What's the proper way to do something like

import "some-library"

require("some-library")

) for a polyfill library so it can be loaded and can inject its globals before

main()

fun main() {
   require("some-library")
   // do the rest here
}

That doesn't work since the static initializers of another library I use run before this and require the polyfills.

Right now I've made a js file that requires the polyfills and I include that by adding it to the start of

config.entry.main

in my webpack config, but it doesn't feel like the best solution.

@JsModule("name") external val someShit: dynamic

Then just hold a reference to it in main() to avoid dce removal fun main() { someShit .... }

Does it matter if the module doesn't export a field like that? (it actually doesn't export anything)

It's just loading it for side effects

04/12/2023, 11:05 AM

alright, will give this a try, thanks ❤️

FYI someShit holds a reference to the entire module object, not its inner entities like fields or functions

04/12/2023, 11:06 AM

Ooooh, that makes a lot more sense

It's only with

@file:JsModule

that we deal with actually exported values yeah?

04/12/2023, 11:08 AM

Correct. @file unwraps module object and maps its properties to externals declared within the file

04/12/2023, 11:08 AM

Alright cool, didn't know there was a difference between the two. Good to know, thanks a lot.

This seems to work as expected 👍

You can use this trick to load any side effects like css or scss imports for example

04/12/2023, 11:12 AM

anything that webpack is configured to handle I assume?

04/12/2023, 11:13 AM

Yes. This is basically kt equivalent to this in js import "some-module" Or import "./some/file.scss"

You get the gist
