NextJS Problem and Solutions

Problem: Unhandled Runtime Error in Next.js: "Event handlers cannot be passed to Client Component props."

Cause:

• In Next.js with the App Router, Server Components cannot handle interactivity like event handlers (onClick).
• The error occurs when trying to directly pass an event handler in a Server Component.

Solution:

1. Convert to a Client Component
   • Add "use client" at the top of the file.
2. Define Scroll Function & Attach to Button
   • Create a function to scroll to the "Contact" section.
   • Use scrollIntoView({ behavior: "smooth" }) to enable smooth scrolling.

Fixed Code:

"use client"; // Ensures it's a Client Component
import Head from "next/head";
 
export default function Home() {
  return (
    <>
    </>
  );
}

Key Takeaways:

• Always use "use client" when handling interactivity in Next.js App Router.
• Use document.getElementById("contact").scrollIntoView({ behavior: "smooth" }) for smooth scrolling.
• Ensure event handlers are defined inside Client Components.
