What is the method for generating a dynamic instance of an Angular service?

Struggling to figure out how to create angular services dynamically. Need help understanding DI and working with the http service.

import { HttpClient } from '@angular/common/http';

export class DynamicService {
  constructor(private http: HttpClient) {}

  fetchData() {
    return this.http.get('/data');
  }
}

let dynamicService = new DynamicService(HttpClient);
// encountering issues here.

Answer №1

To utilize the BaseService in your project, follow these steps:

@Injectable({
  providedIn: 'root'
})

Next, make sure to include the following code snippet between your import statement and the declaration of your BaseService class:

export class MyOtherClass {
    constructor(private baseClass: BaseClass) { }

    someMethod(): string{
        return baseClass.get();
    }
}

By utilizing Angular DI in this manner, a new instance of your Http Client will be provided by Angular when creating an instance of the BaseService. The @Injectable registration informs Angular DI on how to handle this injection process seamlessly.
