Hi all. We want to try using KMP to modify an existing Kotlin library to be consumed by multiple targets. It will be mainly used by some client applications (such as Android and JS: React Native, browser) 1. Is there any obvious problems that may arise? The code in current codebase is (somewhat) platform agnostic: only one library is JVM 2. First thing that I noticed is JSExport not allowed on suspend functions, does it mean our public API must be split between JVM and JS? (I.e. I have

suspend foo(): String

in

MyClass

. I would like to expose it to the developer using my library. I will need to create

expect MyClassAPI

that has different iml for JS and JVM:

fooAPI(): Promise<String>

and

suspend fooAPI(): String

. Both calling foo internally. We are still and research phase. Alternative would be to re-implement kotlin library in typescript, but I would like to hear from people with experience opinion on the topic. Thanks!

about second question: I believe that API shouldn’t be split, it is perfectly fine that your multiplatform library API has suspend functions. I suggest creating additional wrappers with

JSExport

in js source set for yours JS target and don’t use

actual / expect

for this task

The problem is that I have an

expect

class with suspend function which I want to export. Currently, I can't really do that because of JSExport restrictions.
