  *NgModule-level* providers can be specified with `@NgModule()` `providers` metadata option, or in the `@Injectable()` `providedIn` option (with some module other than the root `AppModule`).
  -Use the `@NgModule()` `provides` option if a module is [lazy loaded](guide/lazy-loading-ngmodules). The module's own injector is configured with the provider when that module is loaded, and Angular can inject the corresponding services in any class it creates in that module. If you use the `@Injectable()` option `providedIn: MyLazyloadModule`, the provider could be shaken out at compile time, if it is not used anywhere else in the app.
