    • "strict"
      • : Cookies will only be sent in a first-party context and not be sent with requests initiated by third party websites.
    • "lax"
      • : Cookies are not sent on normal cross-site subrequests (for example to load images or frames into a third party site), but are sent when a user is navigating within the origin site (i.e., when following a link).
    • "none"
      • : Cookies will be sent in all contexts.

• partitioned

  • : A boolean indicating whether the cookie is a partitioned cookie (true) or not (false). See Cookies Having Independent Partitioned State (CHIPS) for more information.

Examples

In this example when the cookie is deleted the event listener logs the first item in the deleted property to the console. It contains an object representing the cookie that has just been deleted.

self.addEventListener("cookiechange", (event) => {
  console.log(event.deleted[0]);
});
