code-quality-management

Automated code quality checks combine formatting, linting, type checking, and testing. Install Biome for formatting, ESLint for React and TypeScript rules, configure TypeScript for type safety, set up Vitest for unit tests and Playwright for end-to-end tests, then orchestrate them through package.json scripts and Husky pre-commit hooks to enforce standards before code is committed.

Biome handles formatting and basic linting as a unified tool, while ESLint provides deeper rule customization for React and TypeScript-specific patterns. Using both together—Biome for consistency and ESLint for complex rules—creates a comprehensive quality gate that catches more issues than either alone.

Configure package.json scripts for lint, type-check, test, and end-to-end tests, then add them to your CI pipeline. Husky pre-commit hooks with lint-staged run checks locally before commit, ensuring only code meeting all quality standards reaches CI and prevents merge until tests pass.

Yes. Vitest runs unit tests for individual functions and components, while Playwright runs end-to-end tests across the full application workflow. Together they provide both fast isolated testing and real-world user-flow validation as part of your quality gate pipeline.

Yes. While Biome handles formatting and basic linting, ESLint adds React and TypeScript-specific rule enforcement that Biome doesn't cover. Configure both to work alongside each other, with Biome running first for consistency and ESLint catching deeper pattern violations.

Yes. Lint-fix workflows automatically correct formatting and common linting violations before commit. Husky with lint-staged applies fixes locally, and you can configure scripts to run fix commands as part of your development workflow, reducing manual corrections.
