import { APIModule, CachedAPIService } from '@dlarsson-se/cached-api;

@NgModule({
  imports: [ APIModule.forRoot() ]  // If it works, or
  ...
  imports: [ APIModule ],           // If it doesn't
  providers: [ CachedAPIService ]
})
export class AppModule {
  constructor(public apiService: CachedAPIService) {

    /* If the requests should contain Authorization: Bearer TOKEN */
    apiService.setToken('YOUR_TOKEN');                                 

    /* Default URL for TestData objects. */
    apiService.addURL(TestData, "http://localhost/testdata");         

    /* Custom URL for the find command. */ 
    apiService.addURL(TestData, "http://localhost/testdatas", "find"); 
  }
}

app.component.ts (without APIComponent inheritance)

import { CachedAPIService } from '@dlarsson-se/cached-api';

export class AppComponent {
  constructor(private apiService: CachedAPIService) {
    let id = 1;

    /* Get By ID */
    apiService.get(TestData, id)
      .subscribe((value) => {
        /* Do something with the reply. */
      }, (error) => {
        /* Error handling. */
      })

    /* Find */
    apiService.find(TestData)
      .subscribe((values) => {
        /* Do something with the reply. */
      }, (error) => {
        /* Error handling. */
      })
  }
}

app.component.ts (with APIComponent inheritance)

import { APIComponent, CachedAPIService } from '@dlarsson-se/cached-api';

export class AppComponent extends APIComponent {
  constructor(public apiService: CachedAPIService) {
    super(apiService);
    let id = 1;
    
    /* get with mandatory supplied id. */
    let p1 = this.getAsync(TestData, id)

    /* find with optional querystring. */
    let p2 = this.findAsync(TestData, "YOUR_QUERY_HERE") 

    /* Handle all promises. */
    Promise
      .all([p1, p2])
      .then((values) => {
        /* Do something with the reply. */
      })
      .catch((error) => {
        /* Error handling. */
      }) 
  }
}
