if you just want an array containing the collection names then you can use 

const collections = Object.keys(mongoose.connection.collections);

and you get a result like this 

[
  "identitycounters",
  "roles",
  "user"
]

depending on what's in your db.

Indeed, mongoose.connection.db.collectionNames was dropped in favor of mongoose.connection.db.listCollections.

const mongoose = require('mongoose');

const connection = mongoose.connect('mongodb://localhost:27017');

connection.on('open', function () {
    connection.db.listCollections().toArray(function (err, names) {
      if (err) {
        console.log(err);
      } else {
        console.log(names);
      }

      mongoose.connection.close();
    });
});
