# Add Privatus Analytics to Next.js

> Add cookieless analytics to Next.js with next/script, for the App or Pages Router, with custom events from client components.

## Add the script

App Router: use `next/script` in the root layout, `app/layout.tsx`:

```tsx
import Script from 'next/script'

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <body>
        {children}
        <Script defer src="https://privatusstats.com/js/pa.js" data-site="pa_YOURSITEID" data-modules="engage,auto,vitals,clicks,ask" strategy="afterInteractive" />
      </body>
    </html>
  )
}
```

Pages Router: render the same `<Script>` in `pages/_app.tsx`.

Next.js client navigations use `history.pushState`, which the tracker
follows with its default `data-spa="auto"`. Every tracker option is a
`data-` attribute on the script (see [attributes](/docs/tracker/attributes)).

## Track events

```tsx
'use client'

export function UpgradeButton() {
  return (
    <button onClick={() => window.privatus?.track('Upgrade', { plan: 'pro' })}>
      Upgrade
    </button>
  )
}
```

For types on `window.privatus`, add the declarations from the
[JavaScript API](/docs/tracker/javascript-api#typescript) page.
