rp-queue

A lightweight promise queue for Node.js (v4+) that runs tasks with concurrency control, rate limiting, and priority support. Version 1.1.0 is the current stable release; updates are infrequent. Key differentiators include support for both simple task arrays and object-style configurations with custom process functions, as well as FIFO and priority queue modes. Unlike larger libraries like Bull or Bee-Queue, rp-queue is minimal and has no dependencies.
