When building a Go application, logging is an essential part of the development process. The Go standard library provides a basic logging package, but it doesn’t offer many advanced features. Fortunately, there are many third-party logging libraries available that provide more features and flexibility. However, using different logging libraries throughout…

Go is a statically typed language that offers a lot of safety and performance. One of the benefits of static typing is that the compiler can catch errors at compile time, preventing them from happening at runtime. In Go, methods are defined on structs or types using the syntax func…

The Adapter design pattern is used when we want to connect two incompatible interfaces or classes so that they can work together. It’s especially useful when we have a legacy system or third-party library that we need to integrate with, but it doesn’t use the same interface as the rest of our code. In Go, we can implement the Adapter pattern using interfaces, structs, and composition. We can create an interface that defines the methods we need to work with, and then create an adapter struct that implements that interface and wraps the incompatible interface or class.

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a highly scalable and flexible environment for deploying and managing containerized workloads. The Kubernetes architecture consists of several components that work together to provide a stable and scalable environment for containerized…

Testing is a crucial aspect of software development, especially for web applications. In Go, testing is built into the language and provides powerful tools for writing and running tests. In this article we will explore the flow of a Go web application, how to write unit tests for each layer…

When running a containerized service on AWS, it is common to have multiple containers running behind a load balancer. These containers need to communicate with each other, and a common approach to achieve this is through service discovery. AWS Service Discovery is a managed service that makes it easy to…

Go makes it easy to create and use packages. In this tutorial, we’ll create a simple package that uses a third-party dependency and learn how to use it in a new project. Prerequisites Before we get started, make sure you have the following: Go installed on your machine Basic knowledge of…

The Facade Design Pattern is a structural pattern that provides a simplified interface to a complex system of classes, libraries, or frameworks. It encapsulates the complexity of the system behind a single interface, making it easier to use and understand for the client code. …

The Strategy pattern is a popular design pattern used in object-oriented programming to encapsulate algorithms or behaviours in interchangeable components. It promotes flexibility, extensibility, and maintainability by decoupling the implementation of an algorithm from the code that uses it. In this article, we’ll explore how the Strategy pattern can be…
