TanStack DB — Core Concepts

TanStack DB is a reactive client-side data store. It loads data into typed collections from any backend (REST APIs, sync engines, local storage), provides sub-millisecond live queries via differential dataflow, and supports instant optimistic mutations with automatic rollback.

Framework packages (@tanstack/react-db, @tanstack/vue-db, @tanstack/svelte-db, @tanstack/solid-db) re-export everything from @tanstack/db plus framework-specific hooks. In framework projects, import from the framework package directly. @tanstack/angular-db is the exception -- import operators from separately.
