Update to 3.5.3 and PouchDB

Ionic Framework ionic-v3

Since the update to Ionic 3.5.3 and app-scripts 2.0.2 today, I’m getting the following error when using PouchDB:

ERROR Error: Uncaught (in promise): TypeError: __WEBPACK_IMPORTED_MODULE_1_pouchdb__ is not a constructor

Do you know, what’s the problem?

Same problem here. I changed the import statement from:

import * as PouchDB from 'pouchdb';

to

import PouchDB from 'pouchdb';

and it worked again.

Probably caused by the upgraded webpack now used in app-scripts.

Thank you. This was the solution for me.
