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.

Summary

In this chapter, you've been introduced to the server side of web programming. You've learned how to accept requests from HTTP clients and respond in an appropriate manner. You've learned how to separate the possible requests into different areas of an HTTP server via paths and sub-paths. For this, you used a simple routing mechanism with the standard Go HTTP package. You've seen how to return your response in order to suit different consumers: JSON responses for synthetic clients, and HTML pages for human access. You've seen how to use templates in order to format your plain text and HTML messages, using the standard templating package. You've learned how to serve and use static resources, serving them directly through a default file server or through a template object. You've also learned what a REST service is, and although we have not built one together, you have all the knowledge necessary to create one, provided you follow the description...
