Scalars
The Boolean scalar type represents true or false.
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.
The Int scalar type represents non-fractional signed whole numeric values. Int can represent values between -(2^31) and 2^31 - 1.
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.
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).
The UInt8 scalar type represents unsigned 8-bit whole numeric values, ranging from 0 to 255.
