Hi, is the anyway to access File System API in browser mode from kotlinJS?
i.e. https://web.dev/file-system-access/
It's important for me if I'm to create a PWA

[turansky]

No, but you can write it manually

external fun showSaveFilePicker(): Promise<Array<out FileHandle>>

[Hampus Londögård]

Thanks @turansky

[turansky]

Also you copy TypeScript existed definitions from lib.d.ts
TypeScript definitions - good source for Kotlin declarations

[Hampus Londögård]

Will make sure to look at that! 🙂

[turansky]

Definitions

@turansky is it possible to use Dukat somehow to autogenerate from that repo? Or I still need to write the full JS code and wrap it in my own types?

[turansky]

You can check Dukat result for start.
Most functions it will convert 🙂

[turansky]

In common case I add package, which missed in Dukat results

[turansky]

For “missed” browser extensions I have separate subproject

[altavir]

@Hampus Londögård yes, there is an option in gradle plugin to automatically generate wrappers under the hood: https://kotlinlang.org/docs/reference/js-external-declarations-with-dukat.html It is experimental and not fully accurate yet though.

having some issues with AsyncIterableIterator

[Hampus Londögård]

Note sure how i get that type/class included

[turansky]

You can declare it as external interface for start

[jessewilson]

You can use okio.FileSystem if you’d like a multiplatform one
https://square.github.io/okio/2.x/okio/okio/-file-system/index.html

implementation("com.squareup.okio:okio-multiplatform:3.0.0-alpha.1")

@jessewilson thanks. That seems really good!
