I'm using bcrypt-nodejs to hashify passwords within a pre save function. I can't figure out why I continue to receive the error '[TypeError: undefined is not a function]' inside the callback function of bcrypt.hash.
var mongoose = require('mongoose'),
validate = require('mongoose-validate'),
bcrypt = require('bcrypt-nodejs'),
SALT_WORK_FACTOR = 10,
REQUIRED_PASSWORD_LENGTH = 8;
function validateStringLength (value) {
return value && value.length >= REQUIRED_PASSWORD_LENGTH;
}
var schema = mongoose.Schema({
email: {type: String,
required: true,
unique: true,
validate: [validate.email, 'is not a valid email address']
},
passHash: {type: String,
required: true,
validate: [validateStringLength, 'The password must be of min ' + REQUIRED_PASSWORD_LENGTH + ' characters length.']}
});
schema.pre('save', function (next) {
var self = this;
if (!self.isModified('passHash')) return next();
bcrypt.hash(self.passHash, SALT_WORK_FACTOR, null, function encryptedPassword (err, hash) {
if(err) console.log(err);
self.passHash = hash;
next();
});
});
schema.set('autoIndex', App.env !== 'production');
var Model = mongoose.model('User', schema);
module.exports = Model;
I checked the parameters passed and they are correct. Also the hash returned is null.
Does anyone had a similar experience? I'm using bcrypt-nodejs because bcrypt gives me error during the installation with npm.
Reproducable with this:
var bcrypt = require('bcrypt-nodejs')
bcrypt.hash('foo', 10, null, function(err) {
if (err) throw err;
});
The issue is that the salt needs to be a string (internally, bcrypt-nodejs
is using salt.charAt()
, and charAt()
is undefined for numbers).
You probably want this:
bcrypt.hash(self.passHash, bcrypt.genSaltSync(SALT_WORK_FACTOR), ...);
(or the async version, bcrypt.genSalt()
)
