Kotlin JS doesn't have ESClasses in K2, is it known ?

No, it's not known, what's the issue?

[Ayfri]

When using K2 in a JS target with useEsClasses = true it actually doesn't produces ESClasses

Thanks for reporting, we'll check.

@Ayfri, how do you define the useEsClasses ?
I've just try to add the next lines to the hello world application build.gradle.kts and seems like it works:

tasks.withType<KotlinJsCompile> {
    kotlinOptions.useEsClasses = true
    kotlinOptions.languageVersion = "2.0"
}

[Ayfri]

Here is my configuration :

kotlin {
	js {
		sourceSets.all {
			languageSettings {
				optIn("kotlin.ExperimentalJsExport")
				apiVersion = "2.0"
				languageVersion = "2.0"
			}
		}

		compilations.all {
			kotlinOptions {
				metaInfo = true
				typedArrays = true
				useEsClasses = true
			}
		}

		browser {
			commonWebpackConfig(Action {
				devServer?.open = false
				sourceMaps = true
			})
		}

		useEsModules()
		binaries.executable()
	}
}

Nevermind, I think I needed to delete build folder and restart JS build
