## What it does

The skill provides workflow rules for `@tanstack/config`. It teaches coding agents how to build dual ESM and CJS packages with `.d.ts` declaration files using Vite, apply `tanstackEslintConfig`, and structure `package.json` exports to pass publint checks.

It includes templates for pnpm workspaces and Nx task caching. GitHub Actions workflows run on Node 20. Version bumping and changelogs rely on Changesets.

Omitting `moduleResolution: "bundler"` in `tsconfig.json` or skipping test exclusions in the Vite config will break builds for downstream consumers.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tanstack-skills/tanstack-skills --skill tanstack-config -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tanstack-skills/tanstack-skills --skill tanstack-config -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tanstack-skills/tanstack-skills tanstack-config
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/tanstack-skills/tanstack-skills --path plugins/tanstack-config/skills/tanstack-config
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tanstack-skills/tanstack-skills --skill tanstack-config -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/tanstack-skills/tanstack-skills/tree/HEAD/plugins/tanstack-config/skills/tanstack-config/SKILL.md

## When to use it
- configure dual ESM and CJS builds in Vite with generated `.d.ts` files
- define publint-compliant `exports` maps inside `package.json`
- automate package publishing and changelog creation using Changesets
- configure a pnpm monorepo workspace with Nx task caching

## Example prompts
- Configure vite.config.ts with multiple entry points using tanstack-config
- Set up publint-compatible exports in package.json for my TypeScript library
- Create a GitHub Actions publish workflow with Changesets and pnpm

## Overview

TanStack Config provides an opinionated, minimal-configuration toolkit for JavaScript/TypeScript package development. It includes Vite-powered build configuration, ESLint presets, publish automation with semantic versioning, and integrations with TypeScript, Prettier, Changesets, and GitHub Actions. Designed for monorepo workflows with pnpm and Nx.

**Package:** `@tanstack/config`
**Status:** Stable

## Installation

```bash
npm install @tanstack/config --save-dev
# or
pnpm add @tanstack/config -D
```

## Vite Build Configuration

### Basic Setup

```typescript
// vite.config.ts
import { defineConfig, mergeConfig } from 'vitest/config'
import { tanstackViteConfig } from '@tanstack/config/vite'

const config = defineConfig({
  // Your custom Vite config
})

export default mergeConfig(
  config,
  tanstackViteConfig({
    entry: './src/index.ts',
    srcDir: './src',
    exclude: ['./src/__tests__'],
  })
)
```

### Multiple Entry Points

```typescript
import { tanstackViteConfig } from '@tanstack/config/vite'

export default tanstackViteConfig({
  entry: [
    './src/index.ts',
    './src/adapters.ts',
    './src/utils.ts',
  ],
  srcDir: './src',
})
```

### Build Options

```typescript
tanstackViteConfig({
  entry: './src/index.ts',
  srcDir: './src',
  exclude: ['./src/__tests__', './src/**/*.test.ts'],
  // Generates ESM and CJS outputs
  // Generates .d.ts declaration files
  // Handles tree-shaking configuration
})
```

## ESLint Configuration

### Basic Setup

```javascript
// eslint.config.js
import { tanstackEslintConfig } from '@tanstack/config/eslint'

export default tanstackEslintConfig
```

### Extending the Config

```javascript
// eslint.config.js
import { tanstackEslintConfig } from '@tanstack/config/eslint'

export default [
  ...tanstackEslintConfig,
  {
    rules: {
      // Custom overrides
      '@typescript-eslint/no-explicit-any': 'warn',
    },
  },
]
```

## Publishing

### Publish Configuration

```typescript
// publish.config.ts or used via CLI
import { tanstackPublishConfig } from '@tanstack/config/publish'

export default tanstackPublishConfig({
  // Publint-compliant defaults
  // Semantic versioning automation
  // Changelog generation
})
```

### Package.json Setup

```json
{
  "name": "@myorg/my-package",
  "version": "0.0.0",
  "type": "module",
  "main": "dist/cjs/index.cjs",
  "module": "dist/esm/index.js",

    }
  },
  "files": ["dist", "src"],
  "scripts": {
