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.

We dropped Lerna from our monorepo architecture in PouchDB 6.0.0. I got a question about this from @reconbot, so I thought I'd explain our reasoning.
First off, I don't want this post to be read as "Lerna sucks, don't use Lerna." We started out using Lerna, but eventually outgrew it because we wrote our own custom thing. Lerna is still a great idea if you're getting started with monorepos (monorepi?).
Backstory:
There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.
brew install ffmpeg
apt install ffmpeg
