(LSD Session | 6th Nov 2024) Mastering the Single Responsibility Principle (SRP)
Our LSD (Leetcode & Software Development) sessions at Polygon Technology are dedicated to enhancing problem-solving skills through Leetcode exercises and delving into various software development principles. These sessions serve as a collaborative space for our team to tackle complex coding challenges and explore best practices that refine our craft.
This LSD session, led by our own Sudipta Karmakar, took a deep dive into the Single Responsibility Principle (SRP) – a key component of clean code and object-oriented programming (OOP). SRP, the "S" in SOLID principles, reinforces the importance of clear, singular responsibilities for every class, function, and module, ultimately making our codebase more adaptable, modular, and maintainable. ??
?? Objective:
We focused on advancing our coding practices by structuring our code into clear, focused components to reduce dependencies and enhance flexibility.
?? Applying SRP in Practice:
Responsibility Breakdown: Isolating tasks like data management, UI rendering, and business logic to create testable, modular code.
Decomposing Large Classes: Transforming complex “God classes” into focused, purpose-specific classes, such as Order Service and Payment Service in an e-commerce app.
Method-Level Focus: Developing each method for a single task, increasing reusability and testability.
Interface Use: Using distinct interfaces to maintain single responsibilities, bringing clarity across modules.
?? The Impact:
Readability & Maintainability: Simplified code that’s easier to understand, update, and debug. ??
Scalability: Future-proof code that adapts seamlessly as our requirements grow. ??
?? Challenges & Next Steps:
While SRP introduces more classes, it’s a worthwhile investment, keeping each component focused and ready to scale with ease. Thanks to Sudipta Karmakar for the insightful session and to the team for engaging in real-world discussions on achieving balanced granularity. ??
Proud to keep strengthening our culture of clean, modular code at Polygon Technology! ?? #SRP #CleanCode #TechSession #PolygonTechnology
