For rendering add <NextTopLoader /> to your return() inside the <body></body> of RootLayout():

import NextTopLoader from 'nextjs-toploader';

export default function RootLayout({ children }) {
  return (

      <PagesTopLoader />
      <Component {...pageProps} />;

Compatibility with `useRouter` hook

For triggering TopLoader when using useRouter hook (app router):

// Import the useRouter hook from nextjs-toploader to trigger the TopLoader

import { useRouter } from 'nextjs-toploader/app';

Then simply use it in your code for example:

const router = useRouter();
router.push('/some-page');
