Insert a Document
Note
If you specify a callback method, insertOne() 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 insert a document into a collection using the
collection.insertOne() method. To
insert a document, define an object that contains the fields and values that
you want to store. If the specified collection does not exist, the
insertOne() method creates the collection.
You can specify additional query options using the options parameter.
For more information on the method parameters, see the
insertOne() API documentation. You
can also pass a callback method as an optional third parameter.
For more information on this method, see the
insertOne() API documentation.
If the operation successfully inserts a document, it appends an
insertedId field to the object passed in the method call, and sets the
value of the field to the _id of the inserted document.
Example
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.
If you run the preceding example, you should see the following output:
A document was inserted with the _id: <your _id value>
