Description

This PR transforms the CodeIndexPopover component from a basic settings form into a robust, user-friendly configuration interface with comprehensive validation and state management.

Key Implementation Details:

• Zod Validation Schema: Implemented provider-specific validation schemas that adapt based on the selected embedding provider (OpenAI, Ollama, OpenAI-compatible, Gemini)
• Real-time Error Feedback: Added visual error indicators (red borders) and inline error messages that appear immediately when validation fails
• Unsaved Changes Protection: Implemented change detection with a confirmation dialog to prevent accidental data loss
• Internationalization: All validation messages now use i18n keys for proper localization support
• State Management: Added comprehensive form state tracking for errors, unsaved changes, and dialog states

Design Choices:

• Used Zod for validation to ensure type safety and consistent error handling
• Implemented partial schema validation to handle secret fields with placeholder values
• Added error clearing on user input for better UX
• Used VSCode theme colors for consistent error styling

Areas for Review Focus:

• Validation logic for different embedding providers
• Unsaved changes detection and dialog flow
• Error message internationalization implementation
• Form state management and error clearing behavior

Test Procedure

Unit Tests:

• Created comprehensive test suite: CodeIndexPopover.validation.spec.tsx
• Tests cover all embedding providers (OpenAI, Ollama, OpenAI-compatible, Gemini)
• Validates both Zod schema validation and manual validation logic
• Tests internationalization by checking for i18n keys in error messages

Manual Testing Steps:

1. Open CodeIndexPopover component
2. Try different embedding providers and test validation:
   • Leave required fields empty and attempt to save
   • Enter invalid URLs and verify error messages
   • Test with valid data to ensure validation passes
3. Test unsaved changes dialog:
   • Make changes to form fields
   • Attempt to close popover without saving
   • Verify confirmation dialog appears
4. Test error clearing:
   • Trigger validation errors
   • Start typing in error fields
   • Verify errors clear on user input

Testing Environment:

• Run tests: cd webview-ui && npx vitest src/components/chat/__tests__/CodeIndexPopover.validation.spec.tsx
• All 6 validation tests should pass
• Manual testing in VSCode extension environment

Pre-Submission Checklist

Screenshots / Videos

Before: Basic form with no validation feedback
After: Enhanced form with:

• Red border indicators on invalid fields
• Inline error messages below each field
• Confirmation dialog for unsaved changes
• Proper error clearing on user input

Screenshots would be helpful here to show the visual improvements, but are not included in this text-based response.

Documentation Updates

• No documentation updates are required.

Additional Notes

Translation Support:

• Added 10 new validation message keys to webview-ui/src/i18n/locales/en/settings.json
• All validation errors now use i18n keys for proper localization
• English translations provided; other language files will need updates

Performance Considerations:

• Validation only runs on save attempt, not on every keystroke
• Error clearing is optimized to only update specific field errors
• Dialog state management uses React hooks for efficient re-renders

Future Enhancements:

• Could add real-time validation (on blur/change) if desired
• Could extend validation to include more complex rules
• Could add success states and animations
