IronRouter's onAfterAction called multiple times per page (Google Analytics problems)

[Eliezer Steinbock]

Hi,

Iron Router's onAfterAction is called multiple times per page and this causing me problems with Google Analytics. I log my analytics using the technique used in the Telesc.pe project, which looks as follows:

Router.onAfterAction(analyticsRequest);

analyticsRequest = function() {

  noOfAnalyticsRequests++;

  console.log('analyticsRequest');

  

  // Google Analytics

  if (typeof window.ga !== 'undefined'){

    ga('send', 'pageview', {

      'page': window.location.pathname

    }); 

  }

}

The problem is that each page request is running onAfterAction multiple times per page. How can I stop this and thereby accurately see my Analytics results?

On thing I did that has helped is remove the multiply:iron-router-progress package from my project and now onAfterAction is only being called once or twice per page instead of 3 times per page. Is there a way to completely get rid of the problem? And is there a way to track analytics accurately while still using multiply:iron-router-progress?

Thanks

Hi there.

Probably you have some reactive in you action or before action. This cause the entire route to re-run.

Thanks. I'll have to take a closer look. There's nothing obviously reactive in my routes. It might be a global onbeforeaction for my router. Is there a way to use iron router progress without it rerunning routes?

You can try to use the onRun hook.

From https://github.com/iron-meteor/iron-router/blob/devel/Guide.md#available-hook-methods:

• onRun: Called when the route is first run. It is not called again if the route reruns because of a computation invalidation. This makes it a good candidate for things like analytics where you want be sure the hook only runs once. Note that this hook won't run again if the route is reloaded via hot code push.
