What target should I use if I want to compile kotlin.js into a single service worker js file using the latest kotlin gradle plugin? Targeting browser produces a single .js file that has a reference to a window object, but the service worker file cannot contain a window object.

targeting common.js and using the compileKotlinJs task produces a single .js file that requires a "kotlin" module (require("kotlin"), I'm not sure how to include the kotlin module into the same .js file

If you use target browser() it build bundle with all dependencies included in build/distributions
By default it produces umd format
For worker you may need something else, maybe webpack default
So you can override it with

import org.jetbrains.kotlin.gradle.targets.js.webpack.KotlinWebpackOutput.Target
kotlin {
   target {
      browser {
         webpackTask {
            output.libraryTarget = Target.VAR
            output.library = "something" // while you define var name of js it should be valid js name, which you project name may not satisfy
         }
      }
   }
}

Thanks a lot. Library target Target.SELF did the trick. When using Target.VAR I was encountering a duplicate target file error when running build task
