cfn-response-promise module
Promise wrapped version of cfn-response.
Why
to support the async await pattern that nodejs8.10 runtime provides.
The response.send method returns promise, so now you can write:
const response = require('cfn-response-promise')
exports.main = async (event, content) => {
return await response.send(event, context, response.SUCCESS, returnData);
}
Original cfn-response text
This module contains functions that respond on behalf of custom resources you create using AWS CloudFormation.
The module includes a send method, which sends a response object to a custom resource by way of a ResponseURL, which is an Amazon S3 pre-signed URL.
Any Lambda function using this module stops running after executing the module's send method.
