Hi again, is there an easy way to convert Kotlin data classes (or normal classes) to JS objects? I have tried the Any.asJsObject() functions but that doesn't seem to do the trick.

My use case is that I'm trying to use the Firestore JS library to save some data but it only receives JS objects as input when trying to save data and I'm using normal Kotlin classes to handle this same data in the we app logic.

Do you use kotlinx-serialization ?

[Franco]

I do use it @turansky, but I didn't find a way to convert Kotlin classes to JS object there, only the opposite. Did I miss it somewhere?

[turansky]

kotlinx-serialization include both serialization & deserialization

[turansky]

JSON -> Kotlin Class
Kotlin Class -> JSON

[turansky]

Also supportted:
JS Object -> Kotlin Class (DynamicJbjectParser)

[Franco]

Yes but what I need is Kotlin class to JS Object

[Franco]

that is not covered in the stuff you mentioned above, JSON is not the same as JS Object as far as I understand (although I might be wrong as I'm pretty new to JS)

Untitled.kt

Untitled.kt

That doesn't seem to compile, I tried it in the Kotlin Playground and I got the error:

Type inference failed: Not enough information to infer parameter T in fun <T> parse(text: String): T Please specify it explicitly.

then I tried setting the value of T like this:

val jsObject = JSON.parse<JsObject>(jsonString)

and it failed with this error:

Uncaught SyntaxError: Unexpected token a in JSON at position 2

Did you try that code and it worked for you?

Oh cool, seems like setting the type to dynamic did the trick, thanks! 🙂
