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.

~~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.~~

enough.css

enough.css is a tiny CSS style sheet with most of the styling you'll need for that blog of yours. It moved to https://github.com/jeffkreeftmeijer/enough.css

Update package.json, set version to a prerelease version, e.g. 2.0.0-rc1, 3.1.5-rc4, ...
Run npm pack to create package
Run npm publish <package>.tgz --tag next to publish the package under the next tag
Run npm install --save package@next to install prerelease package
