---
# Backstage Style Web Generator
## Overview
Create professional, enterprise-grade web applications using the Backstage Design System. This skill generates modern React applications with TypeScript, featuring comprehensive UI components, dark/light theme support, responsive design, and accessibility-first patterns. Perfect for building admin dashboards, developer tools, internal applications, and data management interfaces.
# Backstage Design System Implementation Guide
## Core Architecture Overview
The Backstage Design System is built on modern React patterns and industry-standard libraries:
### Technology Stack
- **React 18+** with TypeScript
- **Radix UI Primitives** for accessible, headless components
- **Tailwind CSS** for utility-first styling
- **Class Variance Authority (CVA)** for type-safe component variants
- **React Hook Form** with Zod validation
- **Lucide React** for consistent iconography
### Key Design Principles
1. **Accessibility First**: Built on Radix UI primitives with ARIA support
2. **Type Safety**: Full TypeScript coverage with strict typing
3. **Composability**: Components designed for flexible composition
4. **Consistency**: Unified design tokens and patterns
5. **Performance**: Optimized for bundle size and runtime performance
## Component Architecture Patterns
### 1. Compound Components
Components are designed with multiple sub-components for maximum flexibility:
```typescript
// Card component structure
<Card>
<CardHeader>
<CardTitle>Title</CardTitle>
<CardDescription>Description</CardDescription>
<CardAction>Action buttons</CardAction>
</CardHeader>
<CardContent>
Main content
</CardContent>
<CardFooter>
Footer content
</CardFooter>
</Card>
```
### 2. Variant-Based Styling
Using CVA for type-safe, predictable component variants:
```typescript
const buttonVariants = cva(
"inline-flex items-center justify-center rounded-md text-sm font-medium",
{
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-input bg-background hover:bg-accent",
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: "h-10 w-10",
},
},
defaultVariants: {
variant: "default",
size: "default",
},
}
);
```
### 3. Data Attributes for Styling
Consistent use of data attributes for component identification and styling:
```typescript
<div
data-slot="card"
className="bg-card text-card-foreground rounded-lg border"
>
<div data-slot="card-header">
{/* Header content */}
</div>
</div>
```
## Theme System Implementation
### 1. Color Architecture
#### Brand Colors (11-step scale)
```css
:root {
--brand-050: #F5F1F0; /* 最浅背景色 */
--brand-100: #E9DDDB; /* Hover background / light tint */
--brand-200: #D6BEBB; /* Soft background */
--brand-300: #B78F8A; /* Subtle brand tint */
--brand-400: #94635E; /* Hover / outline */
--brand-500: #6A4040; /* Primary brand color */
--brand-600: #5B3535; /* Active / pressed */
--brand-700: #4C2D2D; /* Stronger contrast */
--brand-800: #3E2525; /* Deep background */
--brand-900: #2E1C1C; /* Text on light */
--brand-950: #1C1010; /* Text on dark / darkest tone */
}
```
#### Semantic Color Tokens
```css
:root {
/* === Light Mode === */
--background: hsl(48, 33%, 98%);
--foreground: hsl(0, 25%, 33%);
--card: hsl(48, 33%, 98%);
--card-foreground: hsl(0, 25%, 33%);
--popover: hsl(48, 33%, 98%);
--popover-foreground: hsl(0, 25%, 33%);
--primary: hsl(222, 28%, 14%);
--primary-foreground: hsl(48, 33%, 98%);
--secondary: hsl(210, 25%, 96%);
--secondary-foreground: hsl(0, 25%, 33%);
--muted: hsl(210, 25%, 96%);
--muted-foreground: hsl(215, 9%, 46%);
--accent: hsl(210, 25%, 96%);
--accent-foreground: hsl(0, 25%, 33%);
--destructive: hsl(0, 82%, 67%);
--destructive-foreground: hsl(48, 33%, 98%);
--border: hsl(0, 14%, 94%);
--input: hsl(214, 27%, 91%);
--ring: hsl(0, 25%, 33%);
}
[data-theme='dark'] {
/* === Dark Mode === */
--background: hsl(0, 25%, 6%);
--foreground: hsl(48, 33%, 98%);
--card: hsl(0, 25%, 6%);
--card-foreground: hsl(48, 33%, 98%);
--popover: hsl(0, 25%, 6%);
--popover-foreground: hsl(48, 33%, 98%);
--primary: hsl(48, 33%, 98%);
--primary-foreground: hsl(0, 25%, 33%);
--secondary: hsl(0, 22%, 14%);
--secondary-foreground: hsl(48, 33%, 98%);
--muted: hsl(0, 22%, 14%);
--muted-foreground: hsl(0, 20%, 75%);
--accent: hsl(0, 22%, 14%);
--accent-foreground: hsl(48, 33%, 98%);
--destructive: hsl(0, 82%, 67%);
--destructive-foreground: hsl(48, 33%, 98%);
--border: hsl(0, 22%, 14%);
--input: hsl(0, 22%, 14%);
--ring: hsl(0, 25%, 33%);
}
```
### 2. Font Families
```css
/* Import custom fonts */
@font-face {
font-family: 'Instrument Serif';
src: url('./references/InstrumentSerif-Regular.ttf') format('truetype');
font-weight: 400;
font-style: normal;
}
@font-face {
font-family: 'Instrument Serif';
src: url('./references/InstrumentSerif-Italic.ttf') format('truetype');
font-weight: 400;
font-style: italic;
}
/* Typography Rules */
/* Paragraph and text content */
p, .text-body, .text-content {
font-family: 'Poppins', -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif;
}
/* Headings */
h1, h2, h3, h4, h5, h6,
.heading-1, .heading-2, .heading-3, .heading-4, .heading-5, .heading-6 {
font-family: 'Instrument Serif', Georgia, 'Times New Roman', serif;
font-weight: 400;
}
/* Prepositions in headings should use italic */
h1 .preposition, h2 .preposition, h3 .preposition,
h4 .preposition, h5 .preposition, h6 .preposition,
.heading-1 .preposition, .heading-2 .preposition, .heading-3 .preposition,
.heading-4 .preposition, .heading-5 .preposition, .heading-6 .preposition {
font-style: italic;
}
```
### 3. Typography Scale
```css
.text-xxs { font-size: 8px; } /* Micro text */
.text-xs { font-size: 10px; } /* Caption */
.text-sm { font-size: 12px; } /* Secondary text */
.text-base { font-size: 14px; } /* Default body */
.text-lg { font-size: 16px; } /* Paragraph */
.display-xl { font-size: 60px; } /* Hero headings */
```
### 4. Spacing System (4px base unit)
```css
.space-1 { margin: 4px; } /* XS */
.space-2 { margin: 8px; } /* SM */
.space-3 { margin: 12px; } /* MD */
.space-4 { margin: 16px; } /* LG - Component spacing */
.space-6 { margin: 24px; } /* Standard spacing */
.space-8 { margin: 32px; } /* Section padding */
.space-16 { margin: 64px; } /* Large sections */
```
## Responsive Design Strategy
### 1. Breakpoint System
```css
/* Mobile-first approach */
sm: '640px', /* Small devices */
md: '768px', /* Tablets */
lg: '1024px', /* Laptops */
xl: '1280px', /* Desktops */
2xl: '1536px' /* Large screens */
```
### 2. Component Responsiveness
```typescript
// Example: Responsive grid
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
{/* Cards automatically adapt */}
</div>
// Custom mobile hook
const isMobile = useIsMobile(); // 768px breakpoint
```
### 3. Sidebar Adaptation
```typescript
// Desktop: Collapsible sidebar
// Mobile: Transforms to sheet/drawer
{isMobile ? (
<Sheet open={openMobile} onOpenChange={setOpenMobile}>
<SheetContent side="left" className="p-0">
<SidebarContent />
</SheetContent>
</Sheet>
) : (
<Sidebar className={cn(
"transition-all duration-300",
state === "collapsed" ? "w-[48px]" : "w-[256px]"
)}>
<SidebarContent />
</Sidebar>
)}
```
## Accessibility Implementation
### 1. ARIA Patterns
```typescript
// Proper ARIA labeling
<button
aria-label="Close dialog"
aria-expanded={isOpen}
aria-controls="dialog-content"
>
<X className="h-4 w-4" />
</button>
// Form accessibility
<label htmlFor="email" className="sr-only">
Email address
</label>
<input
id="email"
type="email"
aria-describedby="email-description"
aria-invalid={hasError}
/>
<div id="email-description" className="text-sm text-muted-foreground">
We'll never share your email
</div>
```
### 2. Keyboard Navigation
```typescript
// Custom keyboard event handling
useEffect(() => {
const handleKeyDown = (event: KeyboardEvent) => {
if (event.key === 'Escape') {
onClose();
}
if (event.key === 'Enter' || event.key === ' ') {
onActivate();
}
};
document.addEventListener('keydown', handleKeyDown);
return () => document.removeEventListener('keydown', handleKeyDown);
}, [onClose, onActivate]);
```
### 3. Focus Management
```typescript
// Focus trap for modals
import { FocusTrap } from '@radix-ui/react-focus-trap';
<FocusTrap asChild>
<div className="modal-content">
{/* Modal content with proper focus order */}
</div>
</FocusTrap>
```
## Form Architecture
### 1. React Hook Form Integration
```typescript
import { useForm } from "react-hook-form";
import { zodResolver } from "@hookform/resolvers/zod";
import * as z from "zod";
const formSchema = z.object({
email: z.string().email("Invalid email address"),
password: z.string().min(8, "Password must be at least 8 characters"),
});
type FormData = z.infer<typeof formSchema>;
const form = useForm<FormData>({
resolver: zodResolver(formSchema),
defaultValues: {
email: "",
password: "",
},
});
```
### 2. Form Field Component Pattern
```typescript
<FormField
control={form.control}
name="email"
render={({ field }) => (
<FormItem>
<FormLabel>Email</FormLabel>
<FormControl>
<Input placeholder="Enter your email" {...field} />
</FormControl>
<FormDescription>
We'll use this to send you updates
</FormDescription>
<FormMessage />
</FormItem>
)}
/>
```
## State Management Patterns
### 1. Component State
```typescript
// Local state for UI interactions
const [isOpen, setIsOpen] = useState(false);
const [selectedItems, setSelectedItems] = useState<string[]>([]);
// Derived state
const hasSelection = selectedItems.length > 0;
const allSelected = selectedItems.length === items.length;
```
### 2. Context for Shared State
```typescript
// Theme context
const ThemeContext = createContext<{
theme: Theme;
setTheme: (theme: Theme) => void;
} | null>(null);
// Sidebar context
const SidebarContext = createContext<{
state: "expanded" | "collapsed";
open: boolean;
setOpen: (open: boolean) => void;
isMobile: boolean;
} | null>(null);
```
### 3. URL State Management
```typescript
// For filters, search, pagination
const [searchParams, setSearchParams] = useSearchParams();
const currentPage = Number(searchParams.get('page')) || 1;
const searchQuery = searchParams.get('q') || '';
const updateFilters = (filters: Record<string, string>) => {
const newParams = new URLSearchParams(searchParams);
Object.entries(filters).forEach(([key, value]) => {
if (value) {
newParams.set(key, value);
} else {
newParams.delete(key);
}
});
setSearchParams(newParams);
};
```
## Performance Optimization
### 1. Code Splitting
```typescript
// Lazy loading for routes
const Dashboard = lazy(() => import('./pages/Dashboard'));
const Settings = lazy(() => import('./pages/Settings'));
// Wrap in Suspense
<Suspense fallback={<LoadingSpinner />}>
<Routes>
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/settings" element={<Settings />} />
</Routes>
</Suspense>
```
### 2. Memoization
```typescript
// Expensive calculations
const processedData = useMemo(() => {
return data.map(item => ({
...item,
computed: expensiveComputation(item)
}));
}, [data]);
// Callback memoization
const handleItemClick = useCallback((id: string) => {
setSelectedItems(prev =>
prev.includes(id)
? prev.filter(item => item !== id)
: [...prev, id]
);
}, []);
// Component memoization
const MemoizedTableRow = memo(TableRow);
```
### 3. Virtual Scrolling (for large lists)
```typescript
import { FixedSizeList as List } from 'react-window';
const VirtualizedTable = ({ items }: { items: any[] }) => {
const Row = ({ index, style }: { index: number; style: React.CSSProperties }) => (
<div style={style}>
<TableRow data={items[index]} />
</div>
);
return (
<List
height={600}
itemCount={items.length}
itemSize={50}
width="100%"
>
{Row}
</List>
);
};
```
## Testing Patterns
### 1. Component Testing
```typescript
import { render, screen, fireEvent } from '@testing-library/react';
import { Button } from './button';
describe('Button', () => {
it('renders with correct variant styles', () => {
render(<Button variant="destructive">Delete</Button>);
const button = screen.getByRole('button');
expect(button).toHaveClass('bg-destructive');
});
it('handles click events', () => {
const handleClick = jest.fn();
render(<Button onClick={handleClick}>Click me</Button>);
fireEvent.click(screen.getByRole('button'));
expect(handleClick).toHaveBeenCalledTimes(1);
});
});
```
### 2. Accessibility Testing
```typescript
import { axe, toHaveNoViolations } from 'jest-axe';
expect.extend(toHaveNoViolations);
it('should not have accessibility violations', async () => {
const { container } = render(<MyComponent />);
const results = await axe(container);
expect(results).toHaveNoViolations();
});
```
This implementation guide provides the foundation for building consistent, accessible, and performant applications using the Backstage Design System.

## Component Building Blocks
### 1. Data Display Card
```typescript
import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card";
import { Badge } from "@/components/ui/badge";
import { Button } from "@/components/ui/button";
interface DataCardProps {
title: string;
value: string | number;
description?: string;
trend?: "up" | "down" | "neutral";
trendValue?: string;
action?: React.ReactNode;
}
export function DataCard({
title,
value,
description,
trend,
trendValue,
action
}: DataCardProps) {
const trendColor = {
up: "text-green-600",
down: "text-red-600",
neutral: "text-muted-foreground",
};
return (
<Card>
<CardHeader className="flex flex-row items-center justify-between space-y-0 pb-2">
<CardTitle className="text-sm font-medium">{title}</CardTitle>
{action}
</CardHeader>
<CardContent>
<div className="text-2xl font-bold">{value}</div>
{(description || trendValue) && (

</p>
)}
</CardContent>
</Card>
);
}
```
### 2. Action Header
```typescript

interface ActionHeaderProps {
title: string;
description?: string;

import { cva, type VariantProps } from "class-variance-authority";
const statusVariants = cva("", {
variants: {
status: {
active: "bg-green-100 text-green-800 hover:bg-green-100/80",
inactive: "bg-gray-100 text-gray-800 hover:bg-gray-100/80",
pending: "bg-yellow-100 text-yellow-800 hover:bg-yellow-100/80",
error: "bg-red-100 text-red-800 hover:bg-red-100/80",
success: "bg-emerald-100 text-emerald-800 hover:bg-emerald-100/80",
warning: "bg-amber-100 text-amber-800 hover:bg-amber-100/80",
},
},
defaultVariants: {
status: "inactive",
},
});
interface StatusBadgeProps extends VariantProps<typeof statusVariants> {
children: React.ReactNode;
className?: string;
}
export function StatusBadge({ status, children, className }: StatusBadgeProps) {
return (
<Badge variant="secondary" className={statusVariants({ status, className })}>
{children}
</Badge>
);
}
```
### 4. Layout Wrapper
```typescript
interface PageLayoutProps {
children: React.ReactNode;
title: string;
description?: string;
actions?: React.ReactNode;
}
export function PageLayout({ children, title, description, actions }: PageLayoutProps) {
return (
<div className="flex-1 space-y-4 p-4 md:p-8 pt-6">
<div className="flex items-center justify-between">
<div>
<h2 className="text-3xl font-bold tracking-tight">{title}</h2>
{description && (
<p className="text-muted-foreground">{description}</p>
)}
</div>
{actions && <div className="flex items-center space-x-2">{actions}</div>}
</div>
{children}
</div>
);
}
```
These templates provide a solid foundation for building Backstage-style applications with consistent patterns, proper TypeScript types, and responsive design.

# Backstage Design System Implementation Guide
## Core Architecture Overview
The Backstage Design System is built on modern React patterns and industry-standard libraries:
### Technology Stack
- **React 18+** with TypeScript
- **Radix UI Primitives** for accessible, headless components
- **Tailwind CSS** for utility-first styling
- **Class Variance Authority (CVA)** for type-safe component variants
- **React Hook Form** with Zod validation
- **Lucide React** for consistent iconography
### Key Design Principles
1. **Accessibility First**: Built on Radix UI primitives with ARIA support
2. **Type Safety**: Full TypeScript coverage with strict typing
3. **Composability**: Components designed for flexible composition
4. **Consistency**: Unified design tokens and patterns
5. **Performance**: Optimized for bundle size and runtime performance
## Component Architecture Patterns
### 1. Compound Components
Components are designed with multiple sub-components for maximum flexibility:
```typescript
// Card component structure
<Card>
<CardHeader>
<CardTitle>Title</CardTitle>
<CardDescription>Description</CardDescription>
<CardAction>Action buttons</CardAction>
</CardHeader>
<CardContent>
Main content
</CardContent>
<CardFooter>
Footer content
</CardFooter>
</Card>
```
### 2. Variant-Based Styling
Using CVA for type-safe, predictable component variants:
```typescript
const buttonVariants = cva(
"inline-flex items-center justify-center rounded-md text-sm font-medium",
{
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-input bg-background hover:bg-accent",
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: "h-10 w-10",
},
},
defaultVariants: {
variant: "default",
size: "default",
},
}
);
```
### 3. Data Attributes for Styling
Consistent use of data attributes for component identification and styling:
```typescript
<div
data-slot="card"
className="bg-card text-card-foreground rounded-lg border"
>
<div data-slot="card-header">
{/* Header content */}
</div>
</div>
```
## Theme System Implementation
### 1. Color Architecture
#### Brand Colors (11-step scale)
```css
:root {
--brand-050: #F5F1F0; /* 最浅背景色 */
--brand-100: #E9DDDB; /* Hover background / light tint */
--brand-200: #D6BEBB; /* Soft background */
--brand-300: #B78F8A; /* Subtle brand tint */
--brand-400: #94635E; /* Hover / outline */
--brand-500: #6A4040; /* Primary brand color */
--brand-600: #5B3535; /* Active / pressed */
--brand-700: #4C2D2D; /* Stronger contrast */
--brand-800: #3E2525; /* Deep background */
--brand-900: #2E1C1C; /* Text on light */
--brand-950: #1C1010; /* Text on dark / darkest tone */
}
```
#### Semantic Color Tokens
```css
:root {
/* === Light Mode === */
--background: hsl(48, 33%, 98%);
--foreground: hsl(0, 25%, 33%);
--card: hsl(48, 33%, 98%);
--card-foreground: hsl(0, 25%, 33%);
--popover: hsl(48, 33%, 98%);
--popover-foreground: hsl(0, 25%, 33%);
--primary: hsl(222, 28%, 14%);
--primary-foreground: hsl(48, 33%, 98%);
--secondary: hsl(210, 25%, 96%);
--secondary-foreground: hsl(0, 25%, 33%);
--muted: hsl(210, 25%, 96%);
--muted-foreground: hsl(215, 9%, 46%);
--accent: hsl(210, 25%, 96%);
--accent-foreground: hsl(0, 25%, 33%);
--destructive: hsl(0, 82%, 67%);
--destructive-foreground: hsl(48, 33%, 98%);
--border: hsl(0, 14%, 94%);
--input: hsl(214, 27%, 91%);
--ring: hsl(0, 25%, 33%);
}
[data-theme='dark'] {
/* === Dark Mode === */
--background: hsl(0, 25%, 6%);
--foreground: hsl(48, 33%, 98%);
--card: hsl(0, 25%, 6%);
--card-foreground: hsl(48, 33%, 98%);
--popover: hsl(0, 25%, 6%);
--popover-foreground: hsl(48, 33%, 98%);
--primary: hsl(48, 33%, 98%);
--primary-foreground: hsl(0, 25%, 33%);
--secondary: hsl(0, 22%, 14%);
--secondary-foreground: hsl(48, 33%, 98%);
--muted: hsl(0, 22%, 14%);
--muted-foreground: hsl(0, 20%, 75%);
--accent: hsl(0, 22%, 14%);
--accent-foreground: hsl(48, 33%, 98%);
--destructive: hsl(0, 82%, 67%);
--destructive-foreground: hsl(48, 33%, 98%);
--border: hsl(0, 22%, 14%);
--input: hsl(0, 22%, 14%);
--ring: hsl(0, 25%, 33%);
}
```
### 2. Font Families
```css
/* Import custom fonts */
@font-face {

}
/* Headings */
h1, h2, h3, h4, h5, h6,

.heading-4 .preposition, .heading-5 .preposition, .heading-6 .preposition {
font-style: italic;
}
```
### 3. Typography Scale
```css
.text-xxs { font-size: 8px; } /* Micro text */
.text-xs { font-size: 10px; } /* Caption */
.text-sm { font-size: 12px; } /* Secondary text */
.text-base { font-size: 14px; } /* Default body */
.text-lg { font-size: 16px; } /* Paragraph */
.display-xl { font-size: 60px; } /* Hero headings */
```
### 4. Spacing System (4px base unit)
```css
.space-1 { margin: 4px; } /* XS */
.space-2 { margin: 8px; } /* SM */
.space-3 { margin: 12px; } /* MD */
.space-4 { margin: 16px; } /* LG - Component spacing */
.space-6 { margin: 24px; } /* Standard spacing */
.space-8 { margin: 32px; } /* Section padding */
.space-16 { margin: 64px; } /* Large sections */
```
## Responsive Design Strategy
### 1. Breakpoint System
```css
/* Mobile-first approach */
sm: '640px', /* Small devices */
md: '768px', /* Tablets */
lg: '1024px', /* Laptops */
xl: '1280px', /* Desktops */
2xl: '1536px' /* Large screens */
```
### 2. Component Responsiveness
```typescript
// Example: Responsive grid
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
{/* Cards automatically adapt */}
</div>
// Custom mobile hook
const isMobile = useIsMobile(); // 768px breakpoint
```
### 3. Sidebar Adaptation
```typescript
// Desktop: Collapsible sidebar
// Mobile: Transforms to sheet/drawer
{isMobile ? (
<Sheet open={openMobile} onOpenChange={setOpenMobile}>
<SheetContent side="left" className="p-0">
<SidebarContent />
</SheetContent>
</Sheet>
) : (
<Sidebar className={cn(
"transition-all duration-300",
state === "collapsed" ? "w-[48px]" : "w-[256px]"
)}>
<SidebarContent />
</Sidebar>
)}
```
## Accessibility Implementation
### 1. ARIA Patterns
```typescript
// Proper ARIA labeling
<button
aria-label="Close dialog"
aria-expanded={isOpen}
aria-controls="dialog-content"
>
<X className="h-4 w-4" />
</button>
// Form accessibility
<label htmlFor="email" className="sr-only">
Email address
</label>
<input
id="email"
type="email"
aria-describedby="email-description"
aria-invalid={hasError}
/>
<div id="email-description" className="text-sm text-muted-foreground">
We'll never share your email
</div>
```
### 2. Keyboard Navigation
```typescript
// Custom keyboard event handling
useEffect(() => {
const handleKeyDown = (event: KeyboardEvent) => {
if (event.key === 'Escape') {
onClose();
}
if (event.key === 'Enter' || event.key === ' ') {
onActivate();
}
};
document.addEventListener('keydown', handleKeyDown);
return () => document.removeEventListener('keydown', handleKeyDown);
}, [onClose, onActivate]);
```
### 3. Focus Management
```typescript
// Focus trap for modals
import { FocusTrap } from '@radix-ui/react-focus-trap';
<FocusTrap asChild>
<div className="modal-content">
{/* Modal content with proper focus order */}
</div>
</FocusTrap>
```
## Form Architecture
### 1. React Hook Form Integration
```typescript
import { useForm } from "react-hook-form";
import { zodResolver } from "@hookform/resolvers/zod";
import * as z from "zod";
const formSchema = z.object({
email: z.string().email("Invalid email address"),
password: z.string().min(8, "Password must be at least 8 characters"),
});
type FormData = z.infer<typeof formSchema>;
const form = useForm<FormData>({
resolver: zodResolver(formSchema),
defaultValues: {
email: "",
password: "",
},
});
```
### 2. Form Field Component Pattern
```typescript
<FormField
control={form.control}
name="email"
render={({ field }) => (
<FormItem>
<FormLabel>Email</FormLabel>
<FormControl>
<Input placeholder="Enter your email" {...field} />
</FormControl>
<FormDescription>
We'll use this to send you updates
</FormDescription>
<FormMessage />
</FormItem>
)}
/>
```
## State Management Patterns
### 1. Component State
```typescript
// Local state for UI interactions
const [isOpen, setIsOpen] = useState(false);
const [selectedItems, setSelectedItems] = useState<string[]>([]);
// Derived state
const hasSelection = selectedItems.length > 0;
const allSelected = selectedItems.length === items.length;
```
### 2. Context for Shared State
```typescript
// Theme context
const ThemeContext = createContext<{
theme: Theme;
setTheme: (theme: Theme) => void;
} | null>(null);
// Sidebar context
const SidebarContext = createContext<{
state: "expanded" | "collapsed";
open: boolean;
setOpen: (open: boolean) => void;
isMobile: boolean;
} | null>(null);
```
### 3. URL State Management
```typescript
// For filters, search, pagination
const [searchParams, setSearchParams] = useSearchParams();
const currentPage = Number(searchParams.get('page')) || 1;
const searchQuery = searchParams.get('q') || '';
const updateFilters = (filters: Record<string, string>) => {
const newParams = new URLSearchParams(searchParams);
Object.entries(filters).forEach(([key, value]) => {
if (value) {
newParams.set(key, value);
} else {
newParams.delete(key);
}
});
setSearchParams(newParams);
};
```
## Performance Optimization
### 1. Code Splitting
```typescript
// Lazy loading for routes
const Dashboard = lazy(() => import('./pages/Dashboard'));
const Settings = lazy(() => import('./pages/Settings'));
// Wrap in Suspense
<Suspense fallback={<LoadingSpinner />}>
<Routes>
<Route path="/dashboard" element={<Dashboard />} />
<Route path="/settings" element={<Settings />} />
</Routes>
</Suspense>
```
### 2. Memoization
```typescript
// Expensive calculations
const processedData = useMemo(() => {
return data.map(item => ({
...item,
computed: expensiveComputation(item)
}));
}, [data]);
// Callback memoization
const handleItemClick = useCallback((id: string) => {
setSelectedItems(prev =>
prev.includes(id)
? prev.filter(item => item !== id)
: [...prev, id]
);
}, []);
// Component memoization
const MemoizedTableRow = memo(TableRow);
```
### 3. Virtual Scrolling (for large lists)
```typescript
import { FixedSizeList as List } from 'react-window';
const VirtualizedTable = ({ items }: { items: any[] }) => {
const Row = ({ index, style }: { index: number; style: React.CSSProperties }) => (
<div style={style}>
<TableRow data={items[index]} />
</div>
);
return (
<List
height={600}
itemCount={items.length}
itemSize={50}
width="100%"
>
{Row}
</List>
);
};
```
## Testing Patterns
### 1. Component Testing
```typescript
import { render, screen, fireEvent } from '@testing-library/react';
import { Button } from './button';
describe('Button', () => {
it('renders with correct variant styles', () => {
render(<Button variant="destructive">Delete</Button>);
const button = screen.getByRole('button');
expect(button).toHaveClass('bg-destructive');
});
it('handles click events', () => {
const handleClick = jest.fn();
render(<Button onClick={handleClick}>Click me</Button>);
fireEvent.click(screen.getByRole('button'));
expect(handleClick).toHaveBeenCalledTimes(1);
});
});
```
### 2. Accessibility Testing
```typescript
import { axe, toHaveNoViolations } from 'jest-axe';
expect.extend(toHaveNoViolations);
it('should not have accessibility violations', async () => {
const { container } = render(<MyComponent />);
const results = await axe(container);
expect(results).toHaveNoViolations();
});
```

transition: transform var(--duration-normal) var(--ease-in-out);
}
.hover-lift:hover {
transform: translateY(-2px);
}
/* Scale on Hover */
.hover-scale {
transition: transform var(--duration-normal) var(--ease-in-out);
}
.hover-scale:hover {
transform: scale(1.05);
}
```
### Loading States
```css
@keyframes pulse {
0%, 100% { opacity: 1; }
50% { opacity: 0.5; }
}
.loading {
