Design systems are the backbone of consistent user interfaces. Here's how to build one that scales.

## Why Design Systems Matter

A well-crafted design system provides:

- **Consistency** across all products
- **Faster development** with reusable components
- **Better collaboration** between designers and developers
- **Reduced technical debt** over time

## Core Principles

### 1. Start with Tokens

Design tokens are the atomic values of your system:

```typescript title="tokens.ts"
export const tokens = {
  colors: {
    primary: {
      50: '#eff6ff',
      500: '#3b82f6',
      900: '#1e3a8a',
    },
    neutral: {
      0: '#ffffff',
      100: '#f5f5f5',
      900: '#171717',
    },
  },
  spacing: {
    xs: '0.25rem',
    sm: '0.5rem',
    md: '1rem',
    lg: '1.5rem',
    xl: '2rem',
  },
  radii: {
    sm: '0.25rem',
    md: '0.5rem',
    lg: '1rem',
    full: '9999px',
  },
} as const;
```

### 2. Build Primitive Components

Start with the basics:

```tsx title="Button.tsx"
import { cva, type VariantProps } from "class-variance-authority";

const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md font-medium transition-colors",
  {
    variants: {
      variant: {
        primary: "bg-primary text-white hover:bg-primary/90",
        secondary: "bg-secondary text-secondary-foreground hover:bg-secondary/80",
        ghost: "hover:bg-accent hover:text-accent-foreground",
      },
      size: {
        sm: "h-8 px-3 text-sm",
        md: "h-10 px-4",
        lg: "h-12 px-6 text-lg",
      },
    },
    defaultVariants: {
      variant: "primary",
      size: "md",
    },
  }
);

interface ButtonProps
  extends React.ButtonHTMLAttributes<HTMLButtonElement>,
    VariantProps<typeof buttonVariants> {}

export function Button({ variant, size, className, ...props }: ButtonProps) {
  return (
    <button className={buttonVariants({ variant, size, className })} {...props} />
  );
}
```

## Component Composition

Build complex components from primitives:

| Level | Examples | Purpose |
|-------|----------|---------|
| Tokens | Colors, spacing, typography | Foundation |
| Primitives | Button, Input, Badge | Building blocks |
| Patterns | Card, Modal, Dropdown | Common UI patterns |
| Templates | PageHeader, Sidebar | Layout structures |

## Documentation is Key

> "A design system without documentation is just a component library."

Every component should include:

1. **Usage examples** - Show common use cases
2. **Props documentation** - Explain all options
3. **Accessibility notes** - ARIA labels, keyboard nav
4. **Do's and Don'ts** - Guide proper usage

## Versioning Strategy

```json title="package.json"
{
  "name": "@company/design-system",
  "version": "2.1.0",
  "peerDependencies": {
    "react": "^18.0.0",
    "tailwindcss": "^3.0.0"
  }
}
```

Use semantic versioning:
- **Major**: Breaking changes
- **Minor**: New features (backward compatible)
- **Patch**: Bug fixes

## Conclusion

Building a design system is an investment that pays dividends in:

- Developer productivity
- Design consistency
- User experience
- Team collaboration

Start small, iterate often, and document everything.
