Vaultys Peer SDK Overview

A decoupled, reusable SDK for peer-to-peer communication built on WebRTC. This SDK provides a clean, interface-based architecture for building peer-to-peer applications with support for messaging, file sharing, audio/video calls, and group communication.

🚀 Why Vaultys Peer SDK?

The Challenge of P2P Development

Building peer-to-peer applications traditionally requires:

• Deep understanding of WebRTC complexities
• NAT traversal and STUN/TURN configuration
• Connection management and state handling
• Implementing reconnection logic
• Building message protocols from scratch
• Handling edge cases and network failures

Our Solution

Vaultys Peer SDK abstracts away these complexities while maintaining flexibility:

• Batteries Included: Powered by VaultysId for enterprise-grade DID management
• Scale Effortlessly: Lazy loading enables managing thousands of peers with zero overhead
• Your Infrastructure: Bring your own signaling server for complete control
• Developer First: Clean APIs, TypeScript support, and comprehensive documentation

✨ Key Features

🔋 Powered by VaultysId

Built on VaultysId, the leading open-source Decentralized Identity System. Get W3C-compliant DIDs, verifiable credentials, and key management out of the box. Passkey and FIDO2 authentication has never been so easy! Enable passwordless login with just one line of code - your users can authenticate with fingerprint, Face ID, or security keys.

⚡ Lazy Loading Magic

Manage thousands of peers without performance impact. Connections are established only when messages are exchanged, making it perfect for large-scale applications.

🏗️ Infrastructure Flexibility

• Bring your own signaling server today
• Configure custom STUN/TURN servers
• Deploy on-premise or in the cloud
• Coming Soon: Bring your own DID system

🔐 Security First

• Passwordless authentication with passkeys/FIDO2
• Biometric and security key support
• End-to-end encryption support
• DID-based authentication
• No central message storage
• Privacy by design

📦 TypeScript Native

Full TypeScript support with comprehensive type definitions, enabling better IDE support and catching errors at compile time.

🚦 Getting Started

Quick Installation

# npm
npm install @vaultys/peer-sdk

# yarn
yarn add @vaultys/peer-sdk

# pnpm
pnpm add @vaultys/peer-sdk

Your First P2P App

import { setupVaultysPeerSDK } from '@vaultys/peer-sdk';
import { VaultysId } from '@vaultys/id';

// Authenticate with passkey - incredibly simple!
const identity = await VaultysId.authenticate({
  passkey: true  // That's it! Biometric/security key auth
});

// Initialize with authenticated identity
const peer = setupVaultysPeerSDK({ identity });
await peer.initialize(identity.did);

// Connect to a friend (lazy - no connection yet!)
const friend = await peer.addContact('did:vaultys:bob');

// Send a message (connection established now!)
await peer.sendMessage(friend.did, 'Hello P2P World! 🌍');

// Listen for messages
peer.on('message-received', (msg) => {
  console.log(`${msg.from}: ${msg.content}`);
});
