Creating a Simple Angular 2 Example

1. Create a simple template(Download a template of angular2 with gulp from https://github.com/santiago762000/angular-2-env-setup)
2. run npm install to install all the required libraries
3. run npm start to start the service. It will open a browser window to test the application
4. open another window
5. run gulp
6. create a new file named first-example.component.ts
7. import the component library
    import {Component} from "angular/core"
8. Add a decorator
@Component({
  selector:'myTag',
  template:'This is a test'
})
9. Add a component class
export class FirstExampleComponent{
}
first-example.component.ts should be like:
import {Component} from "angular2/core"

@Component({
  selector:'myTag',
  template:'This is a test'
})
export class FirstExampleComponent{

}

10. Open dev/app.components.ts
11. Import FirstExample.component.ts
import {FirstExampleComponent} from "./first-example.component";

12. Add the directives property to @Component with an array of Components that will be used for app.components.ts
directives:[FirstExampleComponent]

13. Modify the template property to show tag
template: '',

app.component.ts should look like:
import {Component} from 'angular2/core';
import {FirstExampleComponent} from "./first-example.component";
@Component({
    selector: 'my-app',
    template: '',
    directives:[FirstExampleComponent]
})
export class AppComponent {
}
14. Check the opened browser on step 3:
