# Next.js App Router Architecture Best Practices

Next.js App Router provides maximum performance when leveraging React Server Components by default.

## 1. Keep Client Boundaries Small

Isolate interactivity to leaf nodes:

```tsx
// Server Component (Default)
import { UserProfile } from './user-profile';
import { InteractiveLikeButton } from './like-button';

export default async function Page() {
  const user = await fetchUserData();
  return (
    <div>
      <UserProfile user={user} />
      <InteractiveLikeButton initialLikes={user.likes} />
    </div>
  );
}
```
