Body of Http.DELETE request in Angular2

Question

I\'m trying to talk to a somewhat RESTful API from an Angular 2 frontend.

To remove some item from a collection, I need to send some other data in addition to the re

Since the deprecation of RequestOptions, sending data as body in a DELETE request is not supported.

If you look at the definition of DELETE, it looks like this:

    delete(url: string, options?: {
      headers?: HttpHeaders | {
         [header: string]: string | string[];
        };
      observe?: 'body';
      params?: HttpParams | {
          [param: string]: string | string[];
         };
      reportProgress?: boolean;
      responseType?: 'json';
      withCredentials?: boolean;
     }): Observable;

You can send payload along with the DELETE request as part of the params in the options object as follows:

this.http.delete('http://testAPI:3000/stuff', { params: {
    data: yourData
     }).subscribe((data)=>. 
        {console.log(data)});

However, note that params only accept data as string or string[] so you will not be able to send your own interface data unless you stringify it.
