Hi @odan, thank you for the response.
just downloaded your code from github, yes BasePathMiddleware added. As said everything works fine when i start the php server inside public/index of my slim4 project directory like `php -S 0.0.0.0:8080 -t public public/index.php

but i get 404 when i start the server outside the slim4 folder like php -S 0.0.0.0:8080
i am wondering how the program is determining which folder to run in browser because there are so many other php project.

@blacktornado You screenshot shows that you start the php internal webserver directly in your Desktop directory. I'm sure this is not the correct path where you have stored the public/ directory. Change into the project directory and then into the public/ directory.
I think in your specific case it should be:

cd c:\Users\black\Desktop\slim
php -S localhost:8000 -t public

You can also try this:

cd c:\Users\black\Desktop\slim\public
php -S localhost:8000

Then navigate to: http://localhost:8000/

yes @odan i understand your point as it is looking for the public directory which has index.php, as i am using php internal web server.

coming to another scenario where i have web server that points to htdocs and my slim is inside htdocs/somefolder/slim i am hitting the url with 10.xxx.xxx.x:port/somefolder/slim the request lands successfully to public/index.php from there it goes to bootstrap.php to container.php and finally lands to routes.php where if i do a var_dump($app) it gives me resultset but i am getting 404 error with

Type: Slim\Exception\HttpNotFoundException
code: 404
Message: Not Found
File: /www/zendphp7/htdocs/somefolder/slim/vendor/slim/slim/Middleware/RoutingMiddleware.php

to make it work if i remove this line return function(App $app){ from router.php and again add this two lines in router.php
$app = AppFactory::create();
$app->setBasePath('/somefolder/slim');
its working.

@blacktornado I think it makes no sense to create a new $app instance, because per request there should be only one Slim instance.

This is a great tutorial, thank you so much!

Is there any particular reason to separate the Read and Create into separate repositories and services? In this example, would it be against design patterns to use a single UserRepository containing both insertUser and getUserById methods? Similarly, is it suggested to not combine the Service methods into a single UserService?

Hi @marcusball Please note that this is not an Active-Record (anti-) pattern. The shown pattern follows Command–query separation (CQS) on routing level. So read and write access is separated. To respect the SOLID (see SRP) principles, the service class is responsible only for one specific task (use case) and not more.
