Salat is a simple serialization library for case classes.

Salat currently supports bidirectional serialization for:

  • MongoDB's DBObject (using casbah)
  • JSON (using JSON4S)
  • maps


Simplicity. Flexibility. Consistency.

Your model there and back again should just work.

What does Salat support?

See Supported Types.

What doesn't Salat support?

We don't have the resources to support everything. Here are some things Salat doesn't do:

  • Java compatibility
  • non-case classes
  • type aliases
  • nested inner classes
  • varags
  • arrays
  • multiple constructors
  • tuples
  • Option containing a collection (see collection support for workarounds)
  • relationship management like a traditional ORM

How does Salat work?

Salat uses the Product trait implemented by case classes with the hi-fi type information found in pickled Scala signatures.

Details are thin on the ground, but here's where we got started:
