This gist is an ES module which provides functions to import and export data from an IndexedDB database as JSON. It's based on Justin Emery's indexeddb-export-import package, but applies some adjustments that reflect better on the current browser landscape (i.e. better developer ergonomics but no support for Internet Explorer).
For each of the provided functionalities, you need a connected IDBDatabase instance.
import { idb } from 'some-database'
