Regarding getting retain values in between two components.

Question

Dear All, 

I have created one component with name Global.ts in Angular 6. I have some variables like LoginUserID and its related some information. I have set data to these variables in my navbar component. What I want is this data which is set in navbar component, should get access in all remaining component.

I am not able to get this data in multiple component because it gets vanished if I am trying to access it from other component.

How can I retain data in between multiple components.

Any sugestions will be acceptable. 

Thanking you in advanced.
