Modularity in software development refers to dividing an application into distinct and self-contained units that can be developed, tested, and maintained independently. In Spring Boot, modularization ensures clean separation of concerns, scalability, and easier management of code.
Why Modularize a Spring Boot Application?
- Separation of Concerns: Different features or business logic are isolated, making them easier to understand and manage.
- Reusability: Modules can be reused across multiple applications or services.
- Scalability: New features can be added as separate modules without affecting existing ones.
- Testability: Isolated modules make unit and integration testing more straightforward.
Key Concepts in Modular Design
- Base Module: The core module that contains common configurations and utilities.
- Feature Modules: Modules that encapsulate specific functionalities or features.
- API Module: Exposes REST endpoints to interact with feature modules.
- Dependency Management: Manages inter-module dependencies effectively.
