functionName​

Type​

(string | ParameterConfig)!

Description​

Allows mapping from the QueryContext to create a FunctionName for the Lambda resolver invocation. serialize.template is used to place the tokens in the functionName string.

Example​

Schema
{
  "MyLambdaQuery": {
    "resolver": {
      "name": "awsLambda:invoke",
      "service": "aws",
      "functionName": {
        "ops": [
          {
            "path": "acct",
            "value": "12345678"
          },
          {
            "path": "region",
            "value": "us-east-1"
          },
          {
            "path": "fn",
            "mapping": "myFunction"
          }
        ],
        "serialize": {
          "template": "{acct}:{region}:function:{fn}"
        }
      }
    }
  }
}
Result
var functionName = '12345678:us-east-1:function:myFunction';

payload​

Type​

ParameterConfig?

Description​

Allows mapping from the QueryContext to create a Payload for the Lambda resolver invocation.

Example​

Context
var $args = {
  price: '123',
  couponCode: 'FREE_STUFF'
};
Schema
{
  "MyLambdaQuery": {
    "resolver": {
      "name": "awsLambda:invoke",
      "service": "aws",
      "payload": {
        "ops": [
          {

          },
          {
            "path": "coupon",
            "mapping": "$args.couponCode"
          }
        ]
      }
    }
  }
}
Result
var payload = {
  price: '123',
  coupon: 'FREE_STUFF'
};

clientContext​

Type​

ParameterConfig?

Description​

Allows mapping from the QueryContext to create a ClientContext for the Lambda resolver invocation. This object will be base64 encoded per the AWS spec and it should not exceed 3583 bytes.

Example​

Schema
{
  "MyLambdaQuery": {
    "resolver": {
      "name": "awsLambda:invoke",
      "service": "aws",
      "payload": {
        "ops": [
          {
            "path": "userName",
            "value": "dunefan10191"
          }
        ]
      }
    }
  }
}
Result
var clientContext = 'eyJ1c2VyTmFtZSI6ImR1bmVmYW4xMDE5MSJ9';
