Hello :wave: Beginner question : What should I do ...

# javascript

Hello 👋
Beginner question : What should I do to get the @JsModule Annotation to work. I have applied the kotlin multi-platform plugin and configured kotlin { js(IR) { nodejs() } } . Currently IDE(IDEA) says unresolved reference.

What are you trying to do?

[Dinesh R]

I want to use a node module in my kotlin code.

[Dinesh R]

something like this

@JsModule("my-module")
external fun myModule(): String

Check out https://kotlinlang.org/docs/using-packages-from-npm.html as a starting point. It's pretty concise documentation so read carefully 🙂

Here is an example for Sortable.js - but be warned, there's a lot of variation in how you approach this based on the library.

@file:JsModule("sortablejs")
@file:JsNonModule
package rcp.libs

import org.w3c.dom.Element

@JsName("default")
external object Sortable {
    fun create(el: Element, options: SortableOptions)
}

One thing that can be useful: after running gradle to import it, look in build/js/node_modules at the structure of the library you're working with.
