How to determine if a module should be imported into CoreModule or SharedModule

Question

In an application with angular 4, given the following modules:

• ReactiveFormsModule,
• FormsModule,
• HttpModule,
• TranslateModule, (translation module)
• AgGridModule.withComponents ([]), (table structure)
• DatepickerModule.forRoot (), (and generally ngx-bootstrap modules)

Where is the right place to import them: CoreModule or SharedModule ?

Thanks in advance

Answer 1

It depends on:

• these modules define declared types: components, directives or channels.
• general module used for lazy loading

Answer 4

.

:

, : " ", .

In order to display warnings both on the OR pages and in the models, I would like to place this component both in the application component and in any modalities.

This alert component is also associated with a service that receives alert messages.

I realized that in general, services should be included in the main ones and directives in shared.

But can I import sharedmole also in the app-module, or is this the wrong implementation?

Many thanks
