IDBTransaction.durability

Draft: This page is not complete.

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.

Syntax

var transactionDurability = idbTransaction.durability;

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.
