### 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'
    }
  }
});

import {bootstrap} from 'angular2/platform/browser';
import {MyComponent} from './mycomponent';

bootstrap(MyComponent);

import {Component} from 'angular2/core';

import {GithubNames} from './github';

@Component({
  selector: 'my-component',
  template: `
  <button (click)="fetch()">Fetch users</button>
  <ul>
    <li *ngFor="#user of users">
      {{user.login}} <img [src]="user.avatar_url" height="50px">
    </li>
  </ul>
  `,
  providers: [GithubNames]
})
export class MyComponent {
  constructor(private github: GithubNames) {}
  
  fetch() {
    this.github.getUsers().then((users) => {
      this.users = users;
    });
  }
}

export class GithubNames {
  getUsers() {
    return fetch('https://api.github.com/users').then(function(response) {
      return response.json();
    });
  }
