fec-data-fetching

Standardize server-state data fetching by establishing a clear boundary between server and UI state, applying stable cache keys, mutation invalidation, and consistent data flows across React, Vue, Solid, and Svelte.

Handle optimistic updates with rollback by defining structured mutation flows that enforce clear API boundaries, apply updates immediately, and automatically revert the local cache state when mutation errors occur.

Server-state caching for SSR workflows works by managing reliable hydration through structured cache keys and invalidation rules that synchronize server-fetched data with the client UI layer to prevent hydration mismatches.

TanStack Query is not required but is the primary target. The pattern provides guidelines for cache keys, mutation invalidation, and prefetching suitable for TanStack Query or equivalent data fetching layers.

UI state gets out of sync when components manage data ad-hoc. Enforcing a clear boundary between server-state and local UI state with proper mutation invalidation keeps the UI and API layers synchronized.

Yes, you can apply these data-fetching patterns across React, Vue, Solid, and Svelte. The approach enforces stable cache keys, clear API boundaries, and reliable SSR hydration for consistent workflows.
