The Life-Changing Magic of Kotlin Multiplatform Serialization
summary
Covers the kotlinx.serialization library that splits serialization vs encoding/decoding so a compile‑time compiler plugin generates serializer bytecode and a tiny runtime handles formats (JSON, ProtoBuf, CBOR; HOCON/YAML as JVM extras). One annotation (@Serializable) adds a companion.serializer that the JSON.stringify API uses; deserialization uses generated descriptors, a visitor pattern and a bitmask to track fields. Polymorphic types require register polymorphic subclasses in a module (no runtime reflection), the library is cross‑platform and usable in production today if you pin versions; schema generation/validation is planned.
