Trying to switch my web common code to using kotlin-wrappers:kotlin-browser from kotlinx-browser (to get rid of copy/paste common logic for js and wasmJs targtes)
kotlin-wrappers:kotlin-browser claims to be common for both js and wasmJs targets, but when trying to compile for wasmJs target got compilation exception

Can't link symbol web.streams/ReadableStream.cancelAsync|cancelAsync(js.errors.JsError?){}[0]

I've found issues about it: https://youtrack.jetbrains.com/issue/KT-76567 and https://youtrack.jetbrains.com/issue/KT-68995/ReadableStream-unavailable-in-Kotlin-Wasm
So i wonder if anybody had success with using this lib for wasmJs target? If yes then how to workaround this issue?

P.S. I'm not using ReadableStream class in my app

It's a wrappers issue https://github.com/JetBrains/kotlin-wrappers/issues/2761 caused by a fact it's using Seskar compiler plugin to generate things.

Currently the only workaround is using production builds only.

In fact we need some additional compiler support, which already exists in Kotlin/JS

JFYI: We have a plan to add K/JS target to kotlinx-browser, but it may take a couple of months since it requires some changes on the toolchain side.

Hello, Zalim! Good news! Is there any YT for it?

[Robert Jaros]

Why do we need two official JB libraries for the same thing?

[Sergei Grishchenko]

And one unofficial 🙂

[Robert Jaros]

It's on JetBrains Github account so it is official 🙂

[Sergei Grishchenko]

Ok, kinda 🙂
actually we have 3 then
• org.w3c - only for JS
• kotlinx-browser - only for WASM (at least for now)
• kotlin-wrappers mostly for JS and partially for WASM with some issues 🙂

[Sergei Grishchenko]

sorry, first link is wrong

[Sergei Grishchenko]

I tried to figure out what I suppose to use in K/JS now if I want to refer to Window and I didn't found it 🙂 To be honest it seems some changes are happening in terms of declarations for browser environment in Kotlin team and I didn't get them yet.

[Sergei Grishchenko]

It seems something like this...

@PHondogo

Is there any YT for it?

Here they are:
• KT-75479 Add Kotlin/JS target into kotlinx.browser library
• KT-75480 Add shared source set for js and wasmJs target

@Robert Jaros for sure, it would be better to join the efforts, and that’s what we need to discuss.
