A Next.js Top Loading Bar component made using nprogress, works with Next.js 14 and React.

Install

npm install nextjs-toploader

using yarn:

yarn add nextjs-toploader

Usage

import using:

import NextTopLoader from 'nextjs-toploader';

Usage with `app/layout.js` for `app` folder structure

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

import NextTopLoader from 'nextjs-toploader';

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>
        <NextTopLoader />
        {children}
      </body>
    </html>
  );
}

Usage with `pages/_app.js` for `pages` folder structure

For rendering add <PagesTopLoader /> to your return() in MyApp() (Recommended):

import { PagesTopLoader } from 'nextjs-toploader/pages';

export default function MyApp({ Component, pageProps }) {
  return (
    <>
      <PagesTopLoader />
      <Component {...pageProps} />;
    </>
  );
}

You can also use <NextTopLoader /> in pages router, but it's recommended to use <PagesTopLoader /> for useRouter hook support from nextjs-toploader version 2.6.12 onwards

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');
