In-Memory Queue

Simple in-memory job queue for Node.js (version 1.0.3, last updated 2018). It supports concurrent read/writes, retry mechanisms, parallel and series processing based on consumer priority, multiple consumers per topic, and topic-wise job distribution. Unlike Redis-backed queues (Bull, Bee), it has zero external dependencies and runs entirely in-process with no persistence. Key differentiators: consumer priority scheduling (lower priority numbers run first and in parallel), built-in retry, and promise-based API.
