You have to add your value in the providers of the AppModule:

@NgModule({
   imports: [ BrowserModule, FormsModule, HttpModule],
   declarations: [ AppComponent ],                
   providers: [
                 DataService,
                 {provide: 'rootVar', useValue: rootVar}
              ], 
   bootstrap: [ AppComponent ]
  })
 export class AppModule {}

Now you should be able to access the value in your components and services:

export class MyComponent {
    constructor(@Inject('rootVar') rootVar) {}
}
