          I found a way to make a shareable Object :



          create new service called GlobaleVariable.ts
          and write this on it :



          @Injectable()
          export class GlobalVariblesClass {
          sharedCategory$ = new ReplaySubject<Groups>(1);

          updateCategoryValue(g: Groups) {

          return this.sharedCategory$.next(g);
          }
          }


          then you can inject this class in any Component Constructor to use it :)
