Network.AWS.AppSync.CreateResolver

Creates a Resolver object.

A resolver converts incoming requests into a format that a data source can understand and converts the data source's responses into GraphQL.

Creating a Request

createResolver

Arguments

:: Text

crApiId

-> Text

crTypeName

-> Text

crFieldName

-> Text

crDataSourceName

-> Text

crRequestMappingTemplate

-> CreateResolver

Creates a value of CreateResolver with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• crResponseMappingTemplate - The mapping template to be used for responses from the data source.
• crApiId - The ID for the GraphQL API for which the resolver is being created.
• crTypeName - The name of the Type .
• crFieldName - The name of the field to attach the resolver to.
• crDataSourceName - The name of the data source for which the resolver is being created.
• crRequestMappingTemplate - The mapping template to be used for requests. A resolver uses a request mapping template to convert a GraphQL expression into a format that a data source can understand. Mapping templates are written in Apache Velocity Template Language (VTL).

Request Lenses

crResponseMappingTemplate :: Lens' CreateResolver (Maybe Text)

The mapping template to be used for responses from the data source.

crApiId :: Lens' CreateResolver Text

The ID for the GraphQL API for which the resolver is being created.

crTypeName :: Lens' CreateResolver Text

The name of the Type .

crFieldName :: Lens' CreateResolver Text

The name of the field to attach the resolver to.

crDataSourceName :: Lens' CreateResolver Text

The name of the data source for which the resolver is being created.

crRequestMappingTemplate :: Lens' CreateResolver Text

Destructuring the Response

createResolverResponse

Arguments

:: Int

crrsResponseStatus

-> CreateResolverResponse

Creates a value of CreateResolverResponse with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• crrsResolver - The Resolver object.
• crrsResponseStatus - -- | The response status code.
