mqtt / nuxt 3 - Uncaught ReferenceError

[briankandersen]

As soon as I try to call the mqtt connect function, I get this error in the console:

Uncaught ReferenceError: Buffer is not defined
at node_modules/mqtt-packet/constants.js

Has anybody successfully gotten mqttjs to work in nuxt 3?

Hope the following code is useful to you

import * as mqtt from "mqtt/dist/mqtt.min";

if (process.client) {
  const client = mqtt.connect("ws://broker.emqx.io:8083/mqtt");
  console.log("mqtt client", client);
}

in addition, refer to the MQTT.js issue: mqttjs/MQTT.js#1269, you should do like this:
