Git Hooks Setup

Set up pre-commit, pre-push, and commit-msg hooks

Set up pre-commit, pre-push, and commit-msg git hooks.

Instructions

1. Install Husky:

npm install -D husky lint-staged
npx husky init

2. Set up pre-commit hook (lint + format staged files):

echo "npx lint-staged" > .husky/pre-commit

3. Configure lint-staged in package.json:

{
  "lint-staged": {
    "*.{ts,tsx}": ["eslint --fix", "prettier --write"],
    "*.{json,md,css}": ["prettier --write"]
  }
}

4. Set up commit-msg hook (enforce conventional commits):

npm install -D @commitlint/cli @commitlint/config-conventional
echo "npx --no -- commitlint --edit \$1" > .husky/commit-msg
echo "module.exports = { extends: ['@commitlint/config-conventional'] }" > commitlint.config.js

5. Set up pre-push hook (run tests before pushing):

echo "npm test" > .husky/pre-push

Verify

git add . && git commit -m "test: invalid commit"  # should fail
git commit -m "test: add hook validation"           # should pass
