Is snapshot.ref equivalent to firestore.collection('snapshotCollection').doc(snapshot.id)?

Question

If I want to get a firebase document reference to use it in a filter for another query:

.where('project', '==', projectDocRef)

to get the project reference is equivalent to do:

projectDocRef = snapshot.ref;

and

proyectDocRef = firestore.collection('projectcolection').doc(snapshot.id);

?

Does any of the alternatives have any advantages?

Answer 1

No, 1st method can be used only when you've fetched the document already and have its DocumentSnapshot. Using ref would convenient here.

When you don't have a DocumentSnapshot, then you would have to use.doc() to get a DocumentReference.

You can remove.collection() just yo reduce some code like:

proyectDocRef = firestore.doc('projectcolection/docID')
