Cross-origin Service Workers: Experimenting with Foreign Fetch | Web Updates - Google Developers

This one is definitely for service worker nerds only.

minimum interesting service worker

An interesting idea from Tantek for an offline page that links off to an archived copy of the URL you’re trying to reach—useful for when you’re site goes down (though not for when the user’s internet connection is down).

How to make MPAs that are as fast as SPAs | Go Make Things

The headline is a little misleading because if you follow this advice, your multi-page apps will be much much faster than single page apps, especially when you include that initial page load of a single page app.

Here’s a quick high-level summary of what I do…

  1. Serve pre-rendered, mostly static HTML.
  2. Inline everything, including CSS and JavaScript.
  3. Use mostly platform-native JavaScript, and as little of it as possible.
  4. Minify and gzip all the things.
  5. Lean heavily on service workers.

That’s an excellent recipe for success right there!
