mongoose-unique-validator ReferenceError: User is not defined

I'm new to Node.js so I can't understand what I need to add, to make the default example from mongoose-unique-validator work. Here it is:

const mongoose = require('mongoose'),
  uniqueValidator = require('mongoose-unique-validator'),
  userSchema = mongoose.Schema({
    username: { type: String, required: true, unique: true },
    room: { type: String, required: true },
  });

userSchema.plugin(uniqueValidator);

const user = new User({ username: 'JohnSmith', room: 'asd');
user.save(function (err) {
    console.log(err);
});

The part with the user is not working, because of ReferenceError: User is not defined. As far as I understand, the user part is the part that the library user should define, but I don't know what should be in there to make it work.

TL; DR:

I just want to make an example work. Thanks.

Update:

Ok, so I've added this line of code:

const User = mongoose.model('Model', userSchema);

and it does not trows an error anymore. But it does not notify that username is not unique. It does not work yet. I want to check a valid username for the room. And that's all.

you didn't define your model collection ("USER") try this:

const mongoose = require('mongoose'),
  uniqueValidator = require('mongoose-unique-validator'),
userSchema = mongoose.Schema({
    username: { type: String, required: true, unique: true },
    room: { type: String, required: true },
  });

userSchema.plugin(uniqueValidator);


module.exports.User = mongoose.model('User', UserSchema);

then :

const user = new User({ username: 'JohnSmith', room: 'asd');
user.save(function (err) {
    console.log(err);
})
