I'm running into ClassCastExceptions when using 4.0.0-beta.5 and onwards for Kotlin/Js (specifically creating a website with <https://github.com/varabyte/kobweb|Kobweb>)

Kotlin 1.9.23 since kobweb is still blocked for 2.0

I'm seeing a similar issue <https://github.com/apollographql/apollo-kotlin/issues/5801> except that I don't have to call any build function, for me it crashes as soon as i have the dependency. is it certain that this is fixed for K2 already?

Exactly I was about to link this issue :sweat_smile:.  Unfortunately, with JS, AK 4 needs your project to use Kotlin 2.

alright, I see. beta.4 is still functional so I guess I can wait out a bit longer

it's building on top of compose html, so you get a proper dom and not a chunky canvas ^^

yeah - Do you know if kobweb can't update to Kotlin 2 or is it just that it's not done yet?

_Users are asking us when K2 support is going to land, but we are currently blocked due to a pretty major incremental compilation issue. You can learn more <https://youtrack.jetbrains.com/issue/KT-68463|here> and <https://youtrack.jetbrains.com/issue/CMP-1449/compiler-bug-kotlin-cache-stableprop-workaround|here>. We are keeping a close eye on it and will support K2 as soon as we can!_

That sounds cool! I'm playing with K/JS a little bit these days, I'll probably have a look at Compose HTML too.

yeah Kobweb is definitely something to check out for web apps. I already have a project running it with the apollo client, in combination with mobile and desktop targets. prior beta.5 ofc but other than that it's working great

very cool! If it's a public thing don't hesitate to share a link, we're always curious to see the lib used in the wild :slightly_smiling_face:

you can see the site <https://app.fluen.se/marketplace|here>, but I haven't open sourced it yet :sweat_smile:

<@U02RTVCF717> Just curious: could you still use 2.0 in your build but use the kobweb dependencies compiled against 1.9? K/JS has backward binary compatibility now so it _should_ work I think?

I don't think so. I would also need to bump compose to 1.6.10 or smth which is compatible with kotlin 2.0, however the last compose version compatible with kobweb is 1.6.2 :/

as soon as you throw in compose there's a scary limbo between versions :sweat_smile:
But I'll just wait it out, it's still fully functional

Yep, didn’t think of the compiler plugins coupling there :sweat_smile:
