Frequently Asked Questions

What makes a UI component library production-ready?

A production-ready UI library includes accessibility (WCAG 2.1), keyboard navigation, responsive design, dark mode support, TypeScript types, and comprehensive documentation with usage examples.

Should I build my own components or use a library?

Use a library for standard UI patterns (buttons, modals, forms, tables) and build custom components for your unique product features. This approach saves months of development while maintaining design consistency.

Do these libraries work with Tailwind CSS?

Yes. All UI component libraries in this collection are built with or compatible with Tailwind CSS, making customization straightforward through utility classes and CSS variables.
