node-js best practices we enforce in code review

A concrete checklist for reviewers working in nodejs repositories—especially when NodeLib patterns are in play.

The checklist

  1. Boundary validation — schemas match what clients can send; reject early with stable error codes.
  2. Error mapping — internal failures do not leak stack traces externally.
  3. Logging fields — correlation identifiers exist and are consistent across node hops.
  4. Timeouts — outbound calls have explicit deadlines and cancellation behavior.

Why checklists beat slogans

Slogans do not survive incidents. Checklists survive onboarding. For node-js teams, the goal is repeatable review language that maps to measurable production signals.
