Services
Services are reusable pieces of code that provide specific functionality or perform tasks across your Angular application. They are typically used for tasks such as fetching data from a server, sharing data between components, or performing business logic. Services are a key part of Angular’s dependency injection system, which allows you to inject dependencies into your components, directives, and other services.
By encapsulating common functionality in services, you can keep your code DRY (Don’t Repeat Yourself) and make it easier to maintain and test.
Syntax:
import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root'
})
export class ExampleService {
getMessage() {
return 'Hello from the service!';
}
}
