nextjs - How to set up Google Analytics through Google Tag Manager for Next-Js? -

-



formerly using react-ga npm module insert google analytics in next js app. , this:

import reactga 'react-ga'  export const initga = () => {   reactga.initialize('ua-*******-*', {     titlecase: false   }) }  export const logpageview = () => {   if (window.location.href.split('?')[1]) {     reactga.set({page: window.location.pathname + '?' + window.location.href.split('?')[1]})     reactga.pageview(window.location.pathname + '?' + window.location.href.split('?')[1])   } else {     reactga.set({page: window.location.pathname})     reactga.pageview(window.location.pathname)   } }

and calling logpageview function in header(that inserted every page of app) this:

  componentdidmount () {     if (!window.ga_initialized) {       initga()       window.ga_initialized = true     }     logpageview()   }   componentwillreceiveprops () {     if (!window.ga_initialized) {       initga()       window.ga_initialized = true     }     logpageview()   }

now want use google tag manager handle analytics page view . how this?

in order use google tag manager should inject tag manager script on every page. since _document.js wrapper every page. should insert tag manager's script in _document.js in head section this:

<head>         <script dangerouslysetinnerhtml={{           __html: `(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':           new date().gettime(),event:'gtm.js'});var f=d.getelementsbytagname(s)[0],           j=d.createelement(s),dl=l!='datalayer'?'&l='+l:'';j.async=true;j.src=           'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentnode.insertbefore(j,f);         })(window,document,'script','datalayer','gtm-*****');`,         }}>         </script> ... </head>

now set use google tag manager in next-js app should proceed handle pageview , other analytics related stuff tag manager dashboard.

to set google analytics pageview single page applications(like nextjs) can follow these steps.
