Password Value Object

This value object can be used to encapsulate the logic related with password creation and manipulation.

Usage​

Password VOs can only be created through the named constructors: fromRaw and fromHashed.

fromRaw(plain: string)​

Note: the method is asynchronous.

Allows us to create the VO from a plain password. For example, in the user creation.

const pass = await PasswordValueObject.fromRaw("12345");

fromHashed(hashed: string)​

Allows us to create the VO from a hashed password. For example, in the user db retrieving.

const pass = PasswordValueObject.fromHashed("$...");

Characteristics​

Password hashing - using bcrypt.​

By default, the passwords value objects only store the hashed representation of the password.

Password validation - using bcrypt.​

Allow us to compare the hash with a plain password.

Min and max length configuration.​

By default, the password should have a length between 5 and 20 (inclusive). It can be modified changing a static properties (options.min and options.max) in the class.

PasswordValueObject.options.min = 10;
PasswordValueObject.options.max = 50;
