Use of navigator `sendBeacon`?

See original GitHub issue

Hi,

Would you consider using navigator.sendBeacon when available (modern browsers) rather than xhr requests? The advantages are:

offline support (events are queued if loss of connectivity)
execution in a worker thread
page unloads doesn’t cancel in-flight requests

Thanks

@joshunger and others, sendBeacon is now available in beta as of SDK version 8.5.0. There are notes on how to use it here, and let me know if you encounter any issues with it.

@joshunger theoretically, one could do that by making a fetch request directly to amplitude’s HTTP endpoint from the browser inside a navigator.sendBeacon call.

However, this feature is actively being worked on now, and will be available in the JS SDK by the end of next week at the latest. So if you’re able to wait it will be ready natively soon
