GraphQL on TypeScript: A Modern Approach to APIs

This book is a comprehensive guide to developing modern APIs using the GraphQL and TypeScript stack. GraphQL changes the approach to client-server interaction, while TypeScript adds strict typing and predictability, which is especially important in large projects.

The author guides the reader step by step from creating the first schema to building a complete production-ready solution. You will learn how to design a type-safe API, avoid common mistakes, and leverage all the benefits of static typing to improve code reliability.

Who is this book for?

• Backend developers who want to master GraphQL with TypeScript
• Fullstack engineers looking to simplify frontend-backend interaction
• Teams migrating from REST to GraphQL
• Developers who value code reliability and readability

What you will learn from this book:

• GraphQL fundamentals: types, queries, mutations, subscriptions
• Schema design aligned with business logic
• TypeScript integration: code-first and schema-first approaches
• Working with resolvers, context, and Dataloader
• Authentication, authorization, and protection against N+1 queries
• Testing GraphQL endpoints
• Caching, monitoring, and deployment

The book contains numerous practical examples, ready-to-use snippets, and templates. Each chapter includes exercises to reinforce the material. Special attention is given to best practices: from code organization to performance optimization.

After reading, you will be able to independently design and develop scalable GraphQL services in TypeScript, confidently use modern tools (Apollo Server, TypeGraphQL, GraphQL Code Generator), and integrate GraphQL into existing projects.

The book is suitable both for beginners familiar with the basics of TypeScript and Node.js, and for experienced developers looking to systematize their knowledge or find a reference for complex tasks.
