Learn why grouping code by feature instead of technical layers (controllers, services, repositories) improves scalability, maintainability, and developer experience in modern software architecture.
Learn the Interface Segregation Principle (ISP) with real-world TypeScript examples. Identify bad interfaces, refactor for flexibility, and build scalable, decoupled, and testable applications with ISP from SOLID principles.
An Orchestrator is a class (or module) responsible for coordinating multiple responsibilities by delegating tasks to other services or components. It does not implement logic itself — it uses others to get the job done.
Learn the Interface Segregation Principle (ISP) with real-world TypeScript examples. Identify bad interfaces, refactor for flexibility, and build scalable, decoupled, and testable applications with ISP from SOLID principles.
Learn the Open/Closed Principle with advanced TypeScript examples. Discover how to write extensible code, avoid changes to core logic, and detect when to apply OCP in real-world scenarios.
