DIP

Let’s discuss SOLID one more time. If your work is somehow related to software development or you are interested in programming, chances are you’ve heard this famous (or infamous) acronym before. There are countless blog posts, articles, and YouTube videos about it. It’s probably one of the most discussed acronyms in the world of software. But in this post, I’d like to reflect specifically on the last (but not least) letter, D, which refers to the Dependency Inversion Principle, or DIP. Why is this principle important for writing maintainable code? Is it important at all? Why bother? To answer these questions, let’s try to invert a FastAPI endpoint.
