Deployment Instructions

Quick Start

  1. Start Nautilus API Server:

    cd /home/ubuntu
python3 nautilus_api.py

  2. Configure Frontend:

    // Set API URL in .env
VITE_API_URL=http://localhost:8000

  3. Start Frontend (when React app is built):

    npm run dev

Production Deployment

  1. Backend:

    # Install dependencies
pip install nautilus_trader fastapi uvicorn

# Run with gunicorn for production
gunicorn nautilus_api:app -w 4 -k uvicorn.workers.UvicornWorker

  2. Frontend:

    # Build for production
npm run build

# Serve with nginx or similar

API Configuration

Environment Variables

Backend (nautilus_api.py):

  • No env vars needed (uses defaults)

Frontend (.env):

VITE_API_URL=http://localhost:8000

CORS Configuration

Currently set to allow all origins (*) for development.

For production, update in nautilus_api.py:

app.add_middleware(
    CORSMiddleware,
    allow_origins=["https://your-frontend-domain.com"],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

  3. ✅ Integration tested

Short-term (Enhancement)

  1. Add more Nautilus operations to API
  2. Implement WebSocket for real-time updates
  3. Add authentication/authorization
  4. Expand test coverage

Medium-term (Production)
