TanStack Integration Best Practices
Guidelines for integrating TanStack Query, Router, and Start together effectively. These patterns ensure optimal data flow, caching coordination, and type safety across the stack.
When to Apply
- Setting up a new TanStack Start project
- Integrating TanStack Query with TanStack Router
- Configuring SSR with query hydration
- Coordinating caching between router and query
- Setting up type-safe data fetching patterns
Rule Categories by Priority
| Priority | Category | Rules | Impact |
|---|---|---|---|
| CRITICAL | Setup | 3 rules | Foundational configuration |
| CRITICAL | SSR Integration | 1 rule | Router + Query SSR setup |
| HIGH | Data Flow | 4 rules | Correct data fetching patterns |
| MEDIUM | Caching | 3 rules | Performance optimization |
| MEDIUM | SSR | 2 rules | Additional SSR patterns |
Quick Reference
Setup (Prefix: setup-)
setup-query-client-context— Pass QueryClient through router contextsetup-provider-wrapping— Correctly wrap with QueryClientProvidersetup-stale-time-coordination— Coordinate staleTime between router and query
Data Flow (Prefix: flow-)
flow-loader-query-pattern— Use loaders with ensureQueryDataflow-suspense-query-component— Use useSuspenseQuery in componentsflow-mutations-invalidation— Coordinate mutations with query invalidationflow-server-functions-queries— Use server functions for query functions
Caching (Prefix: cache-)
cache-single-source— Let TanStack Query manage cachingcache-preload-coordination— Coordinate preloading between router and querycache-invalidation-patterns— Unified invalidation patterns
SSR Integration (Prefix: ssr-)
ssr-dehydrate-hydrate— Use setupRouterSsrQueryIntegration for automatic SSR
Additional SSR (Prefix: ssr-)
ssr-per-request-client— Create QueryClient per requestssr-streaming-queries— Handle streaming with queries
