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.

This chapter made you efficient in interacting with SQL databases. You learned how to create, delete, and manipulate database tables. You have also become aware of all the different types of databases Go is suited to interact with. As this chapter was made with the PostgreSQL engine in mind, you should familiarize yourself with its Go module too. With this knowledge, you will now be able to take your own steps in the realm of database programming with the Go language and be self-sufficient in the sense that you know where to look for solutions to problems and for extra knowledge. The most common use case for this knowledge is when you must build automated reporting apps that pull data from a database and report it as an email. The other use case is when you have an automated app for pushing data to the database server that processes a CSV file or an XML file. This really depends on the situation you are in.

In the next chapter, you will learn how to interact with web interfaces...
