Overview

Build scalable, maintainable React components using modern patterns including functional components, hooks, composition, and TypeScript for type safety.

When to Use

• Component library design
• Large-scale React applications
• Reusable UI patterns
• Custom hooks development
• Performance optimization

Quick Start

Minimal working example:

// Button.tsx
import React, { useState, useCallback } from 'react';

interface ButtonProps {
  variant?: 'primary' | 'secondary' | 'danger';
  size?: 'sm' | 'md' | 'lg';
  disabled?: boolean;
  onClick?: () => void;
  children: React.ReactNode;
}

export const Button: React.FC<ButtonProps> = ({
  variant = 'primary',
  size = 'md',
  disabled = false,
  onClick,
  children
}) => {
  const variantStyles = {
    primary: 'bg-blue-500 hover:bg-blue-600',
    secondary: 'bg-gray-500 hover:bg-gray-600',
    danger: 'bg-red-500 hover:bg-red-600'
  };

  const sizeStyles = {
// ... (see reference guides for full implementation)
