As a Java engineer in the web development industry for several years now, having heard multiple times that X is good because of SOLID principles or Y is bad because it breaks SOLID principles, and having to memorize the “good” ways to do everything before an interview etc, I find it harder and harder to do when I really start to dive into the real reason I’m doing something in a particular way.
One example is creating an interface for every goddamn class I make because of “loose coupling” when in reality none of these classes are ever going to have an alternative implementation.
Also the more I get into languages like Rust, the more these doubts are increasing and leading me to believe that most of it is just dogma that has gone far beyond its initial motivations and goals and is now just a mindless OOP circlejerk.
There are definitely occasions when these principles do make sense, especially in an OOP environment, and they can also make some design patterns really satisfying and easy.
What are your opinions on this?
But if the contract were an interface, for example, the compiler would enforce it on both sides, and you would get synchronous communication and common data format for free, and team A would know that they’d broken team B’s code because it wouldn’t pass CI and nothing drastic would happen in production.
At that scale, contracts are multiple interfaces, not just one. And C#/Java /whathaveyou interfaces are largely irrelevant, we’re talking way broader than this. Think protocol, like REST, RPC…
