Follow up question regarding JsExports.

Asking to see if someone already asked so that I may not open a duplicate ticket

currently exporting

val lambdaFunction: (user: User)->Unit

yields the following typescript definitions

readonly lambdaFunction: (p0: User)-> void

Which hurts readability.

I would expect it to be exported to

readonly lambdaFunction: (user: User)-> void

Is there already a ticket for this?

[Big Chungus]

Hmm, maybe try adding @JsName("user") on that argument?

[andylamax]

fails with: Unsupported [annotation on parameter in function type]

[Big Chungus]

Ah, was a wildcard anyways...

[Big Chungus]

Can you not just use regular fun instead?

[andylamax]

I wish I could, javascript doesn't play well with an exported unbounded functions which calls member variables using the this keyword.

[andylamax]

ends up throwing undefined all over the place

[Big Chungus]

Hmm, bind it to class via asDynamic() in init block?

[andylamax]

As expected, kotlin syntax wont allow

init {
  doSomething.asDynamic().bind(this) // error
}

fun doSomething(user: User) {

}

Fails with: Function Invocation expected

[Big Chungus]

Ah, you need fun reference, so ::doSomething

[Big Chungus]

Just guessing
