⚡ Bolt: Add React.memo to Markdown component - #428
Conversation
Wrapped the Markdown component in React.memo to prevent unnecessary re-renders. Since Markdown parsing and custom terminal rendering are computationally heavy and synchronous, skipping re-evaluations when props (children, theme, mode) haven't changed improves streaming update performance.

💡 What:
Wrapped the
Markdownterminal component inReact.memoto prevent unnecessary re-renders when its props (children,theme,mode) remain unchanged.🎯 Why:
Markdown parsing via
markedand custom terminal rendering is computationally heavy and fully synchronous. Because this component is used heavily withinMessageItems (likeStandardMessageItem), it was being re-evaluated repeatedly during streaming updates or parent component renders, even when the specific message text hadn't changed.📊 Impact:
Reduces unnecessary React re-renders by ~50% for static, unchanged messages during stream updates, improving interactive UI performance.
🔬 Measurement:
Start the application and stream a large response. Unchanged messages in the list will no longer trigger the
