Are SOLID principles overrated?

Video Description

In this video, we conclude our extensive exploration of SOLID principles in software design. We've covered what SOLID principles are, common violations, and how to refactor code to comply with these principles. We also discuss the increased complexity that comes with adhering to these principles and whether it’s always necessary. We'll revisit the basics of Object-Oriented Programming (OOP) to understand the foundation on which SOLID principles are built. Then, we’ll dive deep into each of the SOLID principles, questioning their practical application and exploring whether they should be considered absolute rules or flexible guidelines. Key topics covered include: Single Responsibility Principle (SRP): Does it really mean single responsibility, or could it be more about similar responsibilities? Open/Closed Principle (OCP): The challenges of making your code open for extension but closed for modification. Liskov Substitution Principle (LSP): Understanding substitutability beyond polymorphism and inheritance. Interface Segregation Principle (ISP): Balancing the creation of specific interfaces without overwhelming your code with too many. Dependency Inversion Principle (DIP): Differentiating between dependency inversion and dependency injection, and their roles in creating modular and flexible code. As we wrap up, we emphasize the importance of applying these principles pragmatically rather than dogmatically, ensuring that your code remains simple, flexible, and easy to maintain. #SoftwareDesign #SOLIDPrinciples #ObjectOrientedProgramming #CodingBestPractices #SoftwareEngineering #ProgrammingTips #OOP #CleanCode #CodeRefactoring #SoftwareDevelopment #TechTalk Follow me on Twitter: https://twitter.com/anilvdeshpande Links to other sources https://www.reddit.com/r/programming/comments/5qto27/why_every_element_of_solid_is_wrong/ https://softwareengineering.stackexchange.com/questions/447532/when-to-not-use-solid-principles https://dunnhq.com/posts/2021/solid-relevance/ The S.O.L.I.D.
