using npm:
npm install nextjs-toploaderusing yarn:
yarn add nextjs-toploaderimport 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.
