Angular SwUpdate activated deprecation

Question

In my angular project I have this kind of code:

this.swUpdate.available.subscribe(() => {
  ...
});

It work fine but gives me the warning about activated being deprecated.

What should I do to fix this warning?

Answer 1

I believe activated and activateUpdate() are different things. You call activateUpdate(), then when it's done, activated happens.

Furthermore, activated and available are definitely different things (your question references both). available means an update is detected; activated means it's been installed.

According to the docs (https://angular.io/api/service-worker/SwUpdate), the replacement for available is:

import {filter, map} from 'rxjs/operators';
// ...
const updatesAvailable = swUpdate.versionUpdates.pipe(
  filter((evt): evt is VersionReadyEvent => evt.type === 'VERSION_READY'),
  map(evt => ({
    type: 'UPDATE_AVAILABLE',
    current: evt.currentVersion,
    available: evt.latestVersion,
  })));

Answer 2

You must change activated to activateUpdate() and treat it as Promise:

this.swUpdate.activateUpdate().then(() => {
 ...
});
