clear()

Clears the current origin's shared storage, removing all data from it.

delete()

Deletes an existing key-value pair from the current origin's shared storage.

set()

Stores a new key-value pair in the current origin's shared storage or updates an existing one.

Examples

js
window.sharedStorage
  .set("ab-testing-group", "0")
  .then(console.log("Value saved to shared storage"));
