What types of testing does this skill facilitate?

It provides checklists and requirements for unit tests, integration tests with mocked APIs, E2E user flows, and visual regression testing.

How does it handle state management?

It guides the implementation of clean state management patterns, preventing prop drilling and state duplication while ensuring robust error boundaries.

How does this skill improve web accessibility?

The skill enforces semantic HTML, ARIA labels, keyboard navigation support, and WCAG 2.1 compliance to ensure interfaces are usable by everyone.

Can this skill help with website performance?

Yes, it includes protocols for code splitting, lazy loading, image optimization, and keeping bundle sizes under 500KB to ensure high Lighthouse scores.

Does it support different frontend frameworks?

While framework-agnostic in its principles, the skill is designed to work with any component-based architecture like React, Vue, or Angular.
