Top IoT Libraries and Frameworks for JavaScript Developers

JavaScript and Node.js have expanded far beyond web development, playing a powerful role in the Internet of Things (IoT) ecosystem. Here is a list of 10 of the most widely used IoT libraries and tools available for JavaScript developers:
- Johnny-Five: One of the most famous and popular robotics and IoT frameworks built on Node.js, allowing seamless interaction with hardware like Arduino, Raspberry Pi, and various microcontrollers.
- Cylon.js: A robotics, ubiquitous computing, and IoT framework powered by JavaScript that supports a wide array of hardware devices and platforms.
- Node-RED: A flow-based programming tool developed by IBM that allows developers to visually wire together hardware devices, APIs, and online services using drag-and-drop nodes.
- JerryScript: An ultra-lightweight JavaScript engine designed to run on resource-constrained devices, such as microcontrollers with very limited RAM.
- NodeMCU: An open-source IoT firmware built on top of the popular ESP8266 Wi-Fi module, making hardware programming accessible with lightweight, user-friendly scripts.
- IoT.js: A platform designed to run JavaScript on IoT devices with small footprints and limited resources, often working alongside engines like JerryScript.
- IoT-Nodejs: A collection of tools and libraries optimized to leverage Node.js capabilities for developing smart IoT applications and gadgets.
- Node Serialport: A highly useful Node.js library that enables serial port communication with hardware ports, sensors, electronic boards, and peripherals via USB or terminal ports.
- Bit with Node.js / Plain JS: A tool for managing and sharing code components in JavaScript projects, helping IoT developers build modular, reusable code for hardware and software projects.
- Zetta: An API-first IoT platform built on Node.js that transforms any device—from sensors to cloud systems—into a web object, enabling easy management via RESTful APIs.
