FAQPage Schema
How do I secure server functions in TanStack Start?

Secure TanStack Start server functions by enforcing input validation and protecting endpoints through middleware. This ensures type-safe, robust server-side logic for data mutations and RPC.

What is the best way to implement authentication in a full-stack React app?

The best way to implement authentication in a full-stack React app is by enforcing secure session management and route protection. TanStack Start guidelines help structure these high-impact security patterns effectively.

How do I optimize SSR performance in TanStack Start?

Optimize SSR in TanStack Start by applying best practices for server-side rendering, streaming, and static prerendering. These techniques ensure faster load times and efficient data handling.

Does TanStack Start support middleware for route protection?

Yes, TanStack Start supports middleware for route protection. You can enforce secure session management and validate inputs across your application using high-impact middleware patterns.

How do I handle errors during SSR in React?

Handle SSR errors in React by following medium-priority error handling best practices. This ensures robust code organization and deployment readiness alongside optimized server-side rendering.

What are the limitations of using server functions for data mutations?

Server functions for data mutations require strict input validation and secure session management to prevent vulnerabilities. Without enforcing these critical security patterns, endpoints remain exposed to unauthorized access.
