Interfaces in Go

Interfaces in Go are going to be a foreign concept to many developers. In this series we explore what interfaces are, why they are useful in a dynamically typed language, and how the subtle differences from other languages have a big impact on how interfaces are used effectively in Go.

Concurrency Patterns in Go

Structuring Web Applications in Go

In this series we explore how you might structure an application written in Go. We start by examining why it is so hard for everyone to just agree on a universal structure, and then dive into a few various options looking at the pros and cons of each. By the end you should have a solid understanding of how to go about deciding what structure is best for your context when you start your next application in Go. We will mostly focus on web applications, but the overall message applies for almost all apps written in Go.
