TriggerProps

class aws_cdk.triggers.TriggerProps(*, execute_after=None, execute_before=None, execute_on_handler_change=None, handler, invocation_type=None, timeout=None)

Bases: TriggerOptions

Props for Trigger.

Parameters:
  • execute_after (Optional[Sequence[Construct]]) – Adds trigger dependencies. Execute this trigger only after these construct scopes have been provisioned. You can also use trigger.executeAfter() to add additional dependencies. Default: []

  • execute_before (Optional[Sequence[Construct]]) – Adds this trigger as a dependency on other constructs. This means that this trigger will get executed before the given construct(s). You can also use trigger.executeBefore() to add additional dependants. Default: []

  • execute_on_handler_change (Optional[bool]) – Re-executes the trigger every time the handler changes. This implies that the trigger is associated with the currentVersion of the handler, which gets recreated every time the handler or its configuration is updated. Default: true

  • handler (Function) – The AWS Lambda function of the handler to execute.

  • invocation_type (Optional[InvocationType]) – The invocation type to invoke the Lambda function with. Default: RequestResponse

  • timeout (Optional[Duration]) – The timeout of the invocation call of the Lambda function to be triggered. Default: Duration.minutes(2)

Example:

import aws_cdk.triggers as triggers


func = lambda_.Function(self, "MyFunction",
    handler="index.handler",
    runtime=lambda_.Runtime.NODEJS_18_X,
    code=lambda_.Code.from_inline("foo")
)

triggers.Trigger(self, "MyTrigger",
    handler=func,
    timeout=Duration.minutes(10),
    invocation_type=triggers.InvocationType.EVENT
)
