Integration Points

1. With Chat System

// In ChatWithThreads component
import { ThreadPanel } from '@/components/chat/ThreadPanel'
import { useThreadStore } from '@/stores/thread-store'

const { activeThreadId, openThread, closeThread } = useThreadStore()

2. With Message Item

// In MessageItem component
import { MessageThreadPreview } from './message-thread-preview'

{message.threadInfo && (
  <MessageThreadPreview
    threadInfo={message.threadInfo}
    onClick={() => onThread?.(message)}
  />
)}

3. With AI System

// In ThreadView component
import { ThreadSummaryPanel } from './ThreadSummaryPanel'

<ThreadSummaryPanel
  messages={componentMessages}
  threadId={threadId}
  autoGenerate={false}
/>

  notifications_enabled BOOLEAN DEFAULT TRUE,
  UNIQUE(thread_id, user_id)
);

-- Add thread_id to messages
ALTER TABLE nchat_messages
  ADD COLUMN thread_id UUID REFERENCES nchat_threads(id) ON DELETE CASCADE;

Indexes

CREATE INDEX idx_threads_channel_id ON nchat_threads(channel_id);
CREATE INDEX idx_threads_parent_message_id ON nchat_threads(parent_message_id);
CREATE INDEX idx_thread_participants_user_id ON nchat_thread_participants(user_id);
CREATE INDEX idx_thread_participants_thread_id ON nchat_thread_participants(thread_id);
CREATE INDEX idx_messages_thread_id ON nchat_messages(thread_id);

Usage Examples

1. Opening a Thread

import { useThreadStore } from '@/stores/thread-store'

function MessageActions({ message }) {
  const { openThread } = useThreadStore()

  const handleStartThread = () => {
    openThread(message.id)
  }

  return (
    <Button onClick={handleStartThread}>
      Start Thread
    </Button>
  )
}

2. Listing User's Threads

import { useThreads } from '@/hooks/use-threads'

function MyThreads() {
  const { threads, unreadCount, loading } = useThreads({
    userId: user?.id,
    limit: 20,
  })

  return (
    <div>
      <h2>My Threads ({unreadCount} unread)</h2>
      {threads.map(thread => (
        <ThreadItem key={thread.id} thread={thread} />
      ))}
    </div>
  )
}

3. Thread Activity Feed

import { useThreadActivity } from '@/hooks/use-threads'

function ThreadActivityFeed() {
  const { activityItems, loading, loadMore, hasMore } = useThreadActivity({
    limit: 50,
  })

  return (
    <div>
      {activityItems.map(item => (
        <ActivityItem key={item.id} item={item} />
      ))}
      {hasMore && <Button onClick={loadMore}>Load More</Button>}
    </div>
  )
}

4. Creating a Thread

import { useThreads } from '@/hooks/use-threads'

function CreateThreadButton({ messageId, channelId }) {
  const { createThread } = useThreads({ channelId })

  const handleCreate = async () => {
    const thread = await createThread(
      messageId,
      "Starting a thread about this..."
    )
    if (thread) {
      // Thread created successfully
    }
  }

  return <Button onClick={handleCreate}>Reply in Thread</Button>
}

Testing

Component Tests

# Run existing tests
pnpm test src/components/thread/__tests__/

# Files with tests:
- thread-preview.test.tsx
- thread-panel.test.tsx
- thread-sidebar.test.tsx

Integration Tests

The system is designed to work seamlessly with:

✅ Chat message list
✅ Channel sidebar
✅ Real-time subscriptions
✅ Message actions
✅ User presence
✅ Notifications

Performance Considerations

Pagination: All lists use cursor-based pagination
Caching: Apollo cache prevents redundant fetches
Subscriptions: Only active threads subscribe to updates
Optimistic Updates: Instant UI feedback
Lazy Loading: Components load only when needed
Memoization: Expensive computations are memoized

Next Steps (Optional Enhancements)

While the system is feature-complete, here are optional enhancements:

Thread Templates - Pre-defined thread structures
Thread Analytics - Track engagement metrics
Thread Recommendations - Suggest relevant threads
Thread Pinning - Pin important threads
Thread Emoji Reactions - React to entire threads
Thread Bookmarking - Save threads for later
Thread Export - Export thread as PDF/HTML
Thread Permissions - Fine-grained access control
