What this skill does


# TanStack Query for Next.js

TanStack Query v5 provides powerful server state management with Next.js 16 integration.

## Agent Workflow (MANDATORY)

Before ANY implementation, use `TeamCreate` to spawn 3 agents:

1. **fuse-ai-pilot:explore-codebase** - Analyze existing data fetching patterns
2. **fuse-ai-pilot:research-expert** - Verify latest TanStack Query v5 docs
3. **mcp__context7__query-docs** - Check TanStack Query + Next.js patterns

After implementation, run **fuse-ai-pilot:sniper** for validation.

## Overview

### When to Use

- Client-side data fetching with caching and revalidation
- Server-side prefetching with hydration to client
- Optimistic updates for mutations
- Infinite scrolling and pagination
- Real-time data synchronization

### Why TanStack Query

| Feature | Benefit |
|---------|---------|
| Server prefetching | Data ready on first render, no loading flash |
| Automatic caching | Deduplication, stale-while-revalidate |
| Mutations | Optimistic updates, rollback on error |
| DevTools | Visual cache inspection |
| TypeScript-first | Full type inference |

---

## Critical Rules

1. **One QueryClient per request** - Create in Server Component, share via context
2. **Prefetch in Server Components** - Use `prefetchQuery` for SSR data
3. **HydrationBoundary required** - Wrap client tree to transfer server cache
4. **Query keys must be serializable** - Arrays of strings/numbers only
5. **`staleTime` on prefetched queries** - Prevent immediate refetch on mount
6. **Never use `queryClient` in Client Components directly** - Use hooks

---

## Installation

```bash
bun add @tanstack/react-query @tanstack/react-query-devtools
```

---

## Best Practices

1. **Prefetch on server** - Avoid loading states for critical data
2. **Set `staleTime`** - Prevent unnecessary refetches after hydration
3. **Collocate query keys** - Define keys near their usage
4. **Invalidate on mutation** - Use `invalidateQueries` after writes
5. **Error boundaries** - Use `throwOnError` for critical queries
6. **DevTools in dev only** - Wrap in `process.env.NODE_ENV` check

tanstack-query

Included

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
