Hi guys, I have a javascript module with source and tests directories. I use the AMD module kind. I just saw that both source and tests are exported using the same module name. That seems to be the cause of some problems (test functions are not defined when loading together source script and test script). Can that be possible?

Why does kotlin2js require

main

to take an array of strings for it to be detected but then the generate code passes an empty array?

fun main()

is not used as entry point,

fun main(args : Array<String>)

is used as entry point but

args

will always be an empty array. I'm using

moduleKind = "commonjs"

.

@konsoletyper @bashor I created bug https://youtrack.jetbrains.com/issue/KT-16979 There is an enclosed mini project.

For my project, I tried to port code from kotlintest. Is there a way to test the type of an instance which works for both my classes and Primitive types:

class A

    fun allTests(){
        println("${1 is Int}") //true
        println("${A() is A}") //true
        println("${A::class.isInstance(A())}") //true
        println("${Int::class.isInstance(1)}") // Uncaught TypeError: Cannot read property '$metadata$' of undefined
    }

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?

Hi, thanks for helping @melatonina, but what exactly is meant with that "platform autodetection by stdlib dependency"? I modified the code a little bit without that and it works just fine. https://github.com/wojta/kotlin-nodejs-experiment

anyone got any experience using kotlin with react?

How do kotlin-js stacktraces work?

are there any examples of calling a kotlin-js library from javascript?

ah, figured it out. In the documentation for kotlin it shows adding a callback to the requirejs call, if I remove that it works fine

📣 📣 After JS got non-experimental with Kotlin 1.1 we are starting to slowly deliver on tooling around it. Hereby we want to show some of the early work on Gradle/NPM/WebPack for those who has multiplatform project (backend + frontend) and want to use Kotlin throughout the project, have a single project structure and still enjoy NPM as a repository for JS libs, webpack devmode and all the rest. Check out https://github.com/Kotlin/kotlin-frontend-plugin and tell us what do you think!

some neither beer nor wine 😉

@Tristan Caron give a look at this: https://github.com/danfma/kodando-react-sample.

@sdeleuze amen. Would it be possible to provide at least the kotlin stdlib as webassembly? Might at least solve one of the complaints that have been expressed regarding kotlinjs

I don't want to be an asshole, but any time estimations? In the next hours? In the next days? Weeks? Months? Thanks for an open communication 🙂

Since they're sharing memory I will call them threads :)

has anyone used d3.js with kotlin here?

Generation was clean. But I'm struggling with trying to use it from kt source

@konsoletyper you may be interested in this https://github.com/angular/tsickle/blob/master/README.md

With JS backend the result is

false

, with JVM backend it is

true

Is it possible to compile Kotlin to Typescript?

Hi guys, I'm playing with https://github.com/Kotlin/kotlin-fullstack-sample and I was wondering if there is a way of sharing the model files between backend and frontend

How can I minify kotlin-js and still have relevant source maps?

how easy is debugging kotlin javascript in the browser? I have some js extension type code I'm thinking to port to kotlin because 1. it would be nice 2. I hate javascript . But I also don't want to make my life more complicated

Did anybody tried to use closure to remove unused code (including kotlin.js)?

Hi. I would like to convert an Int to an hex string. I found the

String.toInt(radix:Int)

but didn’t find the opposite.

so the div { span { ... } } is missing from the document fragment, but they should be there

Has anyone managed to get the full-stack example (https://github.com/Kotlin/kotlin-fullstack-sample) building on Windows? I get:

:frontend:webpack-config UP-TO-DATE
:frontend:webpack-bundle
module.js:472
    throw err;
    ^

gradlew build

or

Is there a way to tree-shake the generated webpack? It's pretty large because of the kotlin library that comes with it.

uglify is unable to minify it good enough, there will be a tool to do that (not yet ready right now)
