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

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.

Let's Go book cover

What You’ll Learn…

  1. All the fundamentals — How to start a server, create handlers, send responses, route requests and serve static files.
  2. Structure and organization — How to create an idiomatic and scalable structure for your web application.
  3. Managing configuration — How to use command-line flags and dependency injection to manage your application settings.
  4. SQL databases — How to design a database model, set up a connection pool, and execute statements and queries.
  5. HTML templating — How to display dynamic data, create your own custom functions and handle runtime errors.
  6. RESTful routing — How to create a modern request routing structure that follows the principles of REST.
  7. Session management — How to use and configure sessions to persist data between requests.
  8. Processing and validating forms — How to implement a user-friendly pattern for processing forms and displaying errors.
  9. Middleware — How to create your own middleware and use it to perform common actions (including logging requests).
  10. Using HTTPS — How to correctly setup a HTTPS server and configure it for improved performance and security.
  11. Authentication and authorization — How to safely encrypt user passwords and add signup, login and logout functionality.
  12. Prevent common vulnerabilities — How to prevent SQL injection, CSRF, XSS, clickjacking and slow-client attacks.
  13. And most importantly… How to put it together in a fully-functioning application!

What Readers Are Saying…

The book is brilliant, I’m learning so much from it. It’s definitely the best book I’ve read on developing a non-trivial web app with Go.

John Zanchetta

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

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

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.

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 Go.

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 nearly 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. You can follow me on Instagram, Twitter, Github and on my blog.
