objective:
|
|
- Implement JSON export functionality
|
|
- Implement JSON import functionality
|
|
- Implement XML export functionality
|
|
- Implement XML import functionality
|
|
- Handle file operations and errors
|
|
|
|
deliverables:
|
|
- `src/utils/sync.ts` with import/export functions
|
|
- `src/components/ExportDialog.tsx` with export UI
|
|
- `src/components/ImportDialog.tsx` with import UI
|
|
- Error handling components
|
|
|
|
steps:
|
|
- Implement JSON export in `src/utils/sync.ts`:
|
|
- `exportFeedsToJSON(feeds: Feed[]): string`
|
|
- `exportSettingsToJSON(settings: Settings): string`
|
|
- Combine into `exportToJSON(data: SyncData): string`
|
|
- Implement JSON import in `src/utils/sync.ts`:
|
|
- `importFeedsFromJSON(json: string): Feed[]`
|
|
- `importSettingsFromJSON(json: string): Settings`
|
|
- Combine into `importFromJSON(json: string): SyncData`
|
|
- Implement XML export in `src/utils/sync.ts`:
|
|
- `exportToXML(data: SyncDataXML): string`
|
|
- XML serialization
|
|
- Implement XML import in `src/utils/sync.ts`:
|
|
- `importFromXML(xml: string): SyncDataXML`
|
|
- XML parsing
|
|
- Create `src/components/ExportDialog.tsx`:
|
|
- File name input
|
|
- Export format selection
|
|
- Export button
|
|
- Success message
|
|
- Create `src/components/ImportDialog.tsx`:
|
|
- File picker
|
|
- Format detection
|
|
- Import button
|
|
- Error message display
|
|
|
|
tests:
|
|
- Unit: Test JSON import/export with sample data
|
|
- Unit: Test XML import/export with sample data
|
|
- Unit: Test error handling
|
|
- Integration: Test file operations
|
|
|
|
acceptance_criteria:
|
|
- Export creates valid files
|
|
- Import loads data correctly
|
|
- Errors are handled gracefully
|
|
- Files can be opened in text editors
|
|
|
|
validation:
|
|
- Run application and test export/import
|
|
- Open exported files in text editor
|
|
- Test with different data sizes
|
|
- Test error cases (invalid files)
|
|
|
|
notes:
|
|
- Use `FileReader` API for file operations
|
|
- Handle file not found, invalid format, permission errors
|
|
- Add progress indicator for large files
|
|
- Support both JSON and XML formats
|
|
- Ensure data integrity during import
