✅ Do	❌ Don’t
Log full stack traces and context (request IDs, payloads, etc.)	Continue running as if nothing happened
Report to external error‑tracking services (Sentry, Datadog, etc.)	Swallow errors or leave handlers empty
Gracefully shut down: close DB, stop accepting new requests	Call `process.exit(0)` (signals success)
Use a supervisor (e.g., PM2, Docker restart policy)	Believe you can recover 100% safely in‑process
Convert unhandled rejections into exceptions (`throw reason`)	Ignore Node.js v15+ default behavior—explicit is better
