How to upload packages to different directories depending on Type?

Question

Composer

I make a "module manager", each module is a separate composer package, in its composer.json: How to change the download directory for this type? So that packages with type "my-package-type" are loaded not in vendor, but in modules for example ? I need it to display a list of all available modules, that is, roughly speaking: Everything in the "modules" folder is modules, and I can work with them. Solution 2: How to find (without enumeration and checking the type - of each package) in the vendor directory all packages with my type ?
"type": "my-package-type"

Answer 1

In general, we clone Composer / Installers and rewrite Installer as needed.
