Basic Setup

Update your bootstrap/app.php to use the exception notifier:

<?php

use Damku999\ExceptionNotifier\JsonExceptionHandler;
use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        api: __DIR__.'/../routes/api.php',
        commands: __DIR__.'/../routes/console.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware) {
        //
    })
    ->withExceptions(function (Exceptions $exceptions) {
        $exceptions->render(function (Throwable $e) {
            return app(JsonExceptionHandler::class)->handle($e);
        });
    })->create();

Advanced Configuration

Edit config/exception_notifier.php for advanced options:

return [
    // Enable/disable globally
    'enabled' => env('EXCEPTION_EMAIL_ENABLED', false),

    // Silent mode in local environment
    'silent_in_local' => env('EXCEPTION_EMAIL_SILENT_LOCAL', true),

    // Email recipients
    'recipients' => array_filter(array_map('trim', explode(',', env('EXCEPTION_EMAIL_TO', '')))),

    // Fallback recipients if none specified
    'fallback_recipients' => ['admin@example.com'],

    // Rate limiting
    'max_emails_per_signature_per_hour' => env('EXCEPTION_EMAIL_MAX_PER_HOUR', 10),
    'rate_limit_window' => env('EXCEPTION_EMAIL_RATE_WINDOW', 3600),

    // Ignored exceptions (won't send emails)
    'ignored_exceptions' => [
        \Illuminate\Validation\ValidationException::class,
        \Symfony\Component\HttpKernel\Exception\NotFoundHttpException::class,
        \Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException::class,
        \Illuminate\Auth\AuthenticationException::class,
    ],

    // Critical exceptions (bypass rate limits)
    'critical_exceptions' => [
        \Illuminate\Database\QueryException::class,
    ],

    // Bot user agents to ignore
    'ignored_bots' => [
        'googlebot', 'bingbot', 'crawler', 'spider', 'bot',
    ],

    // Include context data in emails
    'include_request_data' => true,
    'include_user_data' => true,
    'include_stack_trace' => true,
    'max_stack_trace_depth' => 10,

    // Send suppression notice when rate limit reached
    'send_suppression_notice' => true,
];

🚀 Usage

Automatic Exception Handling

Once configured in bootstrap/app.php, the package automatically catches and notifies you of exceptions:

// Any uncaught exception will trigger an email notification
throw new \Exception('Something went wrong!');

// Validation exceptions are ignored by default (configurable)
throw ValidationException::withMessages(['email' => 'Invalid email']);

// Database exceptions are marked as critical (always sent)
DB::table('non_existent')->get(); // Triggers critical email

Manual Exception Notification

You can manually trigger exception notifications:

use Damku999\ExceptionNotifier\Facades\ExceptionNotifier;

try {
    // Your code
} catch (\Throwable $e) {
    ExceptionNotifier::notify($e);

    // Continue with your error handling
}

Checking Rate Limits

use Damku999\ExceptionNotifier\Facades\ExceptionNotifier;

// Check if rate limit exceeded for specific exception
$signature = ExceptionNotifier::generateSignature($exception);
$exceeded = ExceptionNotifier::isRateLimitExceeded($signature);

// Get current count for signature
$count = ExceptionNotifier::getRateLimitCount($signature);

// Get all rate limit statuses
$statuses = ExceptionNotifier::getRateLimitStatus();

🔧 Artisan Commands

View Rate Limit Status

View current rate limit status for all exception signatures:

php artisan exception:rate-limit-status

Output:

┌──────────────────────────────────────────────────────────────┬───────┬─────┬──────────┐
│ Exception Signature                                          │ Count │ Max │ TTL (s)  │
├──────────────────────────────────────────────────────────────┼───────┼─────┼──────────┤
│ Exception:app/Http/Controllers/UserController.php:45         │ 8     │ 10  │ 2847     │
│ QueryException:app/Models/User.php:123                       │ 15    │ 10  │ 1523     │
└──────────────────────────────────────────────────────────────┴───────┴─────┴──────────┘

Clear Rate Limits

Clear all rate limits:

php artisan exception:clear-rate-limits

Clear specific signature:

php artisan exception:clear-rate-limits --signature="Exception:app/Http/Controllers/UserController.php:45"

Test Exception Emails

Send a test exception email:

php artisan exception:test

Send test with custom exception type:

php artisan exception:test --type=critical

📧 Email Templates

The package includes two beautiful, responsive email templates:

Exception Notification Email

Sent when an exception occurs (within rate limits):

• Exception Summary - Class, message, file, line, signature
• Stack Trace - Formatted call stack with file/line numbers
• Request Details - URL, method, IP, user agent
• User Context - Authenticated user information
• Environment Info - Environment name and timestamp
• Rate Limit Status - Current count vs maximum allowed

Rate Limit Suppression Email

Sent once when rate limit is reached:

• Rate Limit Info - Signature, max count, time remaining
• What This Means - Explanation of suppression
• Action Required - Steps to investigate and resolve
• Helpful Commands - CLI commands to manage rate limits

Customizing Templates

Publish the views and edit them:

php artisan vendor:publish --tag="exception-notifier-views"

Templates location: resources/views/vendor/exception-notifier/

Customizing Email Branding

Override the branding configuration:

// In your AppServiceProvider or config
config([
    'exception_notifier.branding' => [
        'email_logo' => 'images/logo.png',
        'primary_color' => '#007bff',
        'text_color' => '#333333',
        'footer_text' => 'Your Company Name',
        'support_email' => 'support@example.com',
    ],
]);

🧪 Testing

Run the test suite:

composer test

Run tests with coverage:

composer test:coverage

📊 Exception Signature Format

The package generates unique signatures for each exception using:

Format: ExceptionClass:FilePath:LineNumber
Example: Exception:app/Http/Controllers/UserController.php:45

This ensures:

• ✅ Same exception at same location = same signature
• ✅ Rate limiting works per unique error
• ✅ Different locations = different signatures

🔒 Security

Preventing Infinite Loops

The package is designed to never break your application:

// In JsonExceptionHandler
try {
    $this->notifierService->notify($e);
} catch (Throwable $notificationError) {
    // Silently fail if notification fails
    Log::error('Exception notification failed', [
        'error' => $notificationError->getMessage(),
    ]);
}

Bot Protection

Automatically ignores exceptions from bots to prevent spam:

'ignored_bots' => [
    'googlebot', 'bingbot', 'slurp', 'crawler', 'spider',
    'bot', 'facebookexternalhit', 'twitterbot', 'whatsapp',
    'telegram', 'curl', 'wget',
],
