使用说明 (SKILL.md)

TanStack Query 数据获取

Purpose

用声明式 server state 管理替代手写 useEffect + loading

Procedure

  1. 判断状态来源:来自服务端且需要缓存、去重、刷新、分页或 mutation 时使用 TanStack Query;纯本地 UI 状态用 useState/store。
  2. 建立 QueryClientProvider,按业务数据新鲜度设置 staleTimegcTime、retry 和窗口聚焦刷新。
  3. 设计稳定 query key:数组结构包含实体、动作和所有影响结果的参数。
  4. API 函数保持纯请求函数,Query hook 负责缓存、select、loading/error/empty 状态。
  5. mutation 成功后 invalidation;需要即时反馈时使用 optimistic update 并在 onError 回滚。

Quick Start

import { useMutation, useQuery, useQueryClient } from "@tanstack/react-query";

export function UserList({ keyword }: { keyword: string }) {
  const query = useQuery({
    queryKey: ["users", "list", { keyword }],
    queryFn: () => getUserList({ keyword, page: 1, pageSize: 20 }),
    select: (response) => response.list,
  });

  if (query.isLoading) return \x3CSkeleton />;
  if (query.isError) return \x3CErrorFallback onRetry={() => query.refetch()} />;
  if (!query.data?.length) return \x3CEmptyState />;

  return query.data.map((user) => \x3CUserRow key={user.id} user={user} />);
}

export function useCreateUser() {
  const queryClient = useQueryClient();
  return useMutation({
    mutationFn: createUser,
    onSuccess: () => queryClient.invalidateQueries({ queryKey: ["users"] }),
  });
}

Detailed References

涉及 QueryClient 默认配置、乐观更新、无限滚动查询、预取、SSR 水合和 API 层整合时,加载 references/query-patterns.md

Constraints

  • 相同数据必须复用相同 query key;参数缺失会造成缓存串读。
  • staleTime 过长会显示旧数据,过短会造成频繁请求。
  • TanStack Query 不管理本地 UI 状态;不要把 modal、输入框值放进 query cache。
  • 乐观更新必须保存快照并在 onError 回滚。
  • Next.js App Router SSR 需要 dehydrate / HydrationBoundary

Expected Output

数据获取层具备 loading/error/empty/data 状态,重复请求自动去重,mutation 后缓存正确失效或回滚,API 层与 UI 层边界清晰。

安全使用建议
This skill is appropriate to install if you want React Query/TanStack Query implementation guidance. It may influence how an agent writes application data-fetching code, including cache invalidation and optimistic updates, so review generated changes for product-specific API behavior and rollback correctness.
能力评估
Purpose & Capability
The artifacts coherently describe implementing and reviewing server-state data fetching with TanStack Query, including query keys, caching, mutations, optimistic updates, infinite queries, prefetching, SSR hydration, and API-layer boundaries.
Instruction Scope
Instructions are scoped to frontend implementation guidance and explicitly exclude local UI state and Service Worker caching; no prompt override, hidden role change, or unrelated agent instruction was found.
Install Mechanism
The package contains SKILL.md, README, metadata, and one reference document; package.json declares no dependencies, lifecycle scripts, executables, or automatic install-time behavior.
Credentials
The skill only provides code examples and design guidance for application code; it does not require filesystem scanning, network credentials, local profiles, secrets, or privileged environment access.
Persistence & Privilege
No background workers, cron jobs, privilege escalation, credential/session handling, or persistence mechanisms are present; cache lifetime examples are normal TanStack Query application behavior.
如何使用
  1. 确保已安装 OpenClaw(本地或 Docker 部署)
  2. 在对话框中输入安装命令:/install fec-data-fetching
  3. 安装完成后,直接呼叫该 Skill 的名称或使用 /fec-data-fetching 触发
  4. 根据 Skill 的参数说明提供必要输入,即可获得结构化输出
