Prototype: CookieStore API
- https://groups.google.com/a/mozilla.org/g/dev-platform/c/OkoMESRn_uc
- We plan to land a prototype that diverges from the official spec by the following points:
- 1. Only cookie names and values are shared via CookieStore.get()/getAll() methods. In this way, we do not expose more than what document.cookie already offers.
- 2. We don't implement the CookieStoreManager and the ServiceWorkerGlobalScope.oncookiechange event handler, with its ExtendableCookieChangeEvent event because we don't want to spawn ServiceWorkers at any cookie change
- 3. Following up on the previous point, CookieStore.onchange event handler is also exposed to ServiceWorkers.
