Let’s Go is a clear, concise and easy-to-follow guide to web development with Go.
It packs in everything you need to know about best practices, project structure and practical code patterns — without skimping on important details and explanations.
“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 Ops & test engineer / France
Go is a great language for building web applications. But teaching yourself from blog posts and the standard library documentation can be a big time-sink and leave you with more questions than answers.
You might be wondering things like:
Let’s Go answers these questions for you — and a whole lot more — helping you get up to speed quickly and saving you months of research and experimentation.
The book walks through the start-to-finish build of a complete working application, helping you to learn by doing. You’ll get practical experience implementing common real-life code patterns, the topics that you’re learning about are put in context, and you’ll end up with a well-structured codebase that you can adapt for your own future work.
By the end of the book, you’ll have all the knowledge and confidence that you need to build your own professional, production ready, web applications.
So grab your copy, break out your text editor, and happy coding!
“I came to Go from Python/Flask and I was getting frustrated by how long it was taking me to reimplement some of the coding patterns in Go on my own. Your book saved me about six months of work and now I feel like I’m finally ready to build a production system in Go.”Andres Morey Lead developer / New York

Hey, I’m Alex Edwards, a full-stack web developer and author of Let’s Go and Let’s Go Further. I live near Innsbruck, Austria.
I’ve been working with Go for over 10 years, building production applications for commercial clients and myself (including the website that you’re reading now!) and helping people all around the world improve their Go skills.

“The practical advice about the Go ecosystem and best practices has saved me an enormous amount of time, guesswork and frustration. Thanks!”Tushar Samant Web developer / Chicago
Yep! The book deliberately takes a “learn as you code” approach, starting slowly with the basics of building a web application and gradually adding additional features and functionality. So long as you have a basic understanding of the Go syntax, you shouldn’t have trouble following along — especially if you’ve built web applications in other languages before.
If you don’t get anything from the book, then I don’t want your money. Just reply to your email receipt within 30 days and I’ll issue a full refund.
Let’s Go teaches you to build web applications using the Go standard library (rather than a specific framework like Buffalo, Echo or Gin). A few small external packages are used where it makes sense for security reasons and to reduce complexity.

The source code is included in a zip file as part of the Professional Package download. You can open it on your local machine and start exploring it right away.
Updated versions of the book will be emailed to you at the address you provide during checkout. These are usually sent out once every 6 months, to coincide with new major releases of the Go language. You can unsubscribe from the updates at any time.
You can buy online by PayPal, credit card or debit card over a secure encrypted connection. After purchase you’ll immediately be given a download link for the book, and a email confirmation will also be sent to you.
Yes, in your email receipt there is a link that you can use to generate an invoice with a specific name and billing address. Please see these instructions.
In the Professional Package, at the end of the book there are 6 exercises which extend the application build. Each exercise is broken down into high-level steps for you to work through, and there are suggested answers for each step. The exercises are designed to use the principles and patterns covered earlier in the book, so they’re a good way to test yourself and check your understanding.
Any other questions? Email me at alex@alexedwards.net and I’ll be happy to help.
