Changes

Script Module Support

• New ScriptModule class
• New ScriptModuleHandler with compatibility checks
• Factory support for creating script modules via AssetFactory
• Dependency extraction plugin support for dependency resolution

Refactoring

• Split Asset interface into core functionality only
• New DataAwareAsset interface for data-related methods (data(), withCondition())
• New FilterAwareAsset interface for filter/attributes methods (filters(), withFilters(), attributes(), withAttributes())
• New traits DataAwareTrait, FilterAwareTrait and DependencyExtractionTrait for DRY implementation
• Updated class hierarchy:
  • Script implements Asset, DataAwareAsset, FilterAwareAsset
  • Style implements Asset, DataAwareAsset, FilterAwareAsset
  • ScriptModule implements only core Asset interface

Limitations

Due to WordPress core limitations, ScriptModule does NOT support:

• Localization
• Inline scripts
• Translations
• Output filters (There's no equivalent to the script_loader_tag filter for Script Modules)

Next Steps

• Add support for the script_module_data_{$module_id} filter for data passing.
• Add Loader support for Script Modules.
