Explanation of exporting createConnection and models is confusing in docs and maybe wrong. about mongoose HOT 4 OPEN

I think the names fast.js and slow.js is not the most appropiate names, but its basically called slow.js because we are initializing one extra model. I don't think there's anything more deeper than that to it.

It says to export the connection

const conn = mongoose.createConnection(process.env.MONGODB_URI);
conn.model('User', require('../schemas/user'));

module.exports = conn;
But this gives a "Not a function" error when trying to use it in another file.

Can you show the code how you are using it in the other file?

Btw, your second approach is good if you are only planning to export one model. Otherwise you can also export multiple models too by doing exports.User = User;

from mongoose.
