kotlinlang #javascript

Known problem? I construct message objects for a messaging system with builder constructs. I first build an update, then use this update in a payload builder to send off over http. When this is compiled to JS, the same variable name is used over, which is fine by me, but since I use builders that return self (this) in a lot of functions, the variable changes contents before use, resulting in a classcast exception. I will post an example in a thread here.

Is it possible to create .kts files with JavaScript as the target?

I have a problem trying to call sockjs-client (https://github.com/sockjs/sockjs-client) from my kotlin code - I have used @file:JsModule("sockjs-client") and @JsName("SockJS") to define an external class / function for SockJS. But I either get Uncaught TypeError: SockJS is not a constructor or Uncaught TypeError: SockJS is not a function 🤔 (also I am not really good with javascript 😄 )

How can I access `kotlin-react-redux`'s functions? Each

moduleKind

configuration in Gradle gives me a different error: -

default moduleKind

or `moduleKind="umd"`: " When accessing module declarations from UMD, they must be marked by both @JsModule and @JsNonModule " - `moduleKind="plain"`: " Can't access function 'createStore' marked with @JsModule annotation from non-modular project " -

moduleKind="commonjs"

compiles the

main

sources fine, but then I get the following for tests:

When accessing module declarations from UMD, they must be marked by both @JsModule and @JsNonModule

Did I miss something? Am I required to define a

moduleKind

separately for tests? Where is it then?

Without the interface, I get the string property as "string". Anyway around this or do I just have to nix the interface?

Am I the only one with compile logs filled with

I am creating a

object {}

with any number of properties and functions that will be processed in a given way. I would like to mark the properties to make logical decisions about them in the processor. If I understand correctly, js annotations are not possible. Is there another way? What I need specifically is I need properties of the object to exist in the definition but not the final product. Potentially I could have

val prop1: String = "value"  and val prop2: String = "value2"

and I would like to include

prop1

but not

prop2

Is there anyway to get the

org.jetbrains.kotlin.js

gradle plugin to run

ts2kt

automatically? Does it do this already?

Hey, I've got a question about the kotlin stdlib generated. I'm using the DCE tool to trim it down, however, this "new" stdlib is still using the basic

Kotlin

variable name. In my environment, I'd like to be able to use different versions of the stdlib, each containing the specific code it uses. To do this, I need to be able to control what the

Kotlin

variable is actually called. Is this possible?

how do i use the gradle frontend plugin nowadays? https://github.com/Kotlin/kotlin-frontend-plugin/blob/master/README.md looks a bit outdated and indeed, i am unable to use this plugin with kotlin 1.3.41 (

Cannot add task 'processResources' as a task with that name already exists.

). Or maybe it's gotten deprecated and i do not need it anymore?

when using the 1.3.41 js plugin, is there a way to pass a configu variable to the webpack process?

Hi friends! In Kotlin 1.3.30, I had a setup as follows: -

libA

was a MPP that depended on

stdlib

using

implementation

libB

was a MPP which depended on

libA

and

stdlib

using

implementation

libC

was a Kotlin/JS project, depending on

libA

libB

, and

stdlib

using compile
I was able to build

libC

with

kotlin-dce-js

. I got a version of

stdlib

that contained the overlap that was used by all three libraries. I could also use

runDceKotlinJs.keep

to expose specific methods from

libA

libB

and

libC

to be called from pure JS. After bumping to Kotlin 1.3.41 however (still using

kotlin2js

plugin), when I try to run

:libC:runDceKotlinJs

, I get error messages complaining that

error: duplicate target file will be created for '/opt/projects/my-repo/libA/build/libs/libA-js-0.1.4.jar!lib/kotlin.js' and '/Users/amgupt01/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-js/1.3.41/55b92e441b0ea9cbf079c6452b41687f95571524/kotlin-stdlib-js-1.3.41.jar!kotlin.js'

Any ideas? EDIT: I've tried using the newer

org.jetbrains.kotlin.js

plugin, as well as changing `libC`'s dependencies to be

implementation

instead of

compile

. Still no luck 😕

Super excited about Dukat guys. ts2kt had several errors on every single library I tried to convert, and if you guys are confident enough in it’s replacement that it will automatically convert ts libs to external declarations and import them, that sounds fantastic. This is exactly the kind of thing that kotlin-js needs to reduce headache and drive adoption.

If I add coroutines to my project the resulting bundle is too big and webpack issues a warning in the JS console, even if I add the DCE plugin. Not sure what webpack configuration I need to fix that. Any suggestions?

Hey guys! I tried to upgrade my project to Kotlin 1.3.50 and the following development server configuration doesn’t seem to work anymore. Any hint where I can find the correct DSL for it?

webpackTask {
                runTask {
                    //todo: use dsl after KT-32016 will be fixed
                    devServer = new org.jetbrains.kotlin.gradle.targets.js.webpack.KotlinWebpackConfigWriter.DevServer(
                            true, false, true, true, false,
                            8081,
                            ["/api": "<http://0.0.0.0:8082>"],
                            ["$projectDir/src/main/resources".toString()]
                    )
                }
            }

Is anyone using the new built-in JS test runner that shipped with Kotlin 1.3.40+? I'm struggling to figure out how to get it to get it to give me JUnit-style XML test reports (which are CI-friendly), rather than only the HTML report.

Anyone have any pointers for writing a Gradle Plugin that finds methods or fields annotated with

@JsName

and automatically adds them to

runDceKotlinJs.keep

? Keeping DCE Keep and JsName declarations in sync seems to be a consistent annoyance for me, but doesn't seem to be getting much love from Jetbrains... would love to be able to write it myself, but I'm a little lost on figuring it out.

I’m assuming that

generateExternals

is the task that calls Dukat and generates code for the TypeScript definitions? I’m having problems debugging it. The task completes successfully, but no code is generated for the NPM package I’ve included (lit-element).

This is a bug. There is

"typings": "lit-element.d.ts"

lit-element/package.json

, but currently we are searching for

types

key only. According to https://www.typescriptlang.org/docs/handbook/declaration-files/publishing.html,

typings

should be supported too. ~~Please fill an issue in youtrack~~
