Mongoose password hashing

Question

I am looking for a good way to save an Account to MongoDB using mongoose.

My problem is: The password is hashed asynchronously. A setter wont work here because it on

The Mongoose official solution requires the model to be saved before using the verifyPass method, which can cause confusion. Would the following work for you? (I am using scrypt instead of bcrypt).

userSchema.virtual('pass').set(function(password) {
    this._password = password;
});

userSchema.pre('save', function(next) {
    if (this._password === undefined)
        return next();

    var pwBuf = new Buffer(this._password);
    var params = scrypt.params(0.1);
    scrypt.hash(pwBuf, params, function(err, hash) {
        if (err)
            return next(err);
        this.pwHash = hash;
        next();
    });
});

userSchema.methods.verifyPass = function(password, cb) {
    if (this._password !== undefined)
        return cb(null, this._password === password);

    var pwBuf = new Buffer(password);
    scrypt.verify(this.pwHash, pwBuf, function(err, isMatch) {
        return cb(null, !err && isMatch);
    });
};
