Hi, is it possible to enforce required/optional fields in JSON serialization? It seems that kotlinx.serialization does the job of enforcing that fields should be required if no defaults are provided, but I was wondering if I can make some optional by saying it’s nullable with e.g. String? or Optional<String> ?

AFAIR, kotlinx.serialization can use default values from the constructor. Have you checked?

[bmarinovic]

yes, but that’s not really a same thing. I would have to check for each value is it default. And it would become bloated with complex classes

What do you want to do then? Aren't you requesting for something like @Serializable class MyData(val optionalString: String? = null) ?
