How to encrypt password in Sequelize

users.js

import Sequelize from 'sequelize'
import bcrypt from 'bcrypt-nodejs'
import connection from '../config/db'

require('sequelize-isunique-validator')(Sequelize)

let User = connection.define('user', {
  firstName: {
    type: Sequelize.STRING(50),
    allowNull: false,
    validate: {
      len: {
        args: [0, 50],
        msg: 'El nombre tiene demasiados carácteres'
      }
    }
  },
  lastName: {
    type: Sequelize.STRING(100),
    allowNull: false,
    validate: {
      len: {
        args: [0, 100],
        msg: 'Los apellidos tienen demasiados carácteres'
      }
    }
  },
  email: {
    type: Sequelize.STRING(100),
    allowNull: false,
    unique: true,
    validate: {
      isEmail: {
        msg: 'No es una dirección de correo electrónico.'
      },
      isUnique: connection.validateIsUnique(
        'email',
        'Esta dirección de correo electrónico ya existe.'
      )
    }
  },
  password: {
    type: Sequelize.STRING,
    allowNull: false
  }
}, {
  instanceMethods: {
    generateHash: function (password) {
      return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null)
    },
    validPassword: function (password) {
      return bcrypt.compareSync(password, this.password)
    }
  }
})

User.sync()

export default User

Node is single threaded + Bcrypt is slow => This will make the server unresponsive for the duration of the synchronous functions. Do not do this in production.

Go async instead.

  User.beforeCreate(function(user, options) {
    return cryptPassword(user.password)
      .then(success => {
        user.password = success;
      })
      .catch(err => {
        if (err) console.log(err);
      });
  });

function cryptPassword(password) {
  console.log("cryptPassword" + password);
  return new Promise(function(resolve, reject) {
    bcrypt.genSalt(10, function(err, salt) {
      // Encrypt password using bycrpt module
      if (err) return reject(err);

      bcrypt.hash(password, salt, null, function(err, hash) {
        if (err) return reject(err);
        return resolve(hash);
      });
    });
  });

This works with beforeCreate but not for beforeBulkUpdate. Not sure why.

@hansaliyad1, because You need to specify the hook correctly and map all the array of the users.
In the map function, You will be able to crypt a password.

@AdityaAnand1 can u provide the full example please?
