How to share an instance among the entire Angular application?

Question

Angular

The root component <app-root>has an input property `@Input() props`.

In the component's constructor, this property is read and the third-party map (class) is initialized:

export class MapComponent implements AfterContentInit {

     public map: Map;
    @Input() props: MapProps = {};

     constructor() {
         this.map = new Map(this.props)
    }
}

How to share the resulting map this.map = new Map()among the entire Angular application?
