Push Notifications

This starter template uses Firebase Cloud Messaging (FCM) to send push notifications to users.

FCM Token

The FCM tokens are stored in the fcmTokens subcollection of the users collection in Firebase Cloud Firestore:

users
└── <userId>
    └── fcmTokens
        └── <fcmToken>
            ├── token: string
            └── timestamp: string

It's recommended to remove stale FCM tokens from the database. Follow the instructions in the Firebase documentation to set up a Firebase Cloud Function that removes stale FCM tokens.

Send Push Notifications

To send push notifications, follow the instructions in the Push Notifications Guide for Capacitor.
