Delete a Document

Info With Circle IconCreated with Sketch.Note

If you specify a callback method, deleteOne() returns nothing. If you 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.

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.

The following snippet deletes a single document from the movies collection. It uses a query document that configures the query to match only movies with a title of type string.

This example connects to an instance of MongoDB using a connection string. To learn more about connecting to your MongoDB instance, see the connection guide.

const { MongoClient } = require("mongodb");
// Replace the uri string with your MongoDB deployment's connection string.
const uri =
const client = new MongoClient(uri);
async function run() {
try {
await client.connect();
const database = client.db("sample_mflix");
const movies = database.collection("movies");
// Query for a movie that has a title of type string
const query = { title: { $type: "string" } };
const result = await movies.deleteOne(query);
if (result.deletedCount === 1) {
console.dir("Successfully deleted one document.");
} else {
console.log("No documents matched the query. Deleted 0 documents.");
} finally {
await client.close();
