How can I implement analytics in my Next.js application?

You can use libraries like Google Analytics or Mixpanel. Would you like a step-by-step guide for one of them?

Yes, please provide a guide for Google Analytics.

First, create a Google Analytics account and get your tracking ID. Then, install the next/script package in your Next.js app.

What code do I need to add to my Next.js app?

You can add the following code in your _app.js file:

import { useEffect } from 'react';
import Script from 'next/script';

function MyApp({ Component, pageProps }) {
  useEffect(() => {
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
    gtag('config', 'YOUR_TRACKING_ID');
  }, []);

  return (
    <> 
      <Script async src="https://www.googletagmanager.com/gtag/js?id=YOUR_TRACKING_ID" />
      <Script id="google-analytics">
        {`window.dataLayer = window.dataLayer || [];
        function gtag(){dataLayer.push(arguments);}
        gtag('js', new Date());
        gtag('config', 'YOUR_TRACKING_ID');`}
      </Script>
      <Component {...pageProps} />
    </>
  );
}

export default MyApp;

What else can I track with Google Analytics?

You can track user interactions like page views, events, conversions, and user demographics.
