Passing authentication state to the frontend

We now have a complete mechanism for logging users in and out of Vuebnb. However, the frontend app is not yet aware of the user's authentication state. Let's remedy that now so we can add authentication-based features to the frontend.

 auth meta property

We'll begin by adding the authentication state to the meta information we pass through in the head of each page. We'll utilize the Auth facade check method, which returns true if the user is authenticated, and assign this to a new auth property.

app/Http/Controllers/ListingController.php:

...
use Illuminate\Support\Facades\Auth;

class ListingController extends Controller
{
  ...

  private function add_meta_data($collection, $request)
  {
    return $collection->merge([
      'path' => $request->getPathInfo(),
      'auth' => Auth::check()
    ]);
  }
}

We'll also add an auth property to our Vuex store. We'll mutate it from the addData method which, as you'll recall from the previous chapter...
