DevOps for JavaScript (Node.js) Developers

This book is a bridge between the world of JavaScript development and modern DevOps practices. If you are a Node.js developer who wants to independently configure infrastructure, automate deployment, and manage a production environment, this guide will become your reliable assistant.

Unlike abstract administration manuals, the book focuses specifically on the Node.js ecosystem: you will learn how to effectively containerize Express applications, set up hot reloading in Docker, organize monitoring with PM2 and Prometheus, and automate building and testing using GitHub Actions and GitLab CI.

What you will learn:

• DevOps basics: from server setup to release management
• Containerization of Node.js applications with Docker and Docker Compose (multi-stage builds, image size optimization)
• Orchestration with Kubernetes: deployment, scaling, health checks for Node.js services
• CI/CD pipelines: automated testing, building, and deployment to VPS and cloud platforms
• Monitoring and logging: Winston, Loki, Grafana — a complete stack for Node.js
• Working with databases in containers (PostgreSQL, Redis, MongoDB)
• Security: secrets, SSL, rate limiting, and API protection

Who this book is for:

• Node.js backend developers who want to understand DevOps
• Full-stack engineers managing their own servers
• Team Leads implementing CI/CD in their teams
• Juniors looking to level up to Senior

The book is built on the principle of "from simple to complex": you will start with basic Linux server setup, and by the end, you will be able to deploy a full microservice architecture on Kubernetes with monitoring and auto-scaling. All code examples can be run on your own computer — you only need Node.js and Docker installed.

The author shares real-world experience working with high-load projects, common mistakes, and ways to avoid them. You will get not just theory, but ready-made templates and checklists for a production environment.

Make your Node.js projects stable, scalable, and professionally managed — start with this book.
