hi. is there a way to test Kotlin (JS) code, so that it's easily integrated with Gradle and IDEA? I've seen https://github.com/epabst/kotlin-showcase/blob/master/webclient/src/test/kotlin/QUnit/qunit.kt and don't understand what it's doing

Hello?

K/JS noob here: Has anyone successfully converted OpenLayers typescript definitions to kotlin? I've tried with these two definitions and can't seem to get either to work properly. https://github.com/jumpinjackie/jsdoc-typescript-plugin/blob/master/typings/openlayers.baseline.d.ts https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/openlayers/v3/index.d.ts

Good morning 🙂. Weekend project created puzzling error, how to resolve the following ts2kt error: ts2kt: Merging Variable and ??? unsupported yet, a: var Window.VRFrameData: Any get() = definedExternally; set(value) = definedExternally , b: var VRFrameData: Any = definedExternally

hello all, I’m using the react-kotlin wrappers in my web project. I have a ‘select’ html element, but can’t seem to get the value out of the onChangeFunction event. Has anyone done this and can help me out?

In case someone is interested to tinker with BabylonJS using KotlinJS here is alpha version of bindings: https://github.com/tlaukkan/babylonjs-kotlin

I create an app with using create-react-kotlin-app. How to use kotlinx.coroutines in my project?

I think I found a bug on kotlin.js https://try.kotlinlang.org/#/UserProjects/7g3b3r1k6oqfq82ltabjfm44qt/1175fthomfiusfk2n0c268bqc4 When running on the JVM the double conversion to string is always good (with .0). Running as js, the conversion to string doesn’t put the “.0”

fun main(args: Array<String>) {
    val dbl = 1.toDouble()
    println("M$dbl")  				// M1.0 OK
    println(moveTo(1.toDouble())) 	// M1   KO
}

fun moveTo(x:Double) = "M$x"

How can I set the id of an element from the kotlin React DSL?

So I stole the configuration of the KotlinConf app, and made a stub ktor project that serves it, but when it serves the root page nothing actually comes up

Hi. Is there any progress on issue KT-19672? I want to use Kotlin for a web front-end project, but the lack of Promises is a problem.

I have a problem using kotlin js incremental compilation with webpack watch. When changes occurred kotlin compiler removes target js file before compilation and webpack build fails in watch mode. Is there some workaround?

Steps: 1. run gradle in continuous mode 2. run webpack --watch 3. wait for first build 4. make changes 5. webpack build error:

Module build failed: Error: ENOENT: no such file or directory, open ...

And XMLHttpRequest sends a POST to

/#/newlog

instead of

/newlog

What is the best way to work in "watch" mode? Kotlin incremental js compilation works fast, but webpack is extremely slow on kotlin std lib (1,5 Mb, ~5s to rebuild in watch mode). Kotlin DCE speeds up webpack build, but slows down incremental js compilation...

How to get value from List from javascript side?

kotlinArray[0]

kotlinArray.get(0)

- not works real method have name

get_za3lpa

I am unable to add operator with @JsName

When I build it, it is starting but not working because it is shouting that it cannot find dependencies:

How should I deserialize JSON into a Kotlin data class?

Is there a CDN that will serve

kotlin.js

&

kotlin.meta.js

for me?

guys, is there typesafe css builder? like it done in #tornadofx

Is there any build-in way for access to

self

(DedicatedWorkerGlobalScope) inside Worker? Or just use external declaration for

self

?

private external val self: DedicatedWorkerGlobalScope

We have

kotlin.browser.window

in stdlib, maybe make sense also add

kotlin.js.self

(WindowOrWorkerGlobalScope) or

kotlin.js.worker

(DedicatedWorkerGlobalScope)

hey guys this might have been answered before but since there’s not that much history i apologize in advance is there a kotlin equivalent to a top-level anonymous function:

(function() {
  // My code here
})();

Wait, hang on. It works properly when I build from console, but not when I build from IntelliJ. Wat?

I am trying to setup a common module and a js module that uses data classes defined in the common module but compilation fails with Unresolved reference. Anyone have an example of this working ?

@spand It was considered. Due to some Gradle restrictions one still has to create a separate module for each implemented platform. "depend on that common module directly" -- however that may be supported one day, so that you add a dependency on a common module, and the correct dependency according to the current platform is determined automatically. If you have further questions about multiplatform projects, let's continue in #multiplatform

Hi! I try to use kotlin with react and I fail to use a 3rd party library. What I'd like to use is react-md. I guess, that I have to use the @JsModule annotation and build my own wrapper classes. Is something like this the right way? (It is not working by the way because the number of parameters is not right.)

@JsModule("react-md/src/js/Cards/Card")
external val Card: RComponent<RProps, RState>
fun RBuilder.card() = child(Card::class) {}

I was surprised to find that classes cannot implement a function interface on the JavaScript platform. This makes making existing libraries multiplatform difficult. Is this limitation likely to be lifted any time soon?

Is there a tool to convert Flow type annotations to Kotlin extern definitions?

Anyone knows how to work on forms in React with Kotlin? I found view on Thinker but this approach is not working (no value property on input). Probably because API changed. https://github.com/Kotlin/kotlin-fullstack-sample/blob/master/frontend/src/org/jetbrains/demo/thinkter/Register.kt
