Is it possible to mark certain classes / functions to be excluded from DCE?
I'm trying to build a KotlinJS library that will be consumed by handwritten JavaScript and unless i specifically console.log that class, it gets removed by DCE

@JsName("RoomState")
data class RoomState(
    val numberOfRooms: Int
)

fun main() {
  console.log(RoomState::class)
}

which now allows me to do

this.projectname.RoomState()

in pure JS, i exclude that console.log, RoomState is not available

kotlin {
js {dceTask {
    keep("ktor-ktor-io.\$\$importsForInline\$\$.<http://ktor-ktor-io.io.ktor.utils.io|ktor-ktor-io.io.ktor.utils.io>")
}
}
}

thats for ktor but you get the idea

[janvladimirmostert]

that's awesome, let me experiment and see if it can handle wildcards, then i can just put the package in

[janvladimirmostert]

seems like i need to do it for every single class that i'm exposing to the JS side, mmm, wonder if it can be achieved with a @NonDCE annotation or something

Thanks for the help, this is getting me in the right direction
