A hands-on minicourse on the HTTP fundamentals that separate a prototype from a production service. You’ll tune Node’s HTTP agent (keep-alive, socket pools, timeouts), make retries safe with idempotency keys, layer in circuit breakers with Opossum, and pressure-test it all against a deliberately unstable upstream, so you understand why each setting matters, not just which one to copy.
This course is in active development. New lectures will be added over time. Existing lectures can be changed or removed at any time.
