A modern programming language that makes developers happier.

Hi everyone! I'm looking to implement a long-living server stream with gRPC that clients can subscribe to, and I know coroutines is an option for that.

Context: there is a group of users with users and a lead user, when the lead starts and action `performAction()` which is a unary RPC. I want to notify the other users with information about that action. I would expect those members to be subscribed to another long-living RPC that facilitates sending that information.

Do you have any examples of how can achieve that in Kotlin? I was looking into something like:
<https://dev.bitolog.com/grpc-long-lived-streaming/>
<https://sultanov.dev/blog/grpc-long-lived-streaming-using-observer-pattern/>

But those implementations are written in Go and Java, and I'm struggling to find examples in Kotlin

Like this one?

There is the more menu on their <https://grpc.io/|home page>, next to the first 4 languages. If you cluick there you can select kotlin.
