rack-chartbeat
Rack middleware to automatically include Chartbeat embed codes.
Example
require "rack/chartbeat"
use Rack::Chartbeat, uid: 12345, domain: "example.com"
Including this in the config.ru file of your Rack application will automatically inject the corresponding JavaScript into the <head> and <body> of your HTML, respectively:
<script type="text/javascript">var _sf_startpt=(new Date()).getTime()</script>
<script type="text/javascript">
var _sf_async_config={uid:12345,domain:"example.com"};
(function(){
function loadChartbeat() {
window._sf_endpt=(new Date()).getTime();
var e = document.createElement('script');
e.setAttribute('language', 'javascript');
e.setAttribute('type', 'text/javascript');
e.setAttribute('src',
(("https:" == document.location.protocol) ? "https://a248.e.akamai.net/chartbeat.download.akamai.com/102508/" : "http://static.chartbeat.com/") +
"js/chartbeat.js");
document.body.appendChild(e);
}
var oldonload = window.onload;
window.onload = (typeof window.onload != 'function') ?
loadChartbeat : function() { oldonload(); loadChartbeat(); };
})();
</script>
