Hands-On Full Stack Development with Go

By: Mina Andrawos

Overview of this book

The Go programming language has been rapidly adopted by developers for building web applications. With its impressive performance and ease of development, Go enjoys the support of a wide variety of open source frameworks, for building scalable and high-performant web services and apps. Hands-On Full Stack Development with Go is a comprehensive guide that covers all aspects of full stack development with Go. This clearly written, example-rich book begins with a practical exposure to Go development and moves on to build a frontend with the popular React framework. From there, you will build RESTful web APIs utilizing the Gin framework. After that, we will dive deeper into important software backend concepts, such as connecting to the database via an ORM, designing routes for your services, securing your services, and even charging credit cards via the popular Stripe API. We will also cover how to test, and benchmark your applications efficiently in a production environment. In the concluding chapters, we will cover isomorphic developments in pure Go by learning about GopherJS. As you progress through the book, you'll gradually build a musical instrument online store application from scratch. By the end of the book, you will be confident in taking on full stack web applications in Go.

Packages, variables, data types, and pointers

Packages, variables, data types, and pointers represent the most basic building blocks of the Go language. In this section, we'll cover them one by one from a practical point of view.

Packages

Any Go program consists of one or more packages. Each package is basically a folder, which contains one or more Go files. Every single Go code file you write must belong to a package. Package folders are found inside the src folder of your Go workspace.

When you write Go code, you declare your package name at the very top of your Go file. Here is what this looks like in code:

package mypackage

Here, mypackage is the name of the package that my Go file belongs to. It's idiomatic...
