What it does

Tanstack Vue Store Skilld is an agent skill from skilld-dev/vue-ecosystem-skills. Vue adapter for TanStack Store, a framework agnostic type-safe store. ALWAYS use when writing code importing "@tanstack/vue-store" in a Vue app. Covers the useSelector, useAtom, useStore (deprecated), and useStore hooks, the re-exported @tanstack/store core API (createStore, createAtom, createAsyncAtom, batch, flush, shallow), debugging, best practices, and migration between @tanstack/vue-store versions.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/core-api.md`, `references/migration.md` and `references/patterns.md`).

It sits in Development, covering Type safety. It works with TanStack and Vue.js. The repository describes itself as: Agent Skills for the Vue ecosystem, written from current docs, issues, and releases. The licence is MIT.

When your agent uses it

  • Writing code importing @tanstack/vue-store in a Vue app
  • Tasks that involve Type safety

Example prompts

  • “@tanstack/vue-store”
  • “/tanstack-vue-store-skilld”

What it can do on your machine

Read from SKILL.md and the folder at commit c8994af. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • tanstack.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tanstack Vue Store Skilld loads about 1.7k tokens when it runs, and up to ~5.7k if it reads all its reference files. Until then it costs about 109 tokens; SKILL.md has 604 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~109
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Vue adapter for TanStack Store, a framework agnostic type-safe store. ALWAYS use when writing code importing "@tanstack/vue-store" in a Vue app. Covers the useSelector, useAtom, useStore (deprecated), and _useStore hooks, the re-exported @tanstack/store core API (createStore, createAtom, createAsyncAtom, batch, flush, shallow), debugging, best practices, and migration between @tanstack/vue-store versions.

@tanstack/vue-store@0.11.1

Vue adapter for TanStack Store. Exact core dependency: @tanstack/store@0.11.1 (package.json:41). src/index.ts:1 re-exports the whole core, so Vue apps import everything from @tanstack/vue-store alone.

Quick start

ts
import { createStore, createAtom, shallow, useAtom, useSelector } from '@tanstack/vue-store'

// Module scope: create once, import anywhere
const counter = createStore({ count: 0 })
const countAtom = createAtom(0)

// Inside <script setup>
const count = useSelector(counter, (s) => s.count)                             // slice
const pair = useSelector(counter, (s) => ({ n: s.count }), { compare: shallow }) // object slice
const [n, setN] = useAtom(countAtom)                                           // read + write
setN((prev) => prev + 1)

Read refs in templates as {{ count }}, in script as count.value.

Hooks (this package's own exports)

HookSignatureUse
useSelector(source, selector?, options?) => Readonly<Ref<TSelected>>Primary read hook. Store, atom, or any { get, subscribe } source. Omit the selector to subscribe to the whole value.
useAtom(atom, options?) => [Readonly<Ref<TValue>>, atom.set]Read plus write for one writable atom. The setter takes a value or an updater function (src/useAtom.ts:20-27).
_useStore(store, selector, options?) => [selected, actions or setState]Experimental read+write tuple. The selector argument is required (src/_useStore.ts:30). Returns store.actions when the store has an actions factory, else store.setState (src/_useStore.ts:37-38).
useStoredeprecatedAlias for useSelector. Third argument is a bare compare function, not an options object (src/useStore.ts:14-23). Prefer useSelector.

options is UseSelectorOptions: { compare?: (a, b) => boolean } (src/useSelector.ts:4-6).

Details, behavior notes, and pitfalls: Vue hooks reference

Rules that prevent bugs

  • Default compare is strict === (src/useSelector.ts:15-17). When the selector builds a fresh object or array, pass { compare: shallow } or the ref updates on every notification. Primitive selectors need no custom compare.
  • Call the hooks inside component setup or another effect scope. useSelector unsubscribes via onScopeDispose (src/useSelector.ts:54-56); outside a scope, cleanup never runs.
  • Returned refs are readonly. Write through store.setState, atom.set, store actions, or the second tuple element of useAtom/_useStore.
  • Keep selectors cheap. The selector runs on every notification of the source (src/useSelector.ts:46-52); move expensive computation into a derived createStore.
  • Do not import createStoreContext from this package. The 0.11.0 release notes list it, but the 0.11.1 source exports only useSelector, useAtom, useStore, _useStore plus the core re-export (src/index.ts, dist/index.d.ts). See release 0.11.0.

Core re-exports from @tanstack/store

  • createStore(initialValue) -> Store<T>; createStore((prev?) => T) -> ReadonlyStore<T> (derived); createStore(initialValue, actionsFactory) -> Store<T, TActions> with typed store.actions.
  • Store: state getter, get(), setState(updater), subscribe(observerOrFn) returning { unsubscribe }, bound actions. ReadonlyStore omits setState and actions.
  • createAtom(initialValue) -> writable Atom<T>; createAtom(fn) -> computed ReadonlyAtom<T>. AtomOptions.compare controls change detection.
  • createAsyncAtom(() => Promise<T>) -> ReadonlyAtom of a { status } discriminated union: 'pending' | 'done' | 'error'.
  • batch(fn) groups updates into one notification cycle; flush() drains pending effects. shallow(a, b) compares Object.is, then Map and Set contents, Date timestamps, and own keys including symbols.
  • toObserver() normalizes callbacks or RxJS-style observers for subscribe.
  • Types: Observer, Subscription, Subscribable, Readable, Atom, ReadonlyAtom, AtomOptions, StoreActionMap, StoreActionsFactory, and others.

Best practices

  • Use useSelector, never the deprecated useStore, for new code (src/useSelector.ts:39).
  • Define stores in plain modules outside components. This is the documented sharing pattern (Vue quick start).
  • Select fine-grained slices. The component re-renders only when the selected value changes.
  • Write state through store.setState((prev) => next) updater functions; updates are immutable.
  • Group multiple updates in batch(() => { ... }) so subscribers notify once with the final state.
  • Derive with createStore(() => ...); derived stores recompute when dependencies change, and prev accumulates values.
  • Co-locate writes with an actions factory so _useStore returns typed actions (src/_useStore.ts:37-38).
  • Use createAsyncAtom for async data instead of hand-rolled pending and error flags.
  • Observe state outside components with store.subscribe(() => ...); it returns { unsubscribe }.

Migration

Version-specific changes and upgrade steps, most recent first: migration reference

Highlights:

  • 0.11.x: useSelector introduced as primary hook; useStore deprecated; default compare is ===, replacing the pre-0.11 shallow default and { equal } option.
  • 0.9.0 breaking: new Store() -> createStore(); new Derived() -> derived createStore(fn); new Effect() removed in favor of store.subscribe().

Environment

  • Vue ^3.0.0 or ^2.5.0 through vue-demi. Vue 2 needs the optional peer @vue/composition-api@^1.2.1 (package.json:50-58).
  • Exact core pin @tanstack/store@0.11.1; core APIs are re-exported, so no separate core install is needed in Vue apps.
  • Dual format: ESM via the import condition (dist/index.js), CJS via require (dist/index.cjs); types at dist/index.d.cts; sideEffects: false.
  • TypeScript 5.6 through 5.9 are tested (package.json:62-66).
