How can I implement lazy loading with Angular Universal for SSR?

To implement lazy loading with Angular Universal, you need to configure your routes to use the loadChildren property. This allows modules to be loaded on demand.

Can you provide an example of how to set this up in my Angular app?

Sure! First, create a feature module and then in your routing module, use the following syntax:

const routes: Routes = [
  { path: 'feature', loadChildren: () => import('./feature/feature.module').then(m => m.FeatureModule) }
];

This will ensure that the feature module is loaded only when the user navigates to the 'feature' route.

What about the server-side rendering part? Do I need to do anything special?

Yes, for server-side rendering, ensure that your lazy-loaded modules are compatible with Angular Universal. You may need to use the TransferState service to manage state between the server and client.

Are there any performance considerations I should keep in mind?

Absolutely! While lazy loading improves initial load time, ensure that your modules are not too large, as this can lead to longer load times when they are requested. Optimize your modules and consider using preloading strategies.
