    }
}

Autoload

After handling all magento components, file app/etc/vendor_path.php with path to vendor directory is created inside application directory.

This information allows the application to utilize Composer autoloader in case any libraries are installed in vendor directory. The path to vendor varies between particular installations and depends on magento-root-dir setting for the Magento Composer Installer. That's why it should be generated for each installation.

After composer install/update is done the application is ready to work.

Deployment Strategy

The default deployment strategy used by Magneto Composer Installer is copy. It will copy each files/directories from vendor directory to its designated location based on extra/map information stored in each component composer.json file.

There are other deployment strategy that could be used, however Magento 2.x system does not guarantee its successful operation.
