HttpClient doesn't make http network request

Question

I am using HttpClient and it doesn't make a network request, there are no errors so I don't know what is wrong.

  postFile(file: FileUpload) {
    console.log('posting file');
    return this.http.post(this.apiRoot + '/api/file', file, this.httpOptions)
      .pipe(
        catchError(this.handleError('postFile', []))
      );
  }

app.module

import { HttpClientModule } from '@angular/common/http';
// ...
imports: [
    HttpClientModule
  ],

You are missing the subscribe().

return this.http.post(this.apiRoot + '/api/file', file, this.httpOptions)
   .pipe(
      catchError(this.handleError('postFile', []))
   )
   .subscribe();

or in your component call the method like this:

this.postFile(file).subscribe();
