Oraq

Oraq (Ordered redis asynchronous queue) is a cross-process, cross-server, fast, reliable and lightweight redis-based async queue for Node.js (current stable version 0.2.4). It supports both queue (FIFO order) and limiter (rate limiting) modes, with features like concurrency control, job timeout, ping keep-alive, and LIFO support. Key differentiators: lightweight with minimal dependencies (only ioredis), simple API using a single Oraq class, and compatibility with Node.js >=7.6.0. Not actively maintained; last release in 2019.
