DevOps for TypeScript Developers: From Monolith to Microservices

Modern TypeScript development requires not only excellent knowledge of the language, but also an understanding of application deployment, scaling, and maintenance processes. The book "DevOps for TypeScript Developers" is a bridge between clean code writing and industrial project operation. The author, Alexey Petrov, a senior DevOps engineer with 10 years of experience, shares proven practices adapted specifically for the TypeScript and Node.js ecosystem.

What is this book about?

This is not dry theory, but a practical guide built on real-world tasks. You will go from setting up a local environment to a full CI/CD pipeline and microservice orchestration. The book covers all key aspects of DevOps in the context of TypeScript:

• Build and Packaging: Configuring the TypeScript compiler, optimizing bundles (Webpack, esbuild), creating Docker images for Node.js applications (NestJS, Express) and frontend (React, Angular).
• CI/CD Pipelines: Step-by-step setup of GitHub Actions and GitLab CI for TypeScript projects: linting, testing (Jest, Vitest), building, publishing packages to npm, and deploying to the cloud.
• Containerization and Kubernetes: Creating lightweight multi-stage Docker images, working with Docker Compose for local development, deploying to Kubernetes (minikube, k3s), managing ConfigMap and Secrets.
• Monitoring and Logging: Integrating OpenTelemetry, setting up metrics (Prometheus), visualization (Grafana), and centralized log collection (ELK/EFK stack) for TypeScript services.
• Security and Infrastructure as Code: Using Terraform/Pulumi to manage cloud infrastructure (AWS, GCP), configuring SSL, managing environment variables.

Who is this book for?

The book is intended for TypeScript developers of any level who want to:

• Automate routine processes and get rid of manual deployment.
• Understand how their code works in a production environment.
• Learn to design scalable microservice architectures.
• Master DevOps tools without diving into deep system administration.

A confident command of TypeScript and basic familiarity with the command line are sufficient.

What will you learn?

• How to set up a fast and reliable CI/CD pipeline for TypeScript projects.
• How to package a NestJS, Express, or Next.js application into a Docker container.
• How to deploy microservices to Kubernetes and configure a service mesh.
• How to add monitoring and alerting to sleep soundly.
• How to avoid common mistakes when deploying TypeScript applications.

The book contains ready-made configuration files, templates, and checklists that can be used immediately in your work. After reading it, you will be able to independently build a complete development and operation cycle for a modern TypeScript project.
