Scalars

Boolean

The Boolean scalar type represents true or false.

Float

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

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

The Int scalar type represents non-fractional signed whole numeric values. Int can represent values between -(2^31) and 2^31 - 1.

JSONObject

The JSONObject scalar type represents JSON objects as specified by the ECMA-404 standard.

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.

UInt64

The UInt64 scalar type represents unsigned 64-bit whole numeric values. It is capable of handling values that are larger than the JavaScript Number type limit (greater than 2^53).

UInt8

The UInt8 scalar type represents unsigned 8-bit whole numeric values, ranging from 0 to 255.
