Type casting is not working here:

docSnapshots<Post>(
  doc(this.afs, `posts/${id}`)
);
Enter fullscreen mode Exit fullscreen mode 
Argument of type 'DocumentReference<DocumentData>' is not assignable to parameter of type 'DocumentReference<Post>'.
  The types returned by 'converter.fromFirestore(...)' are incompatible between these types.
    Type 'DocumentData' is not assignable to type 'Post'.ts(2345)
Enter fullscreen mode Exit fullscreen mode

Yes, Angular Firebase is definitely not perfected code with Firebase 9. You can get around that with:

docSnapshots<Post>(
  doc(this.afs, `posts/${id}`) as DocumentReference<Post>
);
Enter fullscreen mode Exit fullscreen mode

Thank you. This has been very useful today. I'm starting a new project and want to use the new APIs but the lack of documentation is infuriating.

Read my updated article on this - this article is out-of-date - code.build/p/angular-todo-app-with... - make sure you're using importProvidersFrom()

HI: This code doesn't work with 7.4.1 and angular 14.
this.user$ = user(auth).pipe(
switchMap((user: User | null) =>
user
? docData(doc(this.afs, 'users', user.uid))
as Observable
: of(null)
)
);

Thanks so much for this! You wrote "I may update this with more items..." and I cant' wait. We need articles like this, bc the official @angular/angularfire documentation is awful.

Is there something you specifically need? If so I can add it!

Nothing specific, just more of that juicy stuff - the more the better.

Great reference, thank you. Turns out when you step away from AngularFire for a year+ several things change lol.

Yes, just look at the where examples above. Pagination will use limit() and orderBy() as usual, just import them.

When adding a new document to firestore, how do we tell it to auto generate id? If I don't put id in doc() it gives me an error.
