Annotations

AutoSchema has a few annotations that you can use to customize generated schema

Description

Lets you manually define comments for case clases and fields which are translated in a description field of the commented element in the JSON schema.

    @Description("This is my class")
    case class MyClass(@Term.Description("This is my field") myField: String)

FormatAs

Lets you manually set the type and format values of the schema to be generated for a specific type or value

On a Type

    @FormatAs("string", "date")
    case class MyDateType

On a Value

    case class MyType(@Term.FormatAs("string", "date") date: String)

ExposeAs

Lets you use the schema of some type as the schema for another type or value

On a Type

    @ExposeAs[Int]
    case class MyIntLikeType

On a Value

    case class MyType(@Term.ExposeAs[Id] id: MyTypeId)

Hide

Lets you hide a value in generated schema

    case class MyType(@Term.Hide mySecretField: Int)
