DevOps for JavaScript (Node.js) Developers

This book is a practical guide for JavaScript developers who want to master DevOps practices and learn how to professionally deploy and maintain Node.js applications. If you are tired of manual deployment, frequent server configuration errors, and want to automate all processes — from commit to production — this book is for you.

The book is structured to guide the reader through the entire journey: from basic DevOps concepts to creating a complete software delivery pipeline. You will learn how to containerize Node.js applications using Docker, orchestrate them in Kubernetes, set up CI/CD with GitHub Actions and GitLab CI, and monitor system performance in real time.

Who is this book for?

• Node.js developers who want to deploy their own projects independently
• Fullstack engineers looking to expand their skills to the infrastructure level
• Team leads and technical leads responsible for development and delivery processes
• Anyone who wants to stop fearing the command line and DevOps tools

What will you learn from this book?

• How to set up a Docker image for a Node.js application with production optimizations
• How to organize a CI/CD pipeline with testing, linting, and automated deployment
• How to deploy an application in Kubernetes (Minikube, Managed K8s)
• How to manage configurations and secrets (12 Factor App)
• How to set up monitoring and alerting (Prometheus + Grafana)
• How to work with logs in distributed systems
• How to ensure fault tolerance and scaling of Node.js services

Why is this book useful?

Unlike general DevOps books, this material is focused specifically on the JavaScript and Node.js ecosystem. All examples, configurations, and best practices are adapted to the specifics of working with V8, asynchronicity, the npm package manager, and popular frameworks (Express, Fastify, NestJS). You won't just read theory — you will be able to immediately apply the knowledge in practice using ready-made templates and scripts from the book.

The book is suitable for both DevOps beginners and experienced developers who want to systematize their knowledge. After reading it, you will be able to independently set up a complete development and delivery cycle for any Node.js project — from a small API to a microservice architecture.
