Optimizing Performance in Laravel by Centralizing Data Loading

npm install jest @testing-library/react @testing-library/react-hooks @reduxjs/toolkit

Write unit tests for usersSlice:

   public function testJobHandlesConcurrency()
   {
       for ($i = 0; $i < 5; $i++) {
           ProcessOrderJob::dispatch($orderId);
       }

       $this->assertDatabaseHas('orders', ['id' => $orderId, 'status' => 'processed']);
   }

• Use Redis locks to prevent concurrent access to shared resources.
• Wrap critical operations in database transactions to maintain data consistency.
• Implement unique jobs to avoid duplicate processing.
• Monitor job performance and behavior using Laravel Horizon.

   <p>App Mode: {{ $globalConfig['app_mode'] }}</p>
   <p>Contact: {{ $globalConfig['support_email'] }}</p>
