Angular 4: factory component not found, have you added it to @ NgModule.entryComponents?

Question

I am using an Angular 4 template with a web package and I get this error when I try to use the (ConfirmComponent) component:

No component factory was found for ConfirmComponent. Have you added it to @ NgModule.entryComponents?

Component declared in app.module.server.ts

@NgModule({
  bootstrap: [ AppComponent ],
  imports: [
    // ...
  ],
  entryComponents: [
    ConfirmComponent,
  ],
})
export class AppModule { }

I also have app.module.browser.tsandapp.module.shared.ts

How can i fix this?

Answer 1

Add this to your module.ts,

declarations: [
  AppComponent,
  ConfirmComponent
]

if the ConfirmComponent is in another module, you need to export it there so that you can use it outside, add:

exports: [ ConfirmComponent ]

ComponentFactory entryComponents:

declarations: [
  AppComponent,
  ConfirmComponent
],
entryComponents: [ConfirmComponent],
