Building your Own Internet of Things with JavaScript
summary
Shows a complete JavaScript-based IoT stack: tiny-device runtime JerryScript (~64 KB RAM footprint, ~160 KB ARM binary) running on Raspberry Pi Zero, a Node.js-based Mozilla WebThings gateway, and a clap-detection add-on that toggles a blinky LED — demo works live. Covers platform glue (iot.js/JS modules for GPIO), gateway security (Let's Encrypt certificates, PageKite tunneling, JSON Web Tokens), the Web Things API for thing descriptions and REST/WebSocket control, and deployment notes for constrained devices and Raspberry Pi 3 gateways.
