- Resolves TypeScript compile errors from iteration 0 review
- All 260 tests passing, build succeeds with no errors
Story 2: Remove SvelteKitPWA Plugin Dependencies
- Remove @vite-pwa/sveltekit from package.json dependencies
- Remove SvelteKitPWA plugin import and configuration from vite.config.ts
- Clean up plugin configuration including manifest, workbox, and devOptions
- Build process now works without plugin (service worker migration needed next)
Dependencies reduced by 309 packages
Build fails on workbox imports as expected - ready for Story 3
Refs: docs/plans/MigrateToNativeSvelteKitPWA.md
✅ All 169 tests passing
✅ Service worker registration working correctly
✅ Push notifications enabled
✅ Test environment properly isolated
Final implementation includes:
- Fixed vite.config.ts configuration for proper service worker registration
- Environment-aware registration (disabled in tests, enabled in dev/prod)
- Documentation and outcome report completed
- Branch ready for merge
Refs: docs/plans/FixServiceWorkerDevRegistrationIssues.md
Complete implementation of fixes for queue processing, SSE connection display, service worker installation, and failing tests.
Key Changes:
- Fix queue processor startup with proper import and subscription mechanism
- Implement centralized API error handling middleware for proper HTTP status codes
- Enhance service worker configuration for PWA compliance and reliability
- Fix SSE connection display with reactive state management
- Add comprehensive test coverage and health check endpoints
Results:
- All 169 tests now passing (previously 16 failing)
- Queue items process immediately from pending to success/error states
- Real-time SSE connection status with auto-reconnection logic
- Proper PWA functionality with working service worker registration
- API endpoints return correct HTTP status codes (400/404/409) instead of 500 errors
This resolves the critical issues preventing core app functionality and enables proper production deployment.
- Fix EventSource is not defined error in queue dashboard
- Add browser guards for all EventSource usage
- Replace static constants (EventSource.OPEN/CLOSED) with numeric values
- Fix setInterval SSR violation in LLM health indicator
- Replace $effect anti-pattern with onMount in share page
- Add comprehensive SvelteKit SSR best practices documentation
- Add SSR audit and testing verification
All changes follow SvelteKit best practices and are verified against
official documentation. Production build succeeds with no SSR errors.
Closes: FixEventSourceSSR
See: docs/outcomes/FixEventSourceSSR.md
- 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 ✅
