Implement streaming text parser for AI responses
Feature Request
Build a streaming text parser that handles incremental rendering of AI responses with markdown formatting.
Requirements
Real-Time Rendering
- Parse markdown chunks as they arrive
- Update DOM incrementally without flickering
- Handle incomplete markdown (mid-word, mid-tag)
- Buffer incomplete tokens
Markdown Support
- Code blocks with syntax highlighting (Prism.js)
- Inline code, bold, italic
- Lists (ordered, unordered)
- Links and images
- Tables
- Blockquotes
Performance
- Handle 1000+ words/second streaming rate
- Use Web Workers for heavy parsing
- Debounce DOM updates (every 50ms)
- Memory efficient (< 10MB for 100K words)
Edge Cases
- Malformed markdown
- Very long responses (> 10K words)
- Connection interruptions
- Rate limiting backpressure
Security Considerations
-
⚠️ Must sanitize markdown to prevent XSS - Related to web-app-react#1 (XSS vulnerability)
- Use DOMPurify for sanitization
