Mastering Microservices with Java - Third Edition

Services and dependency injection (DI)

You don't want to keep data and logic in the component, especially if data is used across multiple components, such as logged-in user details. You can delegate such tasks to Angular services. Angular services increase the modularity and reusability of the code. Angular services are written as classes with the @Injectable decorator. You can look at Angular services as similar to service classes that are created in Spring microservices, where Controllers delegate the data and logic processing to service classes.

Angular uses metadata defined in the @Injectable decorator to inject services inside components as dependencies. This is how services and DI work hand in hand. We will learn more about Angular ...
