Amazonka.AppSync.EvaluateCode

Evaluates the given code and returns the response. The code definition requirements depend on the specified runtime. For APPSYNC_JS runtimes, the code defines the request and response functions. The request function takes the incoming request after a GraphQL operation is parsed and converts it into a request configuration for the selected data source operation. The response function interprets responses from the data source and maps it to the shape of the GraphQL field output type.

Creating a Request

data EvaluateCode

See: newEvaluateCode smart constructor.

Constructors

EvaluateCode'

Fields

• function :: Maybe Text

  The function within the code to be evaluated. If provided, the valid values are request and response.

• runtime :: AppSyncRuntime

  The runtime to be used when evaluating the code. Currently, only the APPSYNC_JS runtime is supported.

• code :: Text

  The code definition to be evaluated. Note that code and runtime are both required for this action. The runtime value must be APPSYNC_JS.

• context :: Text

  The map that holds all of the contextual information for your resolver invocation. A context is required for this action.
