withNavigationErrorHandler

Provides a function which is called when a navigation error occurs.

This function is run inside application's injection context so you can use the inject function.

This function can return a RedirectCommand to convert the error to a redirect, similar to returning a UrlTree or RedirectCommand from a guard. This will also prevent the Router from emitting NavigationError; it will instead emit NavigationCancel with code NavigationCancellationCode.Redirect. Return values other than RedirectCommand are ignored and do not change any behavior with respect to how the Router handles the error.

Basic example of how you can use the error handler option:

const appRoutes: Routes = [];
bootstrapApplication(AppComponent,
  {
    providers: [
      provideRouter(appRoutes, withNavigationErrorHandler((e: NavigationError) =>
inject(MyErrorTracker).trackError(e)))
    ]
  }
);
