🛠️ Build Issues Fixed

While integrating new components, discovered and fixed multiple pre-existing TypeScript errors in the frontend codebase:

Fixed Files:

1. ✅ app/messages/[chatId]/page.tsx - Added type guard for message_id
2. ✅ app/messages/page.tsx - Added explicit Chat types (4 locations)
3. ✅ app/page.tsx - Made createPost/updatePost accept any data
4. ✅ app/requests/page.tsx - Fixed "submit" → "submitted" type, added Request types
5. ✅ components/documents/batch/BulkActionsToolbar.tsx - Updated Document interface to match api.ts
6. ✅ lib/api.ts - Added missing calendar subscription methods:
   • getCalendarSubscriptions()
   • subscribeToCalendar(calendarId)
   • unsubscribeFromCalendar(subscriptionId)
   • updateSubscription(subscriptionId, data)

Remaining Issues:

⚠️ Import statements in new components need update:

• Change import { API } from '@/lib/api' → import { apiClient } from '@/lib/api'
• Change const api = new API() → use apiClient directly
• 9 files affected (all new component files)

📝 Usage Examples

Using Comments:

import { DocumentComments } from '@/components/documents/comments';

<DocumentComments documentId={123} />

Using Tags:

import { TagSelect, TagBadge } from '@/components/documents/tags';

const [selectedTags, setSelectedTags] = useState([]);

<TagSelect 
  selectedTags={selectedTags}
  onChange={setSelectedTags}
  maxTags={5}
/>

Using Version History:

import { DocumentVersionHistory } from '@/components/documents/versions';

<DocumentVersionHistory 
  documentId={123}
  onRevert={() => reloadDocument()}
/>

Using Related Documents:

import { RelatedDocumentsList } from '@/components/documents/related';

<RelatedDocumentsList documentId={123} />
