Node.js Process Management

Understanding process management is essential for production Node.js applications. Here's what you need to know.

Best Practices#

Signals:
✓ Handle SIGTERM for graceful shutdown
✓ Handle SIGINT for development
✓ Set timeout for forced shutdown
✓ Log shutdown progress

Error Handling:
✓ Catch uncaught exceptions
✓ Handle unhandled rejections
✓ Exit after uncaught exceptions
✓ Use proper exit codes

Production:
✓ Implement health checks
✓ Monitor memory usage
✓ Use process managers (PM2)
✓ Log to external service

Proper process management ensures reliable Node.js applications. Handle signals for graceful shutdown, manage child processes carefully, and always have proper error handling. Use health checks and monitoring for production visibility.
