Heya! I'm trying to use JuulLabs/indexeddb in my Compose Multiplatform project with the Wasm target but having some trouble getting it to work.

My main struggle is to find where to define the dependency as I think that is my issue, but I'm not sure. First of all, I've defined it in the libs.versions.toml file like so:

[versions]
indexeddb = "0.7.1"

[libraries]
indexeddb = { group = "com.juul.indexeddb", name = "core", version.ref = "indexeddb" }

So first I'm unsure if the dependency should be defined in shared/build.gradle.kts or composeApp/build.gradle.kts . I think the latter, but I've tried both.

For shared/build.gradle.kts , I've added this under `kotlin > sourceSets`:

sourceSets {
    commonMain.dependencies {
        // put your Multiplatform dependencies here
    }
    
    wasmJsMain.dependencies {
        implementation(libs.indexeddb)
    }
}

And for composeApp/build.gradle.kts I've added this under `kotlin > sourceSets`:

sourceSets {
    val desktopMain by getting

    androidMain.dependencies {
        ...
    }
    commonMain.dependencies {
        ...
    }
    desktopMain.dependencies {
        implementation(compose.desktop.currentOs)
    }
    wasmJsMain.dependencies {
        implementation(libs.indexeddb)
    }
}

Then I do a Gradle sync and expect the dependency should work, but it seems not. To test I have a file composeApp/src/wasmJsMain/kotlin/App.wasmJs.kt where I try to open a database:

import kotlin.random.Random

import com.juul.indexeddb.openDatabase

actual fun databaseTest() {
    val database = openDatabase("test.db", 1)
}

But I get the errors:

Unresolved reference: com :3
Unresolved reference: openDatabase: 5

If I look under "External Libraries" in the Project window in Android Studio I do not see com.juul.indexeddb listed so I think the dependency isn't getting added.

I've also tried replacing implementation(libs.indexeddb) with implementation("com.juul.indexeddb:core:0.7.1") just in case it is a config issue, but that does not help either.

Does anyone have any advice or know what I'm doing wrong to add indexeddb as a dependency to my wasm module? Much appreciated

Unfortunately Indexeddb isn't yet targeting Kotlin/Wasm.

Created JuulLabs/indexeddb#157, but I'm not sure if we'll be able to get to it in a timely fashion.

You're welcome to try adding the target and reporting back if you have any success with that.

PRs are also welcome.

Ooh okay, I must've misunderstood something. I thought I saw it mentioned that it did support Wasm, my mistake! Thanks for your time
