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.

Conditional statements and loops

In Go, there are two keywords for conditional statements—if, and switch. Let's take a practical look at each one of them.

The if statement

The if statement looks like this:

if <condition>{
}

So, let's assume we want to compare whether a value, x, is equal to 10. Here is what the syntax would look like:

if x == 10{
}

In Go, you can also execute some initialization in your if statement. Here is what this syntax would look like:

if x := getX(); x == 5{
}

Like other programming languages, an if statement is never complete without an else clause. Here is what an if else looks like in Go:

if x==5{
}else{
}

How about an else clause with a condition?

if x == 5{
}else if x >10{
}...
