TanStack DB core concepts: createCollection with queryCollectionOptions, electricCollectionOptions, powerSyncCollectionOptions, rxdbCollectionOptions, trailbaseCollectionOptions, localOnlyCollectionOptions. Live queries via query builder (from, where, join, select, groupBy, orderBy, limit). Optimistic mutations with draft proxy (collection.insert, collection.update, collection.delete). createOptimisticAction, createTransaction, createPacedMutations. Entry point for all TanStack DB skills.

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 @tanstack/db separately.
