### Angular2 Starter Plunker - Typescript - Beta 0

A simple plunker demonstrating Angular2 usage:
- Uses SystemJS + TypeScript to compile on the fly
- Includes binding, directives, http, pipes, and DI usage.

System.config({
  //use typescript for compilation
  transpiler: 'typescript',
  //typescript compiler options
  typescriptOptions: {
    emitDecoratorMetadata: true
  },
  //map tells the System loader where to look for things
  map: {
    app: "./src"
  },
  //packages defines our app package
  packages: {
    app: {
      main: './main.ts',
      defaultExtension: 'ts'
    }
  }
});

//main entry point
import {bootstrap} from 'angular2/platform/browser';
import {App} from './app';

bootstrap(App, [])
  .catch(err => console.error(err));

//our root app component
import {Component} from 'angular2/core';
import {Person} from './person';
@Component({
  selector: 'my-app',
  providers: [],
  template: `
    <ul>
      <li *ngFor="#person of people">
      <span><b>{{person?.lastName}}</b> {{person?.firstName}}</span>
      <ul>
        <li>Profession: <span>{{person?.profession?.caption || 'not provided'}}</span></li>
        <li *ngIf="person.children.length">Kids:</li>
        <ul>
        
        <li *ngFor="#child of person.children">
          <span>His/Her firstname is <b>{{child?.firstName ||"not decided"}}</b></span>
        </li>
        </ul>
        
      </ul>
    </li>
    </ul>
