How to Get the Database URL in MongoDB

Below are the approaches that can help us to Get the Database URL in MongoDB are as follows:

1. Connection String from MongoDB Atlas
2. Connection String from Local MongoDB Instance
3. Connection String from Configuration File

Structure of MongoDB Connection URI:

A typical MongoDB connection URI follows the format

mongodb://username:password@host1:port1,host2:port2/database?option1=value1&option2=value2

Explanation:

• mongodb://: The protocol prefix indicating that the URI is for a MongoDB connection.
• username:password: Optional authentication credentials. If authentication is not required, this part can be omitted.
• @host1:port1,host2:port2: Comma-separated list of MongoDB hosts and ports. MongoDB supports connecting to replica sets or sharded clusters, so multiple hosts and ports can be specified.
• /database: The name of the MongoDB database to connect to.
• ?option1=value1&option2=value2: Optional connection options specified as query parameters.

1. Connection String from MongoDB Atlas

If we are using MongoDB Atlas, a cloud-hosted MongoDB service, the connection string can be obtained from the Atlas dashboard.

• Log in to your MongoDB Atlas account.
• Navigate to the “Clusters” section and select your cluster.
• Click on the “Connect” button.
• Choose “Connect Your Application”.
• Copy the connection string provided.

Example Connection String from MongoDB Atlas:

mongodb+srv://

username:password@cluster0.abcde.mongodb.net/mydatabase?retryWrites=true&w=majority

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.
