What's your backend written with? JavaScript?!
summary
Claim: JavaScript works for backends — presenters build and run small microservices: a REST coffee/tea API with NestJS, typed models with TypeScript, and WebSocket streaming (Socket.IO) that actually serves events. They demonstrate controllers, providers and modules, health endpoints, distributed tracing, and horizontal scaling on Kubernetes. Notes: big users include Netflix PayPal NASA, single‑threaded event loop blocks on heavy CPU tasks, database syncing and shared libraries cause real pain, and chaos‑engineering tests reveal reliability gaps.
