ElephantMQ

PostgreSQL-native job queue for Node.js 18+, featuring transactional enqueue, familiar producer/worker API, and no external broker. Current stable version 1.0.3. Releases are ad-hoc via npm. Key differentiators: atomic enqueue within database transactions via Queue.inTransaction, full SQL visibility into queue state, and one less datastore to manage vs Redis-based queues like BullMQ.
