## What it does

This skill equips your coding agent with 41 guidelines organized into eight prioritized categories for TanStack Query v5. The highest priorities address query key factories and caching parameters, specifically differentiating `staleTime` from `gcTime`. Other sections cover optimistic mutation rollbacks and network waterfall prevention.

Audit tasks run directly via the project CLI. Running `npx -y @pymodel/react-frontend-skills scan --skill tanstack-query` checks the repository for deprecated patterns and links them to rule IDs. Each rule maps to a markdown document in `references/` with side-by-side correct and incorrect code snippets.

Because the guidelines target TanStack Query v5 directly, running the scanner against a v4 codebase will flag valid legacy syntax as invalid.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill tanstack-query -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tanstack-query/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tanstack-query/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill tanstack-query -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tanstack-query/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill tanstack-query -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tanstack-query/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PyModel/react-frontend-skills tanstack-query
```

2. **Manually: put the files in place**
- File: `.github/skills/tanstack-query/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill tanstack-query -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PyModel/react-frontend-skills --path skills/tanstack-query
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tanstack-query/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PyModel/react-frontend-skills --skill tanstack-query -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PyModel/react-frontend-skills/tree/HEAD/skills/tanstack-query/SKILL.md

## When to use it
- eliminate request waterfalls during data fetching
- set up centralized query key factories with type safety
- configure optimistic updates with rollback on mutation errors
- fine-tune staleTime and gcTime cache thresholds

## Example prompts
- Run npx -y @pymodel/react-frontend-skills scan --skill tanstack-query and refactor outdated query hooks
- Build a query key factory for user profile endpoints using the tquery guidelines
- Add optimistic updates to the comment mutation and cancel outgoing queries before writing to cache

# TanStack Query Best Practices

Comprehensive performance optimization guide for TanStack Query v5 applications. Contains 41 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.

## When to Apply

Reference these guidelines when:
- Writing new queries, mutations, or data fetching logic
- Implementing caching strategies (staleTime, gcTime)
- Reviewing code for performance issues or request waterfalls
- Refactoring existing TanStack Query code
- Implementing infinite queries, Suspense, or optimistic updates

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Query Key Structure | CRITICAL | `tquery-` |
| 2 | Caching Configuration | CRITICAL | `cache-` |
| 3 | Mutation Patterns | HIGH | `mutation-` |
| 4 | Prefetching & Waterfalls | HIGH | `prefetch-` |
| 5 | Infinite Queries | MEDIUM | `infinite-` |
| 6 | Suspense Integration | MEDIUM | `suspense-` |
| 7 | Error & Retry Handling | MEDIUM | `error-` |
| 8 | Render Optimization | LOW-MEDIUM | `render-` |

## Quick Reference

### 1. Query Key Structure (CRITICAL)

- `tquery-key-factories` - Use centralized query key factories
- `tquery-hierarchical-keys` - Structure keys from generic to specific
- `tquery-always-arrays` - Always use array query keys
- `tquery-serializable-objects` - Use serializable objects in keys
- `tquery-options-pattern` - Use queryOptions for type-safe sharing
- `tquery-colocate-keys` - Colocate query keys with features

### 2. Caching Configuration (CRITICAL)

- `cache-staletime-gctime` - Understand staleTime vs gcTime
- `cache-global-defaults` - Configure global defaults appropriately
- `cache-placeholder-vs-initial` - Use placeholderData vs initialData correctly
- `cache-invalidation-precision` - Invalidate with precision
- `cache-refetch-triggers` - Control automatic refetch triggers
- `cache-enabled-option` - Use enabled or skipToken for conditional queries

### 3. Mutation Patterns (HIGH)

- `mutation-optimistic-updates` - Implement optimistic updates with rollback
- `mutation-invalidate-onsettled` - Choose invalidation callbacks by mutation contract
- `mutation-cancel-queries` - Cancel queries before optimistic updates
- `mutation-setquerydata` - Use setQueryData for immediate cache updates
- `mutation-avoid-parallel` - Avoid parallel mutations on same data

### 4. Prefetching & Waterfalls (HIGH)

- `prefetch-avoid-waterfalls` - Avoid request waterfalls
- `prefetch-on-hover` - Prefetch on hover for perceived speed
- `prefetch-in-queryfn` - Start follow-up prefetches when keys become known
- `prefetch-server-components` - Prefetch in Server Components
```
