Calling analytics.track() calls all the enabled providers. This is usually good, but in some cases, there are tracking request I'd like to forward to google and and not to mixpanel or vice a versa, so what I'd like is for analytics.track() to provide a way of (optionally) specifying which providers to use with this call and which not.
I'd imagine the API such as:

analytics.track(eventName, trackingData, opt_callback, opt_providers)

Where providers could be a blacklist or a whitelist.
For example:

{ga: true} // Use only GA
{ga: false} // Use all others except GA.

I'd like to see support for http://getsentry.com/welcome/ for JS error tracking
http://raven-js.readthedocs.org/en/latest/usage/index.html#tracking-authenticated-users

this would allow people to use ready and still turn off integrations via the interface without errors.

Functions like registerOnce (which we use to track landing pages) are missing from the Segment.io API. This would be fine if we could get reliable access to the Mixpanel object. Using the loaded version of analytics.js there arn't any callbacks when a library is loaded, nor are any function calls buffered.

This is the only blocker to us using Segment.io right now.

https://github.com/segmentio/analytics.js/blob/master/src/providers/gosquared/gosquared.js#L47

it is the same problem where GoSquared needs identify before the initialize is called...

we need the same cookie solution @calvinfo

In some cases I'd like to call _gat._getTrackerByName()._trackEvent directly, rather than going through _gaq.push(['_trackEvent', ...])
_gaq is asynchronous, so when I want to send something right now I prefer calling _gat. For example when a user navigates away from my page, I want to make the best effort to sent some data to ga before the page is gone and from my testing it seems that gat gives us a better chance (although not guaranteed) to get the data across to google before the page is gone.

Does it make sense to add support for sync event like this?

they should have a short timeout so that the root page is never blocked by a provider not returning fast enough

When attempting to use Analytics.js with Mixpanel on IE 8, the following error is thrown:

Version mismatch; please ensure you're using the latest version of the Mixpanel code snippet.

This does not occur on any other browser...

I'm curious to see if anyone's thinking about or working on support for either classic ga.js custom variables or new-school Google analytics.js custom dimensions and metrics with analytics.js. So far I've thought about three ways of doing it:

1. Hijack identify() -- GA doesn't accept personally identifiable data so we ignore the identifier and parse out specific properties (slot, category, value, and scope).. custom vars are used to segment users so I think there is some logic to this

2. Hijack track() -- setting a custom variable doesn't match the semantics of track very well to me, so I like this less, but it's conceivable

3. Either add a separate method for the provider or do it entirely out-of-band -- the dirty feeling I get when I think about this makes me sad and is what led me to options 1 and 2.

I must admit I haven't spent a lot of time on this, but I don't currently see an answer to it w/ analytics.js and I wanted to see if it seems appropriate and within the scope of the project, or if I should just pursue another course.

http://segmentio.github.com/analytics.js/ is still first in google for "analytics.js" -- I'm assuming it's out of date now, you should redirect it :)

would be nice if you hosted the new docs on github (are they?). for example, i see a mistake in the mixpanel page (since #60)

Personally I don't want the mixpanel name_tag to use the user_id, so it would be nice if there was a way to customize this. Possibly passing in a trait name into initialize to override the current behavior?

Mixpanel staff mentioned in their weekly webinar that identify() should be called ONLY after people.set()/people.increment() is called. See https://github.com/segmentio/analytics.js/blob/master/analytics.js#L1625.

I hope they'll weigh in on this issue.

that combines Mixpanel's and KISSmetrics's. If you know of any other provider that supports aliasing (or merging) accounts feel free to comment here

https://mixpanel.com/docs/integration-libraries/upgrading-the-javascript-library

a little trickier since they are sync. i think we'll require that their snippet is already on the page, but if it is well let you use our api to route to them

As explained in chat yesterday we use Fastspring.com for our shop, the push this as an "e-commerce" transaction into GA when somebody bought. Can you do the same?

    <script type="text/javascript">
        var _gaq = _gaq || [];
        _gaq.push(['_setAccount', 'UA-20537420-1']);
        _gaq.push(['_setAllowLinker', true]);
_gaq.push(['_addIgnoredRef', 'veodin.com']);

        _gaq.push(['_trackPageview']);
            _gaq.push(['_addTrans', 
'VEO130303-8530-26143',
'KeyRocket Store',
'0.00',
'',
'0.00',
'Berlin',
'',
'DE'
]);
_gaq.push(['_addItem', 
'VEO130303-8530-26143',
'KeyRocket Premium - One-time Payment',
'KeyRocket Premium',
'',
'0.00',
'1'
]);

            _gaq.push(['_trackTrans']);

        (function() {
            var ga = document.createElement('script'); 
            ga.type = 'text/javascript'; 
            ga.async = true;
            ga.src = "https://ssl.google-analytics.com/ga.js";
            var s = document.getElementsByTagName('script')[0]; 
            s.parentNode.insertBefore(ga, s);
        })();
    </script>   

I'd like to use analytics.js itself (rather than segment.io), but was wondering if you'd like to support a CDN'ed version of analytics.js without segment.io

I see from https://segment.io/close.io/setup/javascript/snippet that you have urls like https://d2dq2ahtl5zl1z.cloudfront.net/analytics.js/v1/x0cyzac/analytics.min.js (with a nice async loading snippet). Is there anywhere that doesn't require the segment.io api key?

https://github.com/segmentio/analytics.js/blob/master/src/providers/hubspot.js#L37

should be updated to a more complete/consistent check like

https://github.com/segmentio/analytics.js/blob/master/src/providers/customerio.js#L57

In the docs for identify I am unable to find any guidance for whether the method should be called once per userId (ever) or whether it is safe -- or even advisable -- to call it anytime a userId authenticates.

In a similar vein, if one calls identify multiple times for the same userId, but provides extra traits for the userId beyond those used on the first call, does that cause segment.io to view the userId as a new one?

I doubt someone will need all services on the same app, users will surely need other providers that aren't supported.

I think a better approach would be to break each adapter into its own file and create a method like analytics.register(providerId, adapter).

by splitting into separate files you don't need to care about file size, user will load only what they need.

Please fix 'Intercom' provider on line: https://github.com/segmentio/analytics.js/blob/master/src/providers/intercom/intercom.js#L41

I'm getting a weird error when I attempt to use analytics.js with KISSmetrics on IE 8:

_kmq is null or not an object

Some specifics:

• Error is being thrown when the kissmetrics js lib is loaded via _kms('//doug1izaerwt3.cloudfront.net/'+...);
• Right before that, but after the statement window._kmq = _kmq;, logging _kmq returns an object with no keys.
• Inside the dynamically loaded kissmetrics js lib, error is being thrown at: _kmq.push(["au"]). At that point, window._kmq is for some reason undefined.

I'm seeing an error when trying to load analytics.js later on, after the page has loaded. I have a function, loadAnalyticsJs which is called later on in the page execution, since we only want to track a small subset of page views.

// Function to lazy-load analytics.js
var loadAnalyticsJs = function() {
  var analytics=analytics||[];analytics.load=function(e){var t=document.createElement("script");t.type="text/javascript",t.async=!0,t.src=("https:"===document.location.protocol?"https://":"http://")+"d2dq2ahtl5zl1z.cloudfront.net"+"/analytics.js/v1/"+e+"/analytics.min.js";var n=document.getElementsByTagName("script")[0];n.parentNode.insertBefore(t,n);var r=function(e){return function(){analytics.push([e].concat(Array.prototype.slice.call(arguments,0)));};},s=["identify","track"];for(var i=0;i<s.length;i++)analytics[s[i]]=r(s[i]);},
  analytics.load("XXXXXXX");
};

// Example of usage that causes error
setTimeout(loadAnalyticsJs, 10000);

When this is used, I see this error in the console:

Uncaught TypeError: Cannot read property 'length' of undefined analytics.min.js:4

I haven't had the chance to look through the un-minified source for analytics.js yet, but I'm guessing this has something to do with inspecting the script tags on the page, and that analytics.js is assuming the presence of a script tag that loaded it?

for common actions like Signed Up and Billed

KISSmetrics and Mixpanel both support signup:
http://support.kissmetrics.com/apis/saas_events
https://mixpanel.com/docs/learn-the-features/retention-overview

that way we could start tying semantics to event names, so people can do cool things

Hi,

kudos for yuor great library.

I think that having standard name for provider's id key would simplify provider's abstraction.

Now we have:
for Google analytics -> trackingId
for Mixpanel -> token
for KISSmetrics -> apiKey
...

The standard way:
for Google analytics -> id
for Mixpanel -> id
for KISSmetrics -> id
...

Then every provider should change that key name accordingly to their apis.

http://support.google.com/analytics/bin/answer.py?hl=en&answer=2444872

How would you do it since you are using component to package the lib ?

For created and lastSeen, would be good to know if analytics.js is expecting a Date() object, a string in a certain format, or a unix timestamp

Hi, is Piwik support planned?

We use a GA with a wordpress plugin and I want to keep it that way because they have more features.

I still like to use segment.io > Google Analytics for all the custom events we do via .track()

Therefore I need to disable that pageviews are sent to GA via segment.io

(Thinking about it this might leed to GA being loaded twice, any ideas? :-/)

There's a track code sample right after the identify section.

The same code is repeated in the track section.

I'm having huge issues implementing analytics.js in a "smart" way using Backbone.

I have multiple main HTML layouts in my Rails application, and each of those layouts have a main Backbone view that has multiple nested Backbone view. Each of these apps needs to call the track function of analytics.js.

So I want to wrap my analytics object in a Backbone view that all these apps have access to. This view will also store information about the user, so each individual piece of code doesn't need to know these things.

However, I'm having huge problems with what I think is scoping issues. It looks like analytics.js must be initialized in the root document. If I initialize the code in a backbone view (changning a few things for scoping issues), I get this:

Uncaught TypeError: Cannot set property 'identify' of undefined
Uncaught TypeError: Cannot call method 'track' of undefined
Uncaught TypeError: Cannot read property 'length' of undefined 

Even if I instantiate the analytics object in root, and then pass a reference to a Backbone view, I'm getting errors when calling track:

Uncaught TypeError: Object #<g> has no method 'push'

Is there a way to make this library a little more suited for JS code that uses a JS framework to order things nicely? Does anyone have an example of how to do this?

there should be a way to monkey-patch and do some sort of AOP over the providers (eg. replace the methods to do some logging instead of actually calling the provider during development).

Would be nice to be able to pass config to olark.configure
https://www.olark.com/documentation

olark.configure('box.start_hidden', true);

behind a flag of course
