Component Toolkit

Reinventing the wheel is a productivity killer. This toolkit exists because hunting for reliable UI components and code snippets across random GitHub repos wastes valuable development time. You need battle-tested components, proven code patterns, and copy-paste solutions that actually work—not broken examples from outdated tutorials.

Quick Reference - Must-Have Libraries

1. shadcn/ui - Copy-paste components with Tailwind CSS, visual builder

2. Ant Design - Enterprise-grade components with 91.5k GitHub stars

3. 30 Seconds of Code - 1,078+ short snippets for common development needs

4. CodePen - Live code playground with community-driven examples

5. Material UI - AI-assisted theming with advanced customization

Rules & Standards

Code Quality Standards

‍All components must be production-ready, not proof-of-concepts. Code should be clean, commented, and follow framework conventions. Include proper TypeScript types where applicable. Test components across different browsers and devices before adding to your toolkit.

Documentation Requirements

‍Every component needs clear usage examples, prop definitions, and implementation notes. Include do's and don'ts with visual examples. Document browser support and known limitations. Update documentation immediately when changing components.

Version Control

‍Use semantic versioning for all components. Major version changes indicate breaking changes. Track component dependencies carefully. Document migration paths when updating existing components. Never break backwards compatibility without proper deprecation warnings.

Design System Integration

‍Components must align with your design system's tokens: colors, spacing, typography, and breakpoints. Inconsistent components break user experience. Establish design tokens first, then build components that use them consistently.

Accessibility Standards

‍All components must meet WCAG 2.1 AA standards minimum. Include proper ARIA labels, keyboard navigation, and screen reader support. Test with actual accessibility tools, not just automated checkers. Focus management is crucial for complex components.

Framework Compatibility

‍Choose your primary framework (React, Vue, Angular) and optimize for it. Don't try to support everything—focus on excellence in one framework rather than mediocrity across many. Provide clear installation and setup instructions.

Performance Guidelines

‍Components should be optimized for tree-shaking. Include only necessary dependencies. Keep bundle sizes small—large component libraries slow down applications. Provide both individual component imports and full library options.

Testing Requirements

‍Every component needs unit tests covering props, events, and edge cases. Include visual regression tests for complex components. Test keyboard navigation and screen reader compatibility. Automated testing prevents regressions when updating components.
