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:

• Where can I see a concrete example of a real-world web application?
• How is it best to structure and organize my code?
• How do I make sure I’m not making any mistakes when it comes to security?
• How do I use modules to manage and version control dependencies?
• And how do I effectively test my web application?
• 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 you need to create production-ready applications with Go.
