how to encrypt passwords with beforeBulkCreate hook in sequelize - node.js

Question

I´m trying to encrypt password before bulk create with sequelize.
const bcrypt = require('bcryptjs');
module.exports = (sequelize, DataTypes) => {
const User = sequelize.define('users', {
username: {
type: DataTypes.STRING,
allowNull: false,
required: true
},
password: {
type: DataTypes.STRING,
allowNull: false,
required: true
},
},
{
freezeTableName: true,
hooks: {
beforeBulkCreate: function(records) {
records.forEach((user, index) => {
return bcrypt.hash(user.password, 10)
.then(hash => {
user.password = hash;
console.log('password hash:', user.password);
})
.catch(err => {
throw new Error();
});
})
},
beforeCreate: (user) => {
return bcrypt.hash(user.password, 10)
.then(hash => {
user.password = hash;
})
.catch(err => {
throw new Error();
});
}
}
});
User.prototype.validPassword = (password) => {
return bcrypt.compareSync(password, this.password);
};
return User;
}
hooks is called but the password that´s store in the database is the plain one not the new one
const userData = [
{ username: 'John', password: '123' },
{ username: 'Mary', password: '321' },
];
User.bulkCreate(userData, { returning: true })
.then((result) => {
console.log('User data success');
})
.catch((error) => {
console.log(error);
});
I also tried passing the { individualHooks: true } option but doing this records are not being inserted at all.

I came here in search of an answer to this ~ 3 years old question. Chances are that >= 3 years later someone else will come looking for the same.
Here, I solved mine using bcrypt.hashSync()
I know they recommend using the asynchronous bcrypt.hash() solution but sometimes most optimal isn't always the solution.
You can learn more here bcrypt npm docs
hooks: {
beforeBulkCreate: (users) => {
users.forEach((user) => {
// to see the properties added by sequelize
console.table(user);
// now modify the "dataValues" property
user.dataValues.password = bcrypt.hashSync(user.password, 10);
});
},
// other hooks here
},
