DevOps for TypeScript Developers

The book "DevOps for TypeScript Developers" is a practical guide that will help you go beyond writing code and master key DevOps practices. You will learn how to set up continuous integration and delivery (CI/CD), containerize applications, and manage infrastructure while staying within the familiar TypeScript ecosystem.

What is this book about?

The book covers the full DevOps cycle for modern TypeScript projects. You will start with the basics of environment setup and finish with deployment to production. Main topics:

• Setting up CI/CD pipelines with GitHub Actions and GitLab CI for TypeScript projects
• Containerizing Node.js applications using Docker and optimizing images
• Container orchestration: basic principles of Kubernetes and deploying TypeScript services
• Automating testing (unit, integration, e2e) and linting
• Managing configurations, secrets, and environment variables
• Application monitoring and logging: Prometheus, Grafana, ELK stack
• Pipeline security and working with dependency vulnerabilities

Who is this book for?

The book is aimed at TypeScript developers (including Node.js, React, Angular, Nest.js) who want to independently automate build, testing, and deployment processes. It will also be useful for frontend and backend engineers planning to transition into DevOps or SRE. Basic knowledge of TypeScript and the command line is the only requirement.

What will you learn?

• How to set up automatic building and testing on every push to the repository
• How to package a TypeScript application into a Docker image and reduce its size
• How to deploy microservices in Kubernetes using Helm and kubectl
• How to organize monitoring and alerting for real-time error tracking
• How to implement Infrastructure as Code practices (Terraform, Pulumi) for TypeScript projects
• How to speed up the development cycle and reduce the time between commit and release

The book contains numerous code examples, ready-made configuration files, and step-by-step instructions. You will be able to immediately apply the knowledge gained in your own projects. After reading, you will no longer fear the "DevOps magic" and will become a full-fledged engineer capable of managing the entire application lifecycle.

Note: All examples are available on GitHub and adapted for the latest versions of TypeScript 5.x and Node.js 20+.
