List doesn't have Companion object. What is original Kotlin code?

is there a way to use

console.table

in kotlin.js?

Hey everyone, is there a way to get method docs and autocomplete for node_modules already installed, in KotlinJS module?

Can I primarily write in Kotlin while working on react and node.js projects? I know Kotlin can compile straight to JS but my coworker would still use JS only.

I'm pretty inexperienced with JS and I'm trying to set the width of an element with

element.style.setProperty("width", "$value")

. Am I doing something wrong?

I want to try some kotlin for the browser, would https://github.com/JetBrains/create-react-kotlin-app be a good starting point? Basically I want to interact with a GraphQL endpoint, and make something comparable to what I now have with clojurescript using re-frame (which uses react). I also saw somebody suggest https://github.com/rjaros/kvision but on first look it looks very verbose.

In the case, if you would like to help to review declarations for Firebase welcome to the PR! https://github.com/Kotlin/js-externals/pull/22

How can we user navigator.mediaDevices.getUserMedia

Are you using any npm dependencies

Hi guys. Is there any good way to use Vue/Vuex with Kotlin?

Noob question, how to get Gradle to output kotlin.js? EDIT - Don't worry, found a workaround for needing to do this

Hi, I've a strange error, If I had this code to my existing Kotlin code :

doc.data()!!.get("label").toString()

(get data from firebase firestore) Compiler add these lines (with others but seem good for me) :

// After use strict
var $$importsForInline$$ = _.$$importsForInline$$ || (_.$$importsForInline$$ = {});
// At the end
$$importsForInline$$.index = _;

When I try to start the node, I got an error message

Maximum call stack size exceeded

If I remove these 2 lines, it works perfectly. I don't see why I got these lines, can you help me ?

hello! somebody use kotlin-react?

You may find Redux’s boilerplate to be a little offputting as well if you’re coming from reframe. React 16.3's new Context API is probably where you should start for state management if local component state isn’t sufficient. The Context API is simple and easy to use and is what powers things like Redux.

I’m having some problems with a multi module project and kotlin2js. My main module depends on my other module using

compile project(":common")

which results in the output JS file having

require('common')

in it which of fails in runtime since there is no module named

common

. Can I somehow make it either inline the library code or require a path instead?

I don’t say that this is never be implemented (union types is better solution than

dynamic

), but for now I think it’s too big feature that cannot be easily supported on jvm

is it possible that tailrec functions in JS are not optimised? I just got a Maxium call stack size exceeded

At my work we are considering using Kotlin as the language for creating front ends to our products. For my work to embrace Kotlin fully it's critial that it will be usable with some popular framework or library. As I experience, JetBrains have already made some support for using React: https://github.com/JetBrains/kotlin-wrappers/tree/master/kotlin-react https://github.com/JetBrains/create-react-kotlin-app I've also seen the kotlin-frontend-plugin: https://github.com/Kotlin/kotlin-frontend-plugin. Does anyone have any guideance on which road to take? Should I use the create-react-kotlin-app or would it possible to use kotlin-frontend-plugin to setup a similar react project like the create-react-kolin-app do? I'm coming from the Java sphere, so personally I would like it to be possible to develop with the kotlin-frontend-plugin. However the kotlin-frontend-plugin seems a bit unfinished? and low prioritized? Does any one have experience or knowledge to share that could help me in choosing a development environment for using Kotlin and React? @Leonid Khachaturov @cy Thanks!

CRKA is mostly targeted at people with some frontend background willing to try Kotlin. So it's probably not your case

Is there any guidance on creating a multi-platform Kotlin library (JVM and JS) so that Javascript developers can easily interface with it while programming in pure Javascript? I noticed that KotlinJS generates a lot of ugly Suffixes on functions like

create_puj7f4$

even though there is only one

create

function and since

@JsName

is not available in a platform-common project, I am not sure what I can do to prevent that.

Hi! Can anybody help me? Nobody answer me in #multiplatform

Ok, I have a kotlin to javascript conversion question. Lets say I am using an external javascript library which rebinds 'this' on a callback that you pass in. How do I construct a lambda in kotlin that can simulate this behavior?

Yesterday I found out that you can use react with Kotlin (https://github.com/JetBrains/create-react-kotlin-app). Should I actually learn react separately first with JS or can I jump straight into Kotlin without knowing fundamentals of react?

Is there any annotations to cast

this

as another class? Now I'm writing

fun (){
    val component = js("this") as VueComponent
    component.doSmth()
}

I want

@JsChangeThis(VueComponent)
fun (){
    this.doSmth()
}

Does anybody has already tried to load Google maps and call its API from a kotlin/JS module?

I use KotlinJS with Maven. JS-files packaged in war-file. Is there any possibility to organize automatic recompilation and debugging when war is running (via war:run-war or jetty:run)? Such behaviour realized for GWT configuration - https://www.jetbrains.com/help/idea/run-debug-configuration-gwt.html. Test project - https://github.com/turansky/kotlinjs-hot-run

Hi, I'm trying kotlin react. I mixed successfully the usage of

kotlin-frontend-plugin

and the sample from

kotlinconf-app

(https://github.com/JetBrains/kotlinconf-app). Now I would like to add

ukit

, so I added it to the

npm

part of the buildscript. But I dont know/understand how to bundle it or make it served by webpack. (Given I'm a total newbie with webpack and last time I touched web development, HTML 3.2 was still the state of the art)
