Hey all, I'm looking for a low-level JSON library ...

Hey all, I'm looking for a low-level JSON library like klaxon that works in a MPP. (Unfortunately I'm dealing with a nasty REST API and simple serialization isn't really flexible enough.) Any suggestions?

[Dominaezzz]

Kotlinx.serialization?

[bsimmons]

Yeah, I've been looking through the documentations, but there doesn't seems to be a way to manually create a JsonObject by hand.

I saw this repo the other day which looked interesting and might be what you need, though I haven’t actually tried it https://github.com/kittinunf/Forge

[gabin]

it can be created by json{} builder as well

[bsimmons]

@gabin Looks promising, I can't seem to find any documentation on that. Where can I find the builder?

[gabin]

json { "additional key" to "value" }

https://github.com/Kotlin/kotlinx.serialization/blob/master/runtime/commonMain/src/kotlinx/serialization/json/Json.kt

[bsimmons]

Hmmm, that's interesting. Just trying that out now. So it's basically converted a map to a JsonObject? I'm new to kotlin, which lines in the file you like do this?

[bsimmons]

(I'm just wondering, so that I can find clever features like this in the future.)

[gabin]

it’s not basically a map. It makes json object from key-value pairs
val jsonBody = json { "user" to user, "email" to email }
You can see examples of json creation at the header of Json.kt file or search through kotlinx.serialization docs

[bsimmons]

Ok, cool. Admittedly, I couldn't find any examples of this anywhere in the docs beyond that brief example in the source files.

Thanks for the help though!
