Below is a json example of Twitter's tweet. It's a large json. What is the best library/method to parse it into a case class in scala?
For instance, in Play Framework 2.x it's possible to do that with it's internal library by defining case classes and implicit conversions, but in this case I don't use Play. Should I?
spray-json seems to be most popular scala json library, but in this case it looks quite disappointing - standard approach seems to be limited to 22 elements and uses pattern matching, which becomes ridiculous in the context of multi nested structure with hundreds of elements. Any ideas?
