How to install modules, for example upgrade_status for D10 compatibility

[pcambra]

Just some notes of what I'm doing for this workflow.

The composer.json file is untouched after dev poser, but if you need additional modules, or upgrade/downgrade the drupal core version, all the stuff ends up in vendor.

This is what my composer.json looks like to install upgrade_status on D9:

{
    "name": "drupal/${WHATEVER_MODULE}",
    "description": "Description text.",
    "type": "drupal-module",
    "license": "GPL-2.0-or-later",
    "repositories": {
        "0": {
            "type": "composer",
            "url": "https://packages.drupal.org/8"
        },
        "drupal": {
            "type": "composer",
            "url": "https://packages.drupal.org/8"
        }
    },
    "require": {
        "drupal/core": "^9",
        "composer/installers": "^1.9",
        "drupal/upgrade_status": "^4.0",
        "drush/drush": "^11.6"
    },
    "minimum-stability": "dev",
    "prefer-stable": true,
    "extra": {
        "installer-paths": {
            "web/core": [
                "type:drupal-core"
            ],
            "web/libraries/{$name}": [
                "type:drupal-library"
            ],
            "web/modules/contrib/{$name}": [
                "type:drupal-module"
            ],
            "web/profiles/contrib/{$name}": [
                "type:drupal-profile"
            ],
            "web/themes/contrib/{$name}": [
                "type:drupal-theme"
            ],
            "drush/Commands/{$name}": [
                "type:drupal-drush"
            ]
        }
    },
    "config": {
        "allow-plugins": {
            "composer/installers": true,
            "dealerdirect/phpcodesniffer-composer-installer": true,
            "cweagans/composer-patches": true,
            "drupal/core-composer-scaffold": true
        }
    },
    "require-dev": {
        "drupal/core-dev": "^9",
        "phpspec/prophecy-phpunit": "^2"
    }
}

The bits require are the composer/installers package together with the extra/installer-paths, and the repositories.

Maybe we could have a way to emulate what poser does with expand composer json (https://git.drupalcode.org/project/gitlab_templates/-/raw/1.0.x/scripts/expand_composer_json.php) to install a module or change the core version?

Note: for upgrade status to work from the UI, had to temporarily remove the symlink_project.php file from the module folder but that's off topic.

If you need additional modules you add them to require-dev and rerun poser. Does that answer your need?

Just giving feedback as I had to try this again and adding a contrib module with require-dev doesn't seem to work, unless I'm missing something, it still adds it in vendor.

This is the composer.json I had to add in the module this time (drupal 10).
