How to switch database

In the mongo shell, I can do like this:

use admin
db.auth('user','pass')
use test
db.find()

This means I pass the authurized then I can do everything.

My problem is how can I do the same work in mongoose, how can I switch db in mongonse?

Because I must enter the ADMIN db to authurize, and then chang to other db to my own manipulation

other possible way is with query param in url

 mongodb://root:pass@localhost:27017/mydb?authSource=admin

look here -> Support AuthSource

Had problem to connect to a mongodb - coz the auth would bring me to a specific db like “admin” (standard). But how with mongoose? Only set the authSource inside of auth option…

var db = mongoose.createConnection(
  "localhost", 
  "myCostumDB", 
  "27010", 
  {
    user: "root",
    pass: "mypass",
    auth: {
      authSource: "admin" //<-- That is the Point.....
    }
  }
);
