⚡ Bolt: optimize scroll performance and reduce re-renders#7
Conversation
- Implement requestAnimationFrame throttling for scroll events - Use direct DOM manipulation for the scroll progress bar to bypass React reconciliation - Cache heading elements in a ref to avoid redundant querySelectorAll calls - Use a ref to track active heading and minimize state-driven re-renders - Fix unrelated linting errors and ensure clean build Co-authored-by: VagueDustin <127912586+VagueDustin@users.noreply.github.com>

⚡ Bolt Performance Boost
💡 What: Optimized scroll handling by implementing
requestAnimationFramethrottling, direct DOM manipulation for the progress bar, and caching heading elements for the Table of Contents.🎯 Why: High-frequency scroll events were triggering full component re-renders and redundant expensive DOM queries (
querySelectorAll), leading to significant jank during document navigation, especially in large files.📊 Impact:
🔬 Measurement:
Appcomponent no longer re-renders on every scroll tick.querySelectorAllis now called once per content change instead of ~60 times per second during active scrolling.PR created automatically by Jules for task 3224138570231590096 started by @VagueDustin
