# Plan: Combined P2P Polling App
## Overview
Merge the three subfolder projects into a single TypeScript + Yjs + Vite application at the repo root, combining the best features from each.
## Technology Choices
- **Language:** TypeScript (from project 3) with strict mode
- **CRDT:** Yjs + y-webrtc + y-indexeddb (from projects 1 & 3)
- **Build:** Vite (shared by all)
- **Package manager:** npm
## Feature Superset
From **project 1** (group-efa16e66):
- Collaborative title editing via Y.Text (real-time character-level sync)
- Delete options
- Diff-rendering for poll list (reuse DOM elements)
- Peer count display via awareness
- Share section with copy-to-clipboard
From **project 2** (proposal-8835ffc9):
- Deadline/timer system (2-minute voting window with countdown)
- Duplicate detection (case-insensitive)
From **project 3** (proposal-88461784):
- TypeScript types & strict mode
- Modular architecture (state, sync, render, identity, app layers)
- IndexedDB persistence (offline support)
- Online/offline connection tracking
- Input validation (max lengths, empty checks)
- HTML escaping for XSS prevention
- ViewModel pattern for clean render layer
## Data Model (Yjs)
```
Y.Doc
├── poll-meta (Y.Map<string>)
│ └── title → Y.Text (collaborative editing from project 1)
├── poll-options (Y.Map<OptionRecord>)
│ └── [optionId] → { id, label, createdAt, createdBy }
├── poll-votes (Y.Map<string>)
│ └── [userId] → optionId (single vote per user)
└── poll-deadline (Y.Map<any>)
└── deadline → number | null (timestamp, from project 2)
```
## Architecture & File Structure

│ └── styles.css (merged: project 1's design tokens + project 3's glassmorphism)
```
## Implementation Steps
### Step 1: Scaffold root project
- Create `package.json` with dependencies: yjs, y-webrtc, y-indexeddb, vite, typescript
- Create `tsconfig.json` (strict, ES2022, bundler resolution)
- Create `index.html` entry point
- Create `vite.config.ts` if needed
### Step 2: Core layer — identity.ts, state.ts, sync.ts
- `identity.ts`: port from project 3 (getUserId)
- `state.ts`: port types from project 3, add deadline types, add ViewModel with deadline/timer info, add vote percentage calculation from project 1
- `sync.ts`: port from project 3, add Y.Text for title (from project 1), add poll-deadline map, add awareness tracking for peer count (from project 1)
### Step 3: App orchestrator — app.ts, main.ts
- `app.ts`: port from project 3, add deadline handlers, add delete option handler, wire up all components
- `main.ts`: minimal entry that calls initApp
### Step 4: Components
- `PollTitle.ts`: port collaborative Y.Text editing from project 1, add TypeScript types
- `AddOption.ts`: merge project 1 (UI/animation) + project 2 (duplicate detection) + project 3 (validation)
- `PollOption.ts`: port from project 1 (vote bar, percentage, delete button), add TypeScript
- `PollList.ts`: port diff-rendering from project 1, add TypeScript
- `StatusBar.ts`: merge project 1 (peer count) + project 3 (online/offline status)
- `ShareSection.ts`: port from project 1, add TypeScript
- `DeadlineTimer.ts`: new component porting project 2's deadline/countdown logic to Yjs
### Step 5: Styling
- Merge CSS: use project 1's design tokens and typography as base, incorporate project 3's glassmorphism panel effects, add timer-specific styles from project 2
### Step 6: Cleanup
- Remove three subfolders (after confirming with user)
- Update root README.md

# P2P Poll App # P2P Poll App
A peer-to-peer polling application where users can create polls, add options, and vote in real-time without a central server.
## Features
- **Real-time P2P voting** using WebRTC via PeerJS
- **Dynamic option management** - add/remove options during polling
- **Duplicate vote prevention** - one vote per user
- **Automatic data synchronization** across all connected peers
- **Local storage persistence** for poll recovery
- **Responsive design** works on desktop and mobile
- **No server required** - uses PeerJS free signaling service
## How to Use
1. **Open the app** in your browser (open `index.html`)
2. **First user (Host)**: Leave the Peer ID field empty and click "Connect to Host"
3. **Copy your Peer ID** using the "Copy Your Peer ID" button
4. **Share your Peer ID** with other users (via chat, email, etc.)
5. **Other users**: Paste the host's Peer ID and click "Connect to Host"
6. **Create a poll** with question and options
7. **Vote** by clicking on options (one vote per person)
8. **Watch results** update in real-time across all devices
## Technical Details
- **P2P Library**: PeerJS (WebRTC-based)
- **Frontend**: Vanilla JavaScript with modern CSS
- **Data Sync**: Custom conflict resolution for concurrent operations
- **Storage**: localStorage for basic persistence
- **Network**: Full mesh topology where each peer connects to all others
## File Structure
```
├── index.html # Main application
├── css/
│ └── styles.css # Application styling
└── js/
├── app.js # Main application logic
├── peer-manager.js # P2P connection handling
├── poll-manager.js # Poll data and sync logic
└── ui-controller.js # UI interactions
```
## Browser Support
Requires modern browsers with WebRTC support:
- Chrome 23+
- Firefox 22+
- Safari 11+
- Edge 79+
## Development
Simply open `index.html` in a browser - no build process required. For testing with multiple peers, open the app in multiple browser tabs or windows.
