Create Documents

Insert single record

To create a todo application, we insert a task into the MongoDB collection. We can assign any name to the collection, but it should be relative to the data stored in that collection. Here, we’ll choose tasks.

We can use the below command to choose a database.

use todo;

Below is the syntax to insert a single document.

db.<collection name>.insertOne(Document, Options);

The Document argument is an object that specifies properties in the <key>:<value> pattern.

Below is the property of the Options argument of the insertOne command.
