I really like the new FetchLater API - it doesn’t just keep a request alive after a page is gone like Beacon API does, but it also handles when to send it. Beacon leaves that to you, and no window event (beforeunload, pagehide, etc.) covers all cases - e.g. mobile minimizing suspends it. Plus, you can finally send JSON with application/json instead of text/plain. And it's easier to debug too! 🥳
Would love to see it making an appearance in Firefox and WebKit too, @jaffathecake @jensimmons ❤️
