Given a Nest.js service, determine if the `libraryService` property is injected via property-based injection.

Question

Take a look at the following code for a Nest.js service:

```ts
@Injectable()
export class MyService {
  @Inject('LibraryService')
  private libraryService: LibraryService;
}
```

Which of the following statements is true about this code?

Accepted Answer

`libraryService` is a property of `MyService` where `LibraryService` is injected via property-based injection.

Answer

The code will generate an error because `@Inject()` can only be used in constructors.

Answer

LibraryService' is a class which must be defined in the same module as 'MyService'.

Answer

LibraryService` is an alias for another service that will be automatically resolved by Nest.js.
