trait ServiceWorkerContainer extends EventTarget
The ServiceWorkerContainer interface of the ServiceWorker API exposes the ServiceWorkerContainer. register(scriptURL, scope[, base]) method used to register service workers, and the ServiceWorkerContainer. controller property used to determine whether or not the current page is actively controlled.

addEventListener[T <: Event](type: String, listener: Function1[T, _], options: EventListenerOptions): Unit
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on.
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).
This implementation accepts a settings object of type EventListenerOptions.

controller: ServiceWorker
The ServiceWorkerContainer.controller read-only property of the ServiceWorkerContainer interface returns the ServiceWorker whose state is activated (the same object returned by ServiceWorkerRegistration.active).
The ServiceWorkerContainer.controller read-only property of the ServiceWorkerContainer interface returns the ServiceWorker whose state is activated (the same object returned by ServiceWorkerRegistration.active). This property returns null if the request is a force refresh (Shift + refresh) or if there is no active worker.

dispatchEvent(evt: Event): Boolean
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order.
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().

Gets a ServiceWorkerRegistration object whose scope URL matches the document URL.
Gets a ServiceWorkerRegistration object whose scope URL matches the document URL. If the method can't return a ServiceWorkerRegistration, it returns a Promise.

getRegistrations(): Promise[Array[ServiceWorkerRegistration]]

val
oncontrollerchange: Function1[Event, _]
The oncontrollerchange property of the ServiceWorkerContainer interface is an event handler fired whenever a controllerchange event occurs — when the document's associated ServiceWorkerRegistratin acquires a new ServiceWorkerRegistration.active worker.
-
val
onmessage: Function1[MessageEvent, _]
The onmessage property of the ServiceWorkerContainer interface is an event handler fired whenever a message event occurs — when incoming messages are received to the ServiceWorkerContainer object (e.g., via a MessagePort.postMessage() call).

ready: Promise[ServiceWorkerRegistration]
The ready read-only property of the ServiceWorkerContainer interface defines whether a service worker is ready to control a page or not.
The ready read-only property of the ServiceWorkerContainer interface defines whether a service worker is ready to control a page or not. It returns a Promise that will never reject, which resolves to a ServiceWorkerRegistration with an ServiceWorkerRegistration.active worker.

def
register(scriptURL: String, options: ServiceWorkerRegistrationOptions = js.native): Promise[ServiceWorkerRegistration]
Creates or updates a ServiceWorkerRegistration for the given scriptURL.
Creates or updates a ServiceWorkerRegistration for the given scriptURL. If successful, a service worker registration ties the provided script URL to a scope, which is subsequently used for navigation matching. If the method can't return a ServiceWorkerRegistration, it returns a Promise. You can call this method unconditionally from the controlled page, i.e., you don't need to first check whether there's an active registration.
