Panko is a library which is inspired by ActiveModelSerializers 0.9 for serializing ActiveRecord/Ruby objects to JSON strings, fast.
To achieve its performance:
- Oj - Panko relies on Oj since it's fast and allows for incremental serialization using
Oj::StringWriter - Serialization Descriptor - Panko computes most of the metadata ahead of time, to save time later in serialization.
- Type casting — Panko does type casting by itself, instead of relying on ActiveRecord.
