## Core Concepts
### 1. Design Token Hierarchy
Brand Tokens (abstract)
└── Semantic Tokens (purpose)
└── Component Tokens (specific)
Example:
oklch(45% 0.2 260) → --color-primary → bg-primary
### 2. Component Architecture
Base styles → Variants → Sizes → States → Overrides
## Patterns
### Pattern 1: CVA (Class Variance Authority) Components
// components/ui/button.tsx
import { Slot } from '@radix-ui/react-slot'
import { cva, type VariantProps } from 'class-variance-authority'
import { cn } from '@/lib/utils'
const buttonVariants = cva(
// Base styles - v4 uses native CSS variables
'inline-flex items-center justify-center whitespace-nowrap rounded-md text-sm font-medium transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:pointer-events-none disabled:opacity-50',
{
variants: {
variant: {
default: 'bg-primary text-primary-foreground hover:bg-primary/90',
destructive: 'bg-destructive text-destructive-foreground hover:bg-destructive/90',
outline: 'border border-border bg-background hover:bg-accent hover:text-accent-foreground',
secondary: 'bg-secondary text-secondary-foreground hover:bg-secondary/80',
ghost: 'hover:bg-accent hover:text-accent-foreground',
link: 'text-primary underline-offset-4 hover:underline',
},
size: {
default: 'h-10 px-4 py-2',
sm: 'h-9 rounded-md px-3',
lg: 'h-11 rounded-md px-8',
icon: 'size-10',
},
},
defaultVariants: {
variant: 'default',
size: 'default',
},
}
)
export interface ButtonProps
extends React.ButtonHTMLAttributes<HTMLButtonElement>,
VariantProps<typeof buttonVariants> {
asChild?: boolean
}
// React 19: No forwardRef needed
export function Button({
className,
variant,
size,
asChild = false,
ref,
...props
}: ButtonProps & { ref?: React.Ref<HTMLButtonElement> }) {
const Comp = asChild ? Slot : 'button'
return (
<Comp
className={cn(buttonVariants({ variant, size, className }))}
ref={ref}
{...props}
/>
)
}
// Usage
<Button variant="destructive" size="lg">Delete</Button>
<Button variant="outline">Cancel</Button>
<Button asChild><Link href="/home">Home</Link></Button>
### Pattern 2: Compound Components (React 19)
// components/ui/card.tsx
import { cn } from '@/lib/utils'
// React 19: ref is a regular prop, no forwardRef
export function Card({
className,
ref,
...props
}: React.HTMLAttributes<HTMLDivElement> & { ref?: React.Ref<HTMLDivElement> }) {
return (
<div
ref={ref}
className={cn(
'rounded-lg border border-border bg-card text-card-foreground shadow-sm',
className
)}
{...props}
/>
)
}
export function CardHeader({
className,
ref,
...props
}: React.HTMLAttributes<HTMLDivElement> & { ref?: React.Ref<HTMLDivElement> }) {
return (
<div
ref={ref}
className={cn('flex flex-col space-y-1.5 p-6', className)}
{...props}
/>
)
}
export function CardTitle({
className,
ref,
...props
}: React.HTMLAttributes<HTMLHeadingElement> & { ref?: React.Ref<HTMLHeadingElement> }) {
return (
<h3
ref={ref}
className={cn('text-2xl font-semibold leading-none tracking-tight', className)}
{...props}
/>
)
}
export function CardDescription({
className
