Minimal Google Analytics Snippet

A simple snippet for tracking page views on your website without having to add external libraries. Also works for single page applications made with the likes of react and vue.js.

Before

Google Tag Manager + Analytics = 73kB

After

Snippet = 1.5kB

How does this work?

This snippet sends page views directly to the Google Analytics API. There is no need to add the Google Tag Manager and Analytics libraries anymore. That not only saves bandwidth, it can also have a huge positive impact on the loading speed of your website. You should not use this if you want to use advanced features like tracking AdWords.

<script>
  (function(a,b,c){var d=a.history,e=document,f=navigator||{},g=localStorage,
  h=encodeURIComponent,i=d.pushState,k=function(){return Math.random().toString(36)},
  l=function(){return g.cid||(g.cid=k()),g.cid},m=function(r){var s=[];for(var t in r)
  r.hasOwnProperty(t)&&void 0!==r[t]&&s.push(h(t)+"="+h(r[t]));return s.join("&")},
  n=function(r,s,t,u,v,w,x){var z="https://www.google-analytics.com/collect",
  A=m({v:"1",ds:"web",aip:c.anonymizeIp?1:void 0,tid:b,cid:l(),t:r||"pageview",

  (f.language||"").toLowerCase():void 0,de:c.characterSet?e.characterSet:void 0,

  a.visualViewport?(a.visualViewport||{}).width+"x"+(a.visualViewport||{}).height:void 0,
  ec:s||void 0,ea:t||void 0,el:u||void 0,ev:v||void 0,exd:w||void 0,exf:"undefined"!=typeof x&&
  !1==!!x?0:void 0});if(f.sendBeacon)f.sendBeacon(z,A);else{var y=new XMLHttpRequest;
  y.open("POST",z,!0),y.send(A)}};d.pushState=function(r){return"function"==typeof d.onpushstate&&
  d.onpushstate({state:r}),setTimeout(n,c.delay||10),i.apply(d,arguments)},n(),
  a.ma={trackEvent:function o(r,s,t,u){return n("event",r,s,t,u)},
  trackException:function q(r,s){return n("exception",null,null,null,null,r,s)}}})
  (window,"XX-XXXXXXXXX-X",{anonymizeIp:true,colorDepth:true,characterSet:true,screenSize:true,language:true});
</script>

Setup: Just put the snippet into your html, replace 'XX-XXXXXXXXX-X' with your tracking id and you're ready to go. You can also add options for what information you want to track.

Event: ma.trackEvent('Category', 'Action', 'Label', 'Value')

Exception: ma.trackException('Description', 'Fatal')
