Update ChatPage to destructure new functions from useChatSession: ```typescript const { messages, connectionStatus, isTyping, editingMessageId, sendMessage, editMessage, // NEW regenerateMessage, // NEW deleteMessage, // NEW reconnect, } = useChatSession({ conversationId: activeConversationId || "", onError: handleError, initialMessages, }); ``` 2. Pass functions to MessageList as props 3. Update MessageList to forward props to MessageBubble: ```typescript ``` ### Phase 4: Comprehensive Tests ⏳ **Files to Create:** #### 4.1 MessageActionMenu Tests **File:** `apps/web-app/src/components/chat/__tests__/MessageActionMenu.test.tsx` **Test Cases (6 minimum):** 1. Renders menu button 2. Shows edit option for user messages only 3. Shows regenerate option for assistant messages only 4. Does not render for system messages 5. Calls onEdit when edit is clicked 6. Closes menu after action #### 4.2 useChatSession Editing Tests **File:** `apps/web-app/src/hooks/__tests__/useChatSession-editing.test.ts` **Test Cases (4 minimum):** 1. Should edit a message successfully 2. Should delete a message successfully 3. Should regenerate assistant message 4. Should handle edit errors gracefully #### 4.3 MessageBubble Editing Tests **File:** `apps/web-app/src/components/chat/__tests__/MessageBubble-editing.test.tsx` **Test Cases (6 minimum):** 1. Shows edit button on hover for user messages 2. Enters edit mode when edit is clicked 3. Saves edited message when save is clicked 4. Cancels edit when cancel is clicked 5. Saves on Ctrl+Enter keyboard shortcut 6. Cancels on Escape keyboard shortcut ### Phase 5: Polish & Accessibility ⏳ **Tasks:** 1. Add loading states during save operations 2. Add error toast notifications (integrate with toast system) 3. Test keyboard navigation through action menu 4. Test with screen reader (NVDA/JAWS) 5. Verify ARIA attributes are correct 6. Update component documentation with examples 7. Update `FRONTEND_PHASE1_PHASE2_SUMMARY.md` --- ## ⚠️ Known Issues ### Test Environment - ESM Import Issues **Issue:** 4 test suites failing with ESM import errors for `react-syntax-highlighter` **Error:** `require() of ES Module ... refractor@5.0.0 ... not supported` **Affected Tests:** - `src/__tests__/AppSmoke.test.tsx` - `src/__tests__/integration/ChatFlow.test.tsx` - `src/components/chat/__tests__/MessageBubble.test.tsx` - `src/components/chat/__tests__/MessageList.test.tsx` **Additional Failures:** 4 tests in `useChatSession.test.ts` (timeout/mock issues - pre-existing) **Attempted Fixes:** 1. ✅ Added ESM modules to `deps.inline` in vitest.config.mts 2. ✅ Created mock file at `src/__mocks__/react-syntax-highlighter.ts` 3. ✅ Added alias in vitest.config.mts resolve section 4. ❌ Tests still failing (mock not being used correctly) **Root Cause:** `react-syntax-highlighter` imports ESM-only `refractor` package via CommonJS, causing incompatibility in Vitest's test environment. **Impact:** - **Production:** ✅ NO IMPACT - Code works fine in browser - **Development:** ⚠️ 4 test suites cannot run (118/122 passing tests unaffected) - **Phase 1-2:** ✅ Implementations complete and committed (8cf91f0) **Recommendation:** Proceed with Phase 3 (component wiring) since this is a pre-existing test infrastructure issue unrelated to the message editing feature. The failing tests are smoke tests and integration tests that will need to be fixed separately as part of test infrastructure maintenance. **Future Fix Options:** 1. Replace `react-syntax-highlighter` with a different syntax highlighting library 2. Lazy-load syntax highlighter only when needed (code blocks present) 3. Configure Vitest to use Vite's SSR mode for better ESM support 4. Wait for `react-syntax-highlighter` to release CommonJS-compatible version --- ## 📝 Implementation Notes ### API Integration - Edit/delete operations call REST API via apiClient - Regenerate operation uses existing WebSocket streaming - All operations update local state optimistically after server response ### State Management - Editing state managed in MessageBubble component (local) - Message updates flow through useChatSession hook - WebSocket connection maintained throughout editing ### User Experience - Inline editing with textarea (no modal) - Keyboard shortcuts for power users - Confirmation dialog for destructive actions (delete) - Save button disabled during async operations - Original content restored on cancel --- ## 🚀 Next Session Plan 1. **Fix Test Environment** (30 min) - Investigate and resolve ESM import issues - Ensure all existing tests pass - Run `pnpm test` to verify baseline 2. **Phase 3: Wire Up Components** (60 min) - Update ChatPage.tsx - Update MessageList.tsx - Manual testing in browser 3. **Phase 4: Write Tests** (90 min) - MessageActionMenu tests (6 tests) - useChatSession editing tests (4 tests) - MessageBubble editing tests (6 tests) - Run full suite and fix failures 4. **Phase 5: Polish** (45 min) - Loading states and error handling - Accessibility audit - Documentation updates 5. **Final Verification** (30 min) - `make test` (backend) - `pnpm lint` (should pass with warnings only) - `pnpm test` (all tests green) - Manual E2E testing 6. **Commit & Push** (15 min) - Clear commit message - Update CHANGELOG if applicable - Push to origin/main **Estimated Total:** 4-5 hours --- ## 📚 Reference Documents - Full specification: `docs/REMAINING_MESSAGE_EDIT_WORK.md` - Feature specs: `docs/client-implementation/WEB_APP_FEATURE_SPECS.md` - Phase summary: `docs/client-implementation/FRONTEND_PHASE1_PHASE2_SUMMARY.md` --- **Last Updated:** 2025-11-23 **Next Update:** After Phase 3
