How to create a new db in mongoose?

Question

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?

Solution

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

This answer appears to be specific to express and also does not answer the question very well.
