What is the best way to incorporate a service that needs to be accessible throughout the entire app in Angular 2?

As I embark on creating the NewService, my goal is to enable its accessibility from various parts of the application.

The question arises - should I inject it in SharedModule (a module that exports all reusable modules) or in AppModule (the primary module of my application)?

@NgModule({

  providers: [
     // Where is the optimal placement for injection?
  ]
})

Answer №1

Whether you include it in the AppModule directly or in a feature module is irrelevant, as long as the module is not being lazy loaded.

Modules that are lazy loaded have their own unique root scope, meaning providers added there are only accessible within the lazy loaded module.
