Service Worker Management

[esheehan-gsl]

Problem

The service worker speeds up the application a great deal, but there are two problems:

1. We serve stale application assets while we update in the background, sometimes resulting in strange UI behavior until the next page load
2. Data is cached indefinitely, so if the format changes and someone has a stale copy of the data, they never get the updated version

Solution

We should detect when the application assets have changed. If we load new CSS or JS in the background, we should notify users that they should refresh to get the latest version.

We also need to provide controls that tell users what data is available in the cache and allow them to either refresh or delete that data.
