An async/await module for sending responses from lambda-funciton backed custom resources in AWS CloudFormation
npm install cfn-response-asyncAsync / Await alternative to the cfn-response module
Please Read The Documentation
The cfn-response module can be tricky, it is sometimes injected automagically and sometimes not. For a full understanding, please read the documentation [here][1].
Specifically pay attention to the following:
> Note
>
> The cfn-response module is available only when you use the ZipFile property to write your source code. It isn't available for source code that's stored in Amazon S3 buckets. For code in buckets, you must write your own functions to send responses.
If you notice the code here is out of sync with the latest, official version from Amazon, please send a pull request and link to where Amazon has posted the latest code.
$ npm install cfn-response-async
`Sample usage:
`typescript
import { CloudFormationCustomResourceEvent, Context } from 'aws-lambda';
import { send, SUCCESS } from 'cfn-response-async';export const handler = async (event: CloudFormationCustomResourceEvent, context: Context) {
console.log('request:', JSON.stringify(event, undefined, 2));
await send(event, context, SUCCESS, {
Response:
Hello, async/await CustomResource
});
};
`Note: The example also assumes you've installed
