TypeScript and Microservices: From Idea to Production

The book "TypeScript and Microservices" is a comprehensive practical guide that will take you from the basics of designing distributed systems to deploying a finished product to production. The author, Alexey Voronov, a senior developer with 10 years of experience, shares real-world cases and proven design patterns adapted to the TypeScript ecosystem.

What is this book about?

Unlike abstract theoretical materials, the book focuses on specific tasks. You will learn:

• How to choose an architecture: comparison of monolith, SOA, and microservices; when microservices are justified and when they are not.
• TypeScript in microservices: strong typing as a tool for combating errors at service boundaries; generating clients from schemas.
• NestJS: building services on one of the most popular frameworks for Node.js with support for decorators and modularity.
• Inter-service communication: REST, gRPC, message queues (RabbitMQ, Kafka) — when and what to use.
• Docker and orchestration: containerization, Docker Compose for local development, basics of Kubernetes.
• Testing: unit tests, integration tests, contract testing with Pact.
• CI/CD and monitoring: setting up pipelines, logging, tracing (OpenTelemetry), metrics.

Who is this book for?

The book is intended for a wide range of readers:

• Junior developers (1+ year of experience) — will get a clear roadmap for transitioning from simple applications to distributed systems.
• Middle developers — will deepen their knowledge of patterns, timeouts, sagas, and idempotency.
• Senior developers and architects — will find ready-made recipes for common problems: circuit breaker, retry, bulkhead.
• Technical leaders — will be able to assess the risks and trade-offs of different approaches.

What will you get after reading?

You will be able to independently design and implement a system of 3–10 microservices, configure their interaction, ensure fault tolerance, and set up monitoring. All code examples are available in the repository and ready to run. The book teaches not just how to write code, but how to make informed architectural decisions.

This is not a translation of a Western bestseller, but original material that takes into account the specifics of Russian-language development: infrastructure features, typical beginner mistakes, and real-world cases from the author's experience. If you want to level up and stop being afraid of distributed systems, this book is for you.
