Web Development in Go (Golang): From Basics to Deployment

This book is your practical guide to web development in the Go language (Golang). It is perfect both for experienced developers looking to master a new language for backend development, and for beginners who are already familiar with the basics of programming and want to create modern, fast, and reliable web services.

The author, Alexey Sokolov, a senior developer with 10 years of experience, will guide you step by step from the very basics of the language to the professional deployment of a finished application into production.

What you will learn from the book:

• Go Basics: syntax, data types, working with goroutines and channels, structures and interfaces. You will understand why Go is so popular for high-load systems.
• Creating an HTTP Server: from a simple "Hello World" to configuring a router, middleware, handling JSON, and working with forms.
• Working with Databases: connecting to PostgreSQL and MySQL, writing SQL queries, using ORM (GORM) and connection pools.
• Authentication and Security: JWT tokens, OAuth 2.0, CSRF and XSS protection, password hashing.
• REST API and Microservices: designing a clean REST API, error handling, versioning, creating a microservice architecture.
• Testing: unit tests, integration tests, mocks, and testing HTTP endpoints.
• Deployment and DevOps: building Docker images, deploying to VPS, Heroku, and AWS, setting up CI/CD with GitHub Actions, monitoring, and logging.

Why this book on PythonLib? We chose it because it is not overloaded with theory — each chapter contains a real code example that you can immediately run and modify. At the end of the book, you will create a full-fledged project: a Task Manager service with users, authorization, a REST API, and a Docker image ready for deployment.

The book is suitable for:

• Developers in Python, Java, PHP who want to switch to Go.
• Students and junior developers looking to master backend development.
• Team Leads and architects seeking a practical guide to designing in Go.
