Component Structure

When generating React/TSX components, follow these structural points to maintain information focus under Primacy/Recency:

1. •Decompose logically related UI modules into independent sub-components, ensuring each handles a single responsibility.
2. •Declare all sub-components as const before the main component, making dependency order clear at a glance.
3. •Keep each sub-component within 30-40 lines, continue decomposing to finer granularity if needed.
4. •Use semantic naming (e.g., VideoOverlay, ActionButton, CreatorInfo) for quick retrieval and reuse.
5. •Use Props to clarify data and event flow, let main component only handle assembly and state dispatch.
6. •Regularly review if sub-components can be extracted to shared directory to avoid duplicate implementations.

Reference example:

// Sub-components defined first
const PlayOverlay = ({ isPlaying, onToggle }: PlayOverlayProps) => (
  <div className="...">...</div>
)

const ActionButtons = ({ likes, comments }: ActionButtonsProps) => (
  <div className="...">...</div>
)

// Main component uses sub-components
export function VideoFeed({ videos }: VideoFeedProps) {
  return (
    <div>
      {videos.map(v => (
        <PlayOverlay ... />
        <ActionButtons ... />
      ))}
    </div>
  )
}

Final confirmation: Main component handles orchestration, sub-components handle details, achieving a stable pipeline of "decompose first, then compose".
