This new tutorial teaches CREATE, UPDATE, DELETE, and OBSERVABLE operations using AngularFire. A few issues:

Section 8. I don't understand how to use the Firestore Data Converter interface so I tell readers not to make types or interfaces for Firestore collections, but instead to set the type to . Could someone who knows how to use the Firestore Data Converter interface rewrite Section 8.1 to teach best practices (i.e., not use any)?

Section 17. I tell readers that “best practices” is to update properties of documents but not to update documents. Instead, delete the document and make a new document.

Section 18. I wrote that AngularFire doesn’t have a READ operation. Firebase has get() but AngularFire doesn’t support get(). Is there no use case when we need get()?

Section 19. I wrote that Firebase and AngularFire support Observables for binding data from Firebase to Angular. In other words, AngularFire isn’t CRUD, it’s C*UDO.

Section 19. I wrote that there’s no Observable in Firebase to watch for changes in Angular. I.e., when your data changes in Angular you have to send an update() query to Firebase.

I tried to make a StackBlitz but I didn't see how to connect to Firebase without the environment.ts credentials.

If this tutorial is accepted I’ll write a tutorial for Auth OAuth2 providers and another tutorial for Auth email&password.
