### Angular2 Starter Plunker - Typescript

A simple plunker demonstrating Angular2 usage:
- 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, FORM_BINDINGS} from 'angular2/angular2'
import {App} from './app'

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

//our root app component
import {
  Component,
  View,
  FORM_BINDINGS,
  FORM_DIRECTIVES,
  ControlGroup,
  FormBuilder,
  Validators
} from 'angular2/angular2'



@Component({
  selector: 'my-app',
  viewBindings: [FORM_BINDINGS]
})
@View({
  template: `
    <form [ng-form-model]="userInputForm">
      <p>Name <input ng-control="name"></p>
      <div ng-control-group="address">
        <p>address line 1 <input type="password" ng-control="addressLine1"></p>
        <p>city <input type="text" ng-control="city"></p>
        <p>state <input type="text" ng-control="state"></p>
        <p>zip <input type="text" ng-control="zip"></p>
      </div>

      <div ng-control-group="passwordRetry">
        <p>Password <input type="password" ng-control="password"></p>
        <p>Confirm password <input type="password" ng-control="passwordConfirmation"></p>
      </div>
    </form>
    <h3>Form value:</h3>
    <pre>{{value}}</pre>
  `,
  directives: [FORM_DIRECTIVES]
})
export class App {
  userInputForm: ControlGroup;
  taskList = [{name:"new task",completed:false}]

  constructor(builder: FormBuilder) {
    this.userInputForm = builder.group({
      name: ["", Validators.required],
      address: builder.group({
        addressLine1 : ["", Validators.required],
        city: ["", Validators.required],
        state: ["", Validators.required],
        zip: ["", Validators.required]
      }),

      passwordRetry: builder.group({
        password: ["", Validators.required],
        passwordConfirmation: ["", Validators.required]
      })
    });
  }
  
  addTask() {
    this.taskList.push({name:"new task",completed:false})
  }
  
  get value(): string {
    return JSON.stringify(this.userInputForm.value, null, 2);
  }
}
