48-Nodejs Course 2023: Database Models: Custom Data Casting: Encrypted Password

Custom Casts

Now let's talk about custom casts, what if we want to cast a value to a custom type, for example, we want to cast the password value.

Let's make a folder called casts in the src/core/database/casts folder and create cast-password.ts file.

We need to generate a make a password generated and to be solid, we will use Password Hash Generator And Verifier to achieve this easily.

Let's install it

yarn add @mongez/password

Now let's create the cast-password.ts file

// src/core/database/casts/cast-password.ts import { hash } from '@mongez/password'; /** * Cast password */ export default function castPassword( columnName: string, value: any ) { return hash(value, 15); // second argument is the salt }

Now let's update the User model to use this cast

// src/app/users/models/user.ts import { Model } from "core/database"; import castPassword from "core/database/casts/cast-password"; import { Casts, Document } from "core/database/model/types"; export default class User extends Model { /** * Collection name */ public static collectionName = "users"; /** * {@inheritDoc} */ public defaultValue: Document = { isActive: true, isEmailVerified: false, isPhoneVerified: false, }; protected casts: Casts = { isActive: "boolean", isPhoneVerified: "boolean", joinDate: "date", password: castPassword, }; }

Now let's try to create a new user

// src/app/users/routes.ts import User from './models/user'; const user = new User({ name: 'Hassan', password: '123456', }); await user.save(); consol.log(user.data); // { name: 'Hassan', password: '$2b$23$...' }
