Can lazy-loaded modules share the same instance of a service provided by their parent?

Question

I\'ve just run into a problem with a lazy-loaded module where parent and child module both require the same service but create an instance each. The declaration is identical

Answer 1

I have a separate layout module with a service, this service needed to work on other feature modules, using lazy load

I was able to solve the problem by exporting the service, straight from the layout module

@NgModule({
    declarations: [...],
    imports: [...],
    exports: [...],
})
export class LayoutModule {
    ...
}

export { LayoutService }
