Installation

1. Install the package via composer

composer require benbjurstrom/plink

2. Add the package's interface and trait to your Authenticatable model

// app/Models/User.php
namespace App\Models;

//...
use BenBjurstrom\Plink\Models\Concerns\HasPlinks;
use BenBjurstrom\Plink\Models\Concerns\Plinkable;

class User extends Authenticatable implements Plinkable
{
    use HasFactory, Notifiable, HasPlinks;
    
    // ...
}

3. Publish and run the migrations

php artisan vendor:publish --tag="plink-migrations"
php artisan migrate

4. Add the package provided routes

// routes/web.php
Route::plinkRoutes();

5. (Optional) Publish the views for custom styling

php artisan vendor:publish --tag="plink-views"

This package publishes the following views:

resources/
└── views/
    └── vendor/
        └── plink/
            ├── error.blade.php
            ├── components/
                └── template.blade.php
            └── mail/
                ├── notification.blade.php
                └── plink.blade.php

6. (Optional) Publish the config file

php artisan vendor:publish --tag="plink-config"

This is the contents of the published config file:

<?php

return [
    /*
    |--------------------------------------------------------------------------
    | Link Expiration and Throttling
    |--------------------------------------------------------------------------
    |
    | These settings control the security aspects of the generated links,
    | including their expiration time and the throttling mechanism to prevent
    | abuse.
    |
    */

    'expiration' => 5, // Minutes

    'limits' => [
        ['limit' => 1, 'minutes' => 1],
        ['limit' => 3, 'minutes' => 5],
        ['limit' => 5, 'minutes' => 30],
    ],

    /*
    |--------------------------------------------------------------------------
    | Model Configuration
    |--------------------------------------------------------------------------
    |
    | This setting determines the model used by Plink to store and retrieve
    | one-time passwords. By default, it uses the 'App\Models\User' model.
    |
    */

    'models' => [
        'authenticatable' => env('AUTH_MODEL', App\Models\User::class),
    ],

    /*
    |--------------------------------------------------------------------------
    | Mailable Configuration
    |--------------------------------------------------------------------------
    |
    | This setting determines the Mailable class used by Plink to send emails.
    | Change this to your own Mailable class if you want to customize the email
    | sending behavior.
    |
    */

    'mailable' => BenBjurstrom\Plink\Mail\PlinkMail::class,

    /*
    |--------------------------------------------------------------------------
    | Template Configuration
    |--------------------------------------------------------------------------
    |
    | This setting determines the email template used by Plink to send emails.
    | Switch to 'plink::mail.notification' if you prefer to use the default 
    | Laravel notification template.
    |
    */

    'template' => 'plink::mail.plink',
    // 'template' => 'plink::mail.notification',
];

Usage

Laravel Breeze Livewire Example

1. Replace the Breeze provided App\Livewire\Forms\LoginForm::authenticate method with a sendEmail method that runs the SendPlink action. Also be sure to remove password from the LoginForm's properties.

    // app/Livewire/Forms/LoginForm.php

    use BenBjurstrom\Plink\Actions\SendPlink;
    use BenBjurstrom\Plink\Exceptions\PlinkThrottleException;
    use BenBjurstrom\Plink\Models\Plink;
    //...

    #[Validate('required|string|email')]
    public string $email = '';

    #[Validate('boolean')]
    public bool $remember = false;
    //...

    public function sendEmail(): void
    {
        $this->validate();

        $this->ensureIsNotRateLimited();
        RateLimiter::hit($this->throttleKey(), 300);

        try {
            (new SendPlink)->handle($this->email, $this->remember);
        } catch (PlinkThrottleException $e) {
            throw ValidationException::withMessages([
                'form.email' => $e->getMessage(),
            ]);
        }

        RateLimiter::clear($this->throttleKey());
    }

1. Update resources/views/livewire/pages/auth/login.blade.php such that the login function calls our new sendEmail method and redirects back with a status confirmation. You can also remove the password input field in this same file.

    public function login(): void
    {
        $this->validate();

        $this->form->sendEmail();

        redirect()->back()->with(['status' => 'Login link sent!']);
    }

Laravel Breeze Inertia Example

1. Replace the Breeze provided App\Http\Requests\Auth\LoginRequest::authenticate method with a sendEmail method that runs the SendPlink action. Also be sure to remove password from the rules array.

    // app/Http/Requests/Auth/LoginRequest.php

    use BenBjurstrom\Plink\Actions\SendPlink;
    use BenBjurstrom\Plink\Exceptions\PlinkThrottleException;
    use BenBjurstrom\Plink\Models\Plink;
    //...
    
    public function rules(): array
    {
        return [
            'email' => ['required', 'string', 'email']
        ];
    }
    //...
    
    public function sendEmail(): Void
    {
        $this->ensureIsNotRateLimited();
        RateLimiter::hit($this->throttleKey(), 300);

        try {
            (new SendPlink)->handle($this->email, $this->remember);
        } catch (PlinkThrottleException $e) {
            throw ValidationException::withMessages([
                'email' => $e->getMessage(),
            ]);
        }

        RateLimiter::clear($this->throttleKey());
    }

1. Update the App\Http\Controllers\Auth\AuthenticatedSessionController::store method to call our new sendEmail method and redirect back with a status confirmation.

    // app/Http/Controllers/Auth/AuthenticatedSessionController.php

    public function store(LoginRequest $request): RedirectResponse
    {
        $request->sendEmail();

        return back()->with(['status' => 'Login link sent!']);
    }

1. Remove the password input field from the resources/js/Pages/Auth/Login.vue file.

Everything else is handled by the package components.
