Google Analytics integration for mithril

mithril-ga.js

var m = require('mithril');

var _mroute = m.route;

var type = {}.toString;

m.route = function(arg0, arg1){
  var res = m_route.apply(this, [].slice.call(arguments));
  if (type.call(arguments[0]) === '[object String]' || (arguments.length === 3 && type.call(arg1) === '[object String]')) {
    ga('send', 'pageview', _mroute());
  }
  return res;
};

m.route.strategy = _mroute.strategy;

per google's recommendation (https://developers.google.com/analytics/devguides/collection/analyticsjs/single-page-applications#tracking_virtual_pageviews), the ga portion should be:

ga('set', 'page', _mroute());
ga('send', 'pageview');
