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.

In the previous chapter, we learned about Go tools such as fmt, vet, and race, which are designed to help you with your code development. Let's now look at how to secure your code by looking at examples of common vulnerabilities. We'll also look at the packages in the standard library that can help you to store your data securely.

Security cannot be an afterthought. It should be part of your code kata, something that you practice every day. Most vulnerabilities in applications stem from the developer not knowing about potential security attacks and from not having a security review of the application before it gets deployed.

If you look at any websites dealing with sensitive data, for example, banking websites, they will have basic security in place, such as the use of a signed SSL certificate. It is always better to design your application with security in mind than to add security layers later, so as to avoid refactoring or redesigning your application...
