Deployment Best Practices​

Security​

1. Use public variables for transparency

# .env
VERSION_PUBLIC=1.0.0
NETWORK_PUBLIC=sepolia
SECRET_API_KEY=secret-here  # Private

2. Rotate secrets regularly

# Update API keys periodically
vim .env
eigenx app upgrade my-app

Reliability​

1. Health checks in your app

// Example health endpoint
app.get('/health', (req, res) => {
  res.json({ status: 'healthy', version: process.env.VERSION_PUBLIC })
})

2. Graceful shutdown

process.on('SIGTERM', async () => {
  console.log('SIGTERM received, shutting down gracefully')
  await cleanup()
  process.exit(0)
})

3. Logging

console.log('App started')
console.error('Error occurred:', error)
// Logs are visible via: eigenx app logs
