nullinjectorerror no provider for store if importing the store module from a child module

Question

In my app.module.ts file I set up a store with:

imports: [
  StoreModule.forRoot(
    { soundtrackState: soundtrackReducer }
  ),
  EffectsModule.forRoot(
    [
      // SoundtrackEffects TODO add some effects
    ]
  ),
  StoreDevtoolsModule.instrument({ maxAge: 15, logOnly: environment.production }),    
  CoreModule,

Now, if I move this code out and into the core.module.ts file then I get the nullinjectorerror no provider for store error.

Answer 1

for any other module that root you need to use forFeature and I guess app.module' store should be initialized with code you wrote.

@NgModule({
  declarations: [

  ],
  imports: [
    EffectsModule.forFeature(groupModuleEffects),
    StoreModule.forFeature(GROUPS_FEATURE_NAME, groupModuleReducers),
    StoreDevtoolsModule.instrument({ maxAge: 25, logOnly: environment.production }),
    SharedModule
  ],
  providers: []
})
export class GroupsModule {}
