Site Studio Sync includes a source type of default_module_package. This type is handled by the modules/cohesion_sync/src/Services/DefaultModulePackage.php service. Package source type services are gathered by PackageSourceManager service collector using sitestudio_package_source tag. It is possible to add your own custom types that would handle default packages in a different manner, for example fetching package stored in a remote FTP or AWS S3 bucket. To do so, you would need to follow these steps:
- Write your own package source service that Implements
Drupal\cohesion_sync\Services\PackageSourceServiceInterface interface.
- Register your service using
sitestudio_package_source tag and appropriate priority, depending if you are registering a new source type or overriding an existing one.
- Define your
site_studio.packages.yml containing your new (or overridden) type and relevant metadata in source property.
