title: Push Notifications, Multiple Service Workers? Angular Ionic 5 PWA for Web/Android/IOS and Firebase
body: <p>I'm having trouble with my Ionic/Angular Capacitor PWA. I need to set up  PUSH NOTIFICATIONS for Web, Android and IOS but right now just focusing on Web.</p>
  
  <p>I have Angular app set up to ask the user permission for notifications. I store a token in firestore using the firebase uid they logged in with when they respond 'YES'. I have firebase functions that are supposed to fire onCreate of a particular document type when it is created in the firestore db.</p>
  
  <p>My problem is the next step. Everywhere I look I am supposed to set up a service worker to handle the notifications. But I already HAVE one (PWA) and I don't know how to set up another service worker that wont mess up the PWA sw. </p>
  
  <p>Somehow I need to make this work cross-platform. I will need to make it work for Web right now but later for android/ionic too.</p>
  
  <p>Can I use multiple service workers without causing problems? How?
  How will it change when I do Android/IOS implementation?
  Is there a resource you could point me to? </p>
  
  <p>Thanks in advance</p>
