Page Specification

$ARGUMENTS

Next.js 15 App Router Standards

1. File Structure

app/
   [route]/
      page.tsx          # Main page component
      layout.tsx        # Layout (optional)
      loading.tsx       # Loading UI
      error.tsx         # Error UI
      not-found.tsx     # 404 UI

2. Server Components by Default

• Fetch data directly in components
• No need for getServerSideProps/getStaticProps
• Async components supported
• Better performance

3. Metadata

export const metadata: Metadata = {
  title: 'Page Title',
  description: 'Page description for SEO',
  openGraph: { /* OG tags */ }
}

4. Data Fetching Patterns

Server Component (preferred)

async function Page() {
  const data = await fetchData()
  return <div>{data}</div>
}

Client Component (when needed)

'use client'
function Page() {
  const { data } = useSWR('/api/data')
  return <div>{data}</div>
}

What to Generate

1. Page Component - app/[route]/page.tsx
2. TypeScript Types - Props and data types
3. Loading State - loading.tsx
4. Error Boundary - error.tsx
5. Metadata - SEO and OG tags
6. Example Data Fetching - Server or client patterns

Page Patterns

Static Page (default)

• Pre-rendered at build time
• Best for marketing pages, blogs
• Fast performance

Dynamic Page (revalidation)

export const revalidate = 60 // Revalidate every 60 seconds

Dynamic Route ([slug])

export async function generateStaticParams() {
  // Generate paths at build time
}

Streaming (with Suspense)

<Suspense fallback={<Loading />}>
  <AsyncComponent />
</Suspense>

Best Practices

Structure

• Server Components for data fetching
• Client Components only when needed ('use client')
• Streaming with Suspense for slow data
• Parallel data fetching
• Proper TypeScript typing

Performance

• Image optimization (next/image)
• Font optimization (next/font)
• Lazy loading below the fold
• Code splitting automatically
• Prefetch links (default behavior)

SEO

• Metadata for every page
• Semantic HTML
• Open Graph tags
• Structured data (JSON-LD)
• Alt text for images

Error Handling

• error.tsx for runtime errors
• not-found.tsx for 404s
• Graceful degradation
• User-friendly error messages

Accessibility

• Semantic HTML5 elements
• ARIA labels
• Keyboard navigation
• Focus management

When to Use Client Components

Use 'use client' when you need:

• Event listeners (onClick, onChange, etc.)
• State hooks (useState, useReducer)
• Effect hooks (useEffect, useLayoutEffect)
• Browser-only APIs (localStorage, window)
• Custom hooks that use above

Otherwise, use Server Components (default).

Styling Integration

Choose based on project:

• Tailwind CSS - Utility classes (recommended)
• CSS Modules - Scoped styles
• Styled Components - CSS-in-JS (requires 'use client')

Generate a complete, production-ready Next.js page with proper TypeScript types, error handling, and SEO optimization.
