• Rendering Location: Client components can render on both the server and the client, while server components render exclusively on the server.
• Nesting Components: Server components can be passed as props to client components.

Server Components Explained

React Server Components (RSCs) are revolutionizing how we build web applications. They execute exclusively on the server, offering significant benefits.

What are Server Components?

Server Components are a new type of React component that renders on the server. They enable you to fetch data and render UI without sending JavaScript to the client, resulting in:

• Reduced bundle sizes
• Improved startup time
• Enhanced SEO

Key Benefits of Server Components

• Zero Client-Side JavaScript: Server Components' code isn't downloaded to the client, minimizing bundle size.
• Direct Database Access: Server Components can directly access backend resources, simplifying data fetching.
• Improved Performance: Rendering on the server can lead to faster initial page loads.

Server vs. Client Components

It's crucial to understand the distinction between Server and Client Components:

• Server Components: Render on the server, can't use client-side features (e.g., useState, useEffect).
• Client Components: Render on the client (and optionally the server for pre-rendering), can use the full range of React features.

When to Use Server Components

Server Components are ideal for:

• Data fetching
• Rendering non-interactive UI
• Accessing server-side resources

Declaring Client Components

In Next.js, Server Components are the default. To mark a component as a Client Component, use the "use client" directive at the top of the file:

   
    // MyComponent.jsx
    "use client"

    import { useState } from 'react';

    function MyComponent() {
     const [count, setCount] = useState(0);

     return (
      <div>
       <p>Count: {count}</p>
       <button onClick={() => setCount(count + 1)}>Increment</button>
      </div>
     );
    }

    export default MyComponent;
   
  

Nesting Components

You can't directly nest Server Components inside Client Components. However, you can pass Server Components as props to Client Components, allowing you to combine the benefits of both.

Client Components Explained

Client Components are a fundamental part of Next.js, enabling interactive user interfaces directly in the browser. Unlike Server Components that run on the server, Client Components allow you to use React features like:

• State Management
• Event Handlers
• Browser APIs

To designate a component as a Client Component, you add the "use client" directive at the top of the file. This tells Next.js to bundle and execute this component in the user's browser.

Here's a basic example:

   
// MyComponent.jsx
"use client"

import { useState } from 'react';

function MyComponent() {
 const [count, setCount] = useState(0);

 return (
  <div>
   <p>Count: {count}</p>
   <button onClick={() => setCount(count + 1)}>Increment</button>
  </div>
 );
}

export default MyComponent;
   
  

It's important to note that while Client Components offer interactivity, they also increase the JavaScript bundle size. Therefore, it's best practice to use them judiciously and only where necessary, placing them as low as possible in the component tree.
