GraphQL on JavaScript (Node.js): The Complete Guide

This book is a comprehensive practical guide to building modern APIs using GraphQL on the Node.js platform. Unlike REST, GraphQL allows clients to request only the necessary data, minimizing traffic and speeding up development. The book will take you from the very basics to deploying production-ready solutions.

Who this book is for:

• Node.js backend developers looking to master an alternative to REST API
• Frontend developers seeking to understand how modern APIs work
• Fullstack engineers who want to build flexible and efficient server applications
• Tech leads evaluating the adoption of GraphQL in their projects

What you will learn:

• GraphQL fundamentals: types, schemas, queries, mutations, and subscriptions
• Setting up Apollo Server 4 and Express.js for GraphQL
• Building scalable schemas using GraphQL Schema Language
• Writing efficient resolvers and handling errors
• Performance optimization: DataLoader, caching, batch queries
• Authentication and authorization at the schema level
• Working with databases: MongoDB, PostgreSQL, SQLite
• Real-time subscriptions via WebSockets
• Testing GraphQL APIs with Jest and Apollo Client
• Documenting APIs with GraphQL Playground and GraphiQL
• Deploying on Vercel, AWS Lambda, and Docker

Why this book is unique:

Each chapter contains real code examples ready for use. You won't just read theory — you will build a complete application: a blog with comments, a like system, and search. All examples are accompanied by explanations and industry best practices.

The book is suitable for beginners with basic knowledge of JavaScript and Node.js, as well as experienced developers looking to systematize their knowledge. After reading, you will be able to confidently design, develop, and maintain GraphQL servers of any complexity.

The author is a practicing developer with 8 years of experience in Node.js and a contributor to GraphQL Foundation open-source projects. The material is based on real-world experience implementing GraphQL in high-load projects handling millions of requests per day.
