What is the correct type to use in Kotlin in order to get an exported type as {} in JavaScript? I've tried Map, but IJ is complaining "Exported declaration uses non-exportable parameter type: Map<String, String>" Instead of List, I have to use Array to get [] in JavaScript / TypeScript, what type will give me a JavaScript object, {}

try https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.js/-json/

that works for the KotlinJS side, is there something that will work for common, jvm and js (especially for @JsExport)?

Why not record? external interface Record<T>

it's starting to sound easier just to have separate APIs for JS and JVM side, then I can use Map for the JVM and JSON for JS side. already had to do JS

fun get(url: String): Promise<HTTP>

JVM

suspend fun get(url: String): Result<HTTP>

since suspend functions doesn't export thanks for the feedback!

Is it open-source? I'd try to implement support for Map in KustomExport but I don't have a real usage right now 🙂
