CookieChangeEvent()

Creates a new CookieChangeEvent.

Instance properties

This interface also inherits properties from Event.

CookieChangeEvent.changed Read only

An array listing all newly-created cookies. Note that this will exclude cookies which were created with an expiry date in the past, as these cookies are immediately deleted.

CookieChangeEvent.deleted Read only

An array listing all cookies which were removed, either because they expired or because they were explicitly deleted. Note that this will include cookies which were created with an expiry date in the past.

Instance methods

This interface also inherits methods from Event.

Examples

In this example when the cookie is set, the event listener logs the event to the console. This is a CookieChangeEvent object with the changed property containing an object representing the cookie that has just been set.

cookieStore.addEventListener("change", (event) => {
  console.log(event);
});
const oneDay = 24 * 60 * 60 * 1000;
cookieStore.set({
  name: "cookie1",
  value: "cookie1-value",
  expires: Date.now() + oneDay,
  domain: "example.com",
});
