1Here is the simplest solution w/o Service nor Observer:
2
3Put the global variables in a file an export them.
4
5//
6// ===== File globals.ts    
7//
8'use strict';
9
10export const sep='/';
11export const version: string="22.2.2";    
12To use globals in another file use an import statement: import * as myGlobals from 'globals';
13
14Example:
15
16// 
17// ===== File heroes.component.ts    
18//
19import {Component, OnInit} from 'angular2/core';
20import {Router} from 'angular2/router';
21import {HeroService} from './hero.service';
22import {HeroDetailComponent} from './hero-detail.component';
23import {Hero} from './hero';
24import * as myGlobals from 'globals'; //<==== this one (**Updated**)
25
26export class HeroesComponent implements OnInit {
27    public heroes: Hero[];
28    public selectedHero: Hero;
29    // 
30    //
31    // Here we access the global var reference.
32    //  
33    public helloString: string="hello " + myGlobals.sep + " there";
34
35         ...

37        }
38    }
