1Production Checklist — What You'll Learn
A final, practical checklist to run through before shipping any Node.js application to production.
Here's everything this chapter covers, in the order you'll learn it:
- Robust error handling everywhere
- Input validation on every endpoint
- Security headers (Helmet)
- Rate limiting configured
- CORS configured correctly for your real frontend origin
- Secrets stored in environment variables, never in code
- Automated database backups
- A dedicated health check endpoint
- Structured, centralized logging
- Monitoring and alerting in place
- A meaningful automated test suite
- A reliable, repeatable build process
- HTTPS enforced
- Graceful shutdown on SIGTERM/SIGINT
- A final performance/load check before launch
2Working Example
💻 Example: Production Checklist
JavaScript
▶ Run in Compiler
process.on("SIGTERM", async () => {
console.log("SIGTERM received, shutting down gracefully...");
await server.close();
process.exit(0);
});3Best Practices & Common Pitfalls
💡 Key things to remember:
- This chapter is a checklist, not new syntax — treat it as your final review before every production deployment, and revisit it as your app grows.
❓ Frequently Asked Questions (FAQ)
Q What's the most important thing to understand about production checklist?
Focus on: Security · Monitoring · Logging · Graceful Shutdown · Performance. These are the core building blocks this chapter's examples are built around, and they show up repeatedly in later chapters of this course.
Q Do I need external npm packages for production checklist?
Only where explicitly shown in the code examples above (like Express, Zod, or Socket.IO) — otherwise, this chapter relies entirely on Node.js's own built-in capabilities.
