Stuff I wish I'd known sooner about service workers
I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.
I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.
Use Canary for development instead of Chrome stable
Chrome 51 has some pretty wild behaviour related to
console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
