Master REST API design in Go by building secure, performant, and observable web services using the standard library and idiomatic patterns
Key Features
Build scalable APIs using Gos robust standard library and HTTP tooling Explore security, observability, and testing from a backend engineering perspective Learn foundational REST principles by building a complete Go-based project
Book DescriptionModern REST API Development in Go is a hands-on guide to understanding and applying REST principles using Gos powerful standard library. In an era where interconnected systems demand robust and performant APIs, Go offers the perfect combination of simplicity, performance, and tooling to build modern backend services. This book is centered around a complete, real-world REST API project and guides you through every stage of the development process, from building HTTP handlers to applying authentication and generating OpenAPI documentation. Youll learn to structure your application, handle persistence with common libraries like GORM and Squirrel, apply observability patterns through logging and tracing, and ensure code quality through unit and integration tests. Each concept is grounded in REST theory and backed by idiomatic Go practices, enabling you to build APIs that are not only functional but production-ready. By the end of the book, youll be ready to design, build, and maintain REST APIs in Go.What you will learn
Understand and implement HTTP handlers in Go Create and manage RESTful routes Persist and model data using GORM and Squirrel Secure APIs with JWTs and basic authentication Validate incoming requests with custom logic Log and trace API activity for observability Write unit and integration tests for endpoints Generate API documentation using OpenAPI
Who this book is forThis book is for developers who want to begin building REST APIs using the Go language. Whether youre new to Go or experienced in backend development, youll gain practical skills and foundational knowledge to build secure, performant, and maintainable APIs. Ideal for backend engineers, system integrators, and full-stack developers entering the Go ecosystem.
