Let’s Go teaches you step-by-step how to create fast, secure and maintainable web applications using the fantastic programming language Go. The idea behind this book is to help you learn by doing. Together we’ll walk through the start-to-finish building of a web application — from structuring your workspace through to session management, authenticating users, securing your server and testing your application. By the end of the book you’ll have the understanding and confidence to build your own production-ready web applications with Go. The information in this book is correct for the latest major release of Go (version 1.24), and you should install this if you’d like to code-along with the application build. This book is designed for people who are new to Go, but you’ll probably find it more enjoyable if you have a general understanding of Go’s syntax first. If you find yourself struggling with the syntax, the Little Book of Go by Karl Seguin is a fantastic tutorial, or if you want something more interactive I recommend running through the Tour of Go. I’ve also assumed that you’ve got a (very) basic understanding of HTML CSS and SQL, and some familiarity with using your terminal (or command line for Windows users). If you’ve built a web application in any other language before — whether it’s Ruby, Python, PHP or C# — then this book should be a good fit for you.
