- Replace Semi UI's MarkdownRender with react-markdown library for better performance and features
- Add comprehensive markdown rendering support including:
* Math formulas with KaTeX
* Code syntax highlighting with rehype-highlight
* Mermaid diagrams support
* GitHub Flavored Markdown (tables, task lists, etc.)
* HTML preview for code blocks
* Media file support (audio/video)
- Create new MarkdownRenderer component with enhanced features:
* Copy code button with hover effects
* Code folding for long code blocks
* Responsive design for mobile devices
- Add white text styling for user messages to improve readability on blue backgrounds
- Update all components using markdown rendering:
* MessageContent.js - playground chat messages
* About/index.js - about page content
* Home/index.js - home page content
* NoticeModal.js - system notice modal
* OtherSetting.js - settings page
- Install new dependencies: react-markdown, remark-math, remark-breaks, remark-gfm,
rehype-katex, rehype-highlight, katex, mermaid, use-debounce, clsx
- Add comprehensive CSS styles in markdown.css for better theming and user experience
- Remove unused imports and optimize component imports
Breaking changes: None - maintains backward compatibility with existing markdown content
Previously, the "thinking" indicator and loading icon would only disappear
after the entire message generation was complete, which created a poor user
experience where users had to wait for the full response to see that the
reasoning phase had finished.
Changes made:
- Add `isThinkingComplete` field to independently track reasoning state
- Update streaming logic to mark thinking complete when content starts flowing
- Detect closed `<think>` tags to mark reasoning completion
- Modify MessageContent component to use independent thinking state
- Update "思考中..." text and loading icon display conditions
- Ensure thinking state is properly set in all completion scenarios
(non-stream, errors, manual stop)
Now the thinking section immediately shows as complete when reasoning ends,
rather than waiting for the entire message to finish, providing much better
real-time feedback to users.
Files modified:
- web/src/hooks/useApiRequest.js
- web/src/components/playground/MessageContent.js
- web/src/utils/messageUtils.js
Completely restructured the Playground component from a 1437-line monolith
into a maintainable, modular architecture with 62.4% code reduction (540 lines).
**Key Improvements:**
- **Modular Architecture**: Extracted business logic into separate utility files
- `utils/constants.js` - Centralized constant management
- `utils/messageUtils.js` - Message processing utilities
- `utils/apiUtils.js` - API-related helper functions
- **Custom Hooks**: Created specialized hooks for better state management
- `usePlaygroundState.js` - Centralized state management
- `useMessageActions.js` - Message operation handlers
- `useApiRequest.js` - API request management
- **Code Quality**: Applied SOLID principles and functional programming patterns
- **Performance**: Optimized re-renders with useCallback and proper dependency arrays
- **Maintainability**: Implemented single responsibility principle and separation of concerns
**Technical Achievements:**
- Eliminated code duplication and redundancy
- Replaced magic strings with typed constants
- Extracted complex inline logic into pure functions
- Improved error handling and API response processing
- Enhanced code readability and testability
**Breaking Changes:** None - All existing functionality preserved
This refactor transforms the codebase into enterprise-grade quality following
React best practices and modern development standards.
- Add role toggle button in MessageActions component for assistant/system messages
- Implement handleRoleToggle function in Playground component to switch between assistant and system roles
- Add visual distinction for system messages with orange badge indicator
- Update roleInfo configuration to use consistent avatars for assistant and system roles
- Add proper tooltip texts and visual feedback for role switching
- Ensure role toggle is disabled during message generation to prevent conflicts
This feature allows users to easily switch message roles between assistant and system,
providing better control over conversation flow and message categorization in the playground interface.
Fix TypeError when processing multimodal messages containing both text and images.
The error "textContent.text.trim is not a function" occurred when textContent
was null or textContent.text was not a string type.
Changes:
- Add comprehensive type checking for textContent.text access
- Implement getTextContent() utility function for unified content extraction
- Enhance error handling to support multimodal content display
- Fix message copy functionality to handle array-format content
- Improve message reset functionality to extract text content for retry
- Add user-friendly warnings when copying messages without text content
Technical improvements:
- Validate textContent existence and text property type before calling trim()
- Extract text content from multimodal messages for operations like copy/retry
- Maintain backward compatibility with string-format content
- Preserve all existing functionality while adding robust error handling
Fixes issues with:
- Image + text message processing
- Message copying from multimodal content
- Message retry with image attachments
- Error display for complex message formats
This ensures the playground component handles multimodal content gracefully
without breaking existing text-only message functionality.
