The answer is probably "no", but just to be sure: Is there something like Java's

ServiceLoader

for pure Kotlin, i.e. can be used in a multiplatform project?

No, but it should be pretty easy to write own service locator for your code

Is there a pure-kotlin resource-access mechanism? Something like

Class.getResource

?

Resources is Java specific API

Yes, I know that. Question is, what would I do on the JS side?

Depends on your use case. There is no default js way to do that

Ok, that was my question, thanks.

Also js can be client and server side with different API set in each case

Yeah, I know. I was hoping Kotlin would provide something here to embed resources into final build artifact (.js file).

Nope. But you can provide them using expect/actual methods and implement on each platform. Depends on resource type. Probably you want to download it on client side and bundle to resources on server side

Yeah. I'll have to do some experiments. Thanks!
