When upgrading my project from Kotlin 2.0.0 to Kotlin 2.0.10-RC my integration with some JS modules is broken. E.g. export 'RsupProgress' (imported as 'RsupProgress') was not found in 'rsup-progress' (possible exports: Progress). What can be the cause of this? Can't find anything in 2.0.10-RC release notes.

Could you please share an example project where this issue can be reproduced?

[Robert Jaros]

Unfortunately it's not that easy. It's this project: https://github.com/rjaros/kilua , but there are some other dependencies I need to consider. I'll try to make a branch.

[Robert Jaros]

This line is probably the root cause of the problem:
https://github.com/rjaros/kilua/blob/main/modules/kilua-rsup-progress/src/commonMain/kotlin/dev/kilua/externals/RsupProgress.kt#L51

[Robert Jaros]

It seems like my @JsName annotation (which is an expect/actual typealias for kotlin.js.JsName) is not working anymore.

[broadway_lamb]

Can I ask you to create a ticket on kotl.in/issue? Seems like an important issue.

[broadway_lamb]

Thank you!

[Robert Jaros]

What's strange, I'm using the same expect/actual trick for @JsModule annotation, and it seems to work.

[Robert Jaros]

Or perhaps it's the problem with kotlin.js.JsName itself ...

[broadway_lamb]

Hm. This is strange. As far as I know, you should be able to use JsName in common code. Could you please try annotating your RsupProgress class as @kotlin.js.JsName and see if it works?

[Robert Jaros]

Because I'm using also the original annotations and it doesn't seem to work as well.

[Robert Jaros]

Yes, the original annotation doesn't work as well.

[Robert Jaros]

Here I'm using the orignal annotations: https://github.com/rjaros/kilua/blob/main/modules/kilua-trix/src/jsMain/kotlin/dev/kilua/externals/Trix.js.kt

[Robert Jaros]

both @JsModule and @JsName - and I have an error: export 'Trix' (imported as 'Trix') was not found in 'trix' (possible exports: default)

[Robert Jaros]

Compiling with 2.0.10-RC2-532 fixed the problem. Thank you!. I'll just have to wait till next release.

[Robert Jaros]

It also fixed KT-69876, which also affected my project after upgrade.
