps https://github.com/Kotlin/kotlinx.coroutines/blob/master/integration/kotlinx-coroutines-jdk8/README.md ?

• Kotlin Team AMA #3: Ask Us Anything

  for /u/qwwdfsad Coroutines Why don't SharedFlow and StateFlow suspend waiting for all current subscribers to have completely processed the latest value? Will they ever? The docs said so but then when an issue was raised (https://github.com/Kotlin/kotlinx.coroutines/issues/2603) the docs were changed instead of the code. :(

  We believe that most of "useful operators" that you mention are very domain-specific and are better suited for domain-oriented extension libraries on top of Flow. We've specifically designed Flow to make writing your own operators trivial. However, if you do feel that some general-purpose operators are missing, then please give us feedback at https://github.com/kotlin/kotlinx.coroutines/issues

  We have the general compatibility guide regarding experimentality that explains the potential trade-offs and pitfalls. TL;DR it's pretty safe to use in production apps (not libraries that are shipped in binary form for other apps/libs) as long as you are okay with a periodical check of the changelog before coroutines update.

• Coroutine 1.5.0 releasee
  reddit.com/r/androiddev | 2021-05-14

  Corutine 1.5.0 along with other awesome kotlin libraries has also been released Changes at https://github.com/Kotlin/kotlinx.coroutines/releases/tag/1.5.0 Major apis changes(deprecation around Channels apis)

• Coroutines for beginners- the only article you need to get started!
  reddit.com/r/androiddev | 2021-05-02

  If you create a context without specifying a Job, you basically get GlobalScope.

• Experimenting with Coroutines and traditional Spring transactions - feedbacks welcome
  reddit.com/r/Kotlin | 2021-05-02

  Based on this I created my own ThreadContextElement for spring transactions. POC is here.

• How do you guys build JS async interop?
  reddit.com/r/Kotlin | 2021-04-22

  For Java you can use CoroutineScope.future() and CompletableFuture.await() More Java interop: https://github.com/Kotlin/kotlinx.coroutines/blob/master/integration/kotlinx-coroutines-jdk8/README.md

• In a MutableStateFlows, what's the difference with setting the value and calling emit?
  reddit.com/r/Kotlin | 2021-04-21

  Also the StateFlow's emit is implemented by just setting its value property.
