In Next.js, we can achieve this using the usePathname() hook. This hook checks the current path in the app, allowing us to implement dynamic highlighting for the corresponding page with the clsx library.

Back to the Project

To utilize usePathname() hook, convert nav-links.tsx into a Client Component. Begin by adding "use client" directive at the top of the file.

app/ui/dashboard/nav-links.tsx

'use client';

import {
  HomeModernIcon,
  ClipboardDocumentListIcon,
} from '@heroicons/react/24/outline';
// ...

Now, we can use the usePathname hook and use it.

app/ui/dashboard/nav-links.tsx

// ...
import Link from 'next/link';
import { usePathname } from 'next/navigation';

const links = [
  // ...
];

export default function NavLinks() {
  const pathname = usePathname();

  return (
    {/* ... */}
  );
}

Lastly, employ the clsx library to apply styles conditionally. Set the condition such that if the pathname is equal to link.href, change the background color to bg-neutral-600.

app/ui/dashboard/nav-links.tsx

// ...
import Link from 'next/link';
import { usePathname } from 'next/navigation';
import clsx from 'clsx';

const links = [
  // ...
];

export default function NavLinks() {
  const pathname = usePathname();

  return (
    <>
      {links.map((link) => {
        const LinkIcon = link.icon;
        return (
          <Link
            key={link.name}
            href={link.href}
            className={clsx(
              'text-wh flex h-[48px] grow items-center justify-center gap-2 rounded-md bg-neutral-900 p-3 text-sm font-medium text-white hover:bg-neutral-600 hover:text-white md:flex-none md:justify-start md:p-2 md:px-3',
              {
                'bg-neutral-600': pathname === link.href,
              },
            )}
          >
            <LinkIcon className="w-6" />
            <p className="hidden md:block">{link.name}</p>
          </Link>
        );
      })}
    </>
  );
}

Creating Active Links

In web development, a common practice is highlighting active links based on the current page.

To utilize usePathname() hook, convert nav-links.tsx into a Client Component. Begin by adding "use client" directive at the top of the file.

app/ui/dashboard/nav-links.tsx

  return (

      {links.map((link) => {
        const LinkIcon = link.icon;
        return (
          <Link
            key={link.name}
            href={link.href}
            className={clsx(

          >
            <LinkIcon className="w-6" />
            <p className="hidden md:block">{link.name}</p>
          </Link>
