2af5da59c4 Implement P2P polling app with Yjs and WebRTC
Uses Yjs CRDTs for conflict-free shared state and y-webrtc for
peer-to-peer data exchange. Users can add poll options and vote/unvote,
with all changes syncing in real-time across connected peers.

# P2P Poll App # P2P Poll App
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. A peer-to-peer polling app where users can add options and vote on them. All data syncs directly between browsers using WebRTC — no central server stores any poll data.
## Features ## How It Works
- **Real-time P2P sync** — poll options and votes sync instantly across all connected peers via WebRTC - **Yjs CRDTs** handle shared state — concurrent edits from different peers merge automatically without conflicts
- **Collaborative poll title** — editable title that syncs between all participants - **y-webrtc** establishes direct WebRTC connections between browsers (a public signaling server is used only for peer discovery)
- **One vote per user** — each peer gets a stable ID, enforcing one vote per person per option - Each user gets a stable random ID (stored in localStorage) ensuring one vote per user per option
- **Vote/Unvote toggle** — change your mind anytime - Polls are identified by room name, shareable via URL
- **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

``` ```
Open `http://localhost:5173/?room=my-poll` in multiple browser tabs to test. Open `http://localhost:5173` in your browser. To share a specific poll, use the `?room=` query parameter:
To test across devices on the same network: ```
http://localhost:5173/?room=my-poll
```
Share this URL with others to join the same poll.
## Cross-Device Testing
```bash ```bash
npm run dev -- --host npm run dev -- --host
``` ```
Then open the URL shown in the terminal on other devices. Then open `http://<your-local-ip>:5173/?room=test` on another device on the same network.
## How It Works ## Tech Stack
1. Each browser tab creates a Yjs document and connects to other peers via WebRTC - [Yjs](https://yjs.dev/) — CRDT library for conflict-free shared state
2. Poll options and votes are stored in Yjs shared data types (Y.Map) - [y-webrtc](https://github.com/yjs/y-webrtc) — WebRTC provider for P2P connectivity
3. Changes propagate automatically to all connected peers using CRDTs - [Vite](https://vite.dev/) — Dev server and bundler
4. A public signaling server handles peer discovery; all poll data flows directly between browsers - Vanilla JS — No framework dependencies
