Would it possible to run the compiler in JavaScript or does it need some JVM/C (?) api to compile Kotlin to JavaScript (IR) in your browser? Use case is a local Kotlin web playground

You'll need JVM to run the compiler for sure :)

Btw, I am pretty sure JB has a playground on Kotlin website, it should be embeddable (or maybe sources are available somewhere)

[hfhbd]

Hm.
Yeah, I do know the Kotlin playground by JB, but AFAIK its not possible to execute the resulting JS in your JS app. And it still requires a JVM backend.

If you ask about compiling kotlin compiler for target other than JVM, then it is absolutelly impossible - it has many dependencies on JVM and JVM libraries. It even has a good about of remaining java source files, although they could be threoretically translated to kotlin quite eaisly.

if you were very motivated, you could try running the Kotlin compiler with TeaVM (which converts JVM bytecode to JS). I wouldn't find it much fun, though.

[ephemient]

you can customize and run the playground yourself though - see https://github.com/JetBrains/kotlin-playground

[shikasd]

^^^ yep, that's what I was thinking of earlier
You could also just have server call Kotlinc and return/execute resulting JS, if it is feasible for your project

Thanks for the information!
The project does not exists yet, so I will try to prototype it with kotlin-playground first.
