How to organize files when there is a public part and an admin panel?

Question

Laravel

Am I correct if I think that the best solution would be to divide the areas of responsibility as much as possible and duplicate the code to a certain extent? Or am I mistaken?

Http/
....Controllers/
........Admin/
............PostController.php
........Site/
....... .....PostController.php
....Requests/
........Admin/
............StorePostRequest.php
........... .UpdatePostRequest.php
........Site/
............StorePostRequest.php
............UpdatePostRequest.php
....Resources/
........Admin/
............PostResource.php
........Site/
............PostResource.php

Answer 1

Could be so. As a result, you will receive 2 applications.
I wouldn't bother with duplication. You never know what else to come up with. If you start crossing then it will be painful to refine.
