# TanStack Router Best Practices Comprehensive guidelines for implementing TanStack Router patterns in React applications. These rules optimize type safety, data loading, navigation, and code organization. ## When to Apply - Setting up application routing - Creating new routes and layouts - Implementing search parameter handling - Configuring data loaders - Setting up code splitting - Integrating with TanStack Query - Refactoring navigation patterns ## Rule Categories by Priority | Priority | Category | Rules | Impact | |----------|----------|-------|--------| | CRITICAL | Type Safety | 4 rules | Prevents runtime errors and enables refactoring | | CRITICAL | Route Organization | 5 rules | Ensures maintainable route structure | | HIGH | Router Config | 1 rule | Global router defaults | | HIGH | Data Loading | 6 rules | Optimizes data fetching and caching | | HIGH | Search Params | 5 rules | Enables type-safe URL state | | HIGH | Error Handling | 1 rule | Handles 404 and errors gracefully | | MEDIUM | Navigation | 5 rules | Improves UX and accessibility | | MEDIUM | Code Splitting | 3 rules | Reduces bundle size | | MEDIUM | Preloading | 3 rules | Improves perceived performance | | LOW | Route Context | 3 rules | Enables dependency injection | ## Quick Reference ### Type Safety (Prefix: `ts-`) - `ts-register-router` — Register router type for global inference - `ts-use-from-param` — Use `from` parameter for type narrowing - `ts-route-context-typing` — Type route context
