Trying to deserialize a polymorphic type.

"Any type is not supported"

Got a newb question for folks. The JS websocket definitions require an ArrayBuffer --- but I have code that hands me a ByteArray — There should be a way to convert them.. under the hood are they the same thing?

I mean, what I would like to do, is call JS code - which would be executed in node - and get results from it into the kotlin app (which will be running on JVM). Is that possible?

can i somehow run webpack in two different configurations in a single module with the frontend plugin? (filed: https://github.com/Kotlin/kotlin-frontend-plugin/issues/83)

is there an easy way to reconcile the fact that some APIs are available globally in the browser but require

require

in node? For example, I want to test code that uses

URL

. Nevermind I'm an idiot and used a reeeeally old version of node.

hello! when kotlin-js-wrappers libs on https://dl.bintray.com/kotlin/kotlin-js-wrappers will be updated to 1.2.51? when using kotlinx-serialization kotlin 1.2.51 is recomended, but kotlin-js-wrappers for 1.2.51 doesn't exist. for example, last version kotlin-react-dom - 16.4.1-pre.34-kotlin-1.2.50 Updated Jul 06.

Because when I use "plain" in compileKotlin2Js then nothing is accessible from JS. I need JS filed generated that can be used from JS without modules required.

Hi everyone! Did anyone manage to successfully get external type definitions for Firebase using ts2kt? I’m getting a partial output with several errors.

Sadly I get the same error with

@JsNonModule

Has anyone had any success getting Kotlin to work with React Native?

Am I crazy or is geolocation not mocked in Kotlin.js?

But still I am having:

main.bundle.js:1 Uncaught (in promise) ReferenceError: JSONFormatter is not defined
    at P (main.bundle.js:1)
    at b (main.bundle.js:1)

Hey all, do you use any web frameworks with Kotlin? I have been developing my own with the idea of having abstracted ViewControllers, Routing, etc in a multi-platform way. Basically Everything is cross-platform except for the views. Would anyone be interested in this? I didn't originally plan on open sourcing it since I figured it would be to custom tailored to my own requirements. Also I figured most ppl use either React or Angular, which I am not a fan of and my approach might be to much like an iOS/Android app for web developers.

I am exactly in the same situation, currently all business logic in kotlin and all views in VueJs; but it is a pain to recreate Kotlin object into typesciprt ones: I did not try this project yet though: https://github.com/ntrrgc/ts-generator

@dany thats the same one I am looking at as well! If one could integrate it into the build process so the models are always up to date and when I makes changes in the backend the typescript vue code stops working would be fantastic

Yea I don't mind concating them, but it won't export the library file unless I use DCE.

Oddly enough dceOptions.devMode doesn't seem to work anymore

Another potentially silly question. I've got a JS project that defines its "enums" as hardcoded string constants in a big array. I've also got a Kotlin multiplatform project where I redefine those string constants as real `enum class`es and have some methods/classes that take them as inputs and use them as properties. I'm trying to interact with the Kotlin/JS output from the older JS project. I'd like the older JS project to be able to treat the enums as regular string literals when calling those methods accessing them as properties of other classes. Is there a standard way to do this? Here's a gist with a barebones example of what I'm talking about and some more details (including what I've tried and what else I think I can do): https://gist.github.com/ankushg/069c743f7fe40e71afbe67632d98b7bc

Hello everyone. Im creating a library with wrappers for redux and react/redux, One of the problems I have is that when I build the library for distribution, all the comments are gone. Any ideas on how to tell the compiler to keep the comments? maybe in the .kjsm file? Thanks!

Hi everyone. I found a weird compiler behavior. Here is the row:

attrs.caption = state.toBeDeleted?.asDynamic()["name"].toString()

I'm expecting that if

state.toBeDeleted

is

null

, the rest of row will not be invoked, and

null

will be the value of the whole expression. But this row is compiled into:

$receiver.attrs.caption = ((tmp$ = this$Content.state.toBeDeleted) != null ? tmp$ : null)['name'].toString();

And the result is

Cannot read property 'name' of null

. Am I misunderstanding something?

i have 4 modules with the frontend plugin and npm install is just killing me in terms of build time. 99% of the modules that each one are installing are the same. apparently node has a mechanism for concurrent locking during install, but there doesn't seem to be a way to pass

-g

for the install task. I would also just love to see project.buildDir changed to rootProject.buildDir (if the locking works). But global would be preferred for CI so that I could share the global installs across runs (similar to how Gradle stuff is in ~/.gradle)

Is there somewhere I can go to see what's on the roadmap for Kotlin.JS?

Is there a way to change the name of the JS module generated by Kotlin? For example, if I'd like to prefix it with a scope (https://docs.npmjs.com/misc/scope)?

Is it possible to set the module name for a Kotlin JS lib (a Kotlin Platform module) via Gradle Kotlin DSL?

Hi, do you have simpliest example? I want to do library. For instance with kotlin frontend plugin. And I want to include bundle in js or typesript project and use it there

Hi. I've read in several sources that kotlin2js compilation has ES6 modules in a roadmap. Does anybody know how far is it?

I'm trying to link with an external JS library using ts2kt. Typescript definition has a class with constructor. Constructor has an argument of type

Config

. There is also

declare type Config = { ... }

. In kotlin code

Config

becomes an external interface with plenty of optional vars. How should I create an instance of this interface? Just like this?

val cfg = object : Config {
    override var width: dynamic
        get() = 200
        set(value) {}
    override var height: dynamic
        get() = 300
        set(value) {}
    ...
}

It looks monstrous for me...

So, maybe I am asking wrong way. I want to do node js library. Which was originaly kotlinjs. And it is bundled. This library should have some js file, package.json and index.d.ts. So I did example project.

compileKotlin2Js {
    kotlinOptions.outputFile = "${projectDir}/build/web/output.js"
    kotlinOptions.moduleKind = "commonjs"
    kotlinOptions.sourceMap = true
}

which is like:

(function (_, Kotlin) {
  'use strict';
  var println = Kotlin.kotlin.io.println_s8jyv4$;
  var Kind_OBJECT = Kotlin.Kind.OBJECT;
  var Kind_CLASS = Kotlin.Kind.CLASS;
  function Example() {
    Example$Companion_getInstance();
    println('Example constructor');
  }
  Example.prototype.exampleMethod = function () {
    println('Example method');
  };
  function Example$Companion() {
    Example$Companion_instance = this;
  }
  Example$Companion.prototype.exampleStaticMethod = function () {
    println('Example static method');
  };
  Example$Companion.$metadata$ = {
    kind: Kind_OBJECT,
    simpleName: 'Companion',
    interfaces: []
  };
  var Example$Companion_instance = null;
  function Example$Companion_getInstance() {
    if (Example$Companion_instance === null) {
      new Example$Companion();
    }
    return Example$Companion_instance;
  }
  Example.$metadata$ = {
    kind: Kind_CLASS,
    simpleName: 'Example',
    interfaces: []
  };
  Object.defineProperty(Example, 'Companion', {
    get: Example$Companion_getInstance
  });
  var package$net = <http://_.net|_.net> || (<http://_.net|_.net> = {});
  var package$aliceintokyo = package$net.aliceintokyo || (package$net.aliceintokyo = {});
  package$aliceintokyo.Example = Example;
  Kotlin.defineModule('output', _);
  return _;
}(module.exports, require('kotlin')));

//# sourceMappingURL=output.js.map

So now I want it to use in node js project. When I created simple nodeje module, installed it and I called

var simple = require("simple");
console.log(simple)

I got printed:

[object Module]

When I did same with example, I got no error, but:

[object Object]

What am I doing wrong? How to require compiled kotlinjs?

Are there any benchmarks of Kotlin-js? I'm interested to see how kotlin/native performs against hand written js
