Singleton Pattern Development Tutorials, Guides & Insights

   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
               ];
           });
       }
   }

Add the provider to the providers array in config/app.php:

const RevealingModule = (function() {
    let privateVariable = 'I am private';

    function privateFunction() {
        console.log(privateVariable);
    }

    function publicFunction() {
        privateFunction();
    }

    // Reveal public pointers to private functions and properties
    return {
        publicFunction: publicFunction
    };
})();

RevealingModule.publicFunction(); // Output: I am private

• More readable and consistent code.
• Clear definition of what is public and what is private.
