Let's Go! Learn to Build Professional Web Applications With Golang

Go is a great language for building web applications. But teaching yourself from blog posts and the standard-library documentation can often leave you with more questions than answers.

You might be wondering:

Let’s Go answers these questions for you — and a whole lot more.

The book guides you through the start-to-finish build of a real-world application, so you'll gain all the knowledge, understanding and confidence needed to create production-quality applications with Go.

What Readers Are Saying…

“I feel like this is the best programming book I've ever read. I came in with a basic understanding of golang relative to web development and this book clearly broke down all the essentials you need to get up to speed with the language in a web dev context.”

— Michael Deigl, Toronto

“I like that the book follows along a practical example. Most book examples relate to one chapter which is rather bad for learning a new language. With an evolving example it is much easier to follow along.”

— Daniel Reichenbach, Berlin

“I really liked the advice on how to structure a project. I'm now refactoring my first Golang project to use your advice, which will make it easier to read and maintain.”

— Paul Bradbury, Cumbria

“I liked that the book was clear and that it reinforced what I already knew, but got a second opinion. Really glad it addressed the security issues in some of the libs.”

— Lucas Caballero, Colorado

Foreword

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 the book is to help you learn by doing. Together we'll walk through the start-to-finish build of a web application — from structuring your workspace, through to session management, authenticating users and securing your server.

Building a complete web application in this way has a number of benefits. It helps put the things you're learning into context, it demonstrates how different parts of your codebase link together, and it forces us to work through the edge-cases and difficulties that come up when writing software in real-life. In essence, you'll learn more that you would by just reading Go's (great) documentation or standalone blog posts.

By the end of the book you’ll have the understanding — and confidence — to build your own production-quality web applications with Golang.

Although you can read the book cover-to-cover, it's designed specifically so you can follow along with the project build yourself.

Break out your text editor, and happy coding!

Hey, I’m Alex Edwards, a full-stack web developer. I began working with Golang 5 years ago in 2013, and have been teaching people and writing about the language for nearly as long.

I’ve used Go to build a variety of production applications, from simple websites (including the one you’re reading now) to high-frequency trading systems. I also work on a number of open source Go packages, including the popular session management system SCS.

I live near Innsbruck, Austria. I post regularly on my blog and you can follow me on Instagram, Twitter and Github.
