Change data before it's sent to GoatCounter

A few examples on how to modify various parameters in the JavaScript API. Also see Control the path that’s sent to GoatCounter.

Custom path and referrer

A basic example with some custom logic for path:

<script>
    window.goatcounter = {
        // The passed value is the default.
        path: function(p) {
            // Don't track the home page.
            if (p === '/')
                return null

            // Remove .html from all other page links.
            return p.replace(/\.html$/, '')
        },
    }
</script>
<script data-goatcounter="https://s.jarv.org/count"
        async src="//s.jarv.org/count.js"></script>

Setting the endpoint in JavaScript

Normally GoatCounter gets the endpoint to send pageviews to from the data-goatcounter attribute on the <script> tag, but in some cases you may want to modify that in JavaScript; you can use goatcounter.endpoint for that.

For example, to send to different sites depending on the current hostname:

<script>
    var code = '';
    switch (location.hostname) {
    case 'example.com':
        code = 'a'
        break
    case 'example.org':
        code = 'b'
        break
    default:
        code = 'c'
    }
    window.goatcounter = {
        endpoint: 'https://' + code + '.goatcounter.com/count',
    }
</script>
<script async src="//s.jarv.org/count.js"></script>

Note that data-goatcounter will always override any goatcounter.endpoint, so don’t include it!

And remember to do this before the count.js script is loaded, or call window.goatcounter.count() manually.
