provideBreadcrumbConfig

Description#

Application-root configuration cascade for the breadcrumb family. Pass any combination of withBreadcrumbAriaLabels, withBreadcrumbDataKey, withBreadcrumbIconKey, and withBreadcrumbSkin features in bootstrapApplication's providers array.

Resolution priority (high -> low):

1. Per-instance Input binding.
2. provideBreadcrumbConfigAt(...) in a parent component's viewProviders.
3. provideBreadcrumbConfig(...) at the application root.
4. Library defaults (CNGX_BREADCRUMB_DEFAULTS).

The provider deep-merges supplied features with the library defaults so consumers only declare keys they want to override.

bootstrapApplication(AppComponent, {
  providers: [
    provideBreadcrumbConfig(
      withBreadcrumbAriaLabels({ bar: 'Navigation trail' }),
      withBreadcrumbDataKey('crumb'),
    ),
  ],
});
