This lesson

This lesson teaches Production checklist: the syntax, APIs, and habits you need before advancing in Node.js.

Teams ship Production checklist on every Node.js codebase—skipping it leaves gaps in debugging and code reviews.

You will apply Production checklist in contexts like: REST/GraphQL APIs, BFF layers, CLIs, webhooks, and real-time services (with WebSockets).

Run JavaScript on the Node runner when configured—never mix arbitrary shell commands in lessons.

When functions, arrays, and basic OOP from intermediate lessons are familiar.

Shipping Node APIs means hardened config, observability, and safe defaults—not just node main.mjs on a laptop.

Configuration

  • Node LTS pinned in engines and Docker base image
  • Secrets via env/secret manager—never in repo
  • NODE_ENV=production toggles framework optimizations
  • HTTPS at edge; HSTS when stable

Application

  • Input validation on every mutating route
  • Rate limits on auth and expensive endpoints
  • Helmet or equivalent security headers
  • Graceful shutdown handling
  • npm audit in CI; dependabot/Renovate for updates

Operations

  • Structured logs with request IDs
  • Health and readiness probes
  • Metrics and alerting on 5xx latency
  • Runbooks for rollback and DB migrations

Self-check

  1. Why pin Node version in production?
  2. What belongs on a /health endpoint?
