You can configure the package by editing the config/n-plus-one.php file. This file allows you to set the threshold for detecting N+1 queries, notification preferences, and more.

<?php

return [
    
    // Whether or not to enable the N+1 Detector
    'enabled' => env('NPLUSONE_ENABLED', true),
    
    // The number of queries below which no alert will be triggered
    'queries_threshold' => env('NPLUSONE_QUERIES_THRESHOLD', 50),
    
    // The number of queries below which no detector will be triggered
    'detector_threshold' => env('NPLUSONE_DETECTOR_THRESHOLD', 10),
    
    // The number in minutes a n+1 query will be stored in memory before being discarded. So it won't repeat itself
    'cache_lifetime' => env('NPLUSONE_CACHE_LIFETIME', 14400), // 10 days
      
    // Slack webhook url for N + 1 Detector
    'slack_webhook_url' => env('NPLUSONE_SLACK_WEBHOOK_URL', ''),

    // Custom webhook url for N + 1 Detector
    'custom_webhook_url' => env('NPLUSONE_CUSTOM_WEBHOOK_URL', ''),

    // notification email address for N + 1 Detector
    'notification_email' => env('NPLUSONE_NOTIFICATION_EMAIL', '[email protected]'), // also possible: '[email protected],[email protected]'

    // notification email subject for N + 1 Detector
    'notification_email_subject' => env('NPLUSONE_NOTIFICATION_EMAIL_SUBJECT', 'N+1 Detector Notification'),

    // Dashboard Middleware for N + 1 Detector
    'dashboard_middleware' => env('NPLUSONE_DASHBOARD_MIDDLEWARE', ['web', 'auth']),

    // Dashboard Pagination for N + 1 Detector
    'dashboard_records_pagination' => env('NPLUSONE_DASHBOARD_RECORDS_PAGINATION', 10),

];

The package automatically listens to your database queries and detects N+1 issues in real-time. When an N+1 query is detected, it logs the query details and optionally sends notifications.

Access the rich admin dashboard to view all N+1 warnings:

Route::get('/n-plus-one-dashboard', [NPlusOneDashboardController::class, 'index'])->name('n-plus-one.dashboard');

The dashboard provides a comprehensive view of all detected N+1 queries, including SQL statements, occurrences, locations, and suggested fixes.

Configure notifications to be sent via Slack, webhook, or email. Set your notification preferences in the config/n-plus-one.php file to stay informed about N+1 issues in your application.

    // Slack webhook url for N + 1 Detector
    'slack_webhook_url' => env('NPLUSONE_SLACK_WEBHOOK_URL', ''),

    // Custom webhook url for N + 1 Detector
    'custom_webhook_url' => env('NPLUSONE_CUSTOM_WEBHOOK_URL', ''),

    // notification email address for N + 1 Detector
    'notification_email' => env('NPLUSONE_NOTIFICATION_EMAIL', '[email protected]'), // also possible: '[email protected],[email protected]'

Detailed Query Insights

The package provides detailed insights into each detected N+1 query, including the class and methods involved. This helps you quickly pinpoint the source of the problem and implement a fix.
