It's been a while since I've guest written on another website. I normally find myself writing solely for this site, but I recently teamed up with Nicolás Bevacqua and his fun blog site Ponyfoo.com. If you've not heard of ponyfoo before, I thoroughly recommend checking it out.
The guest article dives into the Background Sync API using Service Workers. Don't worry if you've never used Service Workers before - the article goes through the basics and includes a working example for you to test with.
The article is live and I'd love your feedback. Please let me know if you end up implementing this for yourself!
