### 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 {ObjectViewComponent} from './object-view.component'

@Component({
  selector: 'my-app',
  templateUrl: './my-template.html',
  directives: [ObjectViewComponent]
})
export class App {
  private object: any = {
    string: 'string',
    boolean: true,
    number: 0,
    array: ['a', 'b', 'c'],
    object: {
      prop1: 'prop1',
      prop2: 100
      prop3: {
        array: ['999', '998', '997']
      }
    }
  }
}

import {Component, Input} from 'angular2/core'

@Component({
  selector: 'object-view',
  template: `<ul>
      <li *ngFor="#property of getKeys()">
        {{property}}: 
        <span *ngIf="!isObject(property)">
          {{getValue(property)}}
        </span>
        <span *ngIf="isObject(property)">
          <object-view [object]="getValue(property)"></object-view>
        </span>
      </li>
    </ul>`,
  directives: [ObjectViewComponent]
})
export class ObjectViewComponent {
  @Input() object: any;
  
  private getKeys(): string[] {
    return Object.keys(this.object);
  }
  
  private getValue(property: string): any {
    return this.object[property];
  }
  
  private isObject(property: string): boolean {
    const value = this.getValue(property);
    return !Array.isArray(value) && typeof value === 'object';
  }
}
