mongodb-queue-up

A lightweight message queue implementation built on MongoDB, forked from mongodb-queue@4 to add support for MongoDB Node.js Driver v4, v5, v6, and v7. Version 5.5.0 is stable and feature-complete. Key differentiators: zero external dependencies beyond MongoDB driver, simple callback-based API, message visibility timeout and delay configuration, built-in indexing and cleanup. Compared to alternatives like Bull or Bee-Queue, it leverages existing MongoDB infrastructure without additional services.
