BullMQ

BullMQ is the standard Node.js/Bun job queue built on Redis. Priority queues, rate limiting, retries with exponential backoff, dead-letter queues, and scheduled jobs — all with a clean TypeScript API.

The separation of producers and consumers makes it easy to scale workers independently. We use it for document processing pipelines where ingestion, chunking, and embedding generation happen asynchronously. Redis as the backing store means no additional infrastructure beyond what you likely already run.
