Creating an app shell and a default "No internet connection page" fallback

[ivandotv]

This package does a great job of caching the routes, however, in a true PWA we also need an offline mode. So when the user is offline and it navigates to a page that is not cached it should display something.
There is a great article about it on web fundamentals site.
So basically we need a default fallback for every route that is not cached.
A great example of this functionality is https://dev.to/ if you install this site as PWA , switch your phone to airplane mode, and try to refresh the app or navigate somewhere, it will show the default fallback page instead of the default browser "no internet connection" page.

Any ideas?

Sure, the feature is implemented.

To get started simply add a /_offline page such as pages/_offline.js or pages/_offline.jsx or pages/_offline.ts or pages/_offline.tsx. Then you are all set! When the user is offline, all pages which are not cached will fallback to '/_offline'.

This feature wasn't available when I asked the question :)
Great example, thank you for all your hard work.
