Answer 1

In angular 2 you need to make the angular injector aware of your service. To do this you need to mark the service as Injectable.

HttpService

import {Injectable} from 'angular2/angular2';

@Injectable()
export class HttpService{
    ...
}

CurrentBlog

import {HttpService} from 'scripts/httpService';
import {Inject} from 'angular2/core';

export class CurrentBlog{

    constructor(public httpService:HttpService){}
}
