GraphQL on TypeScript: A Complete Guide to Modern APIs

Modern web development requires flexible and high-performance APIs. GraphQL has become the de facto standard for building efficient interfaces between client and server. The book "GraphQL on TypeScript" is a practical guide that will take you from the basics to creating production-ready solutions.

The author, Alexey Sokolov, a senior developer with 10 years of experience, shares proven techniques and best practices. You will learn how to design schemas, write resolvers, work with databases, and optimize performance.

Who is this book for?

• JavaScript/TypeScript developers looking to master GraphQL
• Backend engineers transitioning from REST to GraphQL
• Fullstack developers building modern APIs
• Team leads implementing new technologies in projects

What you will learn:

• GraphQL fundamentals: types, queries, mutations, subscriptions
• Designing efficient schemas with TypeScript
• Working with Apollo Server and Apollo Client
• Integration with PostgreSQL, MongoDB, and other databases
• Query optimization: N+1 problem, DataLoader, caching
• Authentication and authorization in GraphQL
• Testing and debugging GraphQL APIs
• Pagination, file uploads, real-time subscriptions
• Migrating from REST to GraphQL

The book contains over 50 practical examples, ready for use. Each chapter includes exercises to reinforce the material. You will learn not just to write code, but to create architecturally sound solutions.

Special attention is given to TypeScript: schema typing, type generation, IDE integration. You will learn how TypeScript helps avoid errors at compile time and makes code self-documenting.

At the end of the book, you will create a full-fledged application — a task management system with a GraphQL API, authentication, subscriptions, and optimized queries.

This book is suitable for both beginners and experienced developers. Beginners will find step-by-step instructions, while professionals will get an in-depth analysis of complex topics and production patterns.

Join the community of developers using GraphQL and TypeScript. Make your APIs fast, flexible, and reliable.
