## Project Scaffolding

Generate a new Next.js or React project with TypeScript, Tailwind CSS, and best practice configurations.

### Workflow: Create New Frontend Project

1. Run the scaffolder with your project name and template:
   ```bash
   python scripts/frontend_scaffolder.py my-app --template nextjs
   ```

2. Add optional features (auth, api, forms, testing, storybook):
   ```bash
   python scripts/frontend_scaffolder.py dashboard --template nextjs --features auth,api
   ```

3. Navigate to the project and install dependencies:
   ```bash
   cd my-app && npm install
   ```

4. Start the development server:
   ```bash
   npm run dev
   ```

### Scaffolder Options

| Option | Description |
|--------|-------------|
| `--template nextjs` | Next.js 14+ with App Router and Server Components |
| `--template react` | React + Vite with TypeScript |
| `--features auth` | Add NextAuth.js authentication |
| `--features api` | Add React Query + API client |
| `--features forms` | Add React Hook Form + Zod validation |
| `--features testing` | Add Vitest + Testing Library |
| `--dry-run` | Preview files without creating them |

### Generated Structure (Next.js)

## Component Generation

Generate React components with TypeScript, tests, and Storybook stories.

### Workflow: Create a New Component

1. Generate a client component:
   ```bash
   python scripts/component_generator.py Button --dir src/components/ui
   ```

2. Generate a server component:
   ```bash
   python scripts/component_generator.py ProductCard --type server
   ```

3. Generate with test and story files:
   ```bash
   python scripts/component_generator.py UserProfile --with-test --with-story
   ```

4. Generate a custom hook

## Accessibility (a11y)

### Semantic HTML

```tsx
// BAD - Divs for everything
<div onClick={handleClick}>Click me</div>
<div class="header">...</div>
<div class="nav">...</div>

// GOOD - Semantic elements
<button onClick={handleClick}>Click me</button>
<header>...</header>
<nav>...</nav>
<main>...</main>
<article>...</article>
<aside>...</aside>
<footer>...</footer>
```

### Keyboard Navigation

```tsx
// Ensure all interactive elements are keyboard accessible
function Modal({ isOpen, onClose, children }: ModalProps) {
  const modalRef = useRef<HTMLDivElement>(null);

  useEffect(() => {
    if (isOpen) {
      // Focus first focusable element
      const focusable = modalRef.current?.querySelectorAll(
        'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
      );
      (focusable?.[0] as HTMLElement)?.focus();

      // Trap focus within modal
      const handleTab = (e: KeyboardEvent) => {
        if (e.key === 'Tab' && focusable) {
          const first = focusable[0] as HTMLElement;
          const last = focusable[focusable.length - 1] as HTMLElement;

          if (e.shiftKey && document.activeElement === first) {
            e.preventDefault();
            last.focus();
          } else if (!e.shiftKey && document.activeElement === last) {
            e.preventDefault();
            first.focus();
          }
        }

        if (e.key === 'Escape') {
          onClose();
        }
      };

      document.addEventListener('keydown', handleTab);
      return () => document.removeEventListener('keydown', handleTab);
    }
  }, [isOpen, onClose]);

  if (!isOpen) return null;

  return (
    <div
      ref={modalRef}
      role="dialog"
      aria-modal="true"
      aria-labelledby="modal-title"
    >
      {children}
    </div>
  );
}
```

### ARIA Attributes

```tsx
// Live regions for dynamic content
<div aria-live="polite" aria-atomic="true">
  {status && <p>{status}</p>}
</div>

// Loading states
<button disabled={isLoading} aria-busy={isLoading}>
  {isLoading ? 'Loading...' : 'Submit'}
</button>

// Form labels
<label htmlFor="email">Email address</label>
<input
  id="email"
  type="email"
  aria-required="true"
  aria-invalid={!!errors.email}
  aria-describedby={errors.email ? 'email-error' : undefined}
/>
{errors.email && (
  <p id="email-error" role="alert">
    {errors.email}
  </p>
)}

// Navigation
<nav aria-label="Main navigation">
  <ul>
    <li><a href="/" aria-current={isHome ? 'page' : undefined}>Home</a></li>
    <li><a href="/about" aria-current={isAbout ? 'page' : undefined}>About</a></li>
  </ul>
</nav>

## Rendering Strategies

### Server Components (Default)

Server Components render on the server and send HTML to the client. Use for data-heavy, non-interactive content.

```tsx
// app/products/page.tsx - Server Component (default)
async function ProductsPage() {
  // This runs on the server - no client bundle impact
  const products = await db.products.findMany();

  return (
    <div className="grid grid-cols-3 gap-4">
      {products.map(product => (
        <ProductCard key={product.id} product={product} />
      ))}
    </div>
  );
}
```

### Client Components

Use `'use client'` only when you need:
- Event handlers (onClick, onChange)
- State (useState, useReducer)
- Effects (useEffect)
- Browser APIs (window, document)

```tsx
'use client';

import { useState } from 'react';

function AddToCartButton({ productId }: { productId: string }) {
  const [isAdding, setIsAdding] = useState(false);

  async function handleClick() {
    setIsAdding(true);
    await addToCart(productId);
    setIsAdding(false);
  }

  return (
    <button onClick={handleClick} disabled={isAdding}>
      {isAdding ? 'Adding...' : 'Add to Cart'}
    </button>
  );
}
```

### Mixing Server and Client Components

```tsx
// app/products/[id]/page.tsx - Server Component
async function ProductPage({ params }: { params: { id: string } }) {
  const product = await getProduct(params.id);

  return (
    <div>
      {/* Server-rendered content */}
      <h1>{product.name}</h1>
      <p>{product.description}</p>

      {/* Client component for interactivity */}
      <AddToCartButton productId={product.id} />

      {/* Server component for reviews */}
      <ProductReviews productId={product.id} />
    </div>
  );
}
```

### Static vs Dynamic Rendering

```tsx
// Force static generation at build time
export const dynamic = 'force-static';

// Force dynamic rendering at request time
export const dynamic = 'force-dynamic';

// Revalidate every 60 seconds (ISR)
export const revalidate = 60;

// Revalidate on-demand
import { revalidatePath, revalidateTag } from 'next/cache';

async function updateProduct(id: string, data: ProductData) {
  await db.products.update({ where: { id }, data });

  // Revalidate specific path
  revalidatePath(`/products/${id}`);

  // Or revalidate by tag
  revalidateTag('products');
}
```

---

## Image Optimization

### Next.js Image Component

```tsx
import Image from 'next/image';

// Basic optimized image
<Image
  src="/hero.jpg"
  alt="Hero image"
  width={1200}
  height={600}
  priority // Load immediately for LCP
/>

// Responsive ima

## Component Composition

### Compound Components

Use compound components when building reusable UI components with multiple related parts.

```tsx
// Compound component pattern for a Select
interface SelectContextType {
  value: string;
  onChange: (value: string) => void;
}

const SelectContext = createContext<SelectContextType | null>(null);

function Select({ children, value, onChange }: {
  children: React.ReactNode;
  value: string;
  onChange: (value: string) => void;
}) {
  return (
    <SelectContext.Provider value={{ value, onChange }}>
      <div className="relative">{children}</div>
    </SelectContext.Provider>
  );
}

function SelectTrigger({ children }: { children: React.ReactNode }) {
  const context = useContext(SelectContext);
  if (!context) throw new Error('SelectTrigger must be used within Select');

  return (
    <button className="flex items-center gap-2 px-4 py-2 border rounded">
      {children}
    </button>
  );
}

function SelectOption({ value, children }: { value: string; children: React.ReactNode }) {
  const context = useContext(SelectContext);
  if (!context) throw new Error('SelectOption must be used within Select');

  return (
    <div
      onClick={() => context.onChange(value)}
      className={`px-4 py-2 cursor-pointer hover:bg-gray-100 ${
        context.value === value ? 'bg-blue-50' : ''
      }`}
    >
      {children}
    </div>
  );
}

// Attach sub-components
Select.Trigger = SelectTrigger;
Select.Option = SelectOption;

// Usage
<Select value={selected} onChange={setSelected}>
  <Select.Trigger>Choose option</Select.Trigger>
  <Select.Option value="a">Option A</Select.Option>
  <Select.Option value="b">Option B</Select.Option>
</Select>
```

### Render Props

Use render props when you need to share behavior with flexible rendering.

```tsx
interface MousePosition {
  x: number;
  y: number;
}

function MouseTracker({ render }: { render: (pos: MousePosition) => React.ReactNode }) {
  const [position, setPosition] = useState<MousePosition>({ x: 0, y: 0 });

  useEffect(() => {
    const handleMouseMove = (e: MouseEvent) => {
      setPosition({ x: e.clientX, y: e.clientY });
    };
    window.addEventListener('mousemove', handleMouseMove);
    return () => window.removeEventListener('mousemove', handleMouseMove);
  }, []);

  return <>{render(position)}</>;
}

// Usage
<MouseTracker
  render={({ x, y }) => (
    <div>Mouse position: {x}, {y}</div>
  )}
/>
```

### Higher-Order Components (HOC)

Use HOCs for cross-cutting concerns like authentication or logging.

```tsx
function withAuth<P extends object>(WrappedComponent: React
