Getting Rid of Scala Enums and Clean Json Serialization

EnumReplacement.scala

sealed case class Color(value: String)
object Color {
  object red extends Color("red")
  object green extends Color("green")
  object blue extends Color("blue")
}

// pattren matching
val x = Color.red
val y = Color.green
val z = "pink"
Color(z) match {
  case Color.red => println("color is red")
  case _ => println("unknown color") // prints: unknown color
}

// json serialization without any special case like enums
case class Person(name: String, favColor: Color)
val person = Person("Abhishek", Color.red)
import io.circe._, io.circe.generic.auto._, io.circe.parser._, io.circe.syntax._
val json = person.asJson.noSpaces
println(json) // prints: {"name":"Abhishek","favColor":{"value":"red"}}
val person2 = decode[Person](json)
println(person2) // prints: person2: Either[Error, Person] = Right(Person("Abhishek", Color("red")))
