How can I access str.prototype.normalize using Kotlin/JS?

[Patrick]

Or a more general question: How can I access the js api from Kotlin? What do I need to import?

[altavir]

js(...) is a literal js injection

[Patrick]

Oh I see so I need to write something like js("'test'.normalize()") ?

[altavir]

Eah, probably. Here is the reference page: https://kotlinlang.org/docs/reference/js-interop.html#inline-javascript

js function isn’t recommended in common case

[turansky]

You can write custom extension:

fun String.normalize():String =
    asDynamic().normalize()

[altavir]

Using js functions instead of stdlib also is not recommended.

[Patrick]

Well yes I could write it myself but that would mean I have to write the function myself 😆

[Patrick]

I can access the Java std lib on JVM and the WIN32 API on Windows. Why can’t I access the JS std lib?

[altavir]

Because you need kotlin wrappers for them. Most of those are present in stdlib-js

[Patrick]

Yes that’s what I was thinking but the string class is apparently not one of them

[altavir]

You have kotlin string for that. I am not sure. but maybe you could find something in kotlin.text

[Patrick]

Nope, Kotlin stdlib doesn’t have string normalization

[Patrick]

That would be the easiest solution of course

[altavir]

Then the solution from @turansky is the best you can do. It is no quite different from js inlining, but looks better.

[Patrick]

Thanks, I’ll give it a try

[Patrick]

This seems to work, thanks 👍
