⚡ Bolt: [performance improvement] Memoize IconifyIcon lookup#40sshahriazz wants to merge 1 commit into
Conversation
- Introduced a simple `Map` cache inside `IconifyIcon.tsx` to memoize the results of `iconData(icon)`. - This prevents redundant O(N) JSON tree iterations and `getIconData` calls during React re-renders. - Recorded critical learning regarding `IconifyIcon` performance into `.jules/bolt.md`.

💡 What: Added a module-level
Mapcache to memoize theiconDataresolution inclient/src/components/base/IconifyIcon.tsx.🎯 Why: The custom
IconifyIconcomponent used an O(N) iteration over multiple large@iconify-jsonstatic icon sets to support offline prefix-less icon lookups. Because this resolution happened synchronously on every render and the leaf component is heavily used across the application (>190 times), it represented a significant, codebase-specific render bottleneck.📊 Impact: Reduces redundant O(N) object iterations to O(1) map lookups, speeding up React re-renders anywhere icons are used heavily (such as lists or navbars).
🔬 Measurement: Verify by using React Profiler in Next.js development tools. Rendering a large list of
IconifyIconcomponents will show significantly shorter execution times for theIconifyIconnode tree.PR created automatically by Jules for task 2437376435019568046 started by @sshahriazz
