QueryDocumentSnapshot class
Stay organized with collections
Save and categorize content based on your preferences.
A QueryDocumentSnapshot
contains data read from a document in your Firestore database as part of a query. The document is guaranteed to exist and its data can be extracted with .data()
or .get(<field>)
to get a specific field.
A QueryDocumentSnapshot
offers the same API surface as a DocumentSnapshot
. Since query results contain only existing documents, the exists
property will always be true and data()
will never return 'undefined'.
Signature:
export declare class QueryDocumentSnapshot<AppModelType = DocumentData , DbModelType extends DocumentData = DocumentData> extends DocumentSnapshot<AppModelType , DbModelType>
Extends: DocumentSnapshot <AppModelType, DbModelType>
