I have a class `data class(val foo: String, ...)` ...

# serialization

[akowal]

I have a class data class(val foo: String, ...) and in one context I need field foo to be serialized as bar (don’t need deserialization), but in
other cases it should be de-/serialized as usual. How is it possible to achieve this?

Create a KSerializer and use it depending on your context

That won’t help. Serializers are protocol agnostic and only define how values are serialized, it doesn’t have any control over how fields are named in json.

Ah you want to name it differently and not serialize it differently. Then go with a JsonTransformingSerializer
