for that specifically, `val root = js { message = ...

# javascript

for that specifically, val root = js { message = { "Hello World!!" } } ? (import kotlinext.js.js)

[Roman Artemev [JB]]

Could you please explain how it doesn't work? Are you getting a compile error?

[Marcel Overdijk]

@araqnid thx for your response, should I include another lib in my gradle build file for that import? kotlin-js does not seem to include this)

[araqnid]

it’s from https://github.com/JetBrains/kotlin-wrappers/tree/master/kotlin-extensions

[araqnid]

which I’m getting through npm at the moment

[araqnid]

although it’s just a convenience wrapper: you can get a fresh object by calling js("{}") and then just set arbitrary properties on it (as it is type dynamic)

[Marcel Overdijk]

OK, I tried that by adding

"dependencies": {
    "@jetbrains/kotlin-extensions": "^1.0.1-pre.28",

to package.json via npm install -i

[Marcel Overdijk]

However when building I still get a Main.kt: (3, 8): Unresolved reference: kotlinext

[Marcel Overdijk]

Note the page you mentiond also sya to run npm run gen-idea-libs but that gives me:

$ npm run gen-idea-libs
npm ERR! missing script: gen-idea-libs

[Marcel Overdijk]

the js("{}") variant works btw

[araqnid]

ah, I’m using a template based on create-react-kotlin-app, this is part of the myserious build system it creates, I guess

[araqnid]

afaik gen-idea-libs is a help to auto-generate the .idea/libraries/*.xml files, so it’s just automatically some of the manual project structure setup (which tbh I’m wholly unfamiliar with, as intellij projects are usually just imported from Gradle for me)

[araqnid]

but that config file it built is just a library config of type “kotlin.js” referencing file://$PROJECT_DIR$/node_modules/@jetbrains/kotlin-extensions/build/classes/main

[araqnid]

for Gradle, it seems the recipe is:

repositories {
    maven {
        url  "<https://dl.bintray.com/kotlin/kotlin-js-wrappers>"
    }
}

dependencies {
    compile 'org.jetbrains:kotlin-extensions:1.0.1-pre.28-kotlin-1.2.30'
}

[araqnid]

with that, I was able to use the library in a stripped-down app without CRKA

[araqnid]

well, I was able to get it linked in the IDE; seems it needs “core-js” at runtime

[araqnid]

btw @jetbrains/gen-idea-libs is an npm package too, maybe just adding that would let you run it

[araqnid]

although in fact react-kotlin-scripts is inserting some extra fun “dynamically find the Kotlin/JS libraries inside node_modules” stuff before actually calling it

[Marcel Overdijk]

thx a lot for you patience! I gonna try your suggestions

[Marcel Overdijk]

Yes, adding compile("org.jetbrains:kotlin-extensions:1.0.1-pre.28-kotlin-1.2.30") works! thx again!
