Supported scalars
Scalars represent the leaf values in the graph, either as part of key-value properties in shapes, or value of items in lists. You can learn more about scalars in the GraphQL specification.
Primitive types
The following scalars are part of the GraphQL specification.
Boolean
A true or false value.
Int
A signed 32-bit integer.
A range of valid values can be defined using
the @int directive.
Float
A signed double-precision floating-point value.
A range of valid values can be defined using
the @float directive.
String
A UTF-8 character sequence.
The @string directive must be used along with
String scalars to define the maxLength of the string.
Identifiers
The following scalars represent unique identifiers in the graph. In ComposedDB, they are all stored as string values.
ID
A Node identifier used by GraphQL.
By default, IDs are configured with a maxLength of 100. The
@string directive can be used along with ID
scalars to define a different maxLength as needed.
CommitID
Identifies a specific version of a Stream in the Ceramic network, following the CommitID specification.
DID
A Decentralized Identifier, representing an actor able to create and mutate Documents in the graph, using GraphQL Scalars.
StreamID
Identifies a specific Stream in the Ceramic network, following the StreamID specification.
Date and time
The following scalars can be used to store date and time values using standard representations.
Date
RFC 3339 compliant date string without time information, 2007-12-03 for
example, using
GraphQL Scalars.
DateTime
A date-time string at UTC, such as 2007-12-03T10:15:30Z, using
GraphQL Scalars.
Time
A time string at UTC, such as 10:15:30Z, using
GraphQL Scalars.
