IDBTransaction: durability property
Baseline
2024
Newly available
Since May 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The durability read-only property of the 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 IDBDatabase.transaction().
Value
Any of the following literal 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.
