Angular2 Module: How can i import a service from another module

Adding the module to imports should do

import { ApiClientModule } from './apiClient.module';

@NgModule({
  imports: [
    ApiClientModule,
    CommonModule,
    FormsModule
  ],
  declarations: [
    DailyScheduleComponent,
  ],
  exports: [
    DailyScheduleComponent
  ],
})
export class ClinicDashboardModule {
}

otherwise import the file that contains the service class

import { ClinicFacilityService } from './clinic-facility.service';

There is a clear distinction between @NgModule() imports and TypeScript imports.

If you need to use the class name (ClinicFacilityService) then a TypeScript import of that class is required. This is entirely unrelated to @NgModule()

@NgModule({
  ...
  providers: [
    ClinicFacilityService
  ],

If the @NgModule() import is required, then the class name of the module class (ApiClientModule) requires a TypeScript import because the module needs to be passed.

@NgModule({
  imports: [
    ApiClientModule,
  ],

• TypeScript imports are to to uniquely identify a class.
• NgModule imports are to define that a module depends on another module.
