How can I embed tracking JS into Discourse

Community Building Data & reporting

AI-generated summary

jakubgs is trying to embed a Fathom Analytics tracking JS script into their Discourse site. They’ve added the script to the <head> section via the Customize > Theme > Custom CSS/HTML settings, but it’s failing to load the tracker.js script and throwing errors in the console. They’ve also added their Fathom domain to the allowed domains in the Content Security Policy. jrgong is considering using Fathom as an alternative to Google Analytics and inquires if jakubgs was able to resolve the issue.

I’m using Fathom Analytics and trying to embed some JS script for site tracking, which looks like this:

<!-- Fathom - simple website analytics - https://github.com/usefathom/fathom -->
<script>
(function(f, a, t, h, o, m){
	a[h]=a[h]||function(){
		(a[h].q=a[h].q||[]).push(arguments)
	};
	o=f.createElement('script'),
	m=f.getElementsByTagName('script')[0];
	o.async=1; o.src=t; o.id='fathom-script';
	m.parentNode.insertBefore(o,m)
})(document, window, '//fathom.example.org/tracker.js', 'fathom');
fathom('set', 'siteId', 'ABCDEF');
fathom('trackPageview');
</script>
<!-- / Fathom -->

I’m adding this to <head> section via the Customize > Theme > Custom CSS/HTML settings.
But when I load the side the fetching of the Fathom tracker.js script fails:

discource_fathom_err_1
discource_fathom_err_11283×189 33 KB

And the console show other failures:

Uncaught (in promise) no-response: no-response :: [{"url":"https://fathom.example.org/tracker.js"}]
    at a.makeRequest (https://discuss.example.org/javascripts/workbox/workbox-strategies.prod.js:1:2145)

It seems like Fathom is messing with the fetching of that JS. How am I supposed to do this?

I’m on 2.6.0.beta1.

Oh, and I should also add that I have seen this:

And have added my Fathom domain to allows ones in the Content Security Policy allowed domains.

Hey @jakubgs

digging out this oldie!

Have you been able to make it work? I am considering fathom to replace google analytics.
