"Encountering Issues with Angular's Modules and EntryComponents during Lazy Loading

Upon lazy loading an Angular module, I encountered an issue when trying to open my DatesModal that resulted in the following error:

No component factory found for DatesModal. Have you included it in @NgModule.entryComponents?

The declaration and entryComponents sections of my lazyModule are defined as follows:

declarations: [DatesModal]
entryComponents: [DatesModal]

I have made sure to include DatesModal in the entryComponents array of the lazyModule. Can anyone suggest what might be causing this error?

If more information is needed to address this question, please feel free to ask.

Answer №1

It seems like you are trying to use or import a module in other modules, but this particular module is not accessible to others. To resolve this, try exporting your module:

exports: [DatesModal]

UPDATE:

According to the Angular documentation:

In production applications, it's important to minimize the amount of code loaded. Only include classes that are actually needed and exclude components that are never used. The Angular compiler only generates code for components reachable from entryComponents; Therefore, adding more references to @NgModule.declarations does not guarantee inclusion in the final bundle. If a component isn't an entry component and isn't found in a template, the tree shaker will discard it. It's recommended to only add components that are truly entry components to optimize app size.

To enable lazy loading for your module, make changes in routes like this:

const routes: Routes = [
  {
    path: 'customers',
    loadChildren: () => import('./customers/customers.module').then(mod => mod.CustomersModule)
  },
  {
    path: 'orders',
    loadChildren: () => import('./orders/orders.module').then(mod => mod.OrdersModule)
  },
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
];

Answer №2

Did you utilize a third-party library or your own code to dynamically create this component within a lazy-loaded module?

If yes, make sure to include this component in the AppModule's (or another non-lazy-loaded module) entrycomponents.
