# 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

|
|
||||||

|
|
||||||
│ │ ├── PollOption.ts (single option: vote bar, vote/delete buttons)
|

|
|
||||||
│ │ └── DeadlineTimer.ts (set deadline + countdown display, from project 2)
|
|
||||||
│ └── 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 Verified Polling App
|
||||||
|
|
||||||
|
A decentralized, real-time polling application built with **Nuxt 3**, **Yjs**, and **WebRTC**. This app allows users to create and participate in polls where every vote is cryptographically signed and verified peer-to-peer, ensuring data integrity without a central authority "owning" the results.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 🌟 Key Features
|
||||||
|
|
||||||
|
* **Serverless Real-time Sync:** Uses **Yjs** (CRDTs) and **WebRTC** to sync poll data directly between browsers. No database is required for live updates.
|
||||||
|
* **Persistence with Nitro:** While the logic is P2P, the **Nuxt/Nitro** backend provides a "Snapshot" service to ensure polls persist even after all peers go offline.
|
||||||
|
* **Cryptographic Integrity:** Every vote is signed using **RSA-PSS (Web Crypto API)**. Each user has a unique private key (stored locally via `.pem` files) to ensure votes cannot be forged or tampered with.
|
||||||
|
* **Chained Verification:** Implements a "History-Signing" logic where each new vote signs the entire preceding state of the poll, creating a verifiable chain of trust.
|
||||||
|
* **Privacy First:** Users identify via UUIDs and Public/Private key pairs rather than traditional accounts.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## ⚙️ How It Works
|
||||||
|
|
||||||
|
### 1. Identity Creation
|
||||||
|
When a new user is created, the system generates a unique **UUID (User ID)** and an **RSA Key Pair**. The user is prompted to save their **Private Key** as a `.pem` file, named after their User ID (e.g., `550e8400-e29b.pem`). This file acts as their "Passport"—it is never uploaded to the server and must be kept secure by the user.
|
||||||
|
|
||||||
|
### 2. Authentication
|
||||||
|
Upon returning to the app, users load their local `.pem` file. The application extracts the Private Key for signing and the UUID for identification. No passwords or central servers are involved in this local-first login process.
|
||||||
|
|
||||||
|
### 3. Joining a Poll
|
||||||
|
When a user joins a poll, the app fetches the latest binary snapshot from the server to populate a local **Y.Doc**. This ensures the user sees the current state immediately, even before connecting to other peers.
|
||||||
|
|
||||||
|
### 4. The P2P Mesh
|
||||||
|
The app establishes connections to other active voters via a WebRTC signaling server. Any changes made to the poll (adding options or voting) are broadcasted instantly to all peers using Conflict-free Replicated Data Types (CRDTs) to prevent sync conflicts.
|
||||||
|
|
||||||
|
### 5. Casting a Signed Vote
|
||||||
|
To ensure security, the voting process follows a strict cryptographic chain:
|
||||||
|
* The app captures the current list of votes.
|
||||||
|
* It appends the new vote data (User ID + Timestamp).
|
||||||
|
* It signs the **entire array** (the previous history + the new vote) using the user's RSA private key.
|
||||||
|
* The signed update is merged into the shared Yjs Map and broadcasted.
|
||||||
|
|
||||||
|
### 6. Distributed Verification
|
||||||
|
Whenever a peer receives a new update, they fetch the voter's **Public Key** from the API. They then verify that the signature matches the current state of the poll history. If a signature is invalid or the history has been tampered with, the vote is rejected by the peer's local state.
