Angular 2 router no base href set

I had faced similar issue with Angular4 and Jasmine unit tests; below given solution worked for me

Add below import statement

import { APP_BASE_HREF } from '@angular/common';

Add below statement for TestBed configuration:

TestBed.configureTestingModule({
    providers: [
        { provide: APP_BASE_HREF, useValue : '/' }
    ]
})

https://angular.io/docs/ts/latest/guide/router.html

Add the base element just after the <head> tag. If the app folder is the application root, as it is for our application, set the href value exactly as shown here.

The <base href="/"> tells the Angular router what is the static part of the URL. The router then only modifies the remaining part of the URL.

<head>
  <base href="/">
  ...
</head>

Alternatively add

>= Angular2 RC.6

import {APP_BASE_HREF} from '@angular/common';

@NgModule({
  declarations: [AppComponent],
  imports: [routing /* or RouterModule */], 
  providers: [{provide: APP_BASE_HREF, useValue : '/' }]
]);

in your bootstrap.

In older versions the imports had to be like

< Angular2 RC.6

import {APP_BASE_HREF} from '@angular/common';
bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  {provide: APP_BASE_HREF, useValue : '/' });
]);

< RC.0

import {provide} from 'angular2/core';
bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  provide(APP_BASE_HREF, {useValue : '/' });
]);

< beta.17

import {APP_BASE_HREF} from 'angular2/router';

>= beta.17

import {APP_BASE_HREF} from 'angular2/platform/common';

See also Location and HashLocationStrategy stopped working in beta.16


Angular 7,8 fix is in app.module.ts 

import {APP_BASE_HREF} from '@angular/common';

inside @NgModule add

providers: [{provide: APP_BASE_HREF, useValue: '/'}]
