The best way would be sharing the variable using View::share('var', $value);

Problems with composing using "*":

Consider following approach:

<?php
// from AppServiceProvider::boot()
$viewFactory = $this->app->make(Factory::class);

$viewFacrory->compose('*', GlobalComposer::class);

From an example blade view:

  @for($i = 0; $i<1000; $i++)
    @include('some_partial_view_to_display_i', ['toDisplay' => $i])
  @endfor

What happens?

The GlobalComposer class is instantiated 1000 times using App::make.
The event composing:some_partial_view_to_display_i is handled 1000 times.
The compose function inside the GlobalComposer class is called 1000 times.

But the partial view some_partial_view_to_display_i has nothing to do with the variables composed by GlobalComposer but heavily increases render time.

Best approach?

Using View::share along a grouped middleware.

Route::group(['middleware' => 'WebMiddleware'], function(){
  // Web routes
});

Route::group(['prefix' => 'api'], function (){

});

class WebMiddleware {
  public function handle($request)
  {
    \View::share('user', auth()->user());
  }
}

Update

If you are using something that is computed over the middleware pipeline you can simply listen to the proper event or put the view share middleware at the last bottom of the pipeline.

In the documentation      Typically  you would place calls to the share method within a service   provider s boot method  You are free to add them to the   AppServiceProvider or generate a separate service provider to house   them    I m agree with Marwelln  just put it in AppServiceProvider in the boot function   public function boot         View  share  youVarName    1  2  3        I recommend use an specific name for the variable  to avoid confussions or mistakes with other no  global  variables

This target can achieve through different method   1  Using BaseController  The way I like to set things up  I make a BaseController class that extends Laravel   s own Controller  and set up various global things there  All other controllers then extend from BaseController rather than Laravel   s Controller    class BaseController extends Controller     public function   construct             its just a dummy data object       user   User  all            Sharing is caring     View  share  user    user           2  Using Filter  If you know for a fact that you want something set up for views on every request throughout the entire application  you can also do it via a filter that runs before the request     this is how I deal with the User object in Laravel   App  before function  request         Set up global user object for views   View  share  user   User  all           OR  You can define your own filter  Route  filter  user-filter   function         View  share  user   User  all           and call it through simple filter calling   Update According to Version 5    3  Using Middleware  Using the View  share with middleware  Route  group   middleware    gt   SomeMiddleware    function         routes        class SomeMiddleware     public function handle  request           View  share  user   auth  - gt user             4  Using View Composer  View Composer also help to bind specific data to view in different ways  You can directly bind variable to specific view or to all views  For Example you can create your own directory to store your view composer file according to requirement  and these view composer file through Service provide interact with view   View composer method can use different way  First example can look alike   You could create an App Http ViewComposers directory    Service Provider  namespace App Providers  use Illuminate Support ServiceProvider  class ViewComposerServiceProvider extends ServiceProvider       public function boot             view  - gt composer  ViewName   App Http ViewComposers TestViewComposer              After that  add this provider to config app php under  providers  section   TestViewComposer  namespace App Http ViewComposers   use Illuminate Contracts View View   class TestViewComposer        public function compose View  view             view- gt with  ViewComposerTestVariable    Calling with View Composer Provider              ViewName blade php  Here you are       ViewComposerTestVariable     This method could help for only specific View  But if you want trigger ViewComposer to all views  we have to apply this single change to ServiceProvider   namespace App Providers  use Illuminate Support ServiceProvider  class ViewComposerServiceProvider extends ServiceProvider       public function boot             view  - gt composer      App Http ViewComposers TestViewComposer              Reference  Laravel Documentation  For Further Clarification Laracast Episode  If still something unclear from my side  let me know

The documentation is hear https   laravel com docs 5 4 views view-composers but i will break it down   Look for the directory app Providers in the root directory of your application and create the file ComposerServiceProvider php and copy and past the text below into it and save it    lt  php     namespace App Providers      use Illuminate Support Facades View      use Illuminate Support ServiceProvider       class ComposerServiceProvider extends ServiceProvider                             Register bindings in the container                       return void                public function boot                    Using class based composers            View  composer               profile    App Http ViewComposers ProfileComposer                         Using Closure based composers            View  composer  dashboard   function   view                                                    Register the service provider               return void            public function register                             From the root of your application open Config app php and look for the Providers section in the file and copy and past this  App Providers ComposerServiceProvider   to the array    By doing this  we have created the Composer Service Provider  When you run your application with the view Profile like so http   yourdomain something profile  the service provider ComposerServiceProvider is called and the class App Http ViewComposers ProfileComposer is instantiated calling the method Composer due to the code below inside the boot method or function       Using class based composers     View  composer      profile    App Http ViewComposers ProfileComposer         If you refresh your application you will get an error because the class App Http ViewComposers ProfileComposer does not exist yet  Now lets create it    Go to the directory path app Http   Create the directory called ViewComposers Create the file ProfileComposer php     class ProfileComposer                 The user repository implementation               var UserRepository            protected  users                 Create a new profile composer               param  UserRepository   users        return void            public function   construct UserRepository  users                   Dependencies automatically resolved by service container             this- gt users    users                       Bind data to the view               param  View   view        return void            public function compose View  view                 view- gt with  count    this- gt users- gt count                Now go to your view or in this case Profile blade php and add      count      and that will show the count of users on the profile page    To show the count on all pages change     Using class based composers    View  composer       profile    App Http ViewComposers ProfileComposer       To      Using class based composers    View  composer            App Http ViewComposers ProfileComposer

I found this to be the easiest one  Create a new provider and user the     wildcard to attach it to all views  Works in 5 3 as well  -    lt  php  namespace App Providers   use Illuminate Http Request  use Illuminate Support ServiceProvider   class ViewServiceProvider extends ServiceProvider                  Bootstrap the application services          return void             public function boot                 view  - gt composer      function   view                         user   request  - gt user                  view- gt with  user    user                                     Register the application services                 return void             public function register

You have two options  1  Share via  Boot function in App Providers AppServiceProvider  public function boot       view  - gt share  key    value       And access  key variable in any view file  Note  Remember that you can t access current Session  Auth  Route data here  This option is good only if you want to share static data  Suppose you want to share some data based on the current user   route  or any custom session variable you won t be able to do with this  2  Use of a helper class  Create a helper class anywhere in your application and register it in Alias array in app php file in config folder    aliases    gt                Helper    gt  App HelperClass Helper  class       and create Helper php in HelperClass folder within App folder  namespace App HelperClass       class Helper       public static function Sample                   Your Code Here          and access it anywhere like Helper  Sample    You will not be restricted here to use Auth  Route  Session  or any other classes

You can either create your own service provider  ViewServiceProvider name is common  or you can use the existing AppServiceProvider   In your selected provider  put your code in the boot method   public function boot         view  - gt share  data    1  2  3        This will make a  data variable accessible in all your views   If you rather want to use the facade instead of the helper  change view  - gt  to View   but don t forget to have use View  at the top of your file

Inside your config folder you can create a php file name it for example  variable php  with content below    lt  php    return        versionNumber    gt   122231          Now inside all the views you can use it like  config  variable versionNumber
