Facade Pattern: A Beginner’s How-To for Simplified Code

In this article I'll be going over one of my most used design patterns called the facade (or fa├žade), and explaining why I like to use it. As with all things I share information about, it's important to remain pragmatic as software engineers. With that said, this article is not to persuade you to use this pattern exclusively or that there are not alternatives. Instead, I'd like to arm you with another design pattern tool in your figurative coding toolbox. The more tools you have available, the better prepared you are to go build awesome stuff. What We're Trying to Achieve With a Facade When I am developing software, whether it is personally, professionally, or as someone that is influencing the direction of software I am not directly coding myself, I encourage a focus on flexibility in software.

After all, it's easier to just rewrite things from scratch instead of trying to make a huge design change part way through, right? In any mature software project, it's often the case where you'll get to a point where your code base in its current state cannot properly sustain large changes going forward. It's not really anyone's fault--it's totally natural. It's impossible to plan absolutely everything that comes up, so it's probable that at some point at least part of your software project will face refactoring. In my real life example, I was tasked with refactoring a software project that has a single owner. I'm close…
