Mongo.getDBs()

Description

Mongo.getDBs()

Returns information about all available databases. Mongo.getDBs() uses the listDatabases command.

The Mongo.getDBs() method doesn't take any parameters.

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

To list the available databases and metadata for the local MongoDB instance:

db.getMongo().getDBs()

The db.getMongo() method returns the connection to the current MongoDB instance. The Mongo.getDBs() output resembles:

{
 databases: [
   { name: 'admin', sizeOnDisk: Long("225280"), empty: false },
   { name: 'config', sizeOnDisk: Long("212992"), empty: false },
   { name: 'local', sizeOnDisk: Long("2400256"), empty: false },
   { name: 'test', sizeOnDisk: Long("303104"), empty: false }
 ],
 totalSize: Long("3141632"),
 totalSizeMb: Long("2"),
 ok: 1,
 '$clusterTime': {
   clusterTime: Timestamp({ t: 1640186473, i: 1 }),
   signature: {
     hash: Binary(Buffer.from("0000000000000000000000000000000000000000", "hex"), 0),
     keyId: Long("0")
   }
 },
 operationTime: Timestamp({ t: 1640186473, i: 1 })
 }

The databases are listed in the highlighted lines.
