TypeScript and Kubernetes: Developing and Deploying Cloud Applications

The book "TypeScript and Kubernetes: Developing and Deploying Cloud Applications" is a practical guide for developers who want to master a modern technology stack for building scalable cloud services. The author, Alexey Petrov, a senior developer with 10 years of experience, will guide you step by step from writing a TypeScript application to its full deployment in a production Kubernetes cluster.

What is this book about?

The book covers the complete development cycle:

• TypeScript for back-end: project setup, working with types, asynchrony, creating REST APIs and gRPC services.
• Containerization with Docker: creating efficient Dockerfiles for TypeScript, multi-stage builds, optimizing image size.
• Kubernetes basics: Pods, Deployments, Services, ConfigMaps, Secrets, Ingress — all with real-world examples.
• Microservice architecture: service design, inter-service communication, error handling, retries, and timeouts.
• CI/CD pipelines: automated building, testing, and deployment with GitHub Actions and GitLab CI.
• Monitoring and logging: Prometheus, Grafana, Loki — how to track the state of your services.

Who is this book for?

The book is suitable for:

• JavaScript/TypeScript developers who want to move from monoliths to microservices.
• DevOps engineers looking to gain a deeper understanding of how applications work in Kubernetes.
• Full-stack developers aiming to master cloud infrastructure tools.
• Team leads and architects planning a migration to a microservice architecture.

What will you learn and be able to do after reading?

• Write type-safe back-end services in TypeScript using Express, Fastify, or NestJS.
• Create optimized Docker images for Node.js applications.
• Deploy and scale services in Kubernetes using manifests and Helm charts.
• Organize a seamless CI/CD pipeline with automated deployment.
• Configure monitoring, alerting, and centralized logging.
• Apply fault tolerance patterns: circuit breaker, retry, bulkhead.

All code examples are available in the repository on GitHub. The book is written in a lively style, with an emphasis on practice and real-world cases. It is the ideal starting point for those who want to write modern cloud applications in TypeScript and manage them using Kubernetes.
