I was recently restructuring one of my early Go side projects. As I was changing the project layout, I was reminded there are many recommendations out there but no set standard for structuring Golang projects. In other programming languages such as Java, there is a typical project layout that most…

Concurrency is such a foundational capability of the Go language that it is effortless to write code that leverages multiple goroutines, sometimes without even knowing. As an example, if you’ve ever used the net/http package to create a web service, you’ve used goroutines. To handle incoming HTTP traffic, the HTTP…

Let’s face it, even with all the changes in how we run systems at scale, shell scripts are still a go-to tool in the DevOps & Site Reliability Engineers toolbelt. The simplicity of BASH has kept it relevant, but even though we rely on these shell scripts daily, they are…

While most systems these days integrate over gRPC or HTTP, quite a few applications still speak custom protocols. And many of these custom protocols don't have handy packages like net/http to manage all of the TCP connection creation and management. Today's article is for anyone working directly with TCP connections…

Working with TCP servers is a great way to become familiar with low-level network communications. When writing applications that communicate directly over TCP sockets a multitude of socket management steps are required. Actions that you typically don’t have to take for a typical HTTP-based application. Sometimes, those extra management steps…

Recently I wanted to revamp one of my side projects go-quick. This project is a boilerplate web application meant to be a starting point for Go apps. Previously, I wrote a custom config package within the project to pull configuration from Environment Variables as per the 12 Factor Apps manifest…

When I was learning Golang, one of the concepts that took me the most time to grasp was Interfaces. Golang’s Interfaces are a great way to make modular and testable code. But they can also be a bit confusing at first glance. One of the best ways I’ve found to…
