I have

Exported declaration uses non-exportable property type: List<Carousel>

and

data class Data(
    val carousel:List<Carousel>
)

Carousel itself is marked with @JsExport as well, am I not able to export lists?

[dan.the.man]

It does appear to be correctly generating the d.ts?

class Data {
        constructor(carousel: kotlin.collections.List<models.Carousel>);
        readonly carousel: kotlin.collections.List<models.Carousel>;
        component1(): kotlin.collections.List<models.Carousel>;
        copy(carousel: kotlin.collections.List<models.Carousel>): models.Data;
        toString(): string;
        hashCode(): number;
        equals(other: Nullable<any>): boolean;
    }

I think it would be simpler to use from JS/TS if you use Array in such API.

[dan.the.man]

Yeah, that's what I ended up doing

[bashor]

Kotlin’s List is not exportable now.

[dan.the.man]

If I pulled in kotlin std in JS, it should have kotlin.list right?

[bashor]

what do you mean?

[dan.the.man]

https://kotlinlang.org/docs/reference/collections-overview.html In JS, if you pull in kotlin std lib you should be able to use the List<T> right? or am I mistaken

[bashor]

You can use it from Kotlin code, but not from JS side now, since collections are not exported.

[bashor]

^^ it’s only about the new JS compiler

[bashor]

In general, for API designed to use from JS it’s better to use Kotlin types mapped to JS “primitives” and your own types.
