Laravel Contacts

A Laravel package that provides a robust, event-sourced approach to managing multiple contact types (e.g., phone, email) for your Eloquent models. It offers features such as:

• Storing multiple contacts (phone/email, etc.) for a given model (e.g. User).
• Event-sourced creation, verification, and deletion of contacts.
• Configurable token-based verification mechanism (phone/email).
• Ability to designate primary contacts (only one primary at a time).
• Soft deletion with restore options.
• Support for UUIDs (configurable).
• Spatie Event Sourcing integration for auditing and replays.

Installation

1. Require this package in your Laravel application:

2. This package also relies on Spatie's Laravel Event Sourcing under the hood. If you have not already installed and configured Spatie's event sourcing package, you should do so.

Configuration

1. Publish Config:

   This will create a config/contacts.php file. Inside you will find the following key aspects:

   • model – The contact Eloquent model class (default: Kwidoo\Contacts\Models\Contact).
   • table – The database table for storing contacts (default: contacts).
   • uuid – Whether to use UUIDs as the primary key (boolean).
   • verifiers – A list of verifiers for different contact types (email, phone, etc.).
   • token – Configuration for token generation, including token length, TTL, and the token model/table.

2. Bind Twilio or Other Services: If you plan to use phone verification (PhoneVerifier), make sure you bind or configure any external SMS provider like Twilio. The example implementation references a Kwidoo\MultiAuth\Services\TwilioService. Adapt this service to your application’s needs.

3. Event Sourcing: This package automatically merges its required projector (\Kwidoo\Contacts\Projectors\ContactProjector::class) into your event-sourcing.projectors config. Make sure Spatie Event Sourcing is installed and configured appropriately.

Migrations

After installing, run:

This will publish and run the necessary migrations for storing contacts and tokens in your database.

Usage

Adding the HasContacts Trait

Any model (User, Company, etc.) that you wish to associate contacts with should implement Kwidoo\Contacts\Contracts\Contactable and use the Kwidoo\Contacts\Traits\HasContacts trait.

Example on a User model:

Important: The HasContacts trait adds a polymorphic relationship contacts() and also provides a getPrimaryContactAttribute accessor.

Creating Contacts

You can create a contact through the provided controller or directly through the ContactService.

Via Controller and Routes

The package registers RESTful routes for contacts. You can do a POST request to contacts (by default at /contacts) with the request body containing:

The validation ensures the type matches one of the configured verifiers (e.g., email, phone), and the value is unique for that model.

If successful, the route redirects to contacts.show (by default /contacts/{contact}).

Via ContactService

If you prefer direct usage in your code:

Listing Contacts

Using the built-in controller route:

• GET /contacts – Lists all contacts, paginated.
• If you wish to only get the contacts for a specific model (e.g., a single user), you need to ensure proper authorization or build your own route logic to filter the contacts.

Or directly from your model:

Verifying Contacts

Contacts can be verified via a token-based approach:

1. Initiate Verification:

   This calls VerificationController@sendVerification. It triggers a token generation and sends out the verification (via email or SMS, depending on the contact type).

2. Complete Verification:

   This calls VerificationController@verify. If the token is valid, the ContactVerified event is recorded, and the contact is marked as verified.

Deleting and Restoring Contacts

• Delete (Soft Delete):

  Calls the ContactController@destroy method, which uses ContactService::destroy($contact).

  Note: Attempting to delete a primary contact throws an exception.

• Restore:

  Calls ContactController@restore, which invokes ContactService::restore($uuid). This un-deletes the contact if it was soft-deleted.

Setting a Primary Contact

By default, the first contact you create becomes the primary contact. You can change the primary contact via:

This calls ContactController@markAsPrimary, leveraging the ContactAggregateRoot to update the primary contact.

Event Sourcing

This package uses Spatie's Event Sourcing to record:

• ContactCreated – Fired when a new contact is created.
• StartVerification – Fired when verification is initiated for a contact.
• ContactVerified – Fired when a contact is successfully verified.
• ContactDeleted – Fired when a contact is soft-deleted.
• PrimaryChanged – Fired when the primary contact is changed.

The ContactProjector listens for these events and updates the read models (the contacts table). If you need to replay or track changes, you can use event sourcing commands (e.g., php artisan event-sourcing:replay) to rebuild state.

Advantages

1. Event-Sourced: Full audit trail and ability to replay contact-related events.
2. Multiple Contact Types: Phone, email, or any custom type your application requires.
3. Token-Based Verification: Supports both email and phone verifications via token-based, OTP-like flows.
4. Soft Delete + Restore: Helps maintain history and preserves referential integrity.
5. Primary Contact Management: Ensures only one primary contact per model, with easy swaps.
6. Configurable UUIDs: Toggle between numeric IDs or UUIDs for your contacts.
7. Extensibility: Swappable verifiers, token generation, and external notification services (e.g., Twilio for SMS).
8. Polymorphic: Manage contacts for any Eloquent model (User, Company, etc.).

Additional Notes

• If you need to implement custom verifiers, simply create a class that implements the Kwidoo\Contacts\Contracts\Verifier interface and add it to the contacts.verifiers array in the configuration.
• For phone verification, ensure you have a proper SMS provider service (like Twilio) configured and replace the existing reference Kwidoo\MultiAuth\Services\TwilioService with your own implementation if needed.
• Make sure your policies (view, delete, update, etc.) align with your application’s authorization logic. The sample routes use typical Laravel policy checks, but you can modify or remove them as needed.
