I think we should exclude App\ from here as we support custom namespace via APP_NAMESPACE.

That change may less happen, also, composer autoload doesn't break codeigniter 4 autoloader, that will be a fallback namespace.

We cannot change app folder name. Because the composer's path overwrite the config in Config\Autoload.

@samsonasik What's the benefit to use composer autoload?

As far as i remember, with prioritize composer autoload when possible, it will got benefit for composer itself (eg: classmap on dump-autoload -o).

Probably in case of changing app directory, documentation need to be updated to change composer.json as well.

It's time to abandon the internal autoloader and use only the composer.

@samsonasik Thank you. I'm not sure that composer's autoloader has priority. I'll check.

@iRedds Do you mean the zip installation will be discontinued?

One core tenet of CI has always been the ability to download a zip and not worry about anything. From my experience on the forums since v4 has been released this is still the case for a large chunk of users.

We must always remember the broader user-base and CodeIgniter's history. While we don't want to be completely beholden to old ways, we do need to pay attention to the users, and not alienate a broad group of them for no discernible gain.

This could have been avoided if we did not have the autoload.psr4 section. I tried with codeigniter4/codeigniter4 renaming app/ to myapp/, and the only thing I need to change is the FCPATH in spark and public/index.php.

@kenjis Do you need a zip installation?
@lonnieezell The CI history says use an array for configuration files. =)
Do you have zip download data to say that this is the majority?
For example, Composer generated 37,735 installs in the last 30 days, of which 1,311 were made today alone.

@iRedds Personally I never use zip installation, but I don't say drop it soon.
CI is the last major framework that can be installed without Composer.
I think drop of the Zip installation should be carefully considered.

I see users using Zip who report GitHub issues sometime.

@kenjis Composer.phar and the installed framework can be added to the zip.

The path is from Composer, but
it seems CI's autoloader loads App\Controllers\Home. CI 4.1.8 appstarter.

No, @samsonasik is correct.
If I run composer dump-autoload -o, 'App\\Controllers\\Home' is included in Composer classmap file,
and CI4 autoloader uses it.

@iRedds

Composer.phar and the installed framework can be added to the zip.

I don't think it is good idea.
It forces users to use Composer without permission.
