Bridging the Gap between Legacy and Modern Systems: The Power of the Adapter Pattern
Introduction In the ever-evolving world of software, one constant is the need to integrate or work with legacy systems. Often, you’ll come across situations where you need to interact with old codebases, third-party libraries, or systems you cannot modify. This is where design patterns, specifically the Adapter pattern, come to the rescue. The Adapter pattern…

Singleton Design Pattern in Go: A Safe Approach to Global Variables
Introduction In the realm of software design, there is a widely shared belief that global variables can cause numerous issues, often sparking debates (or, depending on whom you ask, impassioned arguments). Over time, I have come to realize that the use of global variables tends to signify poor code quality and overall suboptimal design. They…

The Factory Design Pattern in Go: Simplifying Object Creation
Introduction One of the cornerstone patterns used in object-oriented programming is the Factory Pattern. It’s all about making the object creation process more intuitive and less complex. To illustrate this, let’s examine a provided Go code snippet and break down its essence. The Core Idea In the heart of the Factory Pattern is the creation…

Abstract Factory Design Pattern: A Practical Dive with Golang
Introduction In software engineering, designing with principles such as SOLID is crucial. The SOLID principle emphasizes Interface Segregation, which advocates for using multiple, client-specific interfaces. Building on this idea, the Abstract Factory design pattern becomes relevant as it encapsulates object creation, enabling a system to generate families of related objects without specifying their concrete classes.…
