Delete a Document
Note
If you specify a callback method, deleteOne() returns nothing. If you
do not specify one, this method returns a Promise that resolves to the
result object when it completes. See our guide on Promises and
Callbacks for more information, or the
API documentation for
information on the result object.
You can delete a single document in a collection with
collection.deleteOne().
The deleteOne() method uses a query document that you provide
to match the subset of the documents in the collection that match
the query. If you do not provide a query document (or if you provide an
empty document), MongoDB matches all documents in the collection and
deletes the first match.
You can specify additional query options using the
options object passed as the second parameter of the
deleteOne method. You can also pass a
callback method
as an optional third parameter. For more information on this method,
see the
deleteOne() API documentation.
Note
If your application requires the deleted document after deletion,
consider using the
collection.findOneAndDelete().
method, which has a similar interface to deleteOne() but also
returns the deleted document.
Example
The following snippet deletes a single document from the movies
collection. It uses a query document that configures the query
to match movies with a title value of "Annie Hall".
Note
You can use this example to connect to an instance of MongoDB and interact with a database that contains sample data. To learn more about connecting to your MongoDB instance and loading a sample dataset, see the Usage Examples guide.
Note
Identical Code Snippets
The JavaScript and TypeScript code snippets above are identical. There are no TypeScript specific features of the driver relevant to this use case.
If you run the preceding example, you should see the following output:
Successfully deleted one document.
On subsequent runs of the preceding example, as you already deleted the document that matched your query, you should see the following output:
No documents matched the query. Deleted 0 documents.
