Controller not found

this is the first time I use Codeigniter 4

I'm already installed codeigniter 4 with composer or manual

already copy index.php and .htaccess to root when manual install and run

already run with php start spark serve too

already set baseurl  http://localhost/ci4

welcome_message is success run when I Write in URL localhost:8080 or localhost/ci4

but when I write in URL  localhost:8080/home/index  with spark serve, show 404 - File Not Found

and when I write in URL  localhost/ci4/home/index  still show 404 - File Not Found

anyone please help me....

the urls you have outlined work on my web app on desktop and running using php spark serve:

Code:

app/Config/Routes.php I have
$routes->setAutoRoute(false);
$routes->get('/', 'Home::index');


//controller home i have :
public function Index()
    {
                
$this->cachePage(DAY);
        //got above from foundations book
        
        $data = [
                'title'  => 'home page ',
                
        ];
            
       echo view('home',$data);
      
        
    }

i didn't touch .htaccess , i did  get latest  index.php from vendor/public directory and stick it in  webapp/public
also latest spark executable from vendor and replace the one in web root, with it . Thats all

CMS CI4     I use Arch Linux by the way 

already copy index.php and .htaccess to root when manual install and run

Please don't copy these files. You don't need to do.

You need to define routes.
