duplicated query

You can use view composer as a singleton. Then your query will be fetch only once.

<?php

namespace App\Http\View\Composers;

use App\Category;
use Illuminate\View\View;

class MenuComposer
{
    protected $categories;

    public function compose(View $view)
    {
        if (! $this->categories) {
            $this->categories = Category::all();
        }

        $view->with([
            'categories' => $this->categories
        ]);
    }
}

<?php

namespace App\Providers;

use App\Http\View\Composers\MenuComposer;
use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;

class ViewServiceProvider extends ServiceProvider
{
    /**
     * Register services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton(MenuComposer::class);
    }

    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        View::composer([
            'view.where.you.use.that.categories',
            'another.one'
        ], MenuComposer::class);
    }
}
