code-quality-gate

To set up pre-commit hooks for TypeScript checks and linting, install husky and lint-staged, initialize husky, and configure pre-commit to run lint-staged with your TypeScript compilation and formatting steps to catch errors locally before commits.

A multi-stage quality gate pipeline prevents production failures by enforcing automated checks across five stages: local pre-commit hooks, CI PR-checks, preview deployments, E2E tests, and a final production gate that only proceeds if all prior checks pass.

Yes, you can use a GitHub Actions workflow to run unit tests and TypeScript builds on pull requests, blocking merges when failures occur. You must avoid using continue-on-error in your TypeScript checks to ensure the pipeline strictly blocks failures.

Yes, the automated quality gate workflow supports running Playwright-based E2E tests and Lighthouse performance audits on Vercel or Netlify preview deployment URLs to verify application behavior and performance before reaching production.

The best way to handle failed production deployments is to implement a rollback option within your deployment gate, ensuring that if issues slip past CI checks and E2E tests, the system can automatically revert the production environment to a stable state.

Pre-commit hooks catch formatting and TypeScript compilation errors locally before code is pushed, while CI quality gates run broader unit tests and build steps on GitHub Actions, together preventing faulty code from merging or deploying to production.
