connect() (mongosh method)

Description

connect(url, user, password)

Creates a connection to a MongoDB instance and returns the reference to the database. However, in most cases, use the Mongo() object and its getDB() method instead.

Parameter	Type	Description
url	string	Specifies the connection string. You can specify either: <hostname>:<port>/<database> <hostname>/<database> <database>
user	string	Optional. Specifies an existing username with access privileges for this database. If user is specified, you must include the password parameter as well.
password	string	Optional unless the user parameter is specified. Specifies the password for the user.

Compatibility

This method is available in deployments hosted in the following environments:

• MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

• MongoDB Enterprise: The subscription-based, self-managed version of MongoDB
• MongoDB Community: The source-available, free-to-use, and self-managed version of MongoDB

Example

The following example instantiates a new connection to the MongoDB instance running on the localhost interface and returns a reference to myDatabase:

db = connect("localhost:27017/myDatabase")
