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.

Getting Some Style

Up to now, you've seen how to serve one static page and you might consider serving a few pages with the same method, maybe creating a handler struct with the name of the file to serve as an attribute. This might be impractical for large numbers of pages, although, in some cases, it is necessary. A web page, however, does not include just HTML code, but also images and styles, and some frontend code. It is not within the scope of this book to teach how to build HTML pages, and even less how to write JavaScript code or CSS style sheets, but you need to know how to serve these documents as we use a small CSS file to build our example. Serving static files and putting templates in different files, or generally using external resources, is a good way to separate concerns on our projects, and makes our projects more manageable and maintainable, so you should try to follow this approach in all your projects.

In order to add a style sheet to your HTML pages, you...
