I understand that you need to write all the rules for PSR-4 in composer.json or delete everything. Although there was no such notification before.

Cannot reproduce.

It seems in your composer.json autoload.psr-4 section you have set mapping for App\ and CodeIgniter\

[neznaika0]

Yes, default in appstarter.

Your version composer?

[paulbalandan]

Ok, I cannot also reproduce:

$ ~/Workspace/appstarter composer update                                                                                  ✔

In Windows all done. PHP 8.2 Composer 2.7.6
Hmm...
I install as app in system. Maybe because of this?

[neznaika0]

It may be worth waiting, there is already a release 2..7.7

composer/class-map-generator#8

[kenjis]

I could reproduce with this repository and Composer version 2.7.7 2024-06-10 22:11:12.
But the all warnings are correct.

I sent a PR #8962 for this repository, but how can we solve the issue on appstarter?

[neznaika0]

You need to add a namespace:

        "psr-4": {
            "App\\": "app/",
            "Config\\": "app/Config"
        },

or clear the property:

    "autoload": {
        "exclude-from-classmap": [
            "**/Database/Migrations/**"
        ]
    },

In any case, the code works based on the built-in autoloader.

[kenjis]

The current autoload in composer.json comes from #8005 and #8569

[kenjis]

I sent #8963 for appstarter.

[neznaika0]

I did not understand the reason for removing Config for performance from #8005. I do not know all the internal details.

Why is this important for composer?
Is it worth abandoning psr in composer?
Is json preferable to an autoloader? So that the autoloader always works.

I know that the editor understands the PSR from composer and gives hints. And vscode remembers any namespaces when declaring.

[kenjis]

@neznaika0 I'm not sure that I get what you say correctly.

If you don't get the change in #8569, it is because,
if vendor/codeigniter4/codeigniter4/composer.json has "Config\\": "app/Config/",
vendor/codeigniter4/codeigniter4/app/Config/* will be loaded.
But these files should not be loaded at all.

.
├── app/
│   ├── Config/
├── composer.json
├── vendor/
│   ├── codeigniter4/
│   │   └── codeigniter4/
│   │       ├── app/
│   │       │   ├── Config/ # Files in here should NOT be loaded.
│   │       ├── composer.json
│   │       ├── system/

[kenjis]

In the current implementation, the priority of the autoloading is:

1. Composer autoloader
2. CI4 autoloader
   1. Classmap loader
   2. PSR-4 autoloader

Composer autoloader has the feature to generate classmap automatically for better performance,
https://getcomposer.org/doc/articles/autoloader-optimization.md#autoloader-optimization
and it is enabled by default in CI4.

CodeIgniter4/admin/starter/composer.json

Line 35 in b6c668c

"optimize-autoloader": true,

This feature works only with namespaces defined in Composer. So it is better to define namespaces in composer.json as much as possible.
