Following the js-modules reference page I was able to declare the function

getInfo

from module

ytdl-core

. I have some problems when calling it but I'd like to ask you another question. I don't want to pollute the global namespace with module-specific function, so I used this syntax to declare the whole module and its function(s).

@JsModule("ytdl-core")
external class Ytdl {
    companion object {       
        fun getInfo(name: String, options : dynamic, callback : (dynamic, dynamic) -> Unit) : Unit
    }
}

Now I can read all javascript properties of

Ytdl

with

Object.getOwnPropertyNames()

(and

getInfo

in among them) but I don't know how to refer to `Ytdl.getInfo`: both

Object.getOwnPropertyNames(Ytdl.getInfo)

and

Object.getOwnPropertyNames(Ytdl::getInfo)

fail to compile. The first is assumed to be a function call (lacking its arguments), the second causes a "Unresolved reference: getInfo". Am I missing something?

@melatonina could you show generated code for second?

Why not

external object Ytdl

?

Yes, declaring an

external object Ytdl

was more appropriate. Sorry for all these questions that may appear to be silly to you. It's still not clear when I should use

external class

and when I should use

external object

. I'll re-read that page.
