How to connect multiple mongo db in node.js?

Question

MongoDB

Tell me how can I connect two MongoDB databases in a node.js project?

A small explanation of what this is for:
Now there are two ready-made, working sites on node. The task is to make another one that would use a collection of users from the database of the first site and a collection with some data from the database of the second site. (When registering on a new site, the user must be saved in the database and be available for authorization on the first site)

Answer 1

You can use mongoose . The result will be something like this:

const mongoose = require('mongoose');

const firstConnection = mongoose.createConnection('опции для подключения')
const secondfirstConnection = mongoose.createConnection('опции для подключения')
