# P2P Poll App # P2P Poll App
Remove-Item -Recurse -Force node_modules, .next
A peer-to-peer polling application where users create and vote on polls without any central server. All data syncs directly between browsers using WebRTC and CRDTs.
## Features
- **Real-time P2P sync** — poll options and votes sync instantly across all connected peers via WebRTC
- **Collaborative poll title** — editable title that syncs between all participants
- **One vote per user** — each peer gets a stable ID, enforcing one vote per person per option
- **Vote/Unvote toggle** — change your mind anytime
- **Connection status** — see when you're connected and how many peers are in the room
- **Shareable polls** — share via URL with `?room=your-poll-name`
- **No backend required** — runs entirely in the browser
## Tech Stack
- [Yjs](https://yjs.dev/) — CRDT library for conflict-free shared state
- [y-webrtc](https://github.com/yjs/y-webrtc) — WebRTC provider for peer-to-peer connections
- [Vite](https://vitejs.dev/) — Development server and build tool
- Vanilla JavaScript — no framework dependencies
## Getting Started
```bash
npm install
npm run dev
```
Open `http://localhost:5173/?room=my-poll` in multiple browser tabs to test.
To test across devices on the same network:
```bash
npm run dev -- --host
```
Then open the URL shown in the terminal on other devices.
## How It Works
1. Each browser tab creates a Yjs document and connects to other peers via WebRTC
2. Poll options and votes are stored in Yjs shared data types (Y.Map)
3. Changes propagate automatically to all connected peers using CRDTs
4. A public signaling server handles peer discovery; all poll data flows directly between browsers
