Laravel Livewire enum type hint

By default, if you type hint an enum in a Livewire component, you'll get an error. Livewire doesn't support enum type hints out of the box. We can fix this with a lifecycle hook:

use Livewire\Component;

class YourComponent extends Component
{   
    public UserRole $user_role = UserRole::ADMIN;

    public function updatingUserRole(&$value)
    {
        $value = $value instanceof UserRole ? $value : UserRole::from($value);
    }
}

The updatingUserRole lifecycle hook can change the value before the property is set. $value is passed by reference so that we can cast it to an enum before Livewire assigns it to the property.
