Over the past few years I've built out this Astronomy Picture of the Day (APOD) Chrome/FF extension that shows an APOD as your new tab page. Just recently I've overhauled it with React to try and reign in the features I had built in Vanilla JS originally.
Anyway, with these updates I've added a service worker to make it load as fast as possible and in case there are others here that really love the APOD I wanted to share.
