SharePoint App with Angular2

Using a tutorial I created a SharePoint App with Angular2.  It deploys but has problems.

Here is the link to the tutorial:
Tutorial Link
I carefully copied all the code and the app deploys, but the "hello world" message doesn't show up and I get an error in VS2015 IDE which I will include next followed by the TS file and the JS file.

The JS File:
System.register(["./app.module", "angular2/core"], function (exports_1, context_1) {
    "use strict";
    var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {
        var c = arguments.length, r = c < 3 ? target : desc === null ? desc = Object.getOwnPropertyDescriptor(target, key) : desc, d;
        if (typeof Reflect === "object" && typeof Reflect.decorate === "function") r = Reflect.decorate(decorators, target, key, desc);
        else for (var i = decorators.length - 1; i >= 0; i--) if (d = decorators[i]) r = (c < 3 ? d(r) : c > 3 ? d(target, key, r) : d(target, key)) || r;
        return c > 3 && r && Object.defineProperty(target, key, r), r;
    };
    var __metadata = (this && this.__metadata) || function (k, v) {
        if (typeof Reflect === "object" && typeof Reflect.metadata === "function") return Reflect.metadata(k, v);
    };
    var __moduleName = context_1 && context_1.id;
    var app_module_1, core_1, AppComponent;
    return {
        setters: [
            function (app_module_1_1) {
                app_module_1 = app_module_1_1;
            },
            function (core_1_1) {
                core_1 = core_1_1;
            }
        ],
        execute: function () {
            AppComponent = class AppComponent {
            };
            AppComponent = __decorate([
                core_1.Component({
                    selector: 'app-main',
                    template: `<h1>${app_module_1.Welcome.getMessage()}</h1>`
                }),
                __metadata("design:paramtypes", [])
            ], AppComponent);
            exports_1("AppComponent", AppComponent);
        }
    };
});
//# sourceMappingURL=app.component.js.map

Open in new window


The TS File:
import {Welcome} from './app.module'
import {Component} from 'angular2/core'

@Component({
    selector: 'app-main',
    template: `<h1>${Welcome.getMessage()}</h1>`
})

export class AppComponent { }

Open in new window


Please advise.
