Leveraging Dependency Injection in Angular to Simplify HTTP Calls
When developing Angular applications, managing HTTP requests efficiently is a common challenge. To streamline this process, you might create a common class for making API calls, which can then be extended by other components. However, dependency injection (DI) in Angular can introduce complications, particularly when extending classes that require injected services. In this post, we'll walk through a scenario where we have a common class for making HTTP calls and explore how to use Angular's new inject() function to simplify the DI process. Creating a Common Class for HTTP Calls First, let's create a common class, HTTPClass , which will manage our HTTP requests. This class will use Angular's HttpClient service to make GET and POST requests. Instead of using the constructor to inject HttpClient, we'll use the inject() function directly in the class. import { HttpClient } from ...
