You can apparently bump Dukat to a later version by setting

rootProject.kotlinNodeJs.versions.dukat.version = "<VERSION>"

Could someone here share their gradle setup for new kotlin.js plugin?

I noticed that the

config.output.filename

property in

webpack.config.js

auto generated file changed in the kotlin JS 1.3.50. Is there any way to customize it?

config.entry.push("/Users/felipecosta/github/chat-app/build/js/packages/chatapp-frontend/kotlin/chatapp-frontend.js");
config.output = {
    path: "/Users/felipecosta/github/chat-app/frontend/build/distributions",
    filename: "frontend-1.0-SNAPSHOT.js"
};

I’m using the

kotlin-multiplatform

plugin, and I’ve noticed that my js tests aren’t running on 1.3.50. Is there anything special I need to do to make them run?

Hi there. I believe this is a code generation problem in the JS backend: https://pl.kotl.in/luUpaughw `chainc()' method call is not being emitted.

are there any examples of kotlin compiled to JS and consumed by Javascript? IOW a Javascript app which has a dependency on a kotlin lib? getting hung up on importing the kotlin compiled js. Sorry, JS newb here

Anyone interested in helping with a Kotlin MP Redux? Goal is a version of redux that supports all platforms. Specifically looking for someone with some JS expertise to help with consuming shared Kotlin code from actual JS code. Starting point would be the counter sample app. https://reduxkotlin.org

Do tests still need to be ran with something like this: https://stackoverflow.com/questions/52618371/how-to-make-my-js-tests-appear-in-kotlin-multiplatform-project

In kotlinx , do I need to write serialization strategy for each List<CustomClass> inside other class?

hi guys , how I do include a custom css file using require? so far I have tried using

require("css/normalize.css")

and

require("./css/normalize.css")

but i'm getting : Module not found: Error: Can't resolve 'css/normalize.css' in '/home/devquilla/repository/ServerCPSVertx/WalletCPS/dashboard/build/kotlin-js-min/main' @ ./dashboard.js 2777:4-32

Hello, I am trying to start a new project using experimental frontend plugin provided by Kotlin 1.3.50 I am able to write code without any errors, and having code completion. When I am running the code, I am getting this kind of error:

ERROR in ./kotlin/sample1.js
Module not found: Error: Can't resolve 'kotlin-react' in '/Users/user/IdeaProjects/project/build/js/packages/project/kotlin'
 @ ./kotlin/project.js 3:4-97
 @ multi ./kotlin/project.js source-map-support/browser-source-map-support.js

I guess this not integrated in my bundle. How can I do so?

Hi! We are designing how Kotlin code will be visible from JavaScript in the new version of Kotlin/JS. I'd like to gather some data. To what extent do you use Kotlin code from JavaScript? 0️⃣ - Kotlin code calls JavaScript, but not vice versa. 1️⃣ - JavaScript calls a few Kotlin functions or uses a couple simple classes. 2️⃣ - JavaScript code uses a substantial portion of Kotlin library API. Thanks!

Sure you just need to run a JS engine with something like graal or the now-deprecated nashorn or by calling out to V8, QuickJS, Duktape, etc.

Maybe the way webjars packages their stuff?

in tests wie love to use

long sententces with blanks as test names

. As this is not valid in javascript wie use

@JsName("testN")

annotations. but this still tedious. is there a way to autogenerate the js functionname for test functions?

I need some help learning webpack for kotlin multiplatform 1.3.50. I see that there can be a webpack.config.d directory that appends configuration to a generated webpack config file, but I can't find any documentation for the syntax of the js files it's expecting. I'd like to be able minify / combine all js dependencies for a production build, but not have the extra processing for dev builds.

Is it safe to call

RComponent.setState

(from the Kotlin react wrappers) from a coroutine? I haven't seen any examples of react/coroutine integration.

Anyone can say how I can describe in jsruntime property that is function in my external interface?

Hmmm, does the MPP webpack task not install transitive NPM dependencies of Kotlin modules correctly? For example, even with

implementation("org.jetbrains:kotlin-react:16.9.0-pre.83-kotlin-1.3.50")

I'm getting

Module not found: Error: Can't resolve 'react'

Nevermind, this is because for whatever reason the wrappers don't declare their dependencies: https://www.npmjs.com/package/@jetbrains/kotlin-react

Opinions, improvements?

class JsonObject {
    val obj = js("({})")

    infix fun <T : Any> String.l(other: T) {
        obj[this] = other
    }
}

fun jo(builder: JsonObject.() -> Unit): Any {
    return JsonObject().apply(builder).obj as Any
}

fun main() {
    val test = jo {
        "this" l "that"
        "this other" l 1
        "user" l jo {
            "first_name" l "jane"
            "last_name" l "doe"
        }
    }
}

Is it possible to overload

functionProperty

? If so how?

external interface SomeInterface {
    var functionProperty: (param1: Type, param2: OtherType) -> ReturnValue
    var functionProperty: (param1: Type) -> ReturnValue
    var functionProperty: () -> ReturnValue
}

New to writing Kotlin wrappers, what is the correct way to wrap an object that consumes another object (i.e.

Foo({...})

)?

I am wrapping jQuery library and Dukat gives me following definition:

external interface JQuery {
    fun fancytree(options: FancytreeOptions = definedExternally /* null */): Fancytree
    fun fancytree(option: String? = definedExternally /* null */, vararg rest: Any): Any
}

It is obvious that I can't use it with kotlin jquery since this JQuery and jQuery in the bindings are two different things. How can I make it right?

hi there any chance to get 2 output files from kotlinjs(new plugin 1.3.50) project (working on chrome extension and need 2 files with main() functions)

Is there any way to associate multiple

requires

with a single wrapper file? For example, the

swagger-ui

, which is bundled with

swagger-ui/dist/swagger.css

. The CSS should always be required whenever the

swagger-ui

export is required. AFAIK you can only have a single

@file:JsModule(...)

annotation.

Just confirming here, based on what I've seen in several threads, there is currently no type-safe way to support Union Types in KotlinJS? I'm fine with just returning

dynamic

, but just wanted to confirm.

Hey! The latest Idea EAP build still produces non working (out-of-the-box) gradle Kotlin/JS + Kotlin/JVM projects ... is there a simple fix?
