Atomic Queue

A crash-friendly queue for Node.js that persists queue state to disk and can safely restart after a crash. Uses a worker pool with configurable concurrency. Version 5.0.4 is the latest stable release; maintenance is infrequent. Key differentiators: zero external dependencies beyond core Node modules (LevelDB fork removed after v4), simple stream-based API, and automatic persistence of queue state. Compared to alternatives like Bull or Kue, it is minimal, with no Redis dependency. Primarily used in server-side applications requiring durable job processing without a dedicated message broker.
