Installation

bun add -D bun-git-hooks

Usage

Basic Configuration

Create a git-hooks.config.ts (or .js, .mjs, .cjs, .mts, .cts, .json) file in your project root:

export default {
  'pre-commit': 'bun run lint && bun run test',
  'commit-msg': 'bun commitlint --edit $1',
  'pre-push': 'bun run build'
}

Or add to your package.json:

{
  "git-hooks": {
    "pre-commit": "bun run lint && bun run test",
    "commit-msg": "bun commitlint --edit $1",
    "pre-push": "bun run build"
  }
}

CLI Usage

# Install hooks from config
git-hooks

# alternatively, trigger the CLI with bunx
bunx git-hooks
bunx bun-git-hooks

# Use specific config file
git-hooks ./custom-config.ts

# Remove all hooks
git-hooks uninstall

# Enable verbose logging
git-hooks --verbose

Environment Variables

Skip hook installation when needed:

# Skip hook installation
SKIP_INSTALL_GIT_HOOKS=1 bun install

# Set custom environment for hooks
BUN_GIT_HOOKS_RC=/path/to/env git-hooks

Advanced Configuration

export default {
  // Hook commands
  'pre-commit': 'bun run lint && bun run test',
  'commit-msg': 'bun commitlint --edit $1',

  // Preserve specific unused hooks
  'preserveUnused': ['post-merge', 'post-checkout'],

  // Configure multiple hooks
  'pre-push': [
    'bun run build',
    'bun run test:e2e'
  ].join(' && ')
}

Error Handling

The library provides clear error messages:

try {
  await setHooksFromConfig()
}
catch (err) {
  if (err.message.includes('Config was not found')) {
    console.error('Missing configuration file')
  }
  else if (err.message.includes('git root')) {
    console.error('Not a Git repository')
  }
}

TypeScript Support

Full TypeScript support with detailed type definitions:

interface GitHooksConfig {
  'pre-commit'?: string
  'pre-push'?: string
  'commit-msg'?: string
  'post-merge'?: string
  // ... other git hooks
  'preserveUnused'?: Array<string> | boolean
}

// Types are automatically inferred
const config: GitHooksConfig = {
  'pre-commit': 'bun run test',
  'preserveUnused': ['post-checkout']
}
