Instance Methods

serviceWorker.isDestroyed() Experimental

Returns boolean - Whether the service worker has been destroyed.

serviceWorker.send(channel, ...args) Experimental

• channel string
• ...args any[]

Send an asynchronous message to the service worker process via channel, along with arguments. Arguments will be serialized with the Structured Clone Algorithm, just like postMessage, so prototype chains will not be included. Sending Functions, Promises, Symbols, WeakMaps, or WeakSets will throw an exception.

The service worker process can handle the message by listening to channel with the ipcRenderer module.

serviceWorker.startTask() Experimental

Returns Object:

• end Function - Method to call when the task has ended. If never called, the service won't terminate while otherwise idle.

Initiate a task to keep the service worker alive until ended.
