The Go Workshop will take the pain out of learning the Go programming language (also known as Golang). It is designed to teach you to be productive in building real-world software. Presented in an engaging, hands-on way, this book focuses on the features of Go that are used by professionals in their everyday work.Each concept is broken down, clearly explained, and followed up with activities to test your knowledge and build your practical skills.Your first steps will involve mastering Go syntax, working with variables and operators, and using core and complex types to hold data. Moving ahead, you will build your understanding of programming logic and implement Go algorithms to construct useful functions.As you progress, you''ll discover how to handle errors, debug code to troubleshoot your applications, and implement polymorphism using interfaces. The later chapters will then teach you how to manage files, connect to a database, work with HTTP servers and REST APIs, and make use of concurrent programming.Throughout this Workshop, you''ll work on a series of mini projects, including a shopping cart, a loan calculator, a working hours tracker, a web page counter, a code checker, and a user authentication system.By the end of this book, you''ll have the knowledge and confidence to tackle your own ambitious projects with Go.

Who this book is for

The Go Workshop is designed for anyone who is new to Go. Whether you''re beginning your journey as an aspiring developer, or are experienced with another programming language and want to branch out to something new, this book will get you on the right track. No prior programming experience is necessary.

Learn to architect, implement, and scale robust distributed systems. This practical guide emphasizes real-world applications of domain-driven design, hexagonal architecture, and reactive systems, all within the context of the Go programming language and the NATS messaging system.The book begins with foundational concepts and gradually progresses to advanced architectural patterns. You will first explore synchronous and asynchronous communication mechanisms before learning to design and implement individual services that are resilient, scalable, and responsive. From there, the focus expands to broader system architecture. You will learn to create software aligned with real-world business processes using domain-driven design. Finally, you’ll explore hexagonal architecture and reactive systems to learn how to design modular, resilient systems capable of handling concurrency and asynchronous processing efficiently.Today, the adoption of distributed systems is accelerating, necessitating a nuanced understanding of distributed architecture principles. Through clear methodologies, architectural discussions, practical examples, and real-world scenarios, you will be ready to build distributed systems with confidence.What You Will Learn:Understand distributed systems basics, including communication protocols like req/rep, push/pull, and pub/sub.Grasp microservice internals such as service discovery, load balancing, and fault tolerance.Apply the concepts of domain-driven design, hexagonal architecture, and reactive systems practically.Build robust distributed systems using Go and NATS messaging system using real-world examples.Explore the architecture of interconnected components to design modular, maintainable systems.Understand handling high concurrency and adapt to evolving demands.Who This Book is for:Software developers seeking practical guidance on building scalable distributed systems with GO and NATS, regardless of their level of experience with the Go programming language. Also suitable for aspiring architects and system designers seeking to deepen their understanding of architectural patterns and implementation.
