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 build a reliable code delivery pipeline. If you write in Node.js but feel uncertain about deployment, containerization, or setting up CI/CD — this edition is for you.

The book starts with the basics: you will understand why a developer needs DevOps skills and how they accelerate product delivery. Then, step by step, you will master key tools and concepts:

• Containerization with Docker — creating lightweight and reproducible environments for Node.js applications, optimizing images, and working with multi-stage builds.
• Orchestration and Management — a basic introduction to Docker Compose and Kubernetes for running microservices.
• CI/CD Pipelines — setting up automated builds, testing, and deployment using GitHub Actions, GitLab CI, and Jenkins.
• Monitoring and Logging — implementing Prometheus, Grafana, and the ELK stack for tracking the state of Node.js applications.
• Cloud Technologies — deployment on AWS, Google Cloud, and VPS, working with load balancers and databases.
• Security — managing secrets, vulnerability scanning, and best practices for production.

The book is written with a focus on practice: each section contains real code examples, configuration files, and step-by-step instructions. You will not just learn the theory, but will be able to immediately apply it in your projects.

Who is this book for?

• Node.js developers who want to independently deploy and maintain their applications.
• Full-stack engineers striving to automate routine tasks and speed up the release cycle.
• Team leads and technical leads implementing a DevOps culture in their team.

After reading, you will be able to: set up a Docker environment for any Node.js project, design reliable delivery pipelines, monitor performance, and quickly respond to incidents. The book bridges the gap between writing code and its stable operation in production — a skill that is critically important for any professional developer today.

This is not a collection of abstract theories, but a tool that will make you a more independent and valuable specialist. Elevate the level of your projects with DevOps!
