Is it possible to make relative paths in Laravel?

Question

Laravel

There is a site. Laravel is located in the / sub folder. Those. index.php is in /sub/public.
For routes to work, you need to write

$app->get('sub/public', function () use ($app) {
    return $app->version();
});

Is it possible to make it so that it is not necessary to write the path in its entirety, but only

$app->get('/', function () use ($app) {
    return $app->version();
});

Answer 1

$router->group(['prefix' => 'sub'], function ($router) {
  $router->get('public', function ($router) {
      return $router->version();
  });
});

Answer 2

The Route::get('/') route just points to the public folder of the Laravel project.
That is, in nginx (or whatever you have) you specify the site root as .../sub/public and everything works.
Or did I misunderstand the question?
