All the Compose Web samples seem to use multiplatform plugin......is that necessary or can you just have module containing compose web code with dependency then on a separate multiplatform module?

[Javier]

Maybe it is using that instead of kotlin("js") for the same reason that desktop samples are using multiplatform instead of kotlin("jvm"), because it doesnt work correctly and need to be fixed?

[Javier]

(well, I think it should be fixed already 🤔 )

[John O'Reilly]

fwiw the compose desktop project I have seems to be ok with kotlin("jvm") ....had tried kotlin("js") but running in to some issues

[Javier]

it is closed so it should work

[John O'Reilly]

yeah, this is what I have here for that https://github.com/joreilly/PeopleInSpace/blob/main/compose-desktop/build.gradle.kts

[John O'Reilly]

seems to be working ok (with compose desktop using jvm plugin that is)

[John O'Reilly]

k, getting a bit further using kotlin("js") ...at least one change needed was that js in the multiplatform module needed to be updated to js(IR)

[John O'Reilly]

hmm, but doing that causes other issues when trying to resolve dependencies in the common module

[Oleksandr Karpovich [JB]]

Hi John! Currently, the compose gradle plugin with web support enables the compiler plugin for js(ir) targets only when the multiplatform plugin applied (https://github.com/JetBrains/compose-jb/blob/master/gradle-plugins/compose/src/mai[…]lin/org/jetbrains/compose/ComposeCompilerKotlinSupportPlugin.kt). As I remember, it was an intentional decision. But I can't recall an exact reason for now. I'll double check with my colleagues.

[John O'Reilly]

Thanks @Oleksandr Karpovich [JB]. I'd actually gone back to using multiplatform plugin but running in to issues I think because not all dependencies I have support IR compiler

[John O'Reilly]

(am depending on another multiplatform module I have)

[Oleksandr Karpovich [JB]]

I see. you're right, the JS dependencies need to have IR variant in order to use them with compose-web.
does that multiplatform module reside in your project? (I mean is it possible to try out the js(IR) with that module?)

[John O'Reilly]

yes, it's multiplatform module in same project....I'm trying js(IR) there but running in to issues with a few of the libraries that I don't think support IR yet

[John O'Reilly]

resolved one of those by updating to later version that's supporting IR but still have 2 more that don't yet

[John O'Reilly]

I created local builds of those 2 libraries with IR enabled and it's running now
