### Angular2 Chicken Plunker - Typescript - Alpha .42

A simple plunker demonstrating Angular2 chickens:
- Uses SystemJS + TypeScript to compile on the fly
- Includes binding, directives, 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/angular2';
import {HTTP_BINDINGS} from 'angular2/http';
import {App} from './app';

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

//our root app component
import {Component, View, CORE_DIRECTIVES} from 'angular2/angular2'
import {ChickensService} from './chickensService'
import {Chicken} from './chicken'

@Component({
  selector: 'app',
  providers: [ChickensService]
})
@View({
  template: `
    <div>
      <h2>Angular2 Chickens!</h2>
      <chicken 
        *ng-for="#chicken of chickens" 
        [name]="chicken.name"
        (hello)="saidHello($event)">
      </chicken>
    </div>
  `,
  directives: [CORE_DIRECTIVES, Chicken]
})
export class App {
  constructor(public chickensService:ChickensService) {
    chickensService.chickens
      .subscribe(chickens => this.chickens = chickens);
  }
  saidHello($event){
    alert(`You said hello to ${$event}`)
  }
}

//a simple chickens service
import {Injectable} from 'angular2/angular2';
import {Http} from 'angular2/http';

@Injectable()
export class ChickensService {
  constructor(http:Http) {
    this.chickens = http.get('api/chickens.json').map(res => res.json());
  }
}

//a simple chicken component
import {Component, View, EventEmitter} from 'angular2/angular2'

@Component({
  selector: 'chicken',
  inputs: ['name'],
  outputs: ['hello']
})
@View({
  template: `
    <div>
      <span>{{name}}</span>
      <button (click)="sayHello()">Say Hello</button>
    </div>
  `
})
export class Chicken {
  hello = new EventEmitter();
  sayHello(e) {
    this.hello.next(this.name);
  }
}
