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.

--runtime (structure)

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

name -> (string)

The name of the runtime to use. Currently, the only allowed value is APPSYNC_JS .

runtimeVersion -> (string)

The version of the runtime to use. Currently, the only allowed version is 1.0.0 .

Shorthand Syntax:


JSON Syntax:

  "name": "APPSYNC_JS",
  "runtimeVersion": "string"

--code (string)

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 (string)

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

--function (string)

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

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
