I followed the steps in the readme and opened the folder in visual studio code but while loading the page
I can see an error and page is not working.

Same problem.
import { Component } from '@angular/core'
@component({
selector: 'wel',
template: `{{name}}
Welcome component
<span (click)="clicked()">
`
})
export class WelcomeComponent {
public name: string;
constructor() {
this.name = 'Test';
}
public clicked(event: any): void {
this.name = 'Pramod';
}
}
As soon as I add Event Binding it is failing other wise it works.
The error comes from zone.js angular/zone.js#832
That is normal, that will install the broken version.
after changing to in package,json "zone.js": "0.8.5" it started working.
