When will Kotlin/JS have the RTCPeerConnection classes and functions available?

[Big Chungus]

Is that some native nodejs API?

[Miquel Àngel Román]

No, it’s browser and it’s available without any dependencies

[Big Chungus]

P.S. You can use them now with your own external declarations. Just because kotlin.js can't see them does not mean they're not there.

[Big Chungus]

e.g.

external class RTCPeerConnection()

I’ve managed to instantiate items using the js(“code”) workaround, but I’d like to get an automated way of getting the thing typed

[Miquel Àngel Román]

Tried Dukat but had no luck

[Big Chungus]

Dukat does not see web APIs

[Big Chungus]

You have to declare your own externals or use dynamic types

[Miquel Àngel Román]

It can through your dependencies:

implementation(npm("@types/webrtc", "0.0.30", generateExternals=true))

[Miquel Àngel Román]

Although no way I could import anything of the generated under build/externals

[Big Chungus]

Why can't you import them? What's the error/issue?

[Miquel Àngel Román]

I managed to import them but it’s transpiled as an interface complaining that there are no constructors

Are you sure it has a constructor on js? It might be something produced by factory functions only

[Miquel Àngel Román]

[Miquel Àngel Román]

I might be missing something but terminal autocompletes the “constructor” field as well

[Big Chungus]

Then it's a bug with dukat. Declare your own external with constructor

[Miquel Àngel Román]

Thanks!

if webrtc has a IDL, try using the kotlinx.browser generator

[ephemient]

although it still uses dukat at some point, so if the issue is there instead of in the @types/webrtc definitions, then that may not help

[Miquel Àngel Román]

What’s IDL?

[ephemient]

interface definition language, almost all web interfaces use it

[ephemient]

according to https://www.w3.org/wiki/Web_IDL#Dependent_Specifications webrtc is also defined in idl
