Cache then network support

[simonfl3tcher]

It would be good to add support for the cache then network approach. At the moment this is completely unsupported. The repository uses the offline-plugin for webpack. In an ideal world we would carry on using this as it is built for this specific problem.

The approach is open for discussion.

If I may ask why offline-plugin over say sw-precache?

[simonfl3tcher]

@jasan-s I chose offline-plugin as it worked well with webpack out of the box, the main aim of this app was to provide a quick and simple way to create a PWA with React. However, if we feel that sw-precache is a better option moving forward, I am more than happy to consider it. Let me know what your thoughts are.

I personally have not used this offline-plugin, thus i was curious. But it does seem like its quite easy to setup. I use sw-precache-webpack-plugin. Does the plugin provide runtime caching of url patterns fetched over network? or just the external local files not available during build.

Since I have vendor common chunk(react, react dom), I use MD5 hash to limit SW Update to just the app chunks.

I am not sure sure to be honest, something we need to look into, feels like something it would support though.
