Key Findings
Architecture & Design
The refactoring successfully extracts file parsing logic into dedicated modules (parser.ts, json.ts), significantly improving code organization and maintainability. The loading spinner integration, while functional, creates direct coupling between file handling and UI state that could be better abstracted.
Security Considerations
IMPORTANT: The drag-and-drop functionality introduces a potential SSRF vulnerability where arbitrary URLs from drag events are fetched without validation. This should be addressed before merge by implementing URL validation or domain whitelisting.
Performance Impact
The changes are generally positive for performance through code consolidation, though there's a minor inefficiency in the eventUtils nested array operations that could be optimized.
Integration Points
The refactoring maintains backward compatibility for the most part, with proper deprecation of old methods. However, the PNG metadata function signature change to explicit typing could potentially break external consumers.
Positive Observations
- Excellent refactoring: Dramatically reduces code duplication by extracting ~200 lines of repetitive file parsing logic
- Improved error handling flow: Centralized error handling through consistent patterns
- Better user experience: Loading spinner provides clear feedback during file processing
- Consistent testing: New eventUtils module includes appropriate unit tests
- Clean separation: File format detection logic properly separated from business logic
Critical Issues to Address
- Security: SSRF vulnerability in URL fetching from drag events (line 24, eventUtils.ts)
- Error handling: Missing try-catch blocks around JSON.parse operations in multiple locations
- State management: Potential spinner state leaks if async operations fail
References
Next Steps
- Address critical security issue before merge - implement URL validation for drag-dropped URIs
- Add comprehensive error handling around JSON parsing operations
- Consider architectural improvements for loading state management
- Add unit tests for the new parser.ts module covering edge cases
This is a comprehensive automated review. For architectural decisions requiring human judgment, please request additional manual review.

Should it indicate the resolution path?

I need to see if anyone else is using this. Things like this should just be module scope unexported functions, or if they have to be on the class, marked as private.
But to answer your question directly: Yes, yes it should.
Summary
Indicate to the user that we're hard at work parsing their JSON behind the scenes.
