Bases: Construct

(experimental) Abstract AppSync datasource implementation.

Do not use directly but use subclasses for concrete datasources

Example:

# api: appsync.GraphqlApi
# dummy_request: appsync.MappingTemplate
# dummy_response: appsync.MappingTemplate

info = appsync.ObjectType("Info",
    definition={
        "node": appsync.ResolvableField(
            return_type=appsync.GraphqlType.string(),
            args={
                "id": appsync.GraphqlType.string()
            },
            data_source=api.add_none_data_source("none"),
            request_mapping_template=dummy_request,
            response_mapping_template=dummy_response
        )
    }
)

Parameters:

name (str) – (experimental) the name of the AppSync Function.
description (Optional[str]) – (experimental) the description for this AppSync Function. Default: - no description
request_mapping_template (Optional[MappingTemplate]) – (experimental) the request mapping template for the AppSync Function. Default: - no request mapping template
response_mapping_template (Optional[MappingTemplate]) – (experimental) the response mapping template for the AppSync Function. Default: - no response mapping template

Stability:

experimental

Return type:

AppsyncFunction

create_resolver(*, field_name, type_name, caching_config=None, pipeline_config=None, request_mapping_template=None, response_mapping_template=None)

(experimental) creates a new resolver for this datasource and API using the given properties.

Parameters:

field_name (str) – (experimental) name of the GraphQL field in the given type this resolver is attached to.
type_name (str) – (experimental) name of the GraphQL type this resolver is attached to.
caching_config (Union[CachingConfig, Dict[str, Any], None]) – (experimental) The caching configuration for this resolver. Default: - No caching configuration
pipeline_config (Optional[Sequence[IAppsyncFunction]]) – (experimental) configuration of the pipeline resolver. Default: - no pipeline resolver configuration An empty array | undefined sets resolver to be of kind, unit
