Google analytics ga.js is deprecated

[kakawait]

Actual behavior

https://github.com/LouisBarranqueiro/hexo-theme-tranquilpeak/blob/master/layout/_partial/google-analytics.ejs

is using ga.js that is now deprecated by google itself

ga.js is a legacy library. If you are starting a new implementation we recommend you use the latest version of this library, analytics.js. For exisiting implementations, learn how to migrate from ga.js to analytics.js.

Expected behavior

Migrate to analytics.js

Here two possibility

1. Common way (sync)

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', '<%= theme.google_analytics_id %>', 'auto');
  ga('send', 'pageview');

</script>

or using async from HTML5 to do not block website (http://caniuse.com/#feat=script-async)

<script>
window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date;
ga('create', '<%= theme.google_analytics_id %>', 'auto');
ga('send', 'pageview');
</script>
<script async src='//www.google-analytics.com/analytics.js'></script>

I would go for async way.

[kakawait]

On my fork I set async as default but configuration to allow switch if your user target is using old browser that do not support async

PS: You can check your user browser in google analytics, great news :)
