Server Components (RSC) - Flowbite React

React Server Components are a powerful feature that allows components to be rendered entirely on the server. When used with Flowbite React, they offer several benefits:

• 🚀 Reduced client-side JavaScript bundle size
• ⚡ Improved initial page load performance
• 🔄 Server-side data fetching

Server vs Client Components#

Server Components (Default)#

By default, all components in React are now server components. They don't need any special directive:

import { Button } from "flowbite-react";

function ServerComponent() {
  // ✅ Works: Static button without interactions
  return <Button>Click Me</Button>;
}

Client Components#

To handle user interactions (like clicks or input), you need to mark your component as a client component using the "use client" directive:

"use client";

import { Button } from "flowbite-react";

function ClientComponent() {
  // ✅ Works: Button with click handler
  return <Button onClick={() => console.log("clicked!")}>Interactive Button</Button>;
}

Common Pitfalls#

❌ Wrong: Event Handlers in Server Components#

// This will cause an error!
import { Button } from "flowbite-react";

function ServerComponent() {
  return <Button onClick={() => console.log("clicked!")}>This Won't Work</Button>;
}

✅ Correct: Event Handlers in Client Components#

"use client";

import { Button } from "flowbite-react";

function ClientComponent() {
  return <Button onClick={() => console.log("clicked!")}>This Works Fine</Button>;
}

Important Notes#

1. Flowbite React Compatibility

   • All Flowbite React components are server-component ready
   • They can be used in both server and client components

2. Event Handlers

   • User events (onClick, onBlur, etc.) require "use client"
   • The component containing these events must be a client component

3. Props Limitations

   • Only serializable data can be passed to server components
   • Functions, complex objects, and React nodes might not work as props in server components

Best Practices#

• Use server components by default for static content
• Switch to client components only when you need:
  • User interactions (event handlers)
  • Browser APIs
  • State management
  • Effects

This approach ensures optimal performance while maintaining full functionality.

Support#

💡 Full Server Component Support

Flowbite React is fully optimized for React Server Components:

• All components work out-of-the-box in server components
• Zero configuration needed for server-side rendering
• Automatic client/server boundary handling
• Optimized for performance in both environments

Just remember to add "use client" only when you need interactivity:

"use client";

import { Button, Modal } from "flowbite-react";

function InteractiveWidget() {
  // ✅ Use client components when you need interactivity
  return <Button onClick={() => setIsOpen(true)}>Open Modal</Button>;
}
