Yes, it is possible to move a PHP application inside a Laravel package. You can place the application code inside the src folder of the package. To create a route for the home page of the package, you can add the following code to the routes/web.php file of the package:
Route::get('/home', function () {
return view('home');
});
You can also create a controller for the home page and add the following code to the routes/web.php file:
Route::get('/home', 'HomeController@index');
