ng-modules

问题 I want to have a loaded module configurable. In theory, I want a module that is its own bigger application do receive some configuration.

I tried and searched around and have not seen the usage of something like: children: [ { path: 'application-module', loadChildren: () => import('@application-module').then(m => m.ApplicationModule.forRoot({

问题 I need to send a configuration (array of objects) to a service in a feature module and this configuration needs to be dynamically calculated.

问题 I'm wondering if it's better to create one single module that contains all my angular 2 code or if it is better to split everything across multiple modules. For example, I'm creating my blog with Angular 2. So I have a "article-list" component and an "article" one.

The "article" component contains a "tag-list" component (that follows the same pattern as the "article

问题 I am getting the following error "Can't bind to 'ngSwitchWhen' since it isn't a known property of 'template'." I've read different topics where it was advised to add import { CommonModule } from '@angular/common' and add "CommonModule" into the imports section of @NgModel, which I did, however this did not solve the problem.

Any ideas? 回答1: You can't add FormGroup to module's imports, just import it in the component in which you want to use FormGroup .

问题 I've been trying to create an @NgModule (named ModelsModule ) made of objects like User, Book, Library, Movie, and so on.
