The Go Workshop

By: Delio D'Anna, Andrew Hayes, Sam Hennessy, Jeremy Leasor, Gobin Sougrakpam, Dániel Szabó

Overview of this book

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.

Go tools are invaluable to a programmer when they're writing code. In this chapter, you learned about go build and how to compile your code into executables. Then, you learned how consistent neat code is important when working on a project and how you can use gofmt to automatically neaten up the code for you. This can be further improved with goimports, which can remove unnecessary imports for better security and automatically add imports you may have forgotten to add yourself.

After, you looked at go vet and how it can be used to help you find any mistakes that the compiler may have missed. You also learned how to use the Go race detector to find race conditions hidden in your code. Then, you learned how to generate documentation for your code, which makes for easier collaboration when working on larger projects. Finally, you looked at downloading third-party packages using the go get tool, which allows you to make use of numerous Go packages that are available online...
