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

HTTP clients are used to interact with web servers. They are used to send different types of requests to a server (for example, GET or POST requests) and then react to the response returned by the server. A web browser is a type of HTTP client that will send a GET request to a web server and display the HTML data it returns. In Go, you created your own HTTP client and did the same thing, sending a GET request to https://www.google.com and then logging the response returned by the server. You also learned about the components of a URL and that you can control what you request from a server by changing the URL.

There is also more to web servers than simply requesting HTML data. You learned that they can return structured data in the form of JSON, which can be parsed and used in your code. Data can also be sent to a server using POST requests, allowing you to send form data to a server. However, the data sent to a server isn't limited to just form data: you can also upload...
