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.

Database API and Drivers

In order to work with databases, there is something called the "pure" Go approach, which means Go has an API that allows you to use different drivers to connect to databases. The API comes from the database/sql package, and the drivers can be of two types. There is native support for a wide variety of drivers, which can be found on the official GitHub page (https://packt.live/2LMzcC4), and there are third-party drivers that need additional packages to function, such as the SQLlite3 package, which requires you to have GCC installed because it is a pure C implementation.

Note

GCC is a compiler system produced by the GNU Project. It takes your source code and translates it to machine code so that your computer can run the application.

Here is a list of a couple of drivers:
