Angular 2 and WebSockets
summary
Builds an Angular 2 quiz that connects browsers directly to AWS IoT over WebSockets using MQTT, a pure front‑end “backendless” setup that uses the mqtt.js library plus AWS SDK signing. State is captured with event sourcing in localStorage and replayed with a simplified Redux pattern while RxJS streams handle incoming and outgoing messages. A live demo hits ~225 concurrent users and reports near real‑time updates. Problems: an 18 MB bundle from webpack, immature Material components, and missing tests.
