Sets up providers necessary to enable hydration functionality for the application.

By default, the function enables the recommended set of features for the optimal performance for most of the applications. It includes the following features:

• Reconciling DOM hydration. Learn more about it here.
• HttpClient response caching while running on the server and transferring this cache to the client to avoid extra HTTP requests. Learn more about data caching here.

These functions allow you to disable some of the default features or enable new ones:

• withNoHttpTransferCache to disable HTTP transfer cache
• withHttpTransferCacheOptions to configure some HTTP transfer cache options
• withI18nSupport to enable hydration support for i18n blocks
• withEventReplay to enable support for replaying user events

Basic example of how you can enable hydration in your application when bootstrapApplication function is used:

bootstrapApplication(AppComponent, {
  providers: [provideClientHydration()]
});

Alternatively if you are using NgModules, you would add provideClientHydration to your root app module's provider list.

@NgModule({
  declarations: [RootCmp],
  bootstrap: [RootCmp],
  providers: [provideClientHydration()],
})
export class AppModule {}
