mongo-message-queue

A promise-based message queue for Node.js backed by MongoDB. Version 1.1.0 is the latest stable release. It provides a simple worker pattern where messages of a given type are processed by registered handlers, with built-in retry and rejection support. Compatible with MongoDB driver versions 4 through 6 and MongoDB server versions 5 through 7. Uses polling (default 1 second) to check for new messages. Differentiators: lightweight, no external dependencies besides MongoDB, and simple API.
