Is there a way to listen to the close event?

[jsrilapan]

Hello there, I'm looking for a way to catch a close event when the user explicitly deletes the database.
For example, user clears browsing data or just deletes database from the Chrome dev tools.

The native IDBDatabase interface has this onclose event handler. It will fired when the situations above occurred so I was wondering if there is a possible way that Dexie can listen or expose that event too?

Thanks in advance.

Dexie should definitely have its own on('close') API (PR welcome!) but for now you can do the following:

const db = new Dexie("dbname");
db.on('ready', () => {
  db.backendDB().onclose = event => {
    myAppShowAlert('The database "' + db.name + '" has unexpectedly closed.');
  };
});

Thanks for your respond, I will make a PR when it's ready.
