Problem

The PWA takes longer to open than it needs to because we're not taking advantage of offline-caching of pages.

Solution

Get the site to work well offline and use the service worker's ability to cache requests to cache pages.

  • Take extra care to make sure that the site still reloads when a new version is released and the old cache is invalidated
  • Don't cache file attachments from chat

This sounds like something we could use the fetch event (in the SW) along with the Cache API. The Cache API is pretty low-level, so we need to handle things like expiration manually.

I think that this should be simple enough to work on (maybe tomorrow?). It should be ready for either this upcoming release or the one following.

ETA: This could also be the stepping stone for adding assent signing. My recommendation is to proceed with this issue as originally described (i.e., as a simple cache), but we could later build on this to sign and verify signatures.
