Laravel 5 のすべてのビューでデータにグローバルにアクセスできるようにするにはどうすればよいですか?

class BaseController extends Controller
{
    public function __construct()
    {
        // Access your global data here
        $user = User::all();
        View::share('user', $user);
    }
}

App::before(function($request)
{
    // Access your global data here
    View::share('user', User::all());
});

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

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

// Service Provider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer("*", "App\Http\ViewComposers\TestViewComposer");
    }
}

// View Composer
namespace App\Http\ViewComposers;

use Illuminate\Contracts\View\View;

class TestViewComposer {

    public function compose(View $view) {
        $view->with('ViewComposerTestVariable', "Calling with View Composer Provider");
    }
}
