Basic MQTT Publisher using JavaScript

Overview

The Basic MQTT Publisher using JavaScript is a versatile and lightweight script designed to generate random values at configurable intervals and publish them to any MQTT broker (local or cloud-based). This solution is ideal for industrial automation, IoT prototyping, protocol conversion, and remote monitoring applications where simulated or test data is required.

Built with simplicity and flexibility in mind, this JavaScript-based publisher can run on Linux SBCs (Raspberry Pi, BeagleBone), edge devices, Windows machines, or even inside Docker containers, making it a universal tool for MQTT data simulation.

Key Features

✅ Random Data Generation – Publishes randomized payloads at user-defined intervals.
✅ Universal MQTT Broker Support – Works with local brokers (Mosquitto, EMQX, HiveMQ) or cloud brokers (AWS IoT, Azure IoT, ThingsBoard, etc.).
✅ Lightweight & Cross-Platform – Runs anywhere JavaScript is supported (Node.js environment).
✅ Configurable Publishing Rate – Adjustable intervals for data transmission.
✅ Raw Payload Support – Publishes data in raw format for seamless integration with SCADA, IIoT platforms, and dashboards.
✅ Easy Deployment – No complex dependencies; ready to run on edge devices, single-board computers (SBCs), or servers.
✅ Ideal for Testing & Simulation – Perfect for protocol conversion, uni-directional data publishing, and remote monitoring setups.
