Benefits of Dependency Injection in Angular
- Modularity and Encapsulation: Dependency Injection helps in modular development by allowing components and services to declare their dependencies explicitly. It promotes encapsulation by decoupling components from the concrete implementations of their dependencies.
- Testability: Dependency Injection provides unit testing by making it easy to replace dependencies with mock objects or stubs during testing. Components and services can be tested in isolation, leading to more reliable and maintainable tests.
- Reusability and Maintainability: Dependency Injection promotes code reuse by enabling components and services to be easily composed and reused across different parts of the application. It improves maintainability by reducing code duplication and making it easier to understand and refactor code.
Angular Dependency Injection
Angular is an open-source framework for building web modern web applications. One of the key principles of Angular is dependency injection. Dependency Injection is one of the widely used techniques in application programming. It is included in almost every framework. In this article, we will learn about Dependency Injection and how to perform Dependency Injection in Angular.
