Description

Mongo.getDBs()

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

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

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.
