Delete documents and fields

The following examples demonstrate how to delete documents, fields, and collections.

Delete documents

To delete a document, use the following language-specific delete() methods:

Web version 9

Use the deleteDoc() method:

import { doc, deleteDoc } from "firebase/firestore";

await deleteDoc(doc(db, "cities", "DC"));
delete_document.js

Web version 8

Use the delete() method:

db.collection("cities").doc("DC").delete().then(() => {
    console.log("Document successfully deleted!");
}).catch((error) => {
    console.error("Error removing document: ", error);
});
test.firestore.js
Swift

Use the delete() method:

do {
  try await db.collection("cities").document("DC").delete()
  print("Document successfully removed!")
} catch {
  print("Error removing document: \(error)")
}
ViewController.swift
Objective-C

Use the deleteDocumentWithCompletion: method:

Note: This product is not available on watchOS and App Clip targets. 
[[[self.db collectionWithPath:@"cities"] documentWithPath:@"DC"]
    deleteDocumentWithCompletion:^(NSError * _Nullable error) {
      if (error != nil) {
        NSLog(@"Error removing document: %@", error);
      } else {
        NSLog(@"Document successfully removed!");
      }
}];

Use the delete() method:

C++

Use the Delete() method:

db->Collection("cities").Document("DC").Delete().OnCompletion(
    [](const Future<void>& future) {
      if (future.error() == Error::kErrorOk) {
        std::cout << "DocumentSnapshot successfully deleted!" << std::endl;
      } else {
        std::cout << "Error deleting document: " << future.error_message()
                  << std::endl;
      }
    });

)

func deleteDoc(ctx context.Context, client *firestore.Client) error {
	_, err := client.Collection("cities").Doc("DC").Delete(ctx)
	if err != nil {
		// Handle any errors in an appropriate way, such as returning them.
		log.Printf("An error has occurred: %s", err)
	}

	return err
}
