⚡ Bolt: Memoize handleSelectEmail in WorkspaceHome - #519
Conversation
Wrap handleSelectEmail in useCallback in WorkspaceHome.tsx. This prevents the function reference from changing on every render of WorkspaceHome. This is critical because it's passed as the onSelectEmail prop down to EmailListItemComponent which is wrapped in React.memo. By keeping the function reference stable, we allow React.memo to do its job and prevent the entire email list from re-rendering when a user selects a single email or interacts with other parts of the UI.

264-264: ⚡ Quick winConsider keying task update status by task ID.
The
taskUpdateStatusstate is shared across all task rows. If a user rapidly toggles multiple tasks, the confirmation message from the first toggle is overwritten by the second. Per coding guidelines, async state for repeated action rows should be keyed by the row's opaque public ID.Consider using a
Map<string, string>or similar structure keyed bytask.idto maintain per-task feedback independently.🤖 Prompt for AI Agents

💡 What: Wrapped
handleSelectEmailwithuseCallbackinWorkspaceHome.tsx. Added a comment explaining the optimization.🎯 Why:
handleSelectEmailis passed down toEmailListand then toEmailListItemComponent(which is wrapped inReact.memo). WithoutuseCallback,handleSelectEmailis recreated on every render ofWorkspaceHome, causing its reference to change. This forces allEmailListItemComponents to re-render, defeating the purpose ofReact.memo, especially when there are many items in the list.📊 Impact: Significantly reduces React rendering work. When a user clicks an email (or interacts with any state in
WorkspaceHome), only the previously active email and newly active email will re-render, instead of the entire list of 50+ emails.🔬 Measurement: Can be verified using React DevTools Profiler by interacting with the list and observing that the list items no longer re-render unnecessarily.
