tanstack-config（tanstack 配置）

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

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

Vite Build Configuration

Basic Setup

// 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

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

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

Build Options

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

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

export default tanstackEslintConfig

Extending the Config

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

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

Publishing

Publish Configuration

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

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

Monorepo Setup (pnpm + Nx)

Workspace Configuration

# pnpm-workspace.yaml
packages:
  - 'packages/*'
  - 'examples/*'

Nx Configuration

// nx.json
{
  "tasksRunnerOptions": {
    "default": {
      "runner": "nx/tasks-runners/default",
      "options": {
        "cacheableOperations": ["build", "lint", "test"]
      }
    }
  },
  "targetDefaults": {
    "build": {
      "dependsOn": ["^build"]
    }
  }
}

Prettier Configuration

// .prettierrc
{
  "semi": false,
  "singleQuote": true,
  "trailingComma": "all",
  "printWidth": 80
}

EditorConfig

# .editorconfig
root = true

[*]
indent_style = space
indent_size = 2
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

Best Practices

1. Use the Vite config for builds - handles ESM/CJS dual output and declarations
2. Use publint-compliant exports in package.json for compatibility
3. Use Changesets for version management in monorepos
4. Set "type": "module" in package.json for ESM-first packages
5. Include both src and dist in files for source map debugging
6. Use Nx caching for faster builds in monorepos
7. Always generate declaration files (.d.ts) for TypeScript consumers
8. Use the ESLint config as a consistent baseline across packages
9. Automate publishing with GitHub Actions and Changesets

Common Pitfalls

• Missing exports field in package.json (breaks modern bundlers)
• Not setting "type": "module" (causes ESM import issues)
• Forgetting declaration files in build output
• Not excluding test files from the build
• Publishing without running publint validation first
• Not configuring moduleResolution: "bundler" in tsconfig
• Inconsistent versioning across monorepo packages (use Changesets linked)
