Multiple databases in one NodeJS project with Mongoose?

Question

MongoDB

Is it possible to use multiple Mongo databases in one NodeJS application?
How to switch between them? How to organize the code?
Here is an example of what I have now:

mongoose.connect(process.env.DATABASE, { useMongoClient: true, autoReconnect: true, reconnectTries: 30, reconnectInterval: 1000 }, )
  .then(() => {
    console.log('Connected to Server successfully!')
  })
  .catch((err) => {
    console.log(` → ${err.message}`)
    return err
  })

So I connect to process.env.DATABASEand a collection is already created there according to my model.
But what if I want to use the same model BUT in relation to several databases?

Answer 1

Can. But it won't work.

Answer 2

I'm at a loss as to why the same model is in different databases (it's clear if there are different models in different databases), but you can
1. create multiple database connections using mongoosejs.com/docs/api.html#index_Mongoose-create ...
2. and then within this connection create a model mongoosejs.com/docs/api.html#connection_Connection...
