ComeOnOliver Husky
Overview
Husky manages Git hooks from package.json. Run linters, formatters, tests, and commit checks automatically before commits and pushes.
Instructions
Step 1: Setup
npm install -D husky lint-staged
npx husky init
Step 2: Pre-commit Hook
# .husky/pre-commit — Run lint-staged before each commit
npx lint-staged
// package.json — lint-staged configuration
{
"lint-staged": {
"*.{ts,tsx}": ["eslint --fix", "prettier --write"],
"*.{css,md,json}": ["prettier --write"]
}
}
Step 3: Pre-push Hook
# .husky/pre-push — Run tests before pushing
npm test
Guidelines
- Husky v9+ uses .husky/ directory with plain shell scripts.
- lint-staged runs linters only on staged files — fast even in large repos.
- Don't run full test suite in pre-commit (too slow); save it for pre-push or CI.
