I'm trying to use AOT in Angular 2 using webpack and @ngtools/webpack.
I don't have any error with the compilation, but when I open the site on the browser I get a console error:
No NgModule metadata found for 'AppModule'
My AotPlugin on webpack configuration is this:
new AotPlugin({ tsConfigPath: 'tsconfig.json', entryModule: helpers.root('src/app/app.module.ts#AppModule') }) My app.module.ts is:
@NgModule({ bootstrap: [ App ], imports: [ // import Angular's modules BrowserModule, RouterModule.forRoot(ROUTES), SharedModule ], declarations: [ App, HomeComponent, ], providers: providers }) export class AppModule {} and my main.browser.ts:
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; import { AppModule } from "./app/app.module"; const platform = platformBrowserDynamic(); platform.bootstrapModule(AppModule); My tsconfig.json:
