Authentication

Dynamic authentication api. Extremely configurable authentication system with a default sweet spot. By itself the authentication system is agnostic to the transport used to authenticate users, you need to mount this in express routes for example, and then depending the results of the dynamics respond to your users with the adequate messages and data.

Install

npm install @universal-packages/authentication

Authentication

The Authentication class is a descendant of DynamicApi class, it is the entry interface to load and perform all our authentication related dynamics.

import { Authentication } from '@universal-packages/authentication'

const authentication = new Authentication({ dynamicsLocation: './src', secret: 'my secret' })

await authentication.loadDynamics()

const result = await authentication.performDynamic('log-in', { credential: 'username', password: '12345678' })

console.log(result)

// > { status: 'success', authenticatable: { id: 69, username: 'username', createdAt: [Date] } }

By default authentication comes packed with a whole default auth system, but we can override all or part of the system by creating non default dynamics in your dynamics location with the extension prefix auth-dynamic, ex: LogIn.auth-dynamic.js and export ad default dynamic class there. More about all the dynamics that can be override below.

Options

Authentication take options similar to DynamicApi options:

• debug Boolean If true the instance of this authentication dynamic api will keep track of what is being performed into a log.

• dynamicsLocation Required String Where to look up for dynamics to load withe to override default ones or new ones.

• secret Required String Secret used for cryptography to generate tokens and verifying them for this authentication instance in particular.

• email AuthenticationCredentialOptions Options related to email authentication

  • confirmationGracePeriod String ex: 2 days If provided an authenticatable will need to confirm its email before this time or log in will not work until confirmed.
  • enableConfirmation Boolean If true all confirmation behavior will take place, like verifying grace period or if an authenticatable needs to be confirmed to continue log-in.
  • enableCorroboration Boolean If true before signing up the email should be corroborated.
  • enableMultiFactor Boolean If true, and if the authenticatable has it configured,to complete a log in with email, the authenticatable needs to verify multi-factor.
  • enablePasswordCheck Boolean default: true If true a password will be required at login if the authenticatable has it set.
  • enableSignUP Boolean default: true If true an authenticatable can sign up using tis kind of credential.
  • enableSignUpInvitations Boolean If true an authenticatable can sign up using an invitation as well as sending them.
  • enforceMultiFactor Boolean If true, to complete a log in with email, the authenticatable always needs to verify multi-factor.
  • enforceConfirmation Boolean If true, an authenticatable always need to be confirmed to be able to log in.
  • enforcePasswordCheck Boolean default: true If true a password will be required at login always.
  • enforceSignUpInvitations Boolean If true an authenticatable can only sign up if an invitation was issued for it.
  • sendMultiFactorInPlace Boolean If true, the send-multi-factor dynamic will be performed after successfully logging in, if false, it will be need to be sent later, useful to let the user select a channel to end the multi-factor.

• enableLocking Boolean if true, an authenticatable can be locked after several failed log in attempts.

• enableLogInCount Boolean if true, every time an authenticatable login successfully the count will be up and saved.

• maxAttemptsUntilLock Number default: 5 After how many failed log in attempts an authenticatable should be locked.

• multiFactorActivityLimit String default: 5 minutes After a successful login first step, for how much time should we consider the multi factor as active?, if the time has passed the user should do the first step again.

• phone AuthenticationCredentialOptions Options related to phone authentication

  • confirmationGracePeriod String ex: 2 days If provided an authenticatable will need to confirm its phone before this time or log in will not work until confirmed (for phone usually we corroborate at sign up so this is not a dynamic commonly used).
  • enableConfirmation Boolean If true all confirmation behavior will take place, like verifying grace period or if an authenticatable needs to be confirmed to continue log-in.
  • enableMultiFactor Boolean default: true If true, and if the authenticatable has it configured,to complete a log in with phone, the authenticatable needs to verify multi-factor.
  • enablePasswordCheck Boolean If true a password will be required at login if the authenticatable has it set.
  • enableCorroboration Boolean default: true If true before signing up the phone should be corroborated.
  • enableSignUP Boolean default: true If true an authenticatable can sign up using tis kind of credential.
  • enableSignUpInvitations Boolean If true an authenticatable can sign up using an invitation as well as sending them.
  • enforceMultiFactor Boolean default: true If true, to complete a log in with phone, the authenticatable always needs to verify multi-factor.
  • enforceConfirmation Boolean If true, an authenticatable always need to be confirmed to be able to log in.
  • enforcePasswordCheck Boolean If true a password will be required at login always.
  • enforceSignUpInvitations Boolean If true an authenticatable can only sign up if an invitation was issued for it.
  • sendMultiFactorInPlace Boolean If true, the send-multi-factor dynamic will be performed after successfully logging in, if false, it will be need to be sent later, useful to let the user select a channel to end the multi-factor.

• providerKeys { provider: Object } If a provider dynamic needs a set of keys here they should be placed to be read inside the dynamic.

• unlockAfter String ex: 1 hour When an authenticatable is locked it automatically unlocks after this time has passed.

• validations AttributesValidationOptions Options related to how every assignable attribute should be validated at sign up/reset password dynamics.

    • size { min?: number; max?: number } If provided teh value length should be between min and/or max.
    • validator Regex A validator function for a custom coded validation.

Authenticatable

Internally this auth system will handle an abstract Authenticatable class, we need to provided it in order for the whole thing to work.

import User from './User'

authentication.setAuthenticatable(User)

import { Encrypt } from '@universal-packages/authentication'

export default class User {
  id

  profilePictureUrl

  email
  emailConfirmedAt
  unconfirmedEmail

  phone
  phoneConfirmedAt
  unconfirmedPhone

  username

  failedLogInAttempts
  lockedAt

  logInCount

  multiFactorEnabled
  multiFactorActiveAt

  @Encrypt()
  password
  encryptedPassword

  firstName
  lastName
  name

  inviterId

  createdAt
  updatedAt

  save() {}

  static async existsWithCredential(credentialKind, credential) {}
  static async existsWithUsername(username) {}
  static async findById(id) {}
  static async findByCredential(credential) {}
  static async findByProviderId(provider, id) {}
}

Decorators

Encrypt([propertyToEncrypt: string])

Use this decorator to automatically encrypt attributes in a class. For example for the password attribute, when decorated, every time is set, the encryptedPassword attribute is going to set with a hashed and salted string based on the password. It sets depending on the base attribute name encrypted<Attribute>.

import { Encrypt } from '@universal-packages/authentication'

export default class User {
  @Encrypt()
  secret
  encryptedSecret
}

const user = new User()

user.secret = 'my password'

console.log(user.secret, user.encryptedSecret)

// > undefined C49HSl4okw8yoCKfoNRnsqD4T0T6SJZkdpTgU1o478Mk4GT995KV5HUKzvsnN1fShOo9sdDQq3Rjiz+Brj9bCIeJfWrt7tMl936wWyBARkPCdDlj9OfLNNDnhGo7dkmbU8YBfpgcmoMUmCuIftupOik+Nk/Eu83J4epW5y2w0fM=

You can also specify the attribute name to store the hashed password.

import { Encrypt } from '@universal-packages/authentication'

export default class User {
  @Encrypt('hashedSecret')
  secret
  hashedSecret
}
