According to Angular's upgrade guide, a hybrid Angular 1+2 app is set up like so:
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
platformBrowserDynamic().bootstrapModule(MyAngular2NgModule).then(platformRef => {
const upgrade = platformRef.injector.get(UpgradeModule) as UpgradeModule;
upgrade.bootstrap(document.body, ['myAngular1ModuleName'], {strictDi: true});
});
This code will wire up the application as Angular2, bootstrap the initial component, and THEN wire up the Angular1 app.
The problem is when you have Angular 1 components outside of the <router-outlet>
, <ng-view>
, or <ui-view>
. Angular will try to bootstrap thos components BEFORE Angular1 is wired up. This results in the following error:
TypeError: Cannot read property 'get' of undefined

Here is my Bootstrapped component's HTML:
<section id="panel" className="something">
<sb-header></sb-header>
<main class="page-content" ui-view></main>
<router-outlet></router-outlet>
<sb-footer></sb-footer>
</section>
<sb-app-home></sb-app-home>
<sb-app-nav></sb-app-nav>
sb-app-home is my Angular 1 element. Here is how it is registered in the Angular 2 module:
@Directive({
selector: 'sb-app-home'
})
export class AppHomeDirective extends UpgradeComponent {
constructor(elementRef: ElementRef, injector: Injector) {
super('sbAppHome', elementRef, injector);
}
}
@NgModule({
imports: [
AppRoutingModule,
BrowserModule,
ClientModule,
ClientRoutingModule,
CoreModule,
SubcontractorModule,
UpgradeModule
],
declarations: [
AppComponent,
AppFooterComponent,
AppHeaderComponent,
AppLayoutComponent,
AppNavComponent,
AppHomeDirective
],
providers: [],
bootstrap: [ AppComponent ]
})
export class AppModule {
constructor(public upgrade: UpgradeModule) { }
}
How do I get Angular 1 components to work outside of a route for nav/layout/etc?
