on Safari, unload and beforeunload events can't make segment request

[EDalSanto]

Having same issue as this person here . In short: Segment requests are async and Safari does not wait for async requests when unloading the page, so we lose events about our users. Only workaround is the Beacon API which is not supported by all browsers yet.

Has anyone else encountered this issue?

The requests must be async otherwise your users will have a poor customer experience. We've added persistent queues for this reason (segment-integrations/analytics.js-integration-segmentio@aae60a4), this is currently being tested behind a flag.

[EDalSanto]

So it's been tested with scenarios like I mentioned?

What's the easiest way to integrate it into our normal flow?

[f2prateek]

The queue perissts events to local storage so that when the user revisits, any previously failed requests will be retried rather than being lost. The only alternative to this is to use the beacon API, but browser compatibility is fairly limiting as you mentioned.

Is there a problem with using feature detection to see if Navigator.sendBeacon is available and defaulting to that and then falling back to XMLHttpRequest when its not there?

[f2prateek]

Sorry for the delay - we had considered doing that originally (segment-integrations/analytics.js-integration-segmentio@2801ef5), but ultimately decided against it for various reasons.

If you'd like to beta test the retry queue functionality (the one in segment-integrations/analytics.js-integration-segmentio@aae60a4), please reach out to our support team via http://segment.com/contact and they can get you setup.

@f2prateek Hi, I am looking to try the retry queue functionality, do I still need to contact the support team for this to be enabled? If so, I go to Contact Us -> Tech Support-> Technical Support, I see a contact form, but no where to input my contact info, how will the support contact me about my question, do I need to be logged in?

Hello @f2prateek I know it's been a long time since you left the comment, but if you still remember, can you help me understand what the reasons were for you to decide against sendBeacon?

@eunjae-lee This feature would be great to send a final message to segment that the app is closing.
