How would I go about making a common module that both js and wasmJs targets depend on? I want to make a class that can be accessed via both js and wasmJs modules (since it uses Float64Array), but not put it in the common module, since Float64Array wouldn't be accessible for my jvm module.

You’re using Kotlin 1.9.20?

Yep!

Then it's probably this (untested):

@OptIn(ExperimentalKotlinGradlePluginApi::class)
applyDefaultHierarchyTemplate {
    common {
        group("commonJs") {
            group("js")
            group("wasmJs")
        }
    }
}

I managed to get it to show up! I think that it technically works, but Float64Array isn't recognized, since it's a 'blank' module with no dependencies.

I read on the Multiplatform Heirarchy page on Kotlin's docs that sharing a source set between several JS targets is not possible, assuming they're including WASM as a JS target..

When I put my class in the JS module, it pulls Float64 array from kotlin-dom-api-compat, but in the WASM module it pulls from kotlin-stdlib-wasm-js, which makes me think this is frustratingly not possible as they're two different classes

Hmm, I haven't tried that combination myself. Maybe Wasm is not yet fully integrated with the other targets. (I'm using separate Gradle configurations for wasmJs and js as I'm using different Compose versions with those.)
