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

This book is your practical guide to web development in Go (Golang). You will start with the basics of syntax and data structures, and then step by step build a full-fledged web application ready for deployment on a server. Go is a modern, fast, and reliable language that is ideal for building high-load backend services, microservices, and APIs.

Who this book is for:

• Beginner Go developers who want to learn web development from scratch
• Backend developers in other languages (Python, PHP, Java) who want to learn Go
• Programmers seeking to understand how modern web frameworks and HTTP servers work
• Developers who want to learn how to properly test and deploy Go applications

What you will learn from this book:

• Basics of Go syntax: variables, functions, structs, interfaces, goroutines, and channels
• Working with HTTP: creating a router, handling requests, middleware, templating
• Connecting to and working with databases (PostgreSQL, MySQL) using drivers and ORM
• Building a REST API from scratch: endpoint design, validation, JSON
• Authentication and authorization: JWT, sessions, CSRF protection
• Testing: unit tests, integration tests, mocks, and benchmarks
• Deployment: building a Docker image, working with CI/CD, deploying on VPS and cloud platforms
• Best practices: project structure, error handling, logging, performance optimization

The book is written in simple and clear language, containing many code examples and practical exercises. You will not just read theory, but will create a real web application — from the first line of code to running it on a server. All examples are relevant for the latest versions of Go (1.21+) and have been tested in practice.

After reading, you will be able to confidently develop web applications in Go, understand the architecture of modern backend systems, and independently deploy projects to production. This is the ideal book for those who want to become a sought-after Go developer and build reliable, scalable web services.
