One way to do it would be to make class with all the properties that you need and configure as a singleton when you bootstrap the application.

Service:

import {Injectable} from 'angular2/angular2';


@Injectable()
export class Config {

  constructor() {}

  public get USERID(): string {
      return "XCAMPLISHIOUS";
  }

}

Bootstraping:

import {bootstrap} from 'angular2/angular2';
import {TaciIlieApp} from './app/taci-ilie';
import {Config} from './app/services/config/config';

bootstrap(TaciIlieApp, [Config]); // configuring the Config provider here will ensure a single instance is created

Usage:

import {Component, Inject} from 'angular2/angular2';

import {Config} from '../../services/config/config';

@Component({
  selector: 'game',
  templateUrl: 'app/components/game/game.html',
  styleUrls: ['app/components/game/game.css'],
  providers: [],
  directives: [],
})
export class Game {


  constructor(private config: Config) {
      console.log(this.config.USERID);
  }
