react-start

Implement TanStack Start server components by choosing between renderable fragments, composite components, and low-level Flight APIs based on your interaction model, then applying route loaders for data loading and cache invalidation.

Manage cache invalidation and SSR modes in React 19 by applying the correct invalidation strategy for route-shaped or query-owned data, ensuring Flight-serializable slot contracts are maintained during server and client boundary transitions.

Set up TanStack Start with React 19 by analyzing the current project shape and configuration to establish correct import boundaries, ensuring server functions and RSC fragments stay maintainable across server and client.

TanStack Start supports route loaders and server functions for data fetching by clarifying server and client boundaries, allowing you to decide where data should load and how refresh behavior works after mutations.

TanStack Start composite components fail during SSR when Flight-serializable slot contracts are violated, requiring correct server and client boundary enforcement and proper RSC fragment composition to resolve the issue.

Use route loaders versus query-owned data in a TanStack Start app by evaluating your data loading requirements and applying the appropriate SSR mode and invalidation strategy for route-shaped or query-owned data structures.
