Built in data types

Scalars

Boolean

Identifier: :boolean

The Boolean scalar type represents true or false.

Float

Identifier: :float

The Float scalar type represents signed double-precision fractional values as specified by IEEE 754.

ID

Identifier: :id

The ID scalar type represents a unique identifier, often used to refetch an object or as key for a cache. The ID type appears in a JSON response as a String; however, it is not intended to be human-readable. When expected as an input type, any string (such as "4") or integer (such as 4) input value will be accepted as an ID.

Int

Identifier: :integer

The Int scalar type represents non-fractional signed whole numeric values. Int can represent values between -(2^53 - 1) and 2^53 - 1 since represented in JSON as double-precision floating point numbers specified by IEEE 754.

String

Identifier: :string

The String scalar type represents textual data, represented as UTF-8 character sequences. The String type is most often used by GraphQL to represent free-form human-readable text.

Directives

skip

Identifier: :skip

Directs the executor to skip this field or fragment when the if argument is true.
