When offline, the start page doesn't load because of Google Analytics

rkorach commented 12 years ago

We need to make a test to see if we are internet connected, and disable analytics if so, or find a way to queue analytics calls until internet is accessed. (I don't know if it is possible, but we'll have to investigate) Two possibilities:

Chrome has a specific "allow offline mode" for a few apps, like offline gmail for instance. This means it already checks internet connection. We could find out if we can get this info.
Use a js/ajax snippet to test connection.

Other problems with offline are:

images won't load (anything doable with cache?)
embed elements won't load (can we display a preview picture with a note?)

It's ok to leave background.html since people may read some pre-loaded articles offline, and we'll be able to gather info.

Chrome offline mode is for apps, not extensions, so I don't think we can use this to detect offline state.

navigator.onLine seems to work (http://www.toutjavascript.com/reference/reference.php?iref=68)

However, it is strongly argued that it is a mess. http://stackoverflow.com/questions/3181080/how-to-detect-online-offline-event-cross-browser

It seems that with the new class of ga.js there is no error when offline. I don't know exactly why. @HadrienR could you make some tests to check that analytics are really working with a internet connexion. Change bAnalytics to true in config.js and check that data are realy sent. I am not sure I have access to analytics account. Thanks.

You do have access (even with your @ct.com) but I can check for you.

I don't think it works. This is what the console tells me when I delete a sticker in "Edit". (see attachment)
