Laravel，将app.blade.php文件的逻辑放在哪里？

我正在为我的新项目使用Laravel5，我希望遵循最佳实践。我的布局包装为

resources/views/app.blade.php

，它“生成”每个视图。我需要在app.blade.php中显示一些动态生成的数据，我应该将生成数据的逻辑放在哪里？对于任何其他视图，我都会在相应的控制器中执行，但对于整个应用程序

谢谢

<?php namespace App\Http\Composers;

use Illuminate\Contracts\View\View;
use Illuminate\Users\Repository as UserRepository;

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->users = $users;
    }

    /**
     * Bind data to the view.
     *
     * @param  View  $view
     * @return void
     */
    public function compose(View $view)
    {
        $view->with('count', $this->users->count());
    }

}

View::composer(['profile', 'dashboard'], 'App\Http\ViewComposers\MyViewComposer');
