Angular2 Starter Plunker - Typescript - RC.0

A simple plunker demonstrating Angular2 usage:

• Uses SystemJS + TypeScript to compile on the fly
• Includes binding, directives, http, pipes, and DI usage.

For opening

app.ts

//our root app component
import {Component, NgModule} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'
import { RouterModule }  from '@angular/router';

import { HtmlOutlet } from './html-outlet';
import { SharedModule } from './shared.module'
@Component({
  selector: 'my-app',
  template: `<router-outlet></router-outlet>`
})
export class AppComponent {}


@Component({
  selector: 'my-home',
  template: `
    <h1>home</h1>
    <html-outlet [html]="value"></html-outlet>
  `
})
export class HomeComponent {
  value = `<span>Test interpolation {{5 + 6}}</span>
   <div><a routerLink="/about">To about</a><my-test></my-test></div>`;
}




@Component({
  selector: 'my-about',
  template: `
    <a routerLink="/">To home</a>
  `
})
export class AboutComponent {}

@NgModule({
  imports:      [ 
    BrowserModule,
    RouterModule.forRoot([
      { path: '', component: HomeComponent },
      { path: 'about', component: AboutComponent }

    SharedModule
    ],
  exports: [HomeComponent, AboutComponent],
  declarations: [ AppComponent, HtmlOutlet, HomeComponent, AboutComponent ],
  bootstrap:    [ AppComponent ]
})
