Component Generator
Generates production-ready React components from natural language descriptions, including TypeScript types, styling, and tests.
What This Command Does
Component Generation:
- Creates React component with TypeScript
- Generates prop types and interfaces
- Adds basic styling (CSS modules or Tailwind)
- Creates test file (React Testing Library)
- Includes JSDoc comments
- Follows React best practices
Output: Complete component with types, styles, and tests
Time: 2-5 minutes
