 # Minimal MVP Plan: P2P Poll App
 ## Recommendation
 Build the MVP with:
 - Vanilla JS or TypeScript
 - Vite for local dev/build
 - Yjs for shared state
 - `y-webrtc` for browser-to-browser sync
 - `y-indexeddb` for local persistence/offline recovery
 This is the best fit for a small poll app because the data model is tiny, concurrent edits are possible, and Yjs already solves merge/conflict handling while `y-webrtc` gives a direct P2P transport with only signaling infrastructure.
 ## Why This Stack
 ### Recommended: Yjs + y-webrtc
 - Best balance of simplicity and correctness
 - Clients connect directly over WebRTC
 - No custom conflict-resolution logic needed
 - Easy to add offline persistence
 - Good fit for a single shared document/room
 ### Not recommended for the first MVP
 #### PeerJS
 - Very simple transport layer
 - But you must design and maintain your own replication and merge rules
 - Fine for demos with a host-authoritative peer, weaker for true collaborative editing
 #### GUN
 - Fast to prototype realtime shared state
 - But official tutorials commonly use a GUN peer/relay server for shared data
 - For this app, its data model is less explicit than a CRDT and gives less control over vote semantics
 #### Automerge
 - Very capable CRDT and local-first model
 - But heavier than needed for a single small poll
 - Better choice if the project is expected to evolve into a richer collaborative app
 ## MVP Scope
 Ship exactly one shared poll per room.
 Included:
 - Join a poll by opening a shared URL
 - Add a new option
 - Vote for one option
 - Change your vote
 - Realtime updates across peers
 - Local persistence in the browser
 - Basic connection status UI
 Excluded:
 - User accounts
 - Multiple polls per room
 - Option deletion/editing
 - Authentication/authorization
 - Rich presence
 - Advanced discovery
 - Production-grade TURN/signaling deployment
 ## MVP UX
 Keep the interface intentionally small:
 - Poll title at the top
 - Option list with vote counts
 - One button per option to cast vote
 - Small form to add an option
 - Status line showing `connecting`, `connected`, or `offline`
 - Small label showing which option you voted for
 Join model:
 - Room ID in the URL, e.g. `/?room=poll-demo`
 - Users share the URL manually
 Identity model:
 - Generate a local `userId` once and store it in `localStorage`
 - Optional local display name, also stored locally
 ## Shared Data Model
 Use a single Yjs document per room.
 Suggested structure:
 - `poll` as a `Y.Map`
 - `poll.title` as a string
 - `poll.options` as a `Y.Map<optionId, Y.Map>`
 - `poll.votes` as a `Y.Map<userId, optionId>`
 Each option record:
 - `id`
 - `label`
 - `createdBy`
 - `createdAt`
 Important design choice:
 Do not store vote counters as mutable shared numbers for the MVP.
 Instead, derive counts from `votes`.
 Why:
 - A user changing vote becomes a single write: `votes[userId] = optionId`
 - No double-counting logic
 - Concurrent writes are easier to reason about
 - Rendering counts from `votes` is trivial at this scale
 ## Sync Model
 ### Networking
 - Use `WebrtcProvider(roomId, ydoc)`
 - Start with the default public signaling servers for local development
 - If needed, swap to a self-hosted signaling server later without changing the app model
 ### Persistence
 - Use `IndexeddbPersistence(roomId, ydoc)`
 - This preserves state across reloads and helps when reconnecting after temporary disconnects
 ### Conflict behavior
 - Concurrent option additions merge naturally
 - Concurrent vote changes resolve at the per-user key level
 - Tally is recalculated from the merged vote map
 ## Suggested Project Structure
 ```text
 src/
  main.ts
  app.ts
  state.ts
  sync.ts
  render.ts
  identity.ts
  styles.css
 index.html
 ```
 Responsibilities:
 - `sync.ts`: create Yjs doc, WebRTC provider, IndexedDB provider
 - `state.ts`: shared structures, add option, cast vote, selectors
 - `identity.ts`: local `userId` and optional name
 - `render.ts`: DOM updates
 - `app.ts`: wire events to state and rendering
 ## Implementation Plan
 ### Phase 1: App shell
 - Create Vite app with vanilla TS or JS
 - Add a minimal single-page UI
 - Parse `room` from the URL
 - Generate and persist `userId`
 Success check:
 - App loads
 - Room ID appears in UI
 - User can type in the form
 ### Phase 2: Shared state
 - Add Yjs document
 - Create root shared maps
 - Seed default poll title if missing
 - Observe document updates and re-render UI
 Success check:
 - State exists in one browser tab
 - Refresh keeps local state when IndexedDB is enabled
 ### Phase 3: P2P sync
 - Add `y-webrtc`
 - Join room based on URL room ID
 - Show connection status from provider events
 Success check:
 - Two browsers on different tabs/devices see the same options
 - New options appear in near real time
 ### Phase 4: Voting logic
 - Implement `castVote(optionId)` as `votes.set(userId, optionId)`
 - Derive tallies from `votes`
 - Highlight the local user’s current vote
 Success check:
 - Votes update live across peers
 - Changing vote updates counts correctly
 ### Phase 5: Basic hardening
 - Trim/validate option labels
 - Prevent empty options
 - Ignore duplicate labels case-insensitively for MVP
 - Show simple offline/connecting text
 Success check:
 - Basic misuse does not break the UI
 - Reconnect restores updates
 ## Minimal API Surface
 These functions are enough for the first build:
 - `getRoomId(): string`
 - `getUserId(): string`
 - `initSync(roomId): AppSync`
 - `ensurePollInitialized()`
 - `addOption(label: string)`
 - `castVote(optionId: string)`
 - `getViewModel(): PollViewModel`
 - `render(viewModel)`
 ## Risks And MVP Mitigations
 ### NAT / WebRTC connectivity
 Risk:
 - Some peer pairs may fail to connect in restrictive networks
 Mitigation:
 - Accept this for MVP
 - Keep signaling configurable
 - Add TURN only if testing shows frequent failures
 ### Small public signaling dependency
 Risk:
 - Public signaling is fine for demos, not ideal for production
 Mitigation:
 - Treat it as replaceable infrastructure
 - Self-host later if the prototype is kept
 ### Duplicate or messy options
 Risk:
 - Users may add near-duplicate entries
 Mitigation:
 - Normalize labels
 - Prevent exact duplicates for MVP
 ### No trust/auth model
 Risk:
 - Any participant in the room can add options and vote
 Mitigation:
 - Accept for MVP
 - Frame rooms as small trusted groups
 ## Estimated MVP Size
 For one developer:
 - Initial prototype: 0.5 to 1 day
 - Polished MVP with basic resilience: 1 to 2 days
 Rough code size:
 - 250 to 500 lines plus styles
 ## Nice Next Steps After MVP
 - Copy-link button
 - Participant list / presence
 - Vote limit modes: single-choice or multi-choice
 - Option editing/deletion
 - QR code for room join
 - Self-hosted signaling server
 - PWA packaging for better offline behavior

-# 🗳️ P2P Verified Polling App
+# P2P Poll 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.
+Small peer-to-peer polling app built with `Vite`, `TypeScript`, `Yjs`, `y-webrtc`, and `y-indexeddb`.
---
+## Features
-## 🌟 Key Features
+- single shared poll per room
 - add options collaboratively
 - one vote per user, changeable at any time
 - peer-to-peer sync over WebRTC
 - local browser persistence for refresh/reconnect recovery
 - shareable room URL
-* **Serverless Real-time Sync:** Uses **Yjs** (CRDTs) and **WebRTC** to sync poll data directly between browsers. No database is required for live updates.
+## Run locally
 * **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.

 ## 🛠️ Tech Stack
 * **Framework:** [Nuxt 3](https://nuxt.com/) (Vue 3 + TypeScript)
 * **Conflict-Free Replicated Data Types (CRDT):** [Yjs](https://yjs.dev/)
 * **P2P Transport:** `y-webrtc`
 * **Security:** Web Crypto API (SubtleCrypto)
 * **Backend/Storage:** Nitro (Nuxt's server engine) with filesystem storage drivers

+## Notes
-```bash
+- The app uses public signaling through `y-webrtc` for MVP simplicity.
-# npm
+- Poll state is not stored on an application server.
-npm run preview
+- WebRTC connectivity can still depend on the network environment of the participating peers.
 # pnpm
 pnpm preview
 # yarn
 yarn preview
 # bun
 bun run preview
 ```
