🔧 Configuration

Environment Variables

# Server
PORT=7860
HOST=0.0.0.0

# Database
DATABASE_URL=sqlite+aiosqlite:///./crypto.db

# Optional: API Keys (for external services)
COINGECKO_API_KEY=your_key_here
BINANCE_API_KEY=your_key_here
ETHERSCAN_API_KEY=your_key_here

Cache Configuration

// static/shared/js/core/config.js
export const CACHE_TTL = {
  health: 10000,      // 10 seconds
  market: 30000,      // 30 seconds
  sentiment: 60000,   // 1 minute
  news: 300000,       // 5 minutes
  static: 3600000     // 1 hour
};

Polling Configuration

// static/shared/js/core/config.js
export const POLLING_INTERVALS = {
  health: 30000,      // 30 seconds
  market: 10000,      // 10 seconds
  sentiment: 60000,   // 1 minute
  news: 300000,       // 5 minutes
  models: 60000       // 1 minute
};

🐛 Troubleshooting

Issue: Pages not loading

Solution: Check that static files are mounted correctly:

app.mount("/static", StaticFiles(directory="static"), name="static")

Issue: API calls failing

Solution: Verify CORS middleware is configured:

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

Issue: Database errors

Solution: Database uses lazy initialization, errors are non-critical:

try:
    await init_db()
except Exception as e:
    logger.warning(f"Database init skipped: {e}")

Issue: Layout not injecting

Solution: Check paths in layout-manager.js:

const LAYOUT_PATHS = {
  header: '/static/shared/layouts/header.html',
  sidebar: '/static/shared/layouts/sidebar.html',
  footer: '/static/shared/layouts/footer.html'
};
