Understanding React Server Components

Introduction

React Server Components (RSC) represent a major shift in how we think about building React applications. By allowing components to render exclusively on the server, we can reduce bundle sizes and improve initial load performance.

Key Benefits

One of the primary advantages is zero-bundle-size components. Libraries used only on the server are not included in the client bundle.

"Server Components allow us to move data fetching logic to the server, closer to the data source."

Code Example

// Server Component
import db from './db';

async function Note({ id }) {
  const note = await db.notes.get(id);
  return (
    <div>
      <h2>{note.title}</h2>
      <p>{note.body}</p>
    </div>
  );
}

Conclusion

RSC is a game changer for performance and developer experience.
