A modern programming language that makes developers happier.

kotlinlang

How are we supposed to use an NPM dependency using the kotlinjs plugin ? Are we supposed to import it in the html or will it be somehow automagically bundled in one big js ?

It is bundled in one big js via webpack in new `js` plugin
You need to add only it to `index.html`

Ok that's what I thought. Any idea what I am doing wrong in <https://github.com/jdemeulenaere/kotlin-pixijs> ? I am just trying to get started and make the "Setting up" section of <https://github.com/kittykatattack/learningPixi#setting-up> work :slightly_smiling_face: I tried to use dukat to generate the external definitions but it has a lot of failures during compilation (and I don't mind writing the external definitions by myself first). Thanks!

Error in the console: `Uncaught ReferenceError: sayHello is not defined`

I think, that problem is in `external` declarations, you can just see what dukat generate to you, especially pay attention on the first annotations `@JsModule` and `@JsQualifier` (<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.js/-js-module/index.html> and <https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.js/-js-qualifier/index.html>)
I think it should be something like
```@file:JsModule("PIXI")
@file:JsQualifier("utils")
package PIXI.utils

external fun sayHello(type: String)```

If I add those annotations then I get another kind of error: `When accessing module declarations from UMD, they must be marked by both @JsModule and @JsNonModule`

It is because there is `UMD` module system for Kotlin/JS by default which includes plain non modular js
You can add `useCommonJs` in `target{}` block
Or try to add `@file:JsNonModule` to external declaration file

useCommonJs fixed the problem :slightly_smiling_face: Thanks!
