Change localhost:8080 to custom domain CI4

Hi,

I'm quite new in CI4, but use CI3 for view years.

I saw a video on youtube where someone change app.php to set CI4 custom domain and remove index.php

here's the link

Code:

https://www.youtube.com/watch?v=yoKTE5J5T7g

this is how exactly i want CI4 work in my localhost (I'm using apache2)

but, since i saw documentation of CI4 where i can run

Code:

php spark serve

and my CI4 run when accesed from

Code:

localhost:8080

is there any way to change that

Code:

localhost:8080

to something like

Code:

http://localhost/mypCI4

so i can access my ci project with "php spark serve" but with my custom domain in localhost ?

im trying to add in .env something like

Code:

app.baseURL=http://localhost/mypCI4

but it's not working

Thanks in advance
