A WebSocket proxy to an MQTT broker backend.
npm install -g ws2mqtt
Run a WebSocket server that proxies messages to an MQTT broker.
ws2mqtt [-h <websocket-host>] [-p <websocket-port>] [-c <mqtt-broker-url>]
[--debug]
Options:
--help Show help [boolean]
--version Show version number [boolean]
-h, --host WebSocket server host [string] [default: "localhost"]
-p, --port WebSocket server port [number] [default: 3000]
-c, --broker Connection URL to an MQTT broker
[string] [default: "mqtt://localhost:1883"]
-d, --debug Print debug info [boolean] [default: false]
Once the proxy is running, connect to the WebSocket server using the following URL format:
http://{host}:{port}/{+topic}{?action}
Where host and port reference the values used when starting the proxy, topic matches the MQTT topic (e.g., myhome/temperature), and the action query string parameter equals publish or subscribe.
Test your proxy with the WebSocket Proxy to MQTT Broker Postman collection!
