Understanding Next.js Server Components

## What are Server Components?

React Server Components (RSCs) are a new paradigm in React development that allows components to render on the server, reducing the JavaScript sent to the client.

Benefits

1. 1.**Reduced Bundle Size**: Server Components don't add to your JavaScript bundle
2. 2.**Direct Backend Access**: You can query databases directly in your components
3. 3.**Automatic Code Splitting**: Only client components are sent to the browser

Example

// This component runs only on the server
async function BlogPosts() {

return ( <ul> {posts.map(post => ( <li key={post.id}>{post.title}</li> ))} </ul> ); } ```

When to Use Client Components

• ▹Event handlers (onClick, onChange, etc.)
• ▹State (useState, useReducer)
• ▹Lifecycle effects (useEffect)
• ▹Browser-only APIs

Conclusion

Server Components represent a fundamental shift in how we build React applications. They offer significant performance benefits while maintaining the component model we love.
