- Implement strict HTTP 200 validation (reject all other status codes)
- Add content-type validation (must be image/*)
- Add 10-second timeout protection with AbortController
- Thread progressCallback through all fetchImageAsBase64 calls
- Add detailed logging for each validation failure scenario
- Report validation failures via SSE progress callbacks
Unit tests:
- Add comprehensive test coverage for all validation scenarios
- Test HTTP status codes (200, 404, 403, 500, etc.)
- Test content-type validation (image/* vs text/html, etc.)
- Test timeout behavior with AbortController
- Test error handling (network errors, DNS, SSL, etc.)
- Test progress callback reporting
Integration tests:
- Add tests for complete extraction flow with URL failures
- Test fallback chain behavior (meta tags → poster → Instagram data → screenshot)
- Test real-world scenarios (redirects, query params, different post types)
Documentation:
- Enhanced JSDoc with validation criteria
- Added examples showing fallback behavior
- Documented all failure scenarios and their handling
All tests passing ✅
