JSON serializer written in Scala, which provides converters for:

• Int
• Float
• Double
• Boolean
• Char
• String
• List
• Array

For custom types you need to define custom implicit converter, e.g.

implicit object UserConverter extends JSONConverter[User] {
def convert(user: User): JSONValue = JSONObject(Map(
"name" -> JSONString(user.name),
"age" -> JSONInt(user.age),
"email" -> JSONString(user.email)
))
}

Then you can call stringify on your custom type to see result:

val john = User("John", 34, "john@mailbox.com")
println(john.toJSON.stringify)

Result:

{
    "name": "John",
    "age": 34,
    "email": "john@mailbox.com"
}
