How to parse a json string to a case class in scaja.js and vice versa

Question

A JSON string:

{
    "name": "Mike",
    "age": 111
}

A case class:

case class User(name:String, age:Int)

If I use scala, there are many libraries can let me convert the JSON to the case class and vice versa, but they can't be used in scala.js.

How to do this work in scala.js?

Deprecated repository for uPickle/PPrint. PPrint now lives at https://github.com/lihaoyi/pprint, and uPickle is deprecated in favor of https://github.com/playframework/play-json – Waldemar Wosiński Sep 09 '17 at 08:13

circe, can we used with scalajs as some other inherent java libs may required when import jar packages in scvalajs client side during final bundle js generataed with fatOptJS/fullOptJS. It may cause issue? – donald Sep 12 '18 at 03:58
uPickle is faster than Play-Json, Circe, or Argonaut by a large margin. – donald Oct 16 '18 at 07:14
