What it does

Data Client Vue is an agent skill from reactive/data-client. Use @data-client/vue composables for data fetching, mutations, and rendering - useSuspense, useFetch, useQuery, useCache, useLive, useDLE, useSubscription, useController, useLoading, useDebounce, DataClientPlugin, Suspense, onErrorCaptured. Use when reading/rendering remote data, triggering mutations, doing optimistic updates, real-time subscriptions, or wiring Suspense and error handling in Vue 3.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 28 other files, including reference files (for example `evals/evals.json`, `references.json` and `references/Actions.md`).

It sits in Development, covering Error handling. It works with Vue.js. The repository describes itself as: Async State Management without the Management. REST, GraphQL, SSE, Websockets. The licence is Apache-2.0.

When your agent uses it

  • Reading/rendering remote data
  • Triggering mutations
  • Doing optimistic updates
  • Real-time subscriptions

Example prompts

  • “/data-client-vue”

What it can do on your machine

Read from SKILL.md and the folder at commit 02c0932. 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

    Hosts in commands or code, which the agent is likely to contact:

    • jsonplaceholder.typicode.com

    Also links to:

    • vuejs.org
    • dataclient.io

    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

Data Client Vue loads about 2.5k tokens when it runs, and up to ~38k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 627 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~38k

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.

Setup

Install DataClientPlugin once with app.use(DataClientPlugin) (installation; apply the skill "data-client-setup" to set it up). Composables only work inside <script setup> of components below it. Awaiting composables (await useSuspense()) requires <script setup>: in a hand-written async setup(), composables called after the first await lose the component instance.

Rendering

ts
// GET https://jsonplaceholder.typicode.com/todos/5
const todo = await useSuspense(TodoResource.get, { id: 5 });
// GET https://jsonplaceholder.typicode.com/todos
const todoList = await useSuspense(TodoResource.getList);
// GET https://jsonplaceholder.typicode.com/todos?userId=1
const todoListByUser = await useSuspense(TodoResource.getList, { userId: 1 });
// subscriptions with polling, websockets or SSE
const todo = await useLive(TodoResource.get, { id: 5 });
// without fetch (not awaited)
const todo = useCache(TodoResource.get, { id: 5 });
const todo = useQuery(Todo, { id: 5 });
// fetch without Suspense - returns { data, loading, error } refs
const { data, loading, error } = useDLE(TodoResource.get, { id: 5 });
// subscribe without Suspense (use with useSuspense or useDLE)
useSubscription(TodoResource.get, { id: 5 });
// parallel fetches: start both, then await
useFetch(PostResource.get, { id });
useFetch(CommentResource.getList, { postId: id });
const post = await useSuspense(PostResource.get, { id });
const comments = await useSuspense(CommentResource.getList, { postId: id });
// conditional: null skips fetching and binding
const user = await useSuspense(UserResource.get, () => (userId.value ? { id: userId.value } : null));

For API definitions (like TodoResource), apply the skill "data-client-rest".

Return values are refs
  • useSuspense() and useLive() return a Promise of a readonly ComputedRef: await them at the top level of <script setup>. useCache(), useQuery(), and each of useDLE()'s data/loading/error are ComputedRefs.
  • Templates unwrap them ({{ todo.title }}); in script read .value (todo.value.title).
Reactive arguments

A plain object like { id: props.id } is read once and won't follow prop or route changes. When an argument can change, pass a getter (or a ref/computed) (arguments):

ts
const props = defineProps<{ id: number }>();
// refetches when props.id changes
const todo = await useSuspense(TodoResource.get, () => ({ id: props.id }));

When arguments change, useSuspense() and useLive() keep the previous data until the new fetch resolves (no v-if guard needed); a failed fetch for the new arguments reaches onErrorCaptured().

Mutations

ts
const ctrl = useController();
// PUT https://jsonplaceholder.typicode.com/todos/5
const updateTodo = todo => ctrl.fetch(TodoResource.update, { id }, todo);
// PATCH https://jsonplaceholder.typicode.com/todos/5
const partialUpdateTodo = todo =>
  ctrl.fetch(TodoResource.partialUpdate, { id }, todo);
// POST https://jsonplaceholder.typicode.com/todos
const addTodoToBeginning = todo =>
  ctrl.fetch(TodoResource.getList.unshift, todo);
// POST https://jsonplaceholder.typicode.com/todos?userId=1
const addTodoToEnd = todo => ctrl.fetch(TodoResource.getList.push, { userId: 1 }, todo);
// DELETE https://jsonplaceholder.typicode.com/todos/5
const deleteTodo = id => ctrl.fetch(TodoResource.delete, { id });
// GET https://jsonplaceholder.typicode.com/todos?userId=1&page=2
const getNextPage = (page) => ctrl.fetch(TodoResource.getList.getPage, { userId: 1, page })

Read reactive values (props.todo.id, title.value) inside the handler so each call uses current state. The Controller is also available as $dataClient in any template (and this.$dataClient in the Options API).

Helpful composables

ts
const ctrl = useController();
const [handleSubmit, loading, error] = useLoading(async (data: FormData) => {
  const post = await ctrl.fetch(PostResource.getList.push, data);
  router.push(`/posts/${post.id}`);
});
// loading and error are refs
ts
const query = ref(''); // bound with v-model
const [debouncedQuery, isPending] = useDebounce(query, 200);
// pass debouncedQuery to the component that fetches, inside <Suspense>

Loading and error boundaries

There is no AsyncBoundary component in Vue. A component that awaits useSuspense() or useLive() must render inside Vue's <Suspense>; its #fallback slot is the loading state. Catch fetch errors in an ancestor with onErrorCaptured(). Reuse the codebase's existing boundary component if it has one; otherwise follow the boundary example (onErrorCaptured stores the error and returns false; the template shows it or renders <Suspense>). Place boundaries around route views or sections, not around each data-bound component (boundaries).

Type-safe imperative actions

Controller is returned from useController(). It has: ctrl.fetch(), ctrl.fetchIfStale(), ctrl.expireAll(), ctrl.invalidate(), ctrl.invalidateAll(), ctrl.setResponse(), ctrl.set(), ctrl.setError(), ctrl.resetEntireStore(), ctrl.subscribe(), ctrl.unsubscribe().

Write many entities without a fetch with one ctrl.set([Entity], rows). Never loop ctrl.set(Entity, args, row) per row, and never add an endpoint or setResponse() just to batch.

Programmatic queries

ts
const queryRemainingTodos = new Query(
  TodoResource.getList.schema,
  entries => entries.filter(todo => !todo.completed).length,
);

const allRemainingTodos = useQuery(queryRemainingTodos);
const firstUserRemainingTodos = useQuery(queryRemainingTodos, { userId: 1 });
ts
const groupTodoByUser = new Query(
  TodoResource.getList.schema,
  todos => Object.groupBy(todos, todo => todo.userId),
);
const todosByUser = useQuery(groupTodoByUser);

Browser Debugging (Chrome DevTools MCP)

To inspect store state, track dispatched actions, or invoke Controller methods from a browser MCP (user-chrome-devtools), see devtools-debugging. Uses globalThis.__DC_CONTROLLERS__ available in dev mode.

Managers

Custom Managers allow for global side effect handling. This is useful for websockets, SSE, logging, etc. Pass them to DataClientPlugin with getDefaultManagers. Always use the skill "data-client-manager" when writing managers.

Best Practices & Notes

  • useDebounce(query, timeout) when rendering async data based on user field inputs
  • [handleSubmit, loading, error] = useLoading() when tracking async mutations
  • Prefer smaller Vue components that do one thing
  • Co-locate data bindings: call useSuspense/useDLE/useCache/useQuery in the component that renders the data — don't prop drill
  • Don't hide data bindings inside custom composables: wrapping them obfuscates a component's data dependencies and couples data logic to view code, causing drift. Put tightly coupled data transformations in a Query schema (with the data model, e.g. src/resources/) so they stay reusable and evolve independently of views
  • Don't copy results into ref()/reactive() state; render the returned refs directly so updates flow through
  • For tests, apply the skill "data-client-vue-testing"

References

For detailed API documentation, see the references directory:

ALWAYS follow these patterns and refer to the official docs for edge cases. Prioritize code generation that is idiomatic, type-safe, and leverages automatic normalization/caching via skill "data-client-schema" definitions.
