// pages/_app.tsx

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

const App = ({ Component, pageProps }) => {
  const router = useRouter()

  useEffect(() => {
    import('react-facebook-pixel')

        ReactPixel.pageView()

        router.events.on('routeChangeComplete', () => {
          ReactPixel.pageView()
        })
      })
  }, [router.events])

  

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

export default App
