Yes, and most likely you don’t want it 🙂

05/03/2018, 9:55 PMThanks, I an now trying to bring Kotlin to our codebase so need to create some “bridge” to our bootstrap (written totally in Scala). The idea is that other devs can start new microservices in Kotlin using my bridge so won’t use scala directly. We are working on it for a couple of days and it is much more pain than we could imagine

If it’s microservice, why do you need any specific interop other that http://12factors.net/?

05/03/2018, 10:29 PMIt is a good question. actually it is not obligatory. We are using gRPC for communications but there are some plugins which helps us generating interfaces for communication and skeletons. But the code they produce is Scala. I mean that other devs won’t write new services in Kotlin if we do not provide similar plugins for Kotlin. The thing we try to do is to reuse some similar parts of Scala generators for Kotlin but due to awful interop it would be really better to write it in Kotlin from scratch.
