Best Practices for Optimizing Nextjs Performance

Why Web Performance Matters

In modern web development, performance is not just a secondary feature—it's a critical component of user experience. Below are some best practices for Next.js applications:

1. Optimize Images: Always use the next/image component to automatically serve optimized formats (like WebP/AVIF) and prevent CLS.
2. Leverage the App Router: The new React Server Components architecture drastically reduces client-side JavaScript by streaming component renders securely.
3. Data Fetching: Utilize Next.js caching behavior effectively. Cache aggressively for static content and use revalidate wisely.

// Example Server Component Fetch
export default async function Page() {
  const data = await fetch('https://api.vercel.app/blog', { next: { revalidate: 3600 } })
  return <main>...</main>
}
