[Solved] How can instance an object of type dynamic without

js()

function? Code:

external fun require(module: String): dynamic
fun App() { 
  val Koa        = require("koa")
  val app        = Koa() //Dont work: Generate Koa() in JS script need new Koa() 
  val app        = js("new Koa()") // GOOD
}

Generate this:

var Koa = require('koa');
var app = Koa(); //BAD: i need new Koa() in JS script

Hey everyone, I wanted to use MSAL in Kotlin/JS with Dukat but I'm getting a "External type extends non-external type" on this class:

external open class ClientAuthError(errorCode: String, errorMessage: String = definedExternally) : AuthError {

AuthError itself is:

typealias AuthError = Error

Error is Kotlin's stdlib Error What can I do to fix that?

Are enums accesible from js (are they exported?)?

Anybody have idea how to publish the end result of compilation to npm?

How are function types mapped to js? is

() -> Unit

compatible to be exported?

Can we have a decompiler for Kotlin -> JS, just like Kotlin -> Java? 👀

interestingly

Promise<Unit>

is unexportable 👀 should use

Promise<dynamic>

? is there something like java.lang.Void or something for js?

Its just

@Test

annotation of

kotlin.test

package

Did I declared the module wrong?

If I install kotlin together with kotlinx-coroutines-core via NPM There are dependency conflicts, but if I remove kotlin package in my package.json resolve conflicts and finds the kotlin and coroutines modules. Does kotlinx-coroutines-core include the Kotlin package in NPM?

"dependencies": {
 "kotlin": "^1.4.0",  // Conflict with kotlinx-coroutines-core package
 "kotlinx-coroutines-core": "^1.4.2",
},

has anyone tried kotlin with vue?

Hello everyone, anyone having problem with js build location with kotlin multiplatform project? I have KMP that has following `build.gradle.kts`in

commonMain

for the

js

target

js(LEGACY) {
    browser {
        binaries.executable()
        webpackTask {
            cssSupport.enabled = true
        }
    }
}

and if I run the `jsBrowserDevelopmentRun`task (in project root) the started webpack-dev-server serves from

<project-root>/mainModule/build/processedResources/js/main/

path, but the actual build is located at

<project-root>/build/js/packages/<project-name>-mainModule/kotlin-dce-dev/<project-name>-mainModule.js

how can I get to the build fil in my

index.html

then (located in

<project-root>/mainModule/src/jsMain/resources/index.html

)? Even if I hardcode relative path to the build file, the dev server won't serve it (I guess it's forbidden to go up from serve path - for security reasons - by default).

Hi! It's my first time trying to compile a Kotlin Js library (3rd party), and the build keeps on getting stuck at kotlinNpmInstall... I tried googling and saw that some set the npm registry or empty the cache, tried that, but still getting stuck... did anyone encounter this before?

I can’t seem to find any examples doing multipart form upload (for uploading images). has anyone accomplished doing javascript multipart upload using ktor?

Hello, I'm trying to use Microsoft Graph types (https://www.npmjs.com/package/@microsoft/microsoft-graph-types) with generateExternals = true. The problem is that microsoft graph types has a List type of its own that "shadows" kotlin.collections.List as what's generated seems to be in the "root package". Isn't there a way to put the types generated for that library in a separate package automatically?

How to define external declaration of a static function?

Hello. I am writing a multiplatform library which will be used by desktop and web applications also. I want to use Kotlin JS with electron or something similar and I want to access Filesystem apis via Node js exclusively for desktop version. So right now I am trying to find a way to achive this. I am thinking of 2 ways but dont know what to do technically. First one is to use directly electron and its nodeIntegration feature but I couldn't use node apis via Kotlin. (Tried to run in electron window but getting 'fs' not found error and I don't have an idea how to configure Webpack) Second one is to render the application in a local server and show it in electron but I dont know is it technically possible with Kotlin or not What you guys recommend me to do?

Hi everyone I am writing a Kotlin/JS library and want to enable the IR compiler backed. In gradle it would be

kotlin{ js(BOTH) }}

, however I am using Maven. Does anyone know how to do this in Maven and pom.xml?

Is there some trick to get sourcemaps working with kotlin js and the multiplatform plugin? I set sourceMaps to true in the browser runTask, source map files get generated but I see no sign of the browser doing anything with them. Also the .map files seem unavailable via the dev server (I get a 404 when I request them). What am I missing? I'm using the fritz2 framework.

Newbie to the JS and multiplatform system here. I would like to ask you how usable is the new JS backend introduced in v1.4. My case is this: we have a multiplatform library that we would like to use on the JVM and inside web applications written in TypeScript. It is not clear to me if it is better to use the old JS backend or the new one, and it is difficult for me to assess how much trouble I will get in using the Kotlin library from TS code. Could you share your experience, please?

Hey Kotlin JS Community! I am new to Kotlin/JS and I would like to ask can I develop an SPA entirely in Kotlin/JS (preferably kotlin-react) ? (Note: I have very little knowledge in react) Also any impact on performance? Suggest me any resources to get started with kotlin/js Thanks in advance.

Ok seems it was picked after clean build into the jar, but this doesn't seem to work

public external fun require(module: String): dynamic
val something = require("./<some non constant value>")

It says

Error: Cannot find module './<...>'

Hmm, seems like tests run on

<root_dir>/build/js

where the resources are not copied, is it intended behavior??

Hey, I wanted to get into KotlinJS today but I can not seem to get it working. I tried every template in the setup dialogue for a new project and even download the code from try.kotlin.

Do singletons have JS interop, how do you access the instance blob thinking upside down?

Is there a way to rename the exported module, or make them top level?

Is there a way to stop mangling names for a class/interface?

How can I get free Javascript logo stickers?

Is this a bug? Why's the function declared twice?
