GraphQL in C++: Developing Efficient and Flexible APIs

The book "GraphQL in C++" is a practical guide to creating efficient and flexible APIs using the C++ language. In modern web development, GraphQL is becoming the de facto standard for building client-server interactions, while C++ remains one of the most powerful and performant languages. This book combines the best of both worlds, allowing you to create high-load, reliable servers with minimal resource consumption.

The book starts with the basics: you will learn what GraphQL is, how it differs from REST, and how the type system works. The author then delves into the details of implementation in C++: from setting up the environment and choosing libraries (e.g., cppgraphqlgen or graphql-cpp) to building schemas, resolvers, and handling complex queries. Special attention is paid to performance and optimization — you will learn to write code that processes thousands of queries per second without sacrificing readability and maintainability.

The book is intended for C++ developers who want to master modern approaches to creating APIs. Are you already familiar with C++ syntax, the STL, and the basics of network programming? Then this book will be your guide to the world of GraphQL. If you are just starting to learn C++, it is recommended to first master the basic concepts of the language, although the author provides all necessary explanations.

The reader will learn:

• How to design type-safe GraphQL schemas in C++
• How to implement resolvers for fields, mutations, and subscriptions
• How to optimize queries using batch loading (DataLoader)
• How to integrate GraphQL with existing C++ projects and databases
• How to test GraphQL servers and handle errors
• How to work with authentication, authorization, and caching

The book contains many practical examples, ready-to-use code snippets, and architectural patterns. You will not just study theory but will be able to immediately apply the knowledge in practice — create your first GraphQL server in C++ and deploy it in a production environment. Each chapter concludes with exercises to reinforce the material.

"GraphQL in C++" is not just a book about technology; it is your assistant in creating fast, scalable, and maintainable APIs. If you want to take your C++ development skills to the next level and master a modern approach to building server applications — this book is for you.
