linkNgModule

      
      providers?: Provider[]
    

Defines the set of injectable objects that are available in the injector of this module.

linkSimple Example

Here is an example of a class that can be injected:

      
        content_copy
      
      class Greeter {
   greet(name:string) {
     return 'Hello ' + name + '!';
   }
}

@NgModule({
  providers: [
    Greeter
  ]
})
class HelloWorld {
  greeter:Greeter;

  constructor(greeter:Greeter) {
    this.greeter = greeter;
  }
}
    

      
      declarations?: Array<Type<any> | any[]>
    

Specifies a list of directives/pipes that belong to this module.

linkExample

      
        content_copy
      
      @NgModule({
  declarations: [NgFor]
})
class CommonModule {
}
    

      
      imports?: Array<Type<any> | ModuleWithProviders | any[]>
    

Specifies a list of modules whose exported directives/pipes should be available to templates in this module. This can also contain ModuleWithProviders.

linkExample

      
        content_copy
      
      @NgModule({
  imports: [CommonModule]
})
class MainModule {
}
    

      
      exports?: Array<Type<any> | any[]>
    

Specifies a list of directives/pipes/modules that can be used within the template of any component that is part of an Angular module that imports this Angular module.

linkExample

      
        content_copy
      
      @NgModule({
  exports: [NgFor]
})
class CommonModule {
}
    

      
      entryComponents?: Array<Type<any> | any[]>
    

Specifies a list of components that should be compiled when this module is defined. For each component listed here, Angular will create a ComponentFactory and store it in the ComponentFactoryResolver.

      
      bootstrap?: Array<Type<any> | any[]>
    

Defines the components that should be bootstrapped when this module is bootstrapped. The components listed here will automatically be added to entryComponents.

      
      schemas?: Array<SchemaMetadata | any[]>
    

Elements and properties that are not Angular components nor directives have to be declared in the schema.

Available schemas:

• NO_ERRORS_SCHEMA: any elements and properties are allowed,
• CUSTOM_ELEMENTS_SCHEMA: any custom elements (tag name has "-") with any properties are allowed.

      
      id?: string
    

An opaque ID for this module, e.g. a name or a path. Used to identify modules in getModuleFactory. If left undefined, the NgModule will not be registered with getModuleFactory.
