Guidance for Using MQTT.js in IoT-Based Web App (New to JavaScript)

[Kousalhs]

Hello! 👋

I'm completely new to JavaScript and currently working at a company where we build industrial automation systems. We're developing a web application that connects LS Electric PLCs (via MQTT) to a web dashboard where different types of users (admin, super user, citizen) can see or manage data like waste weight, time, and type.

We're planning to use MQTT.js in our backend (probably with Node.js) to subscribe to topics published by the PLCs and store this data in a database.

Could you please guide me on:

How should I get started with MQTT.js in this context?

What basics of JavaScript or Node.js should I study first?

Any best practices or examples for MQTT.js used in IoT/PLC-based applications?

I really appreciate any help or direction you can provide. 🙏
Thanks in advance!

I suggest to ask this kind of questions to ChatGPT/Claude or consider asking for paid support as the answer is articulated
