Crafting focused, maintainable code: the power of single responsibility
In the hierarchy of software design, we have high-level architecture at the top, followed by components, modules, classes, and, finally, functions. The SOLID principles primarily operate at the module level, providing guidelines for creating well-structured, maintainable code. These module-level practices form the foundation for good architecture in general, including Clean Architecture. By applying SOLID principles, we can create loosely coupled, highly cohesive components that are easier to test, modify, and extend. These qualities are fundamental attributes of Clean Architecture.
Understanding single responsibility
The Single Responsibility Principle (SRP) states that each software module should have one and only one reason to change (https://blog.cleancoder.com/uncle-bob/2014/05/08/SingleReponsibilityPrinciple.html).
At first glance, the concept of single responsibility might seem straightforward...
