Git Hooks
Automate code quality with Git hooks using pre-commit, Husky, or native hooks.
Husky + lint-staged (Node.js Projects)
Setup
# Install
npm install -D husky lint-staged
# Initialize husky
npx husky init
# This creates .husky/pre-commit
Configure lint-staged
// package.json
{
"lint-staged": {
"*.{js,jsx,ts,tsx}": [
"eslint --fix",
"prettier --write"
],
"*.{json,md,yml}": "prettier --write",
"*.css": ["stylelint --fix", "prettier --write"]
}
}
Pre-commit Hook
# .husky/pre-commit
npx lint-staged
Pre-push Hook
# Create hook
echo "npm test" > .husky/pre-push
chmod +x .husky/pre-push
Pre-commit Framework (Python/Polyglot)
Setup
pip install pre-commit
pre-commit install

├── pre-commit # Before commit

Simple Pre-commit
#!/bin/sh
# .git/hooks/pre-commit
# Run linter
npm run lint
if [ $? -ne 0 ]; then
echo "Lint failed. Commit aborted."
exit 1
fi
# Run tests
npm test
if [ $? -ne 0 ]; then
echo "Tests failed. Commit aborted."
exit 1
fi
Commit Message Validation
#!/bin/sh
# .git/hooks/commit-msg
commit_msg=$(cat "$1")
# Conventional commits pattern
pattern="^(feat|fix|docs|style|refactor|test|chore)(\(.+\))?: .{1,50}"
if ! echo "$commit_msg" | grep -qE "$pattern"; then
echo "Invalid commit message format."
echo "Use: type(scope): description"
exit 1
fi
Sharing Hooks
Git Config (core.hooksPath)
# Store hooks in repo
mkdir .githooks
mv .git/hooks/* .githooks/
# Configure git to use them
git config core.hooksPath .githooks
Team Setup
// package.json
{
"scripts": {
"prepare": "husky || true"
}
}
Skip Hooks (Emergency)
git commit --no-verify -m "Emergency fix"
git push --no-verify
