Building Simple Applications with Node.js and MQTT

In the evolving world of Internet of Things (IoT) and real-time applications, MQTT (Message Queuing Telemetry Transport) has emerged as a lightweight messaging protocol that’s perfect for small sensors and mobile devices. In this article, we’ll explore how to develop simple Node.js applications that communicate through an MQTT broker. This will give you a basic understanding of both MQTT and Node.js while allowing you to set up a simple messaging system between two applications.
