TypeScript and Microservices: From Idea to Production

The book "TypeScript and Microservices" is a comprehensive practical guide to designing, developing, and deploying distributed systems in TypeScript. The author, Alexey Vorontsov, a backend architect with 10 years of experience, shares proven patterns and real-world cases from commercial development.

What is this book about?

The book covers the full lifecycle of a microservice application:

• Architecture and Design: principles of Domain-Driven Design, strategies for breaking up a monolith, choosing protocols (gRPC, REST, GraphQL).
• Technology Stack: NestJS as the main framework, RabbitMQ and Kafka for asynchronous communication, Redis for caching.
• Infrastructure: Docker and Docker Compose for local development, Kubernetes for production, CI/CD with GitHub Actions.
• Testing: unit tests with Jest, integration tests with Testcontainers, e2e testing of microservices.
• Observability: logging with Winston, Prometheus metrics, tracing with Jaeger.
• Security: JWT authentication, OAuth2, encryption of inter-service traffic.

Who is this book for?

• Backend developers using Node.js/TypeScript who want to transition from monoliths to microservices.
• Fullstack developers interested in distributed systems.
• Architects looking for practical examples of microservice implementation.
• DevOps engineers working with TypeScript projects.

What will you learn?

• How to properly break an application into microservices and avoid anti-patterns.
• How to set up asynchronous interaction via message queues.
• How to containerize each service and orchestrate them with Kubernetes.
• How to write reliable tests for a distributed system.
• How to set up monitoring and alerting for microservices.
• How to organize seamless deployment with zero downtime.

All code examples are available in the GitHub repository and can be run locally with a single command docker-compose up. The book contains over 50 practical exercises and 3 end-to-end projects: from a simple order service to a full-fledged e-commerce platform.

This is not just theory — you will build a working system from scratch and be able to adapt the knowledge gained to your own projects. Recommended skill level: confident knowledge of TypeScript and a basic understanding of Node.js.
