# 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.
|
||||
* **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.

Check out the [deployment documentation](https://nuxt.com/docs/getting-started/deployment) for more information.
|
||||
- The app uses public signaling through `y-webrtc` for MVP simplicity.
|
||||
- Poll state is not stored on an application server.
|
||||
- WebRTC connectivity can still depend on the network environment of the participating peers.
