Go (Golang): Tips and Best Practices

The book "Go (Golang): Tips and Best Practices" is not another introduction to the language syntax, but a deep dive into professional Go development techniques. It is intended for developers who are already familiar with the basics of the language and want to take their skills to the next level.

What is this book about?

The author has collected and structured many years of experience in commercial Golang development. You will learn how to write not just working code, but efficient, maintainable, and scalable code. The book covers key aspects of professional development:

• Go Idioms and Patterns: how to use goroutines, channels, interfaces, and structs as intended by the language's creators.
• Error Handling: advanced error handling techniques, creating custom error types, and contextual error handling.
• Application Architecture: proper package design, application layers, dependency injection, and clean architecture in Go.
• Testing and Benchmarking: writing quality tests, using table-driven tests, mock objects, and performance profiling.
• Working with Concurrency: advanced usage scenarios for goroutines, channels, synchronization primitives, and patterns for managing parallel tasks.
• Performance Optimization: how to avoid common pitfalls, memory management, allocations, and code profiling.
• Working with External APIs and Databases: best practices for integration, handling timeouts, retry mechanisms, and connection pools.

Who is this book for?

This book will be useful for:

• Developers transitioning to Go from other languages (Java, Python, C#).
• Go developers with 1+ years of experience who want to deepen their knowledge.
• Tech leads and architects who want to implement best practices in their team.
• Anyone who wants to write Go professionally and efficiently.

What will you learn?

After reading this book, you will be able to:

• Write code that is easy to read, test, and maintain.
• Design reliable and performant applications.
• Avoid common mistakes that even experienced developers make.
• Effectively use concurrency and multithreading.
