Hi everyone! I have a question about kotlin.js vs kotlin.multiplatform

The recommended way to use Kotlin/JS is via the kotlin.multiplatform Gradle plugin. This is said by the doc Kotlin for JavaScript.

A year ago it was:

The recommended way to use Kotlin/JS is via the ``kotlin.js`` and ``kotlin.multiplatform`` Gradle plugins.

Bot, and not just kotlin.multiplatform.

Does it mean that kotlin.js will be deprecated and the main approach will be only kotlin.multiplatform?

If I want just JS target should I prefer still use kotlin.multiplatform? If I want only JS target, for example write a GitHub Action in Kotlin.

[CLOVIS]

Yes, always use kotlin.multiplatform .

Recently, I’ve tried to build a GitHub Action using KotlinJS, but I found it a bit tricky even with kotlin.js. Now, I should use Kotlin Multiplatform and source sets, which adds a little bit more headaches :)

[CLOVIS]

Apart from the different directory names (src/main → src/jsMain) and some gradle tasks having js at the start, you shouldn't see any differences

[Max Kachinkin]

I guess you’re right.

[CLOVIS]

There is actually only one Kotlin plugin. If you notice, all kotlin.* plugins point to the same JAR. The only difference between them is some initialization logic (task names, folder names…) but they all behave exactly the same

all kotlin.* plugins point to the same JAR

I didn’t know that. Cool then.

BTW there are already some existing kotlin frameworks for GitHub Actions, eg the one from Ryan https://github.com/rnett/kotlin-js-action or https://github.com/hfhbd/kotlin-actions created by me.

[Max Kachinkin]

Hey @hfhbd! Thanks a lot! I’m looking into your repo.
You don’t use ncc or Webpack? Everything works fine without packing in one file?

[hfhbd]

No, you do need to package it in one file (unless you want to check in the node modules folder) and I use webpack. But it is managed by the Kotlin gradle plugin.

I see, thanks

I just want to create one KotlinJS GHA from scratch to figure everything out how it works.
