⚡ Bolt: Memoize AppBackground to prevent unnecessary re-renders#66alazndy wants to merge 1 commit into
Conversation
During frequent global state updates (like drag-and-drop or modal interactions in App.tsx), the relatively static AppBackground component was being forced to re-render. Wrapping it in React.memo prevents these expensive rendering cycles, freeing up CPU overhead for smoother interactive performance. Co-authored-by: alazndy <78882672+alazndy@users.noreply.github.com>

💡 What
Wrapped the
AppBackgroundcomponent inReact.memoand assigned adisplayNameto preserve DevTools visibility.🎯 Why
The top-level
Appcomponent holds almost all global UI state. When dragging widgets around or opening/closing modals,Appre-renders frequently. BecauseAppBackgroundis a child ofAppand is visually large (covering the screen, sometimes containing animated orbs), allowing it to re-render on every drag coordinate change or modal toggle wastes significant CPU cycles calculating unchanged DOM structures.📊 Impact
Prevents 100% of unnecessary
AppBackgroundcomponent re-renders during state changes that do not modify background configuration (e.g., interacting with widgets, lists, or dragging layout blocks). This directly improves the perceived framerate and smoothness of dragging operations and modal transitions, particularly on lower-end devices.🔬 Measurement
Run
pnpm run buildandpnpm run build:storeto verify the code correctly packages. Use React Profiler while dragging a widget around the screen on a slow CPU profile; you will observe the "AppBackground" node bypassing the render phase in the commit chart.PR created automatically by Jules for task 14208354021272981217 started by @alazndy
