I’m trying to generate a typed definition file ( typescript ) for my multi platform KotlinJS code. I wasn’t successful with any of the 2 plugins I found.

Any of you had any luck ? Do you generate .d.ts file for your Kotlin code and how?

I know Kotlin 1.4 should fix this but it’s not released yet and we don’t have a specific date right now.

Thanks!

You could try the EAP 1.4-M1 if that is an option for you. This does create the d.ts file

Do you use multiplatform plugin or js?

[Sebastien Leclerc Lavallee]

I’m using the multiplatform plugin

[Sebastien Leclerc Lavallee]

I’d have to check my dependencies and see if they have a preview that support 1.4 🤔 . ..

[turansky]

Only JS plugin can generate *.d.ts as I know

[Sebastien Leclerc Lavallee]

Is this the case also for Kotlin 1.4 ?

[turansky]

Yes

[Sebastien Leclerc Lavallee]

🤔 So I’d have to create a JS only module that has dependency for my multiplatform target and this would work

Not so simple 🙂

@JsExport annotations analized only for current module now

[Sebastien Leclerc Lavallee]

Meh… that’s sad… at least from a multiplatform point of view

[Ilya Goncharov [JB]]

multiplatform plugin supports d.ts generation

@JsExport works with transitive module (not only current module) too, but only with js specific sources
Annotation is not accessible in common code now

@Ilya Goncharov [JB] Thanks for the clarification! So that mean I’ll have to create a JS only module and depend on my multiplatform

[Ilya Goncharov [JB]]

You can try pre-release version of 1.4
1.4-M1 was released already

Check it out with Kotlin/JS section

In 1.4 M1 JsExport is accessible inside existing multiplatform project in JS sourcesets. Creating a separate JS-only project is not necessary.

[Sebastien Leclerc Lavallee]

Oh great!

[Sebastien Leclerc Lavallee]

Is there a way to test 1.4 M1 without updating the whole project and all it’s dependencies?

[Ilya Goncharov [JB]]

If you want to get generated d.ts you need new compiler, and it requires new library format
So I am afraid that there are no such ways

[Sebastien Leclerc Lavallee]

That was my understanding, but I was just asking to be sure 🙂 Thanks!
