Offline Page to be used in PWA

Describe the feature

Build process should be able to generate an offline page e.g. offline.html similar to index.html or 200.html page that is built when ssr is false. This offline page can be used by PWA / Service Worker so that application may fallback to SPA when user is offline.

Yes, it makes sense, pre-caching all routes should be an option to turn on/off. But PWAs that are published in the PlayStore for instance should behave exactly like native apps, meaning all routes should work offline, not only the ones that were visited. But it’s a different use case from yours I think.

Check out my example https://www.hom.wang

It appears you are caching all pages a user visits but that is not what we want to do since it will make only a few pages to work. For e.g. a user visits page A then it would can be used offline but page B won’t work.

We want to provide an entire offline SPA experience if a user is offline using workbox offline fallback. There might be a few sections which won’t work offline but we can still make a large part work in our use case.
