Usage

Example:

import { Injectable } from '@angular/core';
import { Response, Http, Headers } from '@angular/http';
import { RESTService, HttpInterceptorService } from '@covalent/http-deprec';

@Injectable()
export class CustomRESTService extends RESTService<any> {

  constructor(private _http: Http /* or HttpInterceptorService */) {
    super(_http, {
      baseUrl: 'www.api.com',
      path: '/path/to/endpoint',
      headers: new Headers(),
      dynamicHeaders: () => new Headers(),
      transform: (res: Response): any => res.json(),
    });
  }
}

Note: the constructor takes any object that implements the methods in [IHttp] interface. This can be the @angular [Http] service, the covalent [HttpInterceptorService] or a custom service.

export interface IHttp {
  delete: (url: string, options?: RequestOptionsArgs) => Observable<Response>;
  get: (url: string, options?: RequestOptionsArgs) => Observable<Response>;
  head: (url: string, options?: RequestOptionsArgs) => Observable<Response>;
  patch: (url: string, body: any, options?: RequestOptionsArgs) => Observable<Response>;
  post: (url: string, body: any, options?: RequestOptionsArgs) => Observable<Response>;
  put: (url: string, body: any, options?: RequestOptionsArgs) => Observable<Response>;
  request: (url: string | Request, options: RequestOptionsArgs) => Observable<Response>;
}
