Connection String from Local MongoDB Instance

If we have a local MongoDB instance running on your machine, you can obtain the connection string by following these steps:

1. Open a terminal or command prompt.
2. Start the MongoDB server if it’s not already running.
3. Run the `mongo` command to open the MongoDB shell.
4. Run the `db` command to switch to a specific database (optional).
5. Run the `db.getMongo()` command to get the connection string.

Output:

{
  "ismaster" : true,
  "maxBsonObjectSize" : 16777216,
  "maxMessageSizeBytes" : 48000000,
  "maxWriteBatchSize" : 100000,
  "localTime" : ISODate("2022-04-06T08:53:47.533Z"),
  "logicalSessionTimeoutMinutes" : 30,
  "connectionId" : 17,
  "minWireVersion" : 0,
  "maxWireVersion" : 14,
  "readOnly" : false,
  "ok" : 1
}

The connection string can be extracted from the me field.

In MongoDB, the database URL also known as the connection string or connection URI (Uniform Resource Identifier) is a important piece of information required to establish a connection to a MongoDB database. It contains all the necessary details for connecting to the MongoDB server, including the hostname, port number, database name, and authentication credentials.

In this article, we’ll explore how to obtain the database URL in MongoDB by covering various scenarios and providing examples with outputs to understand the concept effectively.
