Get Firestore document as plain Javascript object?

Question

I'm currently manually itearting over document fields in firestore and putting them into an object which I stringify to JSON.

Is there a way to automate the process? Something like:

var userEnrollments = ToJson(await admin.firestore().collection(USERS + "/" + x.uid + "/" + ENROLMENT));

Answer 1

DocumentSnapshot has a method data() that returns the entire contents (without subcollections) of the document as a plain JavaScript object.

admin.firestore().doc('path/to/doc').get().then(snapshot => {
    const data = snapshot.data()  // a plain JS object 
})
