Hey!  I'm trying to add https://github.com/Kotlin/kotlinx-datetime to my kotlinjs project, but I'm getting errors related to joda-timezone.  I've added 

implementation(npm("@js-joda/timezone", "2.3.0"))

 to my 

jsMain

 dependencies, and also added a block to the beginning of my 

Main.kt

 file:

@JsModule("@js-joda/timezone")
@JsNonModule
external object JsJodaTimeZoneModule

private val jsJodaTz = JsJodaTimeZoneModule

I build with 

jsBrowserDistribution

but if I look at the build output javascript file, the very first few lines are:

(function (root, factory) {
  if (typeof define === 'function' && define.amd)
    define(['exports', '@js-joda/timezone', '@js-joda/core'], factory);
  else if (typeof exports === 'object')
    factory(module.exports, require('@js-joda/timezone'), require('@js-joda/core'));
  else {
    if (typeof JsJodaTimeZoneModule === 'undefined') {
      throw new Error("Error loading module 'turntaker-js'. Its dependency '@js-joda/timezone' was not found. Please, check whether '@js-joda/timezone' is loaded prior to 'turntaker-js'.");
    }if (typeof this['@js-joda/core'] === 'undefined') {
      throw new Error("Error loading module 'turntaker-js'. Its dependency '@js-joda/core' was not found. Please, check whether '@js-joda/core' is loaded prior to 'turntaker-js'.");
    }root['turntaker-js'] = factory(typeof this['turntaker-js'] === 'undefined' ? {} : this['turntaker-js'], JsJodaTimeZoneModule, this['@js-joda/core']);
  }
}(this, function (_, JsJodaTimeZoneModule, $module$_js_joda_core) {

which would seem to imply that the JsJodaTimeZoneModule is not being included, or certainly not being included prior to the check running

What kind of errors are you getting? What you're describing is what we also do in our project and it does work for us. Also the output javascript file looks pretty normal to me, at least it looks similar to our output.

The error is

Its dependency '@js-joda/timezone' was not found. Please, check whether '@js-joda/timezone' is loaded prior to 'turntaker-js'

. Given that these are the first few lines of javascript that are run, it is clear by inspection that js-joda is not being initialized prior to the dependency check. The dependency check is the first thing that happens in the module, and the

jsJodaTz =

line happens deep within the function scope, after the dependency check.

Does it only happen when building for distribution? I.e. does it work when running it using

./gradlew run

? For distribution we use the

assemble

task, not

jsBrowserDistribtution

, perhaps that's the difference?

It is a compose multiplatform project and 

gradlew run

 will launch the JVM variant.  I assume the equivalent you're suggesting would be 

jsBrowserRun

 which seems to build successfully and launches a localhost:8081 but returns a 404 ("Cannot GET /turntaker-js.js") for my main javascript output file.

I tried to reproduce it, but in the end, didn't manage to. Simple projects with the same configuration as yours work just fine, and the time zones are available from the browser.

have there been any follow-ups on this issue? I'm getting the same error but with joda/core missing in a compose for web/kobweb project
