set the channel description: Mu - Purely Functional Microservices for Kotlin. https://github.com/higherkindness/mu-kt

Let's get this party started! https://github.com/higherkindness/mu-kt

🎉

If you are in this channel is because in previous conversations you have expressed interest in Mu for Kotlin.

Guess I should get my ass on streams

While we don't have yet streaming in Arrow we can implement some of the endpoints and get the ball rolling

Mu aims to be the kotlin counterpart to https://github.com/higherkindness/mu

A full solution to purely functional backends based on microservices and a set of libs that help you manage the system in a cluster including monitoring etc.

Hey, guys how should I prepare myself for mu. I am pretty blank.

In other words, how do prepare yourselfs?

Does anyone know if we have something similar in Kotlin? https://github.com/47deg/pbdirect

Hi all, I'd like to echo the question @Imran/Malic posed regarding resources & getting myself immersed in Mu. My aim is to hopefully help out with the conversion to Kotlin to push my understanding. The Scala version currently uses the following libraries: avro4s cats-effect fs2 Monix What/How close is a Kotlin equivalent for each?

I am not sure about the whole capabilities of cats-effect, but I guess [arrow-effects](https://next.arrow-kt.io/docs/effects/io/). @pakoito is your guy in this matter.

There is not equivalent to avro4s AFAIK

Arrow-effects is still heavily worked on as we speak by me and Raul but most of what you need should be there already.

I started on Arrow-streams (an FS2 equivalent) but that's currently on hold to get arrow-effects in a more complete state.

Not sure if you really need both Monix and FS2. And if so let's make sure we provide the necessary things in effects or streams.

Monix is just there to provide an alternative to Fs2 in the interpretation of

Observable

endpoints that use uni or bidirectional streaming

in the Mu version all we need to implement Mu is in arrow-fx and will be also in arrow-streams. What we are missing is something like avro4s

Actually what we want to use for mu-kt is https://github.com/higherkindness/compendium in order to avoid to work on an avro4k library. With

compendium

, we should be able to just use its

gradle

plugin in order to receive the protocol directly on

kotlin

A

sbt

plugin is wip right now and the

kotlin

support along with a

gradle

plugin will become

@AdrianRaFo when you can, can you share the sample scala project that prints out the generated code so we can use for comparing with what we are generating in

mu-kt

? thanks!

Sure I'll do asap

From this https://github.com/higherkindness/mu/blob/arf-generated-sample/benchmarks/shared/src/main/scala/higherkindness/mu/rpc/benchmarks/shared/protocols/PersonServiceAvro.scala to https://github.com/higherkindness/mu/blob/arf-generated-sample/benchmarks/shared/src/main/scala/higherkindness/mu/rpc/benchmarks/shared/protocols/PersonServiceAvroExpanded.scala is what the current Mu macro generates (after some clean up to make it more readable)

You can download the branch on Mu

thanks @AdrianRaFo!
