SharedStorage: clear() method
Deprecated
To be removed
This feature is pending removal from browsers. Using it now may lead to broken functionality in future updates. Following the announcement that Chrome will maintain its current approach to third-party cookies, Chrome decided to withdraw certain Privacy Sandbox features including the shared storage.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The clear() method of the SharedStorage interface clears the current origin's shared storage, removing all data from it.
Syntax
clear()
Parameters
None.
Return value
A Promise that fulfills with undefined.
Exceptions
- The
Promiserejects with aTypeErrorif:- The database was not cleared successfully due to shared storage not being available (for example it is disabled using a browser setting).
- The calling site does not have the Shared Storage API included in a successful privacy sandbox enrollment process.
- In the case of
WorkletSharedStorage, thePromiserejects with aTypeErrorif the worklet module has not been added withSharedStorageWorklet.addModule().
Note:
In the case of WindowSharedStorage, if the clear() operation doesn't successfully write to the database for a reason other than shared storage not being available, no error is thrown — the operation still fulfills with undefined.
Examples
window.sharedStorage.clear().then(() => console.log("Shared storage cleared"));
