Backend API Design Decisions That Prevent Rewrite Later

#backend #api #restapi #architecture #esbuild #tdd #notification

Start with boundaries

The strongest backend systems begin with clear boundaries: auth, billing, notifications, and domain logic should not collapse into one controller layer.

API decisions that scale

  • Version public APIs deliberately.
  • Use idempotency for critical write operations.
  • Separate synchronous responses from async processing.
  • Document error contracts early.

Operational readiness

Good API design includes logs, metrics, and incident-friendly error messages. Stability is not just code correctness; it is recovery speed when something fails.
