Async Operations Inside Indexeddb Cursor

I'm using indexedDB Promised library to convert the indexedDB API to promises. Looks like by the time my fetch is completed my indexed db transaction is no longer active. I'm gues

Solution 1:

You cannot do async operations in the middle of indexedDB operations. An IDBTransaction will automatically timeout if it does not detect any pending requests when it reaches the end of the current iteration of the JavaScript event loop. An async operation introduces a pause, so later requests that bind after the pause are bound too late, because by that time the transaction timed out and ended. Transactions are intended to be short lived, because a readwrite mode transaction can potentially lock up an object store for its entire duration, leading to serious blocking issues.

To work around this, do all of your async work either before or after the transaction, not in the middle of it. Or use two separate transactions, if data integrity is not an issue.
