Laravel Programming Tutorials, Guides & Best Practices

Consider an application where you need to:

• Share app-wide settings (e.g., theme or API limits) with all views.
• Make user-specific preferences (e.g., notification settings) accessible to controllers and views.
• Dynamically load data blocks like navigation menus or notifications.

The shared data passed from controllers can now be accessed directly in Blade templates.

   @if ($userRole === 'admin')
       <p>Welcome, Admin!</p>
   @else
       <p>Welcome, {{ $userRole }}!</p>
   @endif

   @if ($featureToggles['file_uploads_enabled'])
       <p>File uploads are currently enabled.</p>
   @else
       <p>File uploads are disabled.</p>
   @endif

   @if ($appConfig['app_mode'] === 'maintenance')
       <p>The application is under maintenance. Please check back later.</p>
   @else
       <p>The application is live.</p>
   @endif

You can access the shared data singleton using the app() helper or dependency injection.

In any controller, retrieve the shared data:
