Greptile Summary

Based on the provided files and changes, here's a concise summary of the CSF factories pull request:

Introduces CSF (Component Story Format) factories to provide a more structured and type-safe way to define Storybook configurations and stories.

  • Added defineConfig and meta.story() pattern for type-safe story definitions in /code/renderers/react/src/preview.tsx
  • Modified processCSFFile to detect and handle CSF4 factory format via isCSFFactoryPreview flag
  • Added support for per-CSF-file project annotations that can override global settings
  • Updated test infrastructure to support factory pattern in Vitest transformer and portable stories
  • Added comprehensive test coverage for both traditional CSF and new factory approaches

The changes provide better type safety and structure while maintaining backward compatibility with existing CSF formats. The implementation appears solid but requires careful testing around project annotation overrides and factory pattern adoption.

logic: Object.values() and find() could return undefined. Need type checking and error handling for when no CSF factory preview is found.

logic: preview is used in composeConfigs even when csfFactoryPreview is found, which could cause conflicts. Should only include preview in non-factory case.

logic: The meta method accepts any for TRenderer annotations but then casts to TMetaArgs. This could lead to type safety issues. Consider constraining the any type.
