pre-commit-checks

To run pre-commit checks, you use lint-staged to format and lint staged files, run TypeScript type checks, and execute Vitest unit tests on staged changes to ensure code quality locally.

Your pre-commit hook fails during lint-staged execution due to linting errors, TypeScript type mismatches, or failing Vitest unit tests, which you can resolve using the provided troubleshooting steps and standardized diagnostics.

You automate TypeScript type checking on staged files by configuring pre-commit hooks with lint-staged, catching type errors early to prevent broken commits and flaky CI pipelines.

Yes, you can use Vitest unit tests to validate staged changes locally by integrating them into your pre-commit hooks, ensuring new changes pass tests before being committed to the repository.

The best way to prevent broken commits is to enforce deterministic pre-commit quality checks, including lint-staged formatting, TypeScript type checking, and Vitest unit tests, with clear failure diagnostics.
