Next.js install
Next.js ships a <Script> component built to load external scripts without slowing the page down. That's the method we recommend.
App Router (Next 13+)
In app/layout.tsx:
import Script from 'next/script';
export default function RootLayout({ children }) {
return (
<html lang="en">
<body>
{children}
<Script
id="snorklee"
src="https://snorklee.com/w.js"
data-site="yoursite.com"
strategy="afterInteractive"
/>
</body>
</html>
);
}
Pages Router (Next 12 and earlier)
In pages/_document.tsx or pages/_app.tsx:
import Script from 'next/script';
// inside the root component, after other scripts
<Script
id="snorklee"
src="https://snorklee.com/w.js"
data-site="yoursite.com"
strategy="afterInteractive"
/>;
Notes
afterInteractivestrategy: the code loads once the page is interactive, without blocking the first paint.- Next.js asks for the
idattribute so the code isn't added twice. - For dynamic routes, you add the code just once (in the layout); page changes on the client side are counted automatically, with nothing to configure.
