How do you handle API security and auth?

By implementing JSON Web Tokens (JWT) or session cookies with HTTPOnly/Secure flags, rate limiting API paths, and enforcing strict CORS constraints.

How do you trace errors in high-throughput APIs?

We utilize centralized logging middleware that prints trace identifiers, mapping individual server errors to specific API requests.

We maintain persistent connection caches that reuse database pathways rather than spinning up connections for every API call.

By avoiding global variables, cleaning up file streams, checking event listeners, and running heap dump diagnostic tools.

We delegate compute-heavy calculations to secondary thread pools or decoupled worker queues to keep the main request loop free.

We structure route prefixes (like /api/v1) or utilize content negotiation headers to prevent breaking changes for existing users.
