Use Cases of Dependency Injection Pattern
Below are the use cases of Dependency Injection Pattern:
- Modular Application Design:
- Dependency Injection is commonly used in modular application design, where classes and components are designed to be loosely coupled.
- By injecting dependencies externally, classes become more modular and easier to maintain, test, and extend.
- Unit Testing:
- DI facilitates easier unit testing by allowing dependencies to be replaced with mock objects or stubs during testing.
- This enables developers to isolate and test individual components of the system without having to instantiate complex dependencies.
- Integration with Frameworks:
- Dependency Injection is widely used in frameworks and libraries, such as Spring Framework (Java) and Angular (JavaScript), for managing object dependencies and configuring application components.
Dependency Injection vs Factory Pattern
In coding, there are special ways to organize our work called “design patterns.” Two important ones are Dependency Injection (DI) and the Factory Pattern. They help make our work easier by keeping things neat and separate. In this article, we will see the differences between them and, when to use each.
