FAQPage Schema
How do I run TypeScript type checks and ESLint linting on my frontend code?▼

Run frontend validation to execute TypeScript type checks and ESLint linting within the frontend/ directory. This verifies type safety and enforces code style consistency based on your project-specific tsconfig.json and ESLint rules.

Why do I need to validate frontend code before merging?▼

Validating frontend code before merging ensures type safety, linting standard adherence, and passing unit tests. It prevents bugs and maintains code consistency by catching potential issues early in the development cycle.

How do I run Vitest unit tests for my web frontend project?▼

Run Vitest unit tests through the frontend validation process to confirm component and utility functionality. It requires adherence to your project-specific Testing Library configurations to ensure test correctness.

Does frontend validation work with my existing project-specific ESLint rules?▼

Yes, frontend validation requires adherence to your project-specific ESLint rules, tsconfig.json, and Testing Library configurations. It operates within the frontend/ directory to address issues in code style consistency.

What is the best way to check frontend code quality for type errors and style issues?▼

The best way to check frontend code quality is running a validation process that executes TypeScript type checks, ESLint linting, and Vitest unit tests together to address type safety, code style consistency, and test correctness.

What are the limitations of validate-frontend when checking code in non-standard directories?▼

Frontend validation is limited to operating within the frontend/ directory. It requires adherence to project-specific tsconfig.json, ESLint rules, and Testing Library configurations, meaning code outside this directory structure is not addressed.
