I am kinda confused about using Json-Parser on Kotlin-Native to serialize and deserialize a data class. Are there any samples or resources for this?

[thevery]

Not supported yet, see https://github.com/Kotlin/kotlinx.serialization/issues/86

I was looking at https://github.com/ktorio/ktor/tree/master/ktor-client/ktor-client-features/ktor-client-json and they have kind of a wrapper in the common code in KotlinxSerializer.kt and was pretty excited/confused as its also supported in Native

[thevery]

Only JsonReader/Writer supported for native yet

[Mohit Gurumukhani]

I mean that’s kinda what I want? To read json and convert it to data class and vice versa?

[thevery]

JsonReader == JsonReader(string).getLong(key)

But you want full data binding:

@Serializable
data class Data(val a: Int, @Optional val b: String = "42")

fun main(args: Array<String>) {
    println(JSON.stringify(Data(42))) // {"a": 42, "b": "42"}
    val obj = JSON.parse<Data>("""{"a":42}""") // Data(a=42, b="42")
}

Full data binding in K/N is not yet supported, so you have to write serializers by hand with json builders:
