node-redis-queue

A lightweight queueing wrapper for Redis using lpush/brpop, providing Channel (push/pop) and WorkQueueMgr (send/consume) interfaces for inter-process communication. Version 0.2.5 (last released around 2014) is stable but unmaintained; no releases in the last decade. Differentiators: simple synchronous blocking pop with timeout, full-duplex mode via two Redis connections to avoid hangs, and tunable concurrency (arity) for consumption. Alternatives with active maintenance include Bull, BullMQ, and Bee-Queue.
