Answer 1

Use View::composer('*',) to use Auth in all view .
use Illuminate\Support\Facades\View;
.........
public function boot()
{
View::composer('*', function($view)
{
if (Auth::check()){
$project = Project::where('user_id',Auth::id() )->count();
}
});
You can understand it as after authentication before view render you need to check between these not before.

Auth will always try to get the id even user is logged in or not. In case user is not logged in then it will give you non-object error because nothing is there to get via User model object.
public function boot()
{
if (Auth::check()) {
$userid = Auth::user()->id;
Log::info('userid :', [$userid]);
$project = Project::where('user_id',Auth::user()->id)->count();
}
}
Good luck.

In the boot() method of your service providers, you should only bootstrap your application and not perform any action regarding looking up or outputting data. You can do this in the register() method of your providers, if it is really necessary to do it in a service provider. A better place would probably be a controller or a command anyway, though.
Using Auth::user() directly is dangerous as well, because there might be no user authenticated in your app. You can instead perform a if(Auth::check()) { ... } before accessing the user with Auth::user(), or, which in your case would be sufficient, you can access the user id with Auth::id(). It will also return null if no user is available, i.e. Auth::check() === false.
