But readers following these examples realize, only after years, how counterproductive it is to have monolithic chunks of code in their project.

They are not meant to teach software design. Examples like “let’s say we have this ORM X for our models, templating engine Y for our views and we will have controllers to manage it all” achieve nothing other than humongous controllers.Īlthough in defense of these books, the examples are meant to demonstrate the ease at which you can get started with their framework.
But they also end up providing bad advice for beginners. These examples try to show what the framework has to offer. Model Is EverythingĪlmost every book about some new MVC (MVP, MVVM, or other M**) framework is littered with examples of bad code. Writing great code is an art, but some principles can always help give your development work the direction it needs to head towards to produce robust and maintainable software. In this article, I will discuss how the Single Responsibility Principle and some techniques that revolve around it can give your code this very quality. This is something that should be considered a fundamental quality of software engineering and design.
We may not need to write great code when we are trying to build a prototype, a proof of concept or a minimum viable product, but in all other cases we should always write code that is maintainable. Any code which is not maintainable and cannot adapt to changing requirements with relative ease is code just waiting to become obsolete. Proper indentation, neat variable names, 100% test coverage, and so on can only take you so far. Regardless of what we consider to be great code, it always requires one simple quality: the code must be maintainable.
