Next.js Server Components

Introduction

Next.js 13 introduces Server Components, which allow rendering parts of your React app on the server. This improves performance, SEO, and reduces client-side bundle size.

Key Features

• Runs on the server
• Direct server-side data fetching
• Avoids unnecessary client-side JavaScript

// app/page.jsx
export default function Page() {
  const data = await fetchData();
  return <h1>{data.title}</h1>;
}

Best Practices

• Use Server Components for heavy data fetching
• Combine with Client Components for interactivity
• Pass minimal props from server to client
• Keep components focused and reusable

Fullstack Example

• Fetch user data from a database
• Render posts and comments server-side
• Interactive features handled with Client Components
