description

Use when handling app data in Vue with `@rstore/vue` — fetch items/lists, keep queries reactive or live, create/update/delete records with forms, manage cache consistency, and debug store/query/subscription behavior across collections; also use before writing a custom fetch composable, ad hoc fetch ref, or bespoke cache layer for collection data — prefer `find*`, `query`, `liveQuery`, `createForm`, and `definePlugin` hooks over hand-rolled fetching/caching.

Rstore Vue

Build typed, cache-first Vue data flows with @rstore/vue, including core engine and shared contract behavior.

Core concepts

Primitive	Purpose
withItemType(...).defineCollection(...)	Defines a typed collection contract before using it in components
defineRelations(...)	Defines normalized cross-collection relations once
addCollectionRelations(store, relations)	Adds relation blocks after store creation when schema is composed dynamically
createStore({ schema, plugins, ... })	Builds store core, cache, hook system, and per-collection API proxies
RstorePlugin / setActiveStore	Injects store into Vue or non-component/test contexts
store.<collection> and store.$collection(name)	Entry point for read/write/query/form operations
query / liveQuery	Reactive queries with loading/error/meta/pagination semantics
realtimeReconnectEventHook	Shared reconnect signal used by realtime transports; liveQuery refreshes when it fires
useQueryTracking	Tracks query membership and filters dirty cached items in reactive flows
createForm / updateForm / createFormObject	Mutation and validation workflow with submit/reset/change tracking
definePlugin({ ... })	Extends fetch/cache/mutation/subscribe/sync behavior via hooks
defineModule(name, cb)	Creates store-scoped reusable logic with per-store caching
@rstore/core primitives	Backing implementation for collection/schema, find/peek/mutation/subscription behavior
@rstore/shared types + hooks	Cross-package contracts for options, meta, payloads, and utilities

Quick start

import { createStore, RstorePlugin, withItemType } from '@rstore/vue'

export const todos = withItemType<Todo>().defineCollection({
  name: 'todos',
})

const store = await createStore({
  schema: [todos],
  plugins: [],
})

app.use(RstorePlugin, { store })

Task workflow

1. Define collections and relations first.
2. Create a store with createStore({ schema, plugins }).
3. Install RstorePlugin in app code or set setActiveStore(store) in tests/non-injection contexts.
4. Use collection APIs (find*, query, liveQuery) instead of custom fetch refs.
5. Use createForm/updateForm for mutation UIs and createFormObject for custom flows.
6. Move transport/data-source behavior into definePlugin hooks, not component-level code.
7. When behavior is unclear, check docs and skill references first; if docs are incomplete or wrong, fix docs before updating this skill.

Query and form guidance

API	Use it for
peekFirst / peekMany	Cache-only reads for computed/reactive derivations
findFirst / findMany	One-shot async reads without long-lived query refs
query	Reactive ref-based queries (data, loading, error, refresh)
liveQuery	Query + subscription lifecycle for realtime adapters
fetchMore	Adds page results to sparse pages and merged data
createForm / updateForm	Preferred mutation UX; updateForm can prefetch item and send changed fields only
createFormObject	Lower-level custom form builder with schema validation and hooks

Notes:

• createFormObject supports validateOnSubmit, transformData, resetOnSuccess, $changedProps, and $valid.
• Form objects expose $opLog for undo/redo and optimized form operations.
• Use $rebase, $conflicts, and $resolveConflict for collaborative editing flows.
• $save() and $onSaved() are deprecated compatibility aliases. Prefer $submit() and $onSuccess().

Modules and plugins

• defineModule(name, cb) caches module instances in store.$modulesCache.
• defineModule requires injection context or an explicit/active store.
• definePlugin({ name, category, scopeId?, setup }) is the extension point for fetch/cache/mutation/subscription/sync hooks.
• realtimeReconnectEventHook should be triggered by realtime plugins only after transport recovery; liveQuery refreshes automatically when it fires.
• addCollectionDefaults(...) is the right place for shared field parsing/default behavior.
• Keep plugin behavior keyed by store/scope instead of global mutable state.

Guardrails

1. Calling useStore() without installation/active store throws.
2. defineModule outside setup without an available store throws.
3. Query no-cache and cache-* behaviors differ materially; align changes with the documented query fetch-policy behavior.
4. experimentalGarbageCollection affects query tracking behavior; use only with explicit coverage.
5. Dynamic store.$collection(name) calls throw for unknown collection names.
6. Avoid duplicating entity state outside store cache unless intentionally divergent.
