TanStack Query Skill
When to use
- Introducing a new query/mutation.
- Debugging cache invalidation, stale data, or SSR hydration.
Workflow checklist
- Design a stable query key (include stable identifiers; avoid objects unless serialized).
- Co-locate query logic with the owning domain.
- Ensure SSR/hydration correctness (use Router + Query SSR integration patterns).
- Set cache semantics intentionally (staleTime/gcTime) and invalidate on writes.
- Keep devtools disabled in production.
SSR troubleshooting
- Identify which data must be available at SSR time vs client-only.
- Ensure query keys and inputs match across SSR and client hydration.
- Confirm provider wiring and dehydration/rehydration flow stays intact.
Tooling
- Use TanStack MCP for Query APIs, SSR patterns, and cache guidance.
