Aedes VS MQTT.js

Any reason to not use https://github.com/moscajs/aedes? mqtt is a standard protocol. I see there is an mqtt adapter for kafka, and a broker to translate between systems.

yes, we did it as well. We are using the aedes broker, wrapped inside its own module/service. Here you can find the broker lib https://github.com/moscajs/aedes

Any of the open-source MQTT brokers out there should do the job. I personally use Mosquitto for most of my projects, but RabbitMQ, Aedes or any other broker should all just work.

In Aedes, you can implement topic-level security with the authorizePublish and authorizeSubscribe handlers

First, we build two client simulators, for the car and the application client. We use MQTTJS for Javascript and its MQTT v5 implementation support. Step 1 below will describe the details of the MQTT client implementation.

We will simulate the device behavior using an MQTT client application built with the MQTT.js open-source library.

Change your javascript to use MQTT.js instead of the no longer actively maintained paho library: https://github.com/mqttjs/MQTT.js/

This all points to the direction that the underlying JS-Engine in the Streamdeck software might throttle the outgoing connections. I still don't understand what's under the hood. The user agent returns "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) QtWebEngine/6.3.1 Chrome/94.0.4606.126 Safari/537.36" What's the JS Engine in the Software? Is it Chrome? As far as I know, there are some issues with Websocket disconnects in Chrome due to aggressive throttling of background tabs. Could that be the cause here, too? https://github.com/mqttjs/MQTT.js/issues/1268

Let's take an example of programming with JavaScript, using the MQTT.js client. We can first specify the version of MQTT as MQTT 5.0 when connecting to the client.

MQTT.js is a fully open-source client-side library for the MQTT protocol, written in JavaScript and available for Node.js and browsers. On the Node.js side, it can be installed via global installation and connected via the command line. Also, it supports MQTT/TCP, MQTT/TLS, MQTT/WebSocket connections. It is worth mentioning that MQTT.js also has good support for WeChat Mini Program.

using MQTT.js to connect to the broker directly from the frontend through WebSockets.

MQTT.js is a client library of the MQTT protocol, written in JavaScript and used in Node.js and browser environments. It is currently the most widely used MQTT client library in the JavaScript ecosystem.
