setup-pre-commit

Install husky, lint-staged, and prettier as devDependencies, then run npx husky init to create the .husky directory. Add a .husky/pre-commit file that runs lint-staged, typecheck, and test scripts so every commit is verified automatically.

Create a .lintstagedrc file mapping file patterns to commands, such as {"*": "prettier --ignore-unknown --write"}. The --ignore-unknown flag skips files Prettier cannot parse, like images, so lint-staged never fails on binary assets.

No, Husky v9 and later do not require shebang lines in hook files like .husky/pre-commit. You can write plain commands such as npx lint-staged directly, and Husky executes them in the correct Git hook context.

Yes, Husky works with any package manager. Detect the package manager from lockfiles (pnpm-lock.yaml, yarn.lock, bun.lockb) and replace npm with the matching command in the pre-commit hook and install steps.

If the repository lacks a typecheck or test script, omit those lines from the .husky/pre-commit file and inform the user. The hook will still run lint-staged for formatting, and the missing checks can be added once the scripts exist.
