Format encoder for phoenix. Converts all the keys of the json data to camel case.

Usage

Add Casex.CamelCaseEncoder as json format encoder for phoenix:

# config.exs
config :phoenix, :format_encoders, json: Casex.CamelCaseEncoder

Now all outcoming json response bodies will be converted to camel case.

Structs

If you want to control how the keys will be serilized before being encoded by Jason, you can provide a implementation for the Casex.Serializable protocol, by default it will return the structs as they come, without any transformation.
