DeleteDB should call Close()

[wparad]

DeleteDB always gets blocked because the database is never closed. It should automatically be closed on Delete.

Otherwise something like this is necessary:

unwrap(await db).close();
await new Promise(resolve => setTimeout(resolve, 10000));

const deleteAsync = deleteDB(databaseName, {
    blocked(blockedVersion, blockedEvent) {
          logger.error({ title: 'Database blocked from being deleted', blockedVersion, blockedEvent });
    }
}

Why not just db.close()?

and why the wait? db is not intrinsically a promise, right? If you do const db = await openDB(...), db is a IDBP, not a Promise for an IDBP.

This works for me:

const db = openDB(.., {
  blocked: () => db.close()
})

...

deleteDB(db)

I don't believe the types supported that. But I can always check again.

And close is async, and I believe blocked doesn't handle promises well. But something might have changed.

So how should I ascertain I can delete the database?

Is close async? Close on plain indexeddb doesn't have event handlers right? If so, why would it be async in this library?
