This example shows you how to use to convert a password field into unreadable strings of characters.

  • An admin backend running on forest-express-sequelize

How it works

Directory: /models

This directory contains the users.js file where the model is declared.

/models/users.js
const bcrypt = require('bcrypt');

module.exports = (sequelize, DataTypes) => {
  const { Sequelize } = sequelize;

  const Users = sequelize.define('users', {
    email: {
      type: DataTypes.STRING,
    },
    password: {
      type: DataTypes.STRING,
      allowNull: true,
      // Storing passwords in plaintext in the database is terrible.
      // Hashing the value with an appropriate cryptographic hash function is better.
      set(value) {
        const hash = bcrypt.hashSync(value, 10);
        this.setDataValue('password', hash);
      },
    },
  }, {
    tableName: 'users',
    timestamps: false,
    schema: process.env.DATABASE_SCHEMA,
  });

npm package

In this example, we're using a for the password attribute of the users models.

The above example involving password handling, although much better than simply storing the password in plaintext, are far from perfect security. Handling passwords properly is hard, everything here is just for the sake of an example to show .
