tanstack-db

TanStack DB is a reactive client store built on differential dataflow that extends TanStack Query with collections, live queries, and optimistic mutations. It normalizes data into typed collections, enables sub-millisecond cross-collection queries, and provides instant optimistic updates with automatic rollback on failure.

When to use: Reactive UIs needing local-first data, cross-collection joins with live updates, optimistic mutations with automatic sync, real-time sync via ElectricSQL or other backends, apps that outgrow TanStack Query's per-query caching model.

When NOT to use: Simple fetch-and-display (TanStack Query alone suffices), server-components-only apps, purely synchronous local state (useState/Zustand), GraphQL with normalized caching (Apollo/urql).

실시간 쿼리 및 낙관적 변형이 포함된 TanStack DB 반응형 클라이언트 측 데이터베이스입니다. 로컬 우선 데이터, 동기화 엔진 또는 낙관적 업데이트를 사용하여 반응형 UI를 구축할 때 사용합니다. tanstack-db, 라이브 쿼리, 낙관적 돌연변이, 동기화 엔진, 반응형 데이터베이스, 로컬 우선에 사용합니다. 출처: oakoss/agent-skills.
