👉 Closure engineering is a design strategy in software development that focuses on creating robust and maintainable systems by ensuring that components or modules can operate independently while still being seamlessly integrated when needed. It involves designing interfaces and interactions that allow for a clear separation of concerns, enabling developers to modify or replace parts of the system without affecting others. This is achieved through techniques like defining clear contract specifications, using well-defined APIs, and implementing dependency injection to manage component relationships. Closure engineering aims to enhance system flexibility, scalability, and resilience by ensuring that components can be closed (or shut down) or reopened (or integrated) as needed, thus improving overall system reliability and adaptability to changing requirements.
