Angular 2 - Instantiate (Http) Service Manually

Question

Is it possible to instantiate Http Service manually without having it to put as a constructor argument?

export class SimpleGridServer {
    private http: Http;
    constructor(public options: SimpleServerData) {
        http = new Http(.../* Argument here */);
    }
}

To instantiate this class.

var grid = new SimpleGridServer({/* options */});

I want to instantiate this class without having a dependency on Http service for my component that import SimpleGridServer. If this is possible, what is the drawback for this scenario?

You need to be in an Angular DI workflow to use Angular stuff.

You can get a handle to angular's injector directly:

import {ReflectiveInjector} from '@angular/core';
import {HTTP_PROVIDERS, Http, Headers} from "@angular/http";
const injector = ReflectiveInjector.resolveAndCreate([HTTP_PROVIDERS]);
const http = injector.get(Http);
