  • [internal] Refactored introspection directives

  • Added graph schema directives support

  • Added Deprecated directive

    from hiku.directives import Deprecated

graph = Graph([
    Root([
        Field('lorem-ipsum', String, func,
              options=[Option('words', Integer, default=50)],
              directives=[Deprecated('use another field')]),
    ]),
])

    Or you can use deprecated argument to hiku.graph.Field: or hiku.graph.Link:

    from hiku.directives import Deprecated

graph = Graph([
    Root([
        Field('lorem-ipsum', String, func,
              options=[Option('words', Integer, default=50)],
              deprecated='use another field'),
    ]),
])

  • Added mypy and typings to codebase

  • Added checks for link results that can not be hashed and extend errors. This must improve developer experience.

  • Added result cache - it is possible now to specify @cached directive to cache parts of the query. Check cache documentation

  • Link(requires=['a', 'b']) can be specified as a list of strings. It is useful when you want to require multiple fields at once. It will pass a list of dicts to the resolver.

  • Added hints when failing on return values that are not hashable

  • Migrated to pdm package manager

  • Reformat code with black

  • Added support for custom schema directives Check directives documentation

  • Added ID type.

  • Added support for unions Check unions documentation

  • Added support for interfaces Check interfaces documentation

  • Added support for enums Check enums documentation

  • Added support for custom scalars Check custom scalars documentation

  • Added support for extensions Check extensions documentation

    • Added QueryParseCache extension - cache parsed graphql queries ast.

    • Added QueryValidationCache extension - cache query validation.

    • Added QueryDepthValidator extension - validate query depth

    • Added PrometheusMetrics extension - wrapper around GraphMetrics visitor

    • Added PrometheusMetricsAsync extension - wrapper around AsyncGraphMetrics visitor

  • Add new method Engine.execute_context, which accepts ExecutionContext. Engine.execute now dispatches to Engine.execute_context.

  • Add new method Engine.execute_mutation, which allows to execute query against mutation graph

  • Add optional context argument to GraphqlEndpoint.dispatch method

Backward-incompatible changes

  • Dropped Python 3.6 support, minimum supported version now is Python 3.7

  • Validate Option’s default value. Now if type is not marked as Optiona[…] and default=None, validation will fail.
