const
A predefined DI token for the base href to be used with the PathLocationStrategy
. The base href is the URL prefix that should be preserved when generating and recognizing URLs.
const APP_BASE_HREF: InjectionToken<string>;
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 {Component, NgModule} from '@angular/core'; import {APP_BASE_HREF} from '@angular/common'; @NgModule({ providers: [{provide: APP_BASE_HREF, useValue: '/my/app'}] }) class AppModule {}
