Scalars

Scalars are primitive values, like Int, Float, String, Boolean, or ID.

When calling a GraphQL API, you must specify nested subfields until you return only scalars.

For more information, see Scalars in GraphQL spec.

Boolean

Represents true or false values.

DateTime

An ISO-8601 encoded UTC date string.

Float

Represents signed double-precision fractional values as specified by IEEE 754.

ID

Represents a unique identifier. It is 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 M1ugvHj7C==) or integer (such as 7) input value will be accepted as an ID.

Int

Represents a signed 32-bit numeric non-fractional value. Int can represent values between -(2^31) and 2^31 - 1.

JSONObject

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

String

Represents textual data as UTF-8 character sequences. This type is most often used by GraphQL to represent free-form human-readable text.
