ember-service-worker-update-notify

Adds a service-worker-update-notify service and <ServiceWorkerUpdateNotify />component which displays a reload link if the service-worker has found an update.

Usage

Using the component

The component will show a message to the user when the availability of an updatehas been detected. Overwrite the default message using the component in block form:

<ServiceWorkerUpdateNotify>
  <a class="service-worker-update-notify" href={{this.router.currentURL}}>
    A new version is available, click here to update.
  </a>
</ServiceWorkerUpdateNotify>

Using the service

The service allows you to react to an app update in a more programmatic manner, e.g.you could force reload the app. The service emits an update event once an updatehas been detected. Here is an example of an application route that reloads the appautomatically:

import Route from '@ember/routing/route';
import { inject as service } from '@ember/service';

export default class ApplicationRoute extends Route {
  @service
  serviceWorkerUpdateNotify;
  
  beforeModel() {
    this.serviceWorkerUpdateNotify.on('update', () => {
      window.location.reload();
    });
  }
}

Configuration

The poll interval can be configured in your config/environment.js with:

module.exports = function(environment) {
  let ENV = {
    'ember-service-worker-update-notify': {
      pollingInterval: 1200000 // Default is 20min
    }
  };

 return ENV;
};

Testing in Your App

Testing this in your app should mainly be concerned with presenceand and what it looks like.

During testing, the polling will be disabled,and the reveal of the "New version available" contentis controlled by a promise set on the window.In your tests, two helpers will aid you in assertingpresence and appearance: setupServiceWorkerUpdater,and hasServiceWorkerUpdate.

// ...
import {
  setupServiceWorkerUpdater,
  hasServiceWorkerUpdate
} from 'ember-service-worker-update-notify/test-support/updater';

module('Application | Index', function(hooks) {
  setupApplicationTest(hooks);
  setupServiceWorkerUpdater(hooks);

  test('the update is shown', async function(assert) {
    // assert that the content is not shown

    await serviceWorkerUpdate();

    // assert that the content is shown

  });
});
