# Next.js & Edge-first Web: React Server Components, Edge Functions, and Performance

Modern web apps require speed and SEO. With **Next.js 14**, **React Server Components (RSC)** and **Edge Functions**, you can deliver highly optimized, SEO-friendly experiences with minimal TTFB (Time to First Byte).

## What’s new & why it matters
- **Edge-first rendering** reduces TTFB and improves perceived performance for global audiences.  
- **React Server Components** let you fetch data server-side while keeping client bundles small.  
- **Turbopack** and improved build pipelines speed up local dev and CI builds.

## SEO best practices with Next.js
- Use **generateMetadata** in App Router to render meta tags server-side.  
- Use server-side rendered content for critical SEO pages (blog posts, product pages).  
- Pre-render structured data (JSON-LD) for rich snippets.

## Architecture patterns
1. **Edge-rendered landing pages**: serve marketing pages from the edge with incremental revalidation.  
2. **Hybrid product pages**: RSC for product data, client components for interactive widgets.  
3. **Edge middleware**: A/B tests, geo-redirects, and personalization at the edge.

## Implementation tips
- Cache at CDN and use **stale-while-revalidate** for frequently updated content.  
- Keep server components free of client-only hooks.  
- Use **next/image** and modern image formats (AVIF/WebP) for performance and SEO signals.

## Example: server component fetching data at edge
```tsx
// app/products/[slug]/page.tsx
export async function generateMetadata({ params }) {
  const product = await fetchProduct(params.slug);
  return { title: product.title, description: product.description };
}

export default async function ProductPage({ params }) {
  const product = await fetchProduct(params.slug);
  return (
    <article>
      <h1>{product.title}</h1>
      <p>{product.description}</p>
    </article>
  );
}
