## What it is
RSMQ is a lightweight message queue library for Node.js built entirely on Redis, requiring no dedicated queue server. It supports FIFO delivery, visibility timeouts, exactly-once delivery within the timeout, and optional promise-based APIs.

## Use cases
- replace amazon sqs with a redis-based queue
- send messages between node.js worker processes
- implement a lightweight job queue without extra infrastructure
- process background jobs with visibility timeouts
- queue tasks across multiple node.js services sharing one redis server

## When to choose
- you already run a Redis server and want a simple queue with no extra services
- you need a lightweight SQS-like queue for Node.js
- you want high throughput (10k+ messages/sec) with minimal dependencies

## When to avoid
- you need advanced features like dead-letter queues, fanout, or strict exactly-once guarantees
- you don't use Node.js or a language with an RSMQ port
- you need a durable queue that survives Redis data loss without persistence configured

## Facets
- artifact type: library
- maturity: stable
- function: message-queue, caching
- domain: backend, microservices, developer-tools
- platform: self-hosted
