Practical Guide to RESTful Web Services in Go

Introduction

The book «Hands-On RESTful Web Services with Go» was published in 2019 and immediately attracted the attention of developers learning the Go language (Golang). The author, Naren Yellavula, is an experienced software engineer specializing in backend development and microservice architecture. In this review, we will break down what makes the book useful, who it is intended for, and what practical skills you will gain after reading it.

What the book is about

The book is a practical guide to creating RESTful web services in Go. It covers the full development cycle: from API design and router selection to testing, documentation, and deployment in a production environment. The main focus is on real-world examples and ready-to-use solutions. The author systematically guides the reader through all stages, starting with the basics of HTTP and ending with advanced topics such as authentication, working with PostgreSQL, and containerization with Docker.

Who this book is for

The book is aimed at developers already familiar with the basics of Go (syntax, data types, functions, structures). It will be useful for:

• Backend developers wanting to learn how to create REST APIs in Go;
• Engineers transitioning from other languages (Python, Java, PHP) to Go;
• Students and novice programmers who want to learn web development hands-on;
• Team leads and architects looking for proven patterns for building microservices.

What the reader will learn (list)

After studying the book, you will be able to:

• Design RESTful APIs following best practices (resource naming, versioning, response codes);
• Use the standard net/http library and popular routers (gorilla/mux, chi);
• Work with databases (PostgreSQL, MySQL) via drivers and ORM (GORM);
• Implement authentication and authorization (JWT, OAuth2);
• Write unit tests and integration tests for your API;
• Document your API using Swagger/OpenAPI;
• Containerize the application with Docker and deploy it to the cloud (AWS, GCP);
• Optimize performance and handle errors.

Strengths

1. Practical focus. Each chapter contains code that can be run immediately and adapted to your own project. No dry theory — only working examples.

2. Structured approach. The book is divided into 12 chapters, each dedicated to a separate topic. The material progresses from simple to complex, allowing you to gradually deepen your knowledge.

3. Relevance. Despite being from 2019, the described approaches (REST, JSON, JWT, Docker) remain industry standards. The book is not tied to outdated libraries.

4. Testing coverage. A separate chapter is devoted to testing — this is rare for Go books, but critically important for production code.

5. Real-world scenarios. The author covers not just "toy" examples, but typical problems: pagination, filtering, error handling, CORS.

Who is recommended

The book will be especially useful for those who want to quickly move from theory to practice and get ready-made templates for building reliable web services. If you already know Go at a basic level and want to delve into web development, this is an excellent choice. The book is also suitable for teams transitioning to a microservice architecture, as a reference for standard solutions.

Overall, «Hands-On RESTful Web Services with Go» is a high-quality practical guide that will help you become a confident REST API developer in Go. We recommend it for study on PythonLib.
