ReadonlyscriptReturns the ServiceWorker serialized script URL defined as part of ServiceWorkerRegistration. Must be on the same origin as the document that registers the ServiceWorker.
ReadonlystateThe state read-only property of the ServiceWorker interface returns a string representing the current state of the service worker. It can be one of the following values: parsed, installing, installed, activating, activated, or redundant.
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
Optionaloptions: boolean | AddEventListenerOptionsThe addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
Optionaloptions: boolean | AddEventListenerOptionsThe dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
The postMessage() method of the ServiceWorker interface sends a message to the worker. The first parameter is the data to send to the worker. The data may be any JavaScript object which can be handled by the structured clone algorithm.
Optionaloptions: StructuredSerializeOptionsThe removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
Optionaloptions: boolean | EventListenerOptionsThe removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.

The
ServiceWorkerinterface of the Service Worker API provides a reference to a service worker. Multiple browsing contexts (e.g., pages, workers, etc.) can be associated with the same service worker, each through a unique ServiceWorker object. Available only in secure contexts.MDN Reference
