nodejs-queue-and-event-integration

Use when adding asynchronous work or event integration to a scaffolded Node.js service — wiring BullMQ, KafkaJS, or SQS producers and consumers with explicit delivery semantics, a transactional outbox, idempotent consumers, retry with backoff, and dead-letter handling, plus integration tests against a real broker via Testcontainers — after the service scaffold exists and the broker and contracts are declared in backend-architecture. Do not use for the service shell or config, auth or security review, observability vendor wiring, or performance and resilience gating; use the other Node.js archetype skills instead.
