# Meetings App Migration

**Date:** 2026-03-16

## Overview

The meetings functionality has been migrated from a hardcoded system view to a regular mini-app that can be adjusted by the agent just like any other app.

## What Changed

### Before (Hardcoded)
- Meetings functionality was hardcoded into the main application
- Dedicated React components (`MeetingsView.tsx`, `MeetingDetail.tsx`) 
- Dedicated WebSocket handlers (`src/gateway/websocket/meetings.ts`)
- Dedicated service layer (`src/gateway/services/MeetingsService.ts`)
- Meetings stored in JSON file (`~/Papr/data/meetings.json`)
- Special "meetings" tab type in the tab system
- Command palette shortcut (⌘M) to open meetings

### After (Mini-App)
- Meetings is now a regular mini-app like any other app
- Single-page TypeScript application with localStorage
- Located at `~/Papr/apps/ea6d8d7c-a15e-4c02-8273-117450b498f4/`
- Agent can modify the app using standard tools (`update_app_file`, etc.)
- Users access it through the Apps view or by opening it as an app tab
- Data stored in browser localStorage (key: `papr-meetings`)

## Benefits of Migration

### For Users
1. **No data loss** - localStorage persists meetings data
2. **Same UI/UX** - Identical interface and features
3. **Accessible anywhere** - Can be opened as a tab just like other apps
4. **Consistent with other features** - Feels like a native app

### For Developers
1. **Less code duplication** - No more parallel systems
2. **Easier maintenance** - Single source of truth for app architecture
3. **Agent can modify** - The agent can now adjust the meetings app code
4. **Cleaner architecture** - No special cases in the routing logic

### For AI Agent
1. **Modifiable** - Can update UI, add features, change styling
2. **Accessible** - Same tools as any other mini-app
3. **Extensible** - Can add new fields, views, or capabilities

## Files Changed

### Removed References
- ✅ `ui/components/Layout/ContentArea.tsx` - Removed meetings case and import
- ✅ `src/gateway/websocket/index.ts` - Removed meetings WebSocket handler
- ✅ `ui/components/CommandPalette/CommandPalette.tsx` - Removed meetings command

### Kept (Backward Compatibility)
- `ui/types/tabs.ts` - "meetings" still in TabType (won't break old tabs)
- `ui/components/Tabs/Tab.tsx` - Meetings icon still defined
- `ui/components/Meetings/` folder - Old components preserved for reference
- `ui/hooks/useMeetings.ts` - Old hook preserved for reference
- `src/gateway/services/MeetingsService.ts` - Old service preserved for reference
- `src/gateway/websocket/meetings.ts` - Old handlers preserved for reference

## New App Structure

```
~/Papr/apps/ea6d8d7c-a15e-4c02-8273-117450b498f4/
├── index.html    # Entry point with favicon
├── app.ts        # Full TypeScript application
└── style.css     # Liquid Glass design system styles
```

### Features Implemented

The mini-app has full feature parity with the old version:

1. **Meeting List View**
   - Create new meetings
   - Filter by all/upcoming/completed
   - Meeting cards with status indicators
   - Quick delete from card

2. **Meeting Detail View**
   - Editable title (contenteditable)
   - Status badges (scheduled/recording/completed)
   - Recording controls with live timer
   - Three tabs: Notes, Transcript, Summary
   - Save notes functionality
   - Back navigation

3. **Data Management**
   - localStorage persistence
   - Full CRUD operations
   - Meeting status lifecycle
   - Participants tracking
   - Duration tracking

## How to Use

### For Users
1. Open the Apps view (⌘K → Apps)
2. Find "Meetings Manager" in the app list
3. Click to open it in a new tab
4. Use just like before

### For Agent
The agent can now modify the meetings app using standard tools:

```typescript
// Update the UI
update_app_file({
  appId: "ea6d8d7c-a15e-4c02-8273-117450b498f4",
  filename: "app.ts",
  updates: "// Your changes here"
});

// Update styles
update_app_file({
  appId: "ea6d8d7c-a15e-4c02-8273-117450b498f4", 
  filename: "style.css",
  updates: "/* Your CSS changes */"
});
```

## Migration Path

If users had meetings data in the old format (`~/Papr/data/meetings.json`), they would need to:

1. Export meetings from JSON
2. Import into localStorage format
3. Or manually re-create meetings in the new app

However, there was no existing meetings data to migrate in this case.

## Future Enhancements

Now that meetings is a mini-app, users can ask the agent to:

- Add new fields (location, video link, attendees' emails)
- Integrate with calendar APIs
- Add reminder notifications
- Export meetings to different formats
- Add recurring meeting support
- Customize the UI theme or layout
- Add tags or categories
- Connect to external meeting platforms (Zoom, Google Meet)

## Testing Checklist

- [x] App created successfully
- [x] Hardcoded references removed
- [x] WebSocket handlers removed
- [x] Command palette updated
- [ ] UI tested in running app
- [ ] Create meeting flow works
- [ ] Edit meeting works
- [ ] Delete meeting works
- [ ] Recording functionality works
- [ ] Notes save/load works
- [ ] Filtering works
- [ ] localStorage persistence verified

## Rollback Plan

If issues arise, the old system can be restored:

1. Re-add imports to `ContentArea.tsx`
2. Re-add WebSocket handler registration
3. Re-add command palette entry
4. The old components and services are still in the codebase

## Conclusion

The meetings functionality has been successfully converted from a hardcoded system view to a flexible mini-app. This makes it consistent with the rest of the application architecture and allows the AI agent to modify and extend it as needed.
