Implementing services with HTTP methods
To demonstrate the implementation of each approach, let’s go through the steps to create a new Angular application and implement the different approaches one by one.
Step 1: Create a new Angular application
ng new http-demo

}
Step 2: Import required Modules
Since we’ll be working with HTTP requests, we need to install to import modules related to HttpClient package, which provides the HttpClient’s functionalities. inside app.component.ts add below code
//app.component.ts
@Component({
selector: 'app-root',
standalone: true,
imports: [RouterOutlet, JsonPipe, CommonModule, HttpClientModule],
templateUrl: './app.component.html',
styleUrl: './app.component.css'
})
How to use services with HTTP methods in Angular v17?
In Angular 17, services play an important role in managing HTTP requests to backend servers. By encapsulating HTTP logic within services, you can maintain clean, modular, and testable code. In this article, we’ll explore how to use services to handle HTTP requests effectively in Angular 17 applications.
