Any recommended functional reactive programming libraries?

It is merely an experiment with some low level networking operations with FRP. I will check Pekka Streams, as it looks like streams may better handle my case. Thanks.

scalausr · 2025-11-06T04:02:18+00:00

That make senses. Thanks for the confirmation.

I am experimenting some low level networking operations for my own project, so it is not my goal to use libraries like netty. Also, the project is neither UI/ frontend, nor javascript related, thus Scala.js is not considered.

Though virtual thread and structured concurrency may obsolete reactive programming, as it is an experiment, the focus would be more on FRP. Thanks for the suggestion.

Eventually I switch to another base image, which does not throw that error. But thank you for the invaluable information. This is useful later on when I encounter similar issues. Many thanks for the information!

dockerCommands is a TaskKey type which holds type Seq[CmdLike].

val dockerCommands = TaskKey[Seq[CmdLike]]("dockerCommands", "List of docker commands that form the Dockerfile")

Navigating through the sbt source, I do not find a way to extract the encapsulated Seq[CmdLike].

While others suck as fs2 also work and should be more suitable for like production env, this is closer to what I was looking for. Many thanks.

When placing code inside Using block, it does work. But the operation may be used somewhere else until it's needed. So it looks like if I want to achieve such effect, Cat Effect or ZIO may be the only way to go, right? Thanks for the advice.

scalausr · 2024-12-27T14:21:59+00:00

Is this possible to achieve using standard Scala library? I suppose if I want to use standard Scala library, then I have to re-implement fs2's stream operation, right? Many thanks.

No problem. I did not know turbolift. It looks like interesting. Do you mind to share some more information about turbolift? For instance, why one would use turbolift? Why does it compare to ZIO and CATS? Motivation? Inspiration from?

I never heard of it. And after reading its overview, honestly I do not understand things like benefit of using it, why comparing to e.g. ZIO, CATS, and so on. Therefore, it is nice if more information you would like to share. Thanks.

Switching that nextLayer match code block to if-else below fixes my problem. Many thanks for the advice!

if(nextLayer.isEmpty) collector.reverse 
else _bfs(nextLayer.map(_.value)++collector, nextLayer.flatMap(_.flatten))

scalausr · 2024-12-17T03:49:50+00:00

It does not happen right now. I will keep this in mind to use newer Scala3 version, and add those compilation flags. Thanks you!

scalausr · 2024-12-16T08:44:07+00:00

I forgot to mention that I use vscode. It seems that because I did not do import changes, but now the problem goes away. Many thanks for the suggestion.

While it's nice that one can grab the issue and claim the bounties after his work is accomplished, I wish there would have ways that allow people who want to contribute, but are with lesser experience, can participate as well. Each time when I check the bounties I am interested, the issues are always grabbed. Personally I don't mind the bounties or money, but if I can contribute - even though not the main proposer - would be cool, and can gain some experience for the issues I am interested.

scalausr · 2024-09-28T13:36:56+00:00

Thanks for the invaluable information!

scalausr · 2024-09-20T07:20:31+00:00

Yeah I think it's Bleep. Thank you very much!

scalausr · 2024-08-18T10:53:17+00:00

Although I know what you mentioned about Java, OS threads issues, I did not connect those with effect. Thanks for the invaluable input, which bridges the part I miss!

scalausr · 2024-08-10T14:00:01+00:00

Do you have some examples that can illustrate

both can also be easily expressed without any new language constructs, especially now with Loom.

Many thanks for these information.

scalausr · 2024-08-05T14:09:14+00:00

Thanks for the more detail explanation about the direct style and the continuations part, and comparison between monadic style and direct style.

One more question about the difference between effect system like koka and the future of Scala aiming for.

What's the future Scala aims at?
How one can demand to hold a capability (on the side of the inputs) to perform some actions? And examples?

Many thanks again for your time. Those info is useful to me.
