🚀 Quick Start

Production Setup

Step 1: Get CA-Signed Certificate (Let's Encrypt)

sudo certbot certonly --standalone -d fleet.yourdomain.com

Step 2: Configure Security

{
  "quic": {
    "security": {
      "enableTLS": true,
      "verifyPeer": true,
      "certificates": {
        "certPath": "/etc/letsencrypt/live/fleet.yourdomain.com/fullchain.pem",
        "keyPath": "/etc/letsencrypt/live/fleet.yourdomain.com/privkey.pem",
        "caPath": "/etc/letsencrypt/live/fleet.yourdomain.com/chain.pem"
      }
    }
  }
}

Step 3: Initialize Secure Transport

import { createSecureQUICTransport } from './core/transport/SecureQUICTransport';

const transport = await createSecureQUICTransport({
  host: 'fleet.yourdomain.com',
  port: 4433,
  security: {
    certPath: '/path/to/fullchain.pem',
    keyPath: '/path/to/privkey.pem',
    caPath: '/path/to/chain.pem'
  }
});

Development Setup

For local testing only:

# Generate self-signed certificate
openssl req -x509 -newkey rsa:4096 -keyout dev-key.pem -out dev-cert.pem \
  -days 365 -nodes -subj "/CN=localhost"

# Set environment
export NODE_ENV=development
