SharedStorage: clear() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The clear() method of the SharedStorage interface clears the current origin's shared storage, removing all data from it.

Syntax

clear()

Return value

A Promise that fulfills with undefined.

Exceptions

The Promise rejects with a TypeError if:
- 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, the Promise rejects with a TypeError if the worklet module has not been added with SharedStorageWorklet.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"));
