Components

@pulumi/aws-serverless provides libraries to simply subscribe to many AWS events and to execute AWS lambdas in response to them. For example, bucket.onPut/onDelete/onEvent allow one to run an AWS lambda in response to the corresponding bucket event that is subscribed to.

All subscriptions allow the client to pass a preferred function.Handler instance to run when the subscription fires. This Handler can either be an AWS aws.lambda.Function instance (available through the @pulumi/aws library), or it can be an actual JavaScript/TypeScript function object (provided it has the right signature).

In the former case, the aws.lambda.Function resource can be one that the program has defined itself. Or it can just be a reference to an existing AWS Lamba that already exists in the client's cloud infrastructure.

In the latter case, the JavaScript/TypeScript function will be analyzed and 'serialized' out into a form suitable for use by an AWS Lambda that Pulumi will then create on behalf of the program. This can greatly simplify defining cloud-callbacks for AWS events by avoiding needing to manually construct and maintain the AWS Lambda yourself independently of the main cloud application.
