Mosca is a Node.js MQTT broker that can run standalone or be embedded in any Node.js application. It supports MQTT 3.1/3.1.1 with QoS 0 and 1, pluggable storage backends like MongoDB and Redis, and WebSocket connections, but the project is officially unmaintained in favor of Aedes.
Use cases
- run an mqtt broker for iot devices
- embed an mqtt broker in my node.js app
- broker mqtt messages with qos 1 offline packet storage
- serve mqtt over websockets in node.js
- persist mqtt subscriptions to mongodb or redis
When to choose
- you need a lightweight embeddable MQTT broker inside an existing Node.js application
- you want pluggable persistence backends for MQTT QoS 1 packets
When to avoid
- you need a maintained or production-supported MQTT broker — use Aedes or Mosquitto instead
- you need MQTT 5 support or modern Node.js versions
