json 2 case class

Kickstart your scala API client by turning JSON into case classes.

Try it at http://json2caseclass.cleverapps.io

Use cases

When interacting with 3rd party json-based APIs from scala, modelling the API's responses with case classes can come in handy. If the JSON exhibits some properties (homogenous lists, for instance), it's easy to create a case class with the same structure. With some deserialization magic it's easier to deal with the API's responses.

case class Foo(a: Bar, b: Bar, c: Double)
case class Bar(a: Option[String], b: String)

{
   "a": {
     "a": "fubar",
     "b": "fubar"
   },
   "b": {
     "b": "baz"
   },
   "c": 42.0
}

However it's tedious to manually copy the json structure into case classes.

json 2 case class automatically generates case classes from JSON (if possible).

Features

json 2 case class can generate

• nested case classes from JSON objects
• lists from JSON arrays
• scala base types from JSON primitives
• Option[T] for optional values

ToDo

Due to the arity limitation of 22 values, some JSON objects can't be encoded with case classes. A Map[String,T] fallback is on the works.

The code is on the project but not activated : need a UI support to choose between map and object
