Indexeddb SQLite Error: "No available storage method found" (iOS PWA)

[phonic]

Got the issue when running the ionic sample tab app as a browser pwa on iOS.

It also occurs in chrome iOS webview as well as on iphone safari browser.
The bug does not occur on Chrome Desktop or on Android.

The error log from the chrome console;

core.js:9110 ERROR Error: Uncaught (in promise): Error: No available storage method found.

As a workaround we uninstalled ionic-storage and are using dexie.js so far (which works without any problems)

it is really easy just :
add ‘localstorage’ to driverOrder
like this::
** IonicStorageModule.forRoot({**
** name: “Database”,**
** driverOrder: [“indexeddb”, “localstorage”]**
** }),**

Is localstorage enough if the user has storage disabled? Even if they don't, would 50MB be enough (Safari Limit). It is also synchronous and thread-blocking.

Perhaps in-memory storage should be used in this case:
