Next.js 谷歌分析与 ReactGA

Question

Hi there i'm using ReactGA4 for track my Analytics in Next app. I am facing the issue that i cant see the path where the user is until they reload the page. This is my code.

ReactGA.initialize("UA-xxxxxxx");
ReactGA.send("pageview");

Subscribe to the Router events and use the GA pageview interface.

Remember to use the routeChangeComplete which will send the pageview via the ReactGA method

Modified nextjs example

import { useEffect } from 'react'
import { useRouter } from 'next/router'

export default function MyApp({ Component, pageProps }) {
  const router = useRouter()

  useEffect(() => {
    const handleRouteChange = (url, { shallow }) => {

   // REACTGA 
// Send pageview with a custom path
ReactGA.send({ hitType: "pageview", page: "/my-path" });


      console.log(
        `App is changing to ${url} ${
          shallow ? 'with' : 'without'
        } shallow routing`
      )
    }

    router.events.on('routeChangeComplete', handleRouteChange)

    // If the component is unmounted, unsubscribe
    // from the event with the `off` method:
    return () => {
      router.events.off('routeChangeComplete', handleRouteChange)
    }
  }, [])

  return <Component {...pageProps} />
}
