in the new multiplatform gradle setup, how do we specify js options?

Yeah, it’s kinda messy right now, but we are working on the proper DSL. For now try to use this (replace js with the name of your js target):

configure([js]) {
            tasks.getByName(compilations.main.compileKotlinTaskName).kotlinOptions {
                sourceMap = true
            }
        }

By js target do you mean:

[gbaldeck]

fromPreset(presets.js, 'js')

Ok so this worked actually

targets {
        fromPreset(presets.jvm, 'jvm')
        configure(fromPreset(presets.js, 'js')) {
            tasks.getByName(compilations.main.compileKotlinTaskName).kotlinOptions {
                sourceMap = true
            }
        }
    }

Thanks for your help

btw, is there a list of such options to be found somewhere?

[gbaldeck]

Not officially, but if you go here https://github.com/Kotlin/kotlin-frontend-plugin and in the readme look at the first code section you'll see compileKotlin2Js. The kotlinoptions in there are the ones you can use. Just without the kotlinoptions prefix.

[gbaldeck]

also, I haven't tried, but the kotlinfrontend plugin will probably still work

I decided to setup my own webpack config with npm though, which is what i would recommend until the new kotlinjs multiplatform dsl gets sorted out
