Answer 1

If you would like to use findOrCreate, try the npm package mongoose-findorcreate, or supergoose

e.g. mongoose-findorcreate

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost');

var findOrCreate = require('mongoose-findorcreate')
var Schema = mongoose.Schema;
var UserSchema = new Schema({ facebookId: Number});
UserSchema.plugin(findOrCreate);
var User = mongoose.model('User', UserSchema);

passport.use(new FacebookStrategy({
        clientID: 'clientID',
        clientSecret: 'clientSecret',
        callbackURL: "/auth/facebook/callback"
    },
    function(accessToken, refreshToken, profile, cb) {
        User.findOrCreate({ facebookId: profile.id }, function (err, user) {
          console.log('A new uxer from "%s" was inserted', user.facebookId);
          return cb(err, user);
        });
    }
));
