NextJS TopLoader Next Js TopLoader
- A Next.js Top Loading Bar component made using nprogress, works with Next.js 14 and React.
using npm:
npm install nextjs-toploader
using yarn:
yarn add nextjs-toploader
import using:
import NextTopLoader from 'nextjs-toploader';
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> ); }
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
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');
For triggering TopLoader when using useRouter add <PagesTopLoader /> to your return() in MyApp() :
import { PagesTopLoader } from 'nextjs-toploader/pages'; export default function MyApp({ Component, pageProps }) { return ( <> <PagesTopLoader /> <Component {...pageProps} />; </> ); }
A custom hook for handling progress indicators using NextTopLoader.
