Answer 1

you can use @auth @endauth

@auth
     <li class="nav-item">
          <a class="nav-link" href="{{ route('download') }}">{{ __('download') }}</a>
     </li>
@endauth

Answer 2

alernative you can use optional global helper

optional(Auth::user())->$anyProperty;

Answer 3

If you user is guest then you have no record on DB, so first check if has been authenticated or not.

change this line:

@if(auth::user()->user)

to this

@if(Auth::check())
