IDBTransaction: durability property

{{securecontext_header}}{{APIRef("IndexedDB")}}

The durability read-only property of the {{domxref("IDBTransaction")}} interface returns the durability hint the transaction was created with. This is a hint to the user agent of whether to prioritize performance or durability when committing the transaction.

The value of this property is defined in the options.durability parameter when creating a transaction using {{domxref("IDBDatabase.transaction()")}}.

Value

Any of the following literal {{jsxref('String', 'strings')}}:

• "strict"
  • : The user agent may consider that the transaction has successfully committed only after verifying that all outstanding changes have been successfully written to a persistent storage medium.
• "relaxed"
  • : The user agent may consider that the transaction has successfully committed as soon as all outstanding changes have been written to the operating system, without subsequent verification.
• "default"
  • : The user agent should use its default durability behavior for the storage bucket. This is the default for transactions if not otherwise specified.
