33-33: Hover-based prefetch delay
DefiningHOVER_DELAYis a clear way to manage prefetch timing. You could consider making this configurable if user feedback varies.
246-252:scrollRefandhandleScrolllogic
Your condition checks prevent redundant loading, which is excellent. Consider removing or replacing theconsole.logwith a more robust logging mechanism for production.- console.log('Loading more items...'); + // console.debug('Loading more items...');
265-265: Commented-out toast call
Leaving commented-out code may lead to confusion. Either remove or add a clarifying comment if it's intended for future use.
533-548:rowRenderercallback
UsinguseCallbackis optimal for rerender performance. Defining a proper type instead of@ts-expect-errorwould solidify type safety.- // @ts-expect-error (props) => ( + (props: { index: number; data: InitialThread }) => (

100-100: Added "react-virtuoso" dependency
This addition aligns perfectly with the goal of leveraging efficient list virtualization.apps/mail/components/mail/mail-list.tsx (9)
12-13: Refined import statements
Consolidating type imports from '@/types' and including icon imports from 'lucide-react' is well-organized.
20-21: Utilization ofnext-intlandScrollArea
AdoptinguseFormatterfromnext-intland the customScrollAreacomponent is a good approach for i18n and structured scrolling.
23-23: Type import fromreact-virtuoso
ImportingVirtuosoHandlehelps maintain reliable typings for controlling the virtualized list.
29-29: IntroducingVirtuoso
Migrating to thereact-virtuosolibrary is a key part of improving scrolling performance.
131-201: RefactoredThreadcomponent structure
Wrapping content in<div className="p-1">and separating event handlers on a nested<div>provides a more readable layout. Keep an eye on accessibility for any clickable container elements.
221-221: Memoization ofMailList
EncapsulatingMailListwithmemocan reduce unnecessary re-renders and improve overall performance.
333-333: New hotkey for marking unread
Double-check for any conflicts with other system/app shortcuts—otherwise, this is a useful addition.
421-450: Global key state management
Attaching and removing key and window blur event listeners is done correctly, including cleanup. This approach effectively handles multi-select mode toggling.
550-573: ImplementingVirtuosoin the render flow
This integration neatly handles large lists with infinite scrolling. The code looks clean, and the virtualization logic should be significantly more efficient.

119-123: Remove console.log statement before deployment.There's a debug console.log statement that should be removed before deploying to production.
const handleScroll = useCallback(() => { if (isLoading || isValidating || !nextPageToken) return; - console.log('Loading more items...'); void loadMore(); }, [isLoading, isValidating, loadMore, nextPageToken]);
361-374: Fix type issue in rowRenderer function.The rowRenderer function has a TODO comment and a ts-expect-error annotation that should be addressed for proper type safety.
You can fix the typing issue by properly defining the type for the props parameter:
const rowRenderer = useCallback( - //TODO: Add proper typing - // @ts-expect-error - (props) => ( + (props: { index: number; data: InitialThread }) => ( <Draft onClick={handleMailClick} selectMode={selectMode} isCompact={isCompact} message={props.data} {...props} /> ), [handleMailClick, selectMode, isCompact], );
48-97: Consider memoizing the Draft component for better performance.The Draft component is being rendered for potentially many items in the virtualized list. Memoizing it could prevent unnecessary re-renders and further improve performance.
-const Draft = ({ message, onClick }: ThreadProps) => { +const Draft = React.memo(({ message, onClick }: ThreadProps) => { const [mail] = useMail(); const [searchValue] = useSearchValue(); const isMailSelected = message.id === mail.selected; const isMailBulkSelected = mail.bulkSelected.includes(message.id); return ( <div className="p-1"> {/* component content */} </div> ); -}; +});

3-3: Good decision to remove the async keyword.Since this component is only rendering another component and not performing any asynchronous operations, removing the
asynckeyword is appropriate and aligns with React best practices.apps/mail/components/draft/drafts-list.tsx (4)
6-6: Good addition of react-virtuoso.Adding the Virtuoso component from react-virtuoso is a good choice for performance optimization when rendering large lists.
117-117: Correct typing update for scrollRef.Updating the ref type from HTMLDivElement to VirtuosoHandle is necessary for properly interacting with the Virtuoso component's API.
379-387: Good implementation of the Virtuoso component.The Virtuoso component is correctly set up with the appropriate props for virtualized rendering. This will significantly improve performance when rendering large lists of drafts.
389-397: Good loading indicator implementation.The loading indicator is well implemented, showing a spinner when more items are being loaded and a placeholder div when not loading.
