IDBTransaction: commit() method

BaselineWidely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.

Note: This feature is available inWeb Workers.

Thecommit() method of theIDBTransaction interface commits the transaction if it is called on an active transaction.

Note thatcommit() doesn't normallyhave to be called — a transaction will automatically commit when all outstanding requests have been satisfied and no new requests have been made.commit() can be used to start the commit process without waiting for events from outstanding requests to be dispatched.

If it is called on a transaction that is not active, it throws anInvalidStateErrorDOMException.

Syntax

commit()

InvalidStateErrorDOMException: Thrown if the transaction state is not active.
