Reference: Scalars

​

Boolean

The Boolean scalar type represents true or false.

​

Date

The Date scalar represents a Date value as specified by iso8601.

​

DateTime

The DateTime scalar type represents a DateTime value as specified by iso8601.

​

JSON

A JSON object.

​

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 - 1) and 2^31 - 1 since represented in JSON as double-precision floating point numbers specifiedby IEEE 754.

​

Float

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

​

JSONString

Allows use of a JSON String for input / output from the GraphQL schema.

Use of this type is not recommended as you lose the benefits of having a defined, static schema (one of the key benefits of GraphQL).

​

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.

​

UUID

Leverages the internal Python implementation of UUID (uuid.UUID) to provide native UUID objects in fields, resolvers and input.
