A way to listen to event being sent

[iipanda]

I'm trying to track link clicks:
Swetrix.track({ ev: 'cta_link_click' });
The issue with this is the navigation happens before the event finishes sending and thus the request fails with NS_BINDING_ABORTED status without being sent. The solution would be returning a promise from the Swetrix.track function or accepting a callback to know when the event has finished sending and proceed with the navigation then.

I can implement this functionality I just wanted to make sure this contribution would be welcome.

I'm also noticing you are using XMLHttpRequest to send requests instead of the fetch API. Is there any particular reason? If there is no need to keep this I would replace it with fetch since XHR would require me to wrestle with callbacks instead of simply returning a promise.

Hi @iipanda, there's no reason to use XMLHttpRequest, feel free to rewrite it to Fetch and return a promise in the track method
