When creating a PWA it pays to think about the offline experience from the outset. This approach is often termed "offline-first design".
The Progressive Web Application entity includes the Offline Resources configuration, used to specify offline and online versions of resources. This can be used to specify forms with reduced-feature sets that can be displayed when the PWA is offline. Offline versions of forms should not rely on calls to the Verj.io Server or the loading of external resources; instead, cached content and local storage should be used to display previously fetched content.
For example, a form may fetch and display recent posts in an online forum. These posts could be cached in local storage each time they are retrieved. An offline version of the form would not attempt to fetch new posts and display the cached posts instead.
