Installing Google Analytics in Blacklight

Create an environment variable on the server called GA_TRACKING_CODE.
Go to analytics.google.com’s admin dashboard and select click on ‘Tracking Info’
Copy the the global site tag. It will look like this:

         <!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-143063836-3"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-5555555-5');
</script>

Add this markup to the app/view/layouts/blacklight/base.html.erb as the first tag in the <head> tag, but replace the tracking code with the env variable: <%= ENV['GA_TRACKING_CODE'] %>

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=<%= ENV['GA_TRACKING_CODE']  %>"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', '<%= ENV['GA_TRACKING_CODE']  %>');
</script>

Add the ID to the server and in the -cm repositories for the project.
After deploying the code go to the Tracking Code page in GA and click “Send test traffic” to test that the code is active.
