# 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

├── 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.
