Server-side rendering and server functions in TanStack Start are handled by a unified server runtime that orchestrates route matching, middleware, and app SSR into a single entry point.

Managing encrypted sessions and cookies in a TanStack Start app is best done through the server runtime's built-in session management, which provides a simple API for handling user state dehydration.

Server context during request handling works by requiring AsyncLocalStorage to maintain state, enabling consistent middleware integration and server function dispatch across the SSR workflow.

You need createStartHandler to wire server routes for production-grade rendering, as it connects your framework's server entry point to the runtime handling SSR and server function dispatch.

You can use TanStack Start middleware for server function dispatch and state dehydration, as the server runtime integrates routing execution with consistent state management across frameworks.

TanStack Start consolidates server utilities and request handling into a single runtime to enable consistent server behavior across frameworks, ensuring unified middleware and session management.
