An interesting proposal from Jake on a different way of defining how service worker fetch events could be handled under various conditions. For now, I have no particular opinion on it. I’m going to let this stew in my mind for a while.
GitHub - GoogleChromeLabs/quicklink: ⚡️Faster subsequent page-loads by prefetching in-viewport links during idle time
This looks like a very handle little performance-enhancing script: it attempts to prefetch some links, but in a responsible way. It won’t do any prefetching on slow connections or where data saving is enabled, and it only prefetches when the browser is idle.
I’m going to have to read through this article by Jake a few times before I begin to wrap my head around this background fetch thing, but it looks like it would be perfect for something like the dConstruct Audio Archive, where fairly large files can be saved for offline listening.
This is a really good use-case for cancelling fetch requests: making API calls while autocompleting in search.
A good hands-on introduction to service workers from Mariko.
A step-by-step guide to building progressive web apps. It covers promises, service workers, fetch, and cache, but seeing as it’s from Google, it also pushes the app-shell model.
This is a handy resource but I strongly disagree with some of the advice in the section on architectures (the same bit that gets all swoonsome for app shells):
Start by forgetting everything you know about conventional web design, and instead imagine designing a native app.
Avoid overly “web-like” design.
What a horribly limiting vision for the web! After all that talk about being progressive and responsive, we’re told to pretend we’re imitating native apps on one device type.
What’s really disgusting is the way that the Chrome team are withholding the “add to home screen” prompt from anyone who dares to make progressive web apps that are actually, y’know …webby.
This one is definitely for service worker nerds only. I’ve been trying to get my head around this idea of “foreign fetch” which allows third parties to install service workers—could be handy for sites with APIs like Huffduffer and The Session. This article does a good job of explaining the somewhat tangled process.

More details on DNS prefetching, page prefetching and, controversial, page pre-rendering.
