If I use Mongoose in node.js I need to do:
var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/myDB'); But what if I just installed mongodb and I don't have any DB at the moment? How can I create a new DB using mongoose in node.js before doing mongoose.connect('mongodb://localhost/myDB')? Or if there is no such myDB then it will create a new one? or will throw an error that there is no such a DB?

Yes, you can specify the database name in your connection string. and that will create all your records under the name 'dbname2'.
Creating a MongoDB Database with the CLIMongoDB only creates the database when you first store data in that database. This data could be a collection or even a document. To add a document to your database, use the db.
In Studio 3T:In the Connection Tree, right-click on the target server. Choose Add Database. Name your database – and note the info message. Click on OK.
It should not throw any error. The moment you insert a document in any new collection of that DB, the collection and db will be created
