Debouncing (React / Zod / data fetching)

• Debouncing delays work until input “settles”, preventing noisy UX and excessive computation/requests.
• Zod validation timing:
  • onSubmit: always validate full schema (final gate).
  • onBlur: good default for field-level feedback.
  • onChange: use when it improves UX; debounce to avoid flashing/errors per keystroke.
• tRPC availability checks:
  • Debounce the query trigger.
  • Gate calls (e.g. valid email + min length).
  • Prevent stale wins (cancel, or track a request id and ignore older results).
• useEffect + fetch:
  • Debounce the effect (timeout).
  • Use AbortController (or request id) in the cleanup to cancel/ignore stale requests.
