Window: sharedStorage property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
The global read-only sharedStorage property returns the WindowSharedStorage object for the current origin. This is the main entry point for writing data to shared storage using the Shared Storage API.
Note:
sharedStorage is not available inside workers. It is implemented by Window and is also available in shared storage worklets (see SharedStorageWorkletGlobalScope.sharedStorage, which returns WorkletSharedStorage).
Value
A WindowSharedStorage object instance.
Examples
window.sharedStorage
.set("ab-testing-group", "0")
.then(() => console.log("Value saved to shared storage"));
