  • Effects for polling, auto-scroll, prompt handling
  • Workflow operations (send messages, start workflows)
  • Event handlers
• Size: ~196 lines

MessageList.tsx (Message Display)

• Purpose: Handles the display of all messages and status indicators
• Responsibilities:
  • Renders loading and error states
  • Maps through messages using MessageItem
  • Includes WorkflowStatusDisplay
  • Handles auto-scroll reference

  • Shared type definitions
• Size: ~50 lines

Benefits of This Structure

1. Separation of Concerns: Each file has a single, clear responsibility
2. Reusability: Components can be easily reused or tested independently
3. Maintainability: Easier to locate and modify specific functionality
4. Readability: Smaller files are easier to understand and navigate
5. Testing: Individual components can be unit tested in isolation
6. Type Safety: Centralized types ensure consistency across components

Usage

Import the main component as before:

import DashboardChatArea from './DashboardChatArea';
// or
import DashboardChatArea, { DashboardChatAreaProps } from './DashboardChatArea';

The API remains exactly the same - this refactoring is purely internal and doesn't affect how the component is used by parent components.

Development Guidelines

• Adding new features: Consider which component/file is most appropriate
• State changes: Most state logic should go in useChatLogic.ts
• UI changes: Modify the relevant component file
• New types: Add to types.ts
• Styling: All styles remain in DashboardChatArea.module.css
