GraphQL on TypeScript: A Complete Guide to Modern APIs

The book "GraphQL on TypeScript" is a practical guide to building modern, scalable, and type-safe APIs. The author, experienced developer Andrey Volkov, will sequentially guide you from the basics of GraphQL to building a production-ready server using strict TypeScript typing.

Unlike REST, GraphQL allows clients to request only the data they need, which significantly speeds up development and reduces network load. TypeScript adds a powerful type system to this, which helps avoid errors at the compilation stage and makes the code self-documenting.

Who this book is for:

• Backend developers familiar with JavaScript/TypeScript who want to learn GraphQL
• Full-stack engineers who want to improve the architecture of their APIs
• Frontend developers seeking to understand the internal structure of the server side
• Tech leads evaluating the integration of GraphQL into existing projects

What you will learn from the book:

• GraphQL basics: schema, types, resolvers, mutations, and subscriptions
• TypeScript integration: type generation from schema, code-first and schema-first approaches
• Designing an efficient data schema for real-world applications
• Working with databases (PostgreSQL, MongoDB) through GraphQL
• Authentication, authorization, and API protection
• Performance optimization: N+1 problem, DataLoader, caching
• Resolver testing and integration testing
• Deploying a GraphQL server on Node.js (Express, Apollo Server, Yoga)
• Migrating from REST to GraphQL without service downtime

Book structure: Each chapter contains theory, code examples, and practical tasks. You will start with a simple "Hello World" server and gradually progress to complex scenarios such as service federation and real-time subscriptions.

Why TypeScript? Static typing makes development predictable: you get autocompletion in the IDE, early error detection, and easy refactoring. All examples in the book are written in modern TypeScript using best practices.

The book is suitable for both beginners just getting acquainted with GraphQL and experienced developers who want to systematize their knowledge and learn advanced techniques. After reading it, you will be able to independently design, develop, and maintain high-load GraphQL APIs.

Join the community of developers who are already using GraphQL with TypeScript in production — this book will be your reliable guide to the world of modern APIs.
