Hello, I recently discovered Kotlin and IDEA and been loving them both. i'm currently using Kotlin for a project where I have an API that handles the business logic and, apparently, people at administration don't fancy doing cURL requests and want a web and an android client to consume it. Am I better off doing the api and the two clients each in a separate project, for three total, or all in kotlin multiplatform?

that is a deep architectural question. In my experience, people usually have the server side stuff together, then have the android app be its own then. It depends entirely on the technology you’re using for the web. If you want the web to be a Single Page Application, you could build it separately and host it separately, or you can build and host it as part of the ktor application. I wouldn’t do an SPA in Kotlin/JS, though. Too much faff and learning curve at the moment.

I'd keep the service logic and the clients in separate projects personally. Separating server from business logic, from an arch and DDD perspective is actually a good thing, that way if you to change how that business logic is delivered at some point (say they want an android app that works offline), then you don't have to worry about breaking the business logic back out of the service logic if you happen to get another dev in there that breaks your encapsulation, they can't because it's different projects (and you can't either if somebody comes yelling about faster)

That's what I thought. Also Multiplatform is in beta.

Ktor is good

Oh, I meant the question above, I have business logic and the ktor server in separate projects, which one do I migrate to the other?

Personally I prefer to keep the web logic and the business logic next to each other. (In gradle I typically have a multi module project with two sub modules, where one keeps the business logic and the other one the web/ server logic)

yea, that works too, Architecturally speaking, as long as you can't accidentally reference them directly across, you're in a better spot

Yeah, I have them separate.

You are sure that the ktor server is exposing a data class and not a standard class?

Yeah, the server used to serialize the class no problem before.

And what does the exception look like?

Let me recompile, I was checking the code when it was just the server and it worke.d

Could you check your packages briefly? It might be the case that there are two kinds of clients in the same package due to some dependencies?

Maybe, that will have to wait until monday tho.
