Hi!
How do I generate an executable file from JS?

I have

kotlin {
    js(IR) {
        nodejs()
        binaries.executable()
    }
}

as my setup, and when running build it outputs a JS file to build/js/packages/..., but files from resources are nowhere to be found over there. What's the proper way to generate a executable file that works on its own?

If you need independent js dist for now:
1. Use browser() instead of node()
2. Use build/distributions/ as dist source

[LeoColman]

By doing that I'm not able to execute it in a NodeJS environment, right?

[LeoColman]

There's no way to generate a runnable node file?

[LeoColman]

On M1 there's this:

Please note that since this is only a preview, they are not added to the distributions folder by default for now

[LeoColman]

How to add it manually then?

[turansky]

Gradle copy task 🙂

[LeoColman]

Ah, I see... I thought there would be a solution out of the box 😂

[LeoColman]

Thanks, @turansky !

In M3 resources copied automatically

[turansky]

From src/main/resources

[turansky]

Try run ./gradlew clean before to refresh Kotlin/JS settings

I'm using M3 tho... I'll create an example project

[LeoColman]

Executing gradlew build won't carry the file in resources to the package directory

[turansky]

Check please build/distributions dir of subproject

[turansky]

browser() required instead https://github.com/LeoColman/KotlinJSM3/blob/master/build.gradle.kts#L10

[LeoColman]

I know browser works, but I need it for node. I'm not using Kotlin JS in a browser

[turansky]

For now node is just limited browser

[turansky]

FYI

browser uses window, which is not defined in a node environment

[LeoColman]

It's not possible to use

[Ilya Goncharov [JB]]

Yes, for now nodejs doesn’t have its own bundle task, if you need some resources you can manually copy it
If you use browser there is way to make it possible to run in Node.JS environment, you need change configuration for webpack in webpack.config.d. You need to create this folder in your project and create any js file with content

config.output = config.output || {}
config.output.globalObject = “this”

It will be fixed in 1.4.20 (https://youtrack.jetbrains.com/issue/KT-40159)
