Understanding React Server Components

React Server Components (RSC) are a new feature that changes how we think about building React applications. Let's explore what they are and why they matter.

What are Server Components?

Server Components are components that render on the server, reducing the amount of JavaScript sent to the client. They can directly access backend resources.

Benefits

• Zero Bundle Size: Server Components don't add to your JavaScript bundle
• Direct Backend Access: Query databases directly in components
• Automatic Code Splitting: Load only what's needed
• Improved Performance: Less JavaScript means faster page loads

Example

// Server Component (runs on server)
async function UserProfile({ userId }: { userId: string }) {
  const user = await db.user.findUnique({ where: { id: userId } })

  return (
    <div>
      <h1>{user.name}</h1>
      <p>{user.email}</p>
    </div>
  )
}

Client vs Server Components

Understanding when to use each type is crucial:

• Use Server Components for data fetching, static content, and sensitive operations
• Use Client Components for interactivity, browser APIs, and state management
