Tanstack Start Best Practices

A solid reference for TanStack Start patterns that covers the full-stack basics you'll actually encounter. It organizes 33 rules across server functions, middleware, SSR, and auth into priority tiers, so you can focus on the critical stuff first like input validation and CSRF protection. The categorization by prefix (sf-, sec-, mw-) makes it easy to find what you need when you're debugging hydration issues or setting up session management. Honest take: it's comprehensive without being overwhelming, though you'll still need to understand TanStack Start fundamentals before diving into the advanced deployment and streaming patterns.
