Can I have several Output Files when using Kotlin JS

I recently started using Kotlin for a Chrome-Extension-Project. For this I need the kotlin js transpiler not to output just one js file with all the code in it, but two distinct files.

Is there currently an option to do this easily without using a build-tool like gradle or maven?

By far the easiest approach would be to have multiple (two) modules/sub projects

Yeah, that’s what I ended up doing. Unfortunately this method is far from ideal.
Being able to configure the build somewhat, will definitely be important for the future.

Is there any updates on this?
