When using Angularfire, the function to switch the type from snapshotChanges will consistently return the value as "value"

At this moment, when I use the Angularfire extension to call the following code:

this.db.doc(path).snapshotChanges();

Angularfire always retrieves a DocumentSnapshot with a type that is consistently "value", regardless of the actual change type. Is there a way to work around this or to actually get the change type in the latest version of Angularfire when fetching a document?

I also left a comment on a bug that was reported around a year ago, but there is one particular comment from a member that I don't fully understand. You can view it by following this link:

Thank you in advance.

Answer №1

Perhaps this information could be of assistance to you

this.database
  .collection('collectionName')
  .snapshotChanges()
  .pipe(
    map(changes => changes.map((action: DocumentChangeAction<any>) => {
      return {
        ...action.payload.doc.data(),
        id: action.payload.doc.id,
        type: action.type
      };
    }))
  );

Answer №2

The official documentation states that the snapshotChanges() method can be utilized along with change type.

this.db.doc(path).snapshotChanges()
  .pipe(map(schedules => console.log(schedules.type)));
