trait ServiceWorkerGlobalScope extends raw.EventTarget with WorkerGlobalScope

The ServiceWorkerGlobalScope interface of the ServiceWorker API represents the global execution context of a service worker.

Developers should keep in mind that the ServiceWorker.state is not persisted across the termination/restart cycle, so each event handler should assume it's being invoked with a bare, default global state.

Once successfully registered, a service worker can and will be terminated when idle to conserve memory and processor power. An active service worker is automatically restarted to respond to events, such as ServiceWorkerGlobalScope.onfetch or ServiceWorkerGlobalScope.onmessage.

Additionally, synchronous requests are not allowed from within a service worker — only asynchronous requests, like those initiated via the fetch() method, can be used.
