for targeting JS, do I have to use the @JsModule within my Kotlin code? when I compile using ./gradlew compileProductionExecutableKotlinJs my code only gives me the general JS functionality (objects, arrays, etc) not my actual module that I wrote in Kotlin.

Is DCE perhaps removing your stuff? If you're using the new IR, you might need to annotate with

@JsExport

or with legacy, configure the DCE (and maybe use

@JsName

)? https://kotlinlang.org/docs/javascript-dce.html#exclude-declarations-from-dce

do you have a specific example of how to implement JsExport and JsName within kotlin?
