Next.js

Fathom Analytics works well with Next.js with minimal configuration. A huge thank you to Derrick Reimer, founder of SavvyCal for creating the incredible fathom-client package.

If you're using Next.js App Router (v13.4+)

The App Router is the recommended approach for new Next.js applications. Here's how to set up Fathom:

Install the fathom-client package:

npm install fathom-client

Create a Fathom component to load the tracking script. Create a new file at app/components/Fathom.tsx:

'use client';
 
import { load, trackPageview } from 'fathom-client';
import { useEffect, Suspense } from 'react';
import { usePathname, useSearchParams } from 'next/navigation';
 
function TrackPageView() {
  const pathname = usePathname();
  const searchParams = useSearchParams();
 
  useEffect(() => {
    load('YOUR-SITE-ID', {
      auto: false
    });
  }, []);
 
  useEffect(() => {
    if (!pathname) return;
 
    trackPageview({
      url: pathname + searchParams?.toString(),
      referrer: document.referrer
    });
  }, [pathname, searchParams]);
 
  return null;
}
 
export default function Fathom() {
  return (
    <Suspense fallback={null}>
      <TrackPageView />
    </Suspense>
  );
}

Import and use the Fathom component in your root layout (app/layout.tsx):

import Fathom from './components/Fathom';
 
export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <body>
        <Fathom />
        {children}
      </body>
    </html>
  );
}

For more details, see the fathom-client App Router documentation.

If you're using Next.js Pages Router

If you're using the Pages Router (Next.js 12 or the pages/ directory in newer versions):

Please see the fathom-client Pages Router documentation.

Tracking events

To track custom events, you can use the trackEvent function from fathom-client:

import { trackEvent } from 'fathom-client';
 
// Track a simple event
trackEvent('Button Clicked');
 
// Track an event with a value (in cents for monetary values)
trackEvent('Purchase Completed', { _value: 9900 });
