Mastering REST APIs with Go: A Developer's Guide to Designing, Building, and Securing Modern Web APIs with Practical Go Programming

In today's backend development landscape, clean and efficient APIs are the backbone of scalable and maintainable software. Mastering REST APIs with Go gives developers the technical foundation, practical skills, and production-ready insights needed to build robust and secure web APIs using the Go programming language.

This book goes beyond the basics. You'll start with essential Go fundamentals and HTTP handling, then move confidently into building real-world RESTful APIs from scratch. You'll learn how to structure scalable applications, implement service and repository patterns, manage database connections efficiently, and handle errors gracefully. As your skills grow, the book walks you through authentication with JWT, route protection, rate limiting, HTTPS enforcement, testing strategies, and deployment to modern cloud platforms like Render, DigitalOcean, and AWS.

Each chapter is hands-on, filled with complete working examples and real-world scenarios that mirror what professional backend engineers face in production environments. You'll write code that's idiomatic, testable, maintainable, and ready for real users.

Whether you're a Go developer leveling up your backend skills or a backend engineer adopting Go for its performance and simplicity, this book is designed to give you everything you need to succeed in building modern, secure, and high-performing REST APIs.

What You'll Learn:

• How to design and structure REST APIs using idiomatic Go
• Secure user registration, JWT authentication, and authorization middleware
• How to test endpoints using httptest, write unit tests, and use mocks for isolation
• Pagination, filtering, sorting, API versioning, and OpenAPI documentation
• Dockerization, environment configuration, and production deployment strategies
