Error: NotFoundError: DOM IDBDatabase Exception 8 on iOS8 about dexie.js HOT 5 CLOSED

it maybe related to this safari issue:

https://bugs.webkit.org/show_bug.cgi?id=136937

and its caused by:
Dexie (line 537):
adjustToExistingIndexNames(globalSchema, idbdb.transaction(idbdb.objectStoreNames, READONLY));

from dexie.js.

As outlined in https://bugs.webkit.org/show_bug.cgi?id=136937 this is only an issue on iOS if multiple stores are passed to idbdb.transaction().

The following change will remove the error on iOS but only if the database contains a single store. Databases with multiple stores will still throw an error.

Change (~ line 531):

else if (idbdb.objectStoreNames.length > 0)
    adjustToExistingIndexNames(globalSchema, idbdb.transaction(idbdb.objectStoreNames, READONLY));

To:

else if (idbdb.objectStoreNames.length > 0) {
    var storeNamesHack = idbdb.objectStoreNames.length > 1 ? idbdb.objectStoreNames : idbdb.objectStoreNames.item(0);
    adjustToExistingIndexNames(globalSchema, idbdb.transaction(storeNamesHack, READONLY));
}

Note that using an array that contains a single value will also work:

else if (idbdb.objectStoreNames.length > 0) {
    var storeNamesHack = idbdb.objectStoreNames.length > 1 ? idbdb.objectStoreNames : [idbdb.objectStoreNames.item(0)];
    adjustToExistingIndexNames(globalSchema, idbdb.transaction(storeNamesHack, READONLY));
}

Edit: Changed .item() to .item(0)

Seems like you've found a new IndexedDB bug in iOS 8. Could you provide a live example and file a bug on WebKit? :)

Oh nevermind, I see that this IS the same bug. What you're saying is that there's a workaround. (If there's only one store, open using 'databasename' rather than ['databasename'].)

I made a live test case anyway, just for kicks: http://bl.ocks.org/nolanlawson/1d407ac013d92bf998cb

Solved. See comments on
