Handling Race Conditions in Laravel Jobs and Queues

The N+1 query problem is a common performance issue that occurs when Laravel executes unnecessary or repetitive database queries. This tutorial will help you identify and resolve N+1 query issues in your Laravel applications using eager loading, lazy loading, and debugging tools like Laravel Debugbar.

The N+1 query problem happens when your application executes one query to retrieve a parent dataset, followed by multiple additional queries to fetch related data for each parent record.

In Laravel applications, certain data—such as global settings, user roles, or feature toggles—is accessed frequently across multiple parts of the app. If not handled efficiently, repeated queries for the same data can impact performance. Centralizing data loading ensures that this data is retrieved once and reused wherever needed, improving performance and maintainability.

This tutorial demonstrates how to optimize data loading in Laravel by using centralized techniques such as caching, service providers, and the singleton pattern.

• Centralized Data Logic: Service providers act as a single source for global data, simplifying management and maintenance.
• Performance Optimization: Shared data is loaded once and reused throughout the application, reducing database queries.
• Easy Access: Data can be accessed in Blade templates, controllers, and middleware without additional queries.

By using service providers, you’ve centralized the management of global data in Laravel. This approach improves code organization, boosts performance, and ensures consistency across your application. Whether it's API limits, feature toggles, or application preferences, service providers make managing shared data seamless.

Open the generated file in app/Providers/SharedDataServiceProvider.php and define a singleton for the shared data:

   namespace App\Providers;

   use Illuminate\Support\ServiceProvider;

   class SharedDataServiceProvider extends ServiceProvider
   {
       public function register()
       {
           $this->app->singleton('sharedData', function () {
               return (object) [
                   'maxUploads' => 20, // Maximum file uploads allowed
                   'apiRateLimit' => 100, // API requests per minute
                   'theme' => 'dark', // Default UI theme
               ];
           });
       }
   }
