PlatformEventRule

EventBridge rule with shorthands for the platform event envelope.

Defaults

• Attached to the environment platform bus unless eventBus is given
• eventNames map to detail-type (the runtime publishes DetailType = event name, Source = service name); source and detailType add to the pattern; eventPattern is merged
• Targets (IFunction | IQueue | IStateMachine | ITopic) are wired with the right EventBridge target class
• deadLetterQueue: true creates <name>-dlq; retryAttempts and maxEventAge apply to every target

Alarms

alarms.failedInvocations(), alarms.deadLetter().

Example

new PlatformEventRule(this, "OnOrderEvents", {
  eventNames: ["order.created", "order.updated"],
  source: "checkout",
  targets: [worker, flow],
  deadLetterQueue: true,
}).alarms.failedInvocations();
