Based from this blog, a PWA should be able to do some work offline using service workers.
Service workers essentially act as proxy servers that sit between web applications, the browser, and the network (when available). They are intended, among other things, to enable the creation of effective offline experiences, intercept network requests and take appropriate action based on whether the network is available, and update assets residing on the server.
Check this Offline Storage for Progressive Web Apps documentation.
- For the network resources necessary to load your app while offline, use the Cache API (part of service workers).
- For all other data, use IndexedDB (with a promises wrapper).
