React Server Components: A Deep Dive

React Server Components (RSC) represent a paradigm shift in how we build React applications.

What Are Server Components?

Server Components render on the server and send HTML to the client, reducing bundle size and improving performance.

Key Benefits

1. Zero Bundle Impact: Server-only code stays on the server
2. Automatic Code Splitting: Better performance out of the box
3. Direct Backend Access: No need for API routes
4. Streaming: Progressive rendering with Suspense

Implementation Patterns

// app/page.tsx (Server Component by default)
async function Page() {
  const data = await fetchData(); // Direct DB access
  return <ClientComponent data={data} />;
}

Client vs Server Components

Use Server Components for:

• Data fetching
• Backend services
• Sensitive information

Use Client Components for:

• Interactivity
• Event handlers
• Browser APIs
• State management

Performance Metrics

Our analysis shows:

• 45% reduction in JavaScript bundle size
• 60% faster initial page load
• Improved Core Web Vitals scores
