# src/MyBundle/Resources/config/graphql/Human.types.yml
# We define our human type, which implements the character interface.
#
# This implements the following type system shorthand:
#   type Human : Character {
#     id: String!
#     name: String
#     friends: [Character]
#     appearsIn: [Episode]
#   }

        fields:
            id:
                type: "String!"
                description: "The id of the character."
                # to deprecate a field, only set the deprecation reason

# src/MyBundle/Resources/config/graphql/Droid.types.yml
#  The other type of character in Star Wars is a droid.
#
#  This implements the following type system shorthand:

With Annotations

Note: With annotations, you can omit the interfaces option. If so, the system will try to guess the interfaces automatically by getting the GraphQL Interface associated with classes that the Class type extends or implements.
