Model

To represent an User Model

export class UserModel {

    constructor(
        public readonly id: UuidVO,
        public username: UsernameVO,

        public password: PasswordVO,
    ) { }
    
}

Value Object

export class UuidVO extends ValueObject<string> {


    public assertIsValid(value: string): void {
        if (!validate(value)) {
            throw new VOFormatException(UuidVO.name, value)
        }
    }

    public equals(valueObject: UuidVO) {
        return this.value === valueObject.value
    }
}
