// 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.
