API

  
    const APP_BASE_HREF: InjectionToken<string>;

Usage Notes

The following example shows how to use this token to configure the root app injector with a base href value, so that the DI framework can supply the dependency anywhere in the app.

          import {NgModule} from '@angular/core';import {APP_BASE_HREF} from '@angular/common';@NgModule({  providers: [{provide: APP_BASE_HREF, useValue: '/my/app'}]})class AppModule {}
