GraphQL in C++: Creating Modern APIs

The book "GraphQL in C++" is the first practical guide of its kind that bridges the gap between the power of the C++ language and modern approaches to building APIs. If you want to go beyond REST and create efficient, type-safe, and easily extensible servers, this book will become your indispensable assistant.

What is this book about?

The book consistently guides the reader from the basics of GraphQL to creating a full-fledged production-ready server in C++. You will learn how to design schemas, write resolvers, handle queries, and manage subscriptions. Special attention is paid to performance, safe memory management, and integration with existing C++ projects.

Who is this book for?

• Backend developers in C++ who want to master a modern API protocol
• Engineers transitioning from REST to GraphQL and looking for practical examples in their native language
• Systems programmers building high-load, low-latency services
• Students and anyone interested in API architecture and modern C++

What will you learn?

• How to install and configure the graphql-cpp library or implement your own parser
• Principles of designing type-safe schemas using C++ templates
• Developing efficient resolvers with asynchronous processing and caching
• Working with Subscriptions via WebSocket in real time
• Performance optimization: batch loading, DataLoader, and minimizing overhead
• Testing a GraphQL server: unit tests, integration tests, and benchmarks
• Integration with databases (PostgreSQL, Redis) and microservices
• Security: protection against N+1 queries, query depth limiting, and authentication
• Deploying the server in Docker and monitoring with Prometheus

Why choose this book?

Unlike abstract manuals, all examples in the book are written in modern C++17/20, use real-world scenarios, and are accompanied by detailed comments. You won't just read theory — you'll be able to immediately apply the knowledge in your own project. The book contains ready-made code snippets that can be adapted to any architecture.
