API

$3

Returns an object-mode readable stream
which emits StackEvent objects as returned by describeStackEvents

Required parameters:

* cfn: An AWS::CloudFormation instance.
* stackName: The name or ARN of the stack. Note that if you are reading events for a stack that is deleted or in the
process of being deleted, you need to pass the full ARN rather than the stackName.

Options:

* lastEventId: The EventId of a StackEvent`. StackEvents emitted by the resulting stream
are guaranteed not to include this event or any preceding events.
