Laravel Programming Tutorials, Guides & Best Practices

We’ll address these issues with practical solutions.

• Duplicate entries in the database.
• Incorrect data due to overwrites.
• Processes failing intermittently when run concurrently.

For extremely large datasets, consider switching from Eloquent to raw queries with the Query Builder:

$posts = DB::table('posts')
    ->join('users', 'posts.author_id', '=', 'users.id')
    ->select('posts.*', 'users.name as author_name')
    ->get();

   namespace App\Http\Controllers;

   use Illuminate\Support\Facades\View;

   class ExampleController extends Controller
   {
       public function index()
       {
           $globalPreferences = View::shared('globalPreferences');

           return view('example', [
               'apiLimit' => $globalPreferences['api_limit'],
               'appMode' => $globalPreferences['app_mode'],
           ]);
       }
   }

If the data needs to change during the application lifecycle (e.g., a feature toggle), you can update it dynamically.

• Application Limits: Data like maximum uploads or API rate limits are shared globally.
• Feature Toggles: Enable or disable application features dynamically.
• Global Preferences: Shared preferences such as the preferred user interface theme.

Using the singleton pattern, we’ll make this data globally accessible and reusable.
