serviceworker.skipWaiting

[jakearchibald]

Allowing:

const reg = await navigator.serviceWorker.ready;
if (reg.waiting) {
  await reg.waiting.skipWaiting();
  location.reload();
}

Usecase: The new service worker has installed, I've shown a message to the user like "New version found. Update now?", which they have clicked.

Currently developers have to postMessage to the service worker for this behaviour.

It's also an opportunity for us to rethink when skipWaiting should resolve in this case. It could resolve once the service worker has begun activating.

F2F: lukewarm reception. If it's trivial, we can do it. "If it can live on the main window, it should".

Taking it one step further, it would be nice to be able to, from the active worker, call update() in a way that ensures the resulting installation will skipWaiting(). For instance:

registration.update({ skipWaiting: true });

Use case: a worker decides it's not in a good state and wants to force upgrade to the latest.

EDIT: I think the proposal of serviceworker.skipWaiting() is great on its own too.

According to #1303 (comment) linkedin wants this.
