History
db-core/collection-setup
sub-skill
Creating typed collections with createCollection. Adapter selection: queryCollectionOptions (REST/TanStack Query), electricCollectionOptions (ElectricSQL real-time sync), powerSyncCollectionOptions (PowerSync SQLite), rxdbCollectionOptions (RxDB), trailBaseCollectionOptions (TrailBase), localOnlyCollectionOptions, localStorageCollectionOptions. CollectionConfig options: getKey, schema, sync, gcTime, autoIndex (default off), defaultIndexType, syncMode (eager/on-demand, plus progressive for Electric). StandardSchema validation with Zod/Valibot/ArkType. Collection lifecycle (idle/loading/ready/error). Adapter-specific sync patterns including Electric txid tracking, Query direct writes, Query initial data and scoped factories, and PowerSync query-driven sync with onLoad/onLoadSubset hooks.
466 lines
db-core/custom-adapter
sub-skill
Building custom collection adapters for new backends. SyncConfig interface: sync function receiving begin, write, commit, markReady, markError, truncate, metadata primitives and returning cleanup, loadSubset, and optional unloadSubset handlers. ChangeMessage format (insert, update, delete). On-demand LoadSubsetOptions (where, orderBy, limit, offset, cursor). Expression parsing: parseWhereExpression, parseOrderByExpression, extractSimpleComparisons, parseLoadSubsetOptions. Collection options creator pattern. rowUpdateMode (partial vs full). Sync run, subscription lifecycle, and cleanup functions. Persisted sync metadata API (metadata.row and metadata.collection) for storing per-row and per-collection adapter state.

db-core/live-queries
sub-skill
Query builder fluent API: from, where, join, leftJoin, rightJoin, innerJoin, fullJoin, select, fn.select, groupBy, having, orderBy, limit, offset, distinct, findOne. Operators: eq, gt, gte, lt, lte, like, ilike, inArray, isNull, isUndefined, and, or, not. Aggregates: count, sum, avg, min, max. String functions: upper, lower, length, concat. Utility: coalesce, caseWhen. Math: add, subtract, multiply, divide. $selected namespace. createLiveQueryCollection. Derived collections. Predicate push-down. Incremental view maintenance via differential dataflow (d2ts). Virtual properties ($hasPendingWrites, $origin, $key, $collectionId). Includes subqueries for hierarchical data. Collection, toArray, materialize, and concat(toArray(...)) include modes. queryOnce for one-shot queries. createEffect for reactive side effects (onEnter, onUpdate, onExit, onBatch).
596 lines
db-core/mutations-optimistic
sub-skill
collection.insert, collection.update (Immer-style draft proxy), collection.delete. createOptimisticAction (onMutate + mutationFn). createPacedMutations with debounceStrategy, throttleStrategy, queueStrategy. createTransaction, getActiveTransaction, ambient transaction context. Transaction lifecycle (pending/persisting/completed/failed). Mutation merging. onInsert/onUpdate/onDelete handlers. PendingMutation type. Transaction.isPersisted.
396 lines
db-core/persistence
sub-skill
SQLite-backed persistence for TanStack DB collections. persistedCollectionOptions wraps any adapter (Electric, Query, PowerSync, or local-only) with durable local storage. Platform adapters: browser (WA-SQLite OPFS), React Native (op-sqlite), Expo (expo-sqlite), Electron (IPC), Node (better-sqlite3), Capacitor, Tauri, Cloudflare Durable Objects. Multi-tab/multi-process coordination via BrowserCollectionCoordinator / ElectronCollectionCoordinator / SingleProcessCoordinator. schemaVersion for migration resets. Local-only mode for offline-first without a server. Applied transaction log pruning and safe full-reload recovery.
297 lines
db-core
core
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.
64 lines
meta-framework
composition
Integrating TanStack DB with meta-frameworks (TanStack Start, Next.js, Remix, Nuxt, SvelteKit). Client-side only: SSR is NOT supported — routes must disable SSR. Preloading eager collections in route loaders with collection.preload(). On-demand Query Collections require preloading the live query because source collection preload is a no-op. Multiple collection preloading with Promise.all. Framework-specific loader APIs.
