Overview

Configure Git hooks to enforce code quality standards, run automated checks, and prevent problematic commits from being pushed to shared repositories.

When to Use

• Pre-commit code quality checks
• Commit message validation
• Preventing secrets in commits
• Running tests before push
• Code formatting enforcement
• Linting configuration
• Team-wide standards enforcement

Quick Start

Minimal working example:

#!/bin/bash
# setup-husky.sh

# Install Husky
npm install husky --save-dev

# Initialize Husky
npx husky install

# Create pre-commit hook
npx husky add .husky/pre-commit "npm run lint"

# Create commit-msg hook
npx husky add .husky/commit-msg 'npx --no -- commitlint --edit "$1"'

# Create pre-push hook
npx husky add .husky/pre-push "npm run test"

# Create post-merge hook
npx husky add .husky/post-merge "npm install"

Best Practices

✅ DO

• Enforce pre-commit linting and formatting
• Validate commit message format
• Scan for secrets before commit
• Run tests on pre-push
• Skip hooks only with --no-verify (rarely)
• Document hook requirements in README
• Use consistent hook configuration
• Make hooks fast (< 5 seconds)
• Provide helpful error messages
• Allow developers to bypass with clear warnings

❌ DON'T

• Skip checks with --no-verify
• Store secrets in committed files
• Use inconsistent implementations
• Ignore hook errors
• Run full test suite on pre-commit
