Angular EXCEPTION: No provider for Http

Import the HttpModule

import { HttpModule } from '@angular/http';

@NgModule({
    imports: [ BrowserModule, HttpModule ],
    providers: [],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
export default class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

Ideally, you split up this code in two separate files.
