Using cache operator for Observables

Question

I am following some tutorials from angular-university and in a video they suggest to use cache() operator to avoid multiple requests. So I tried with the following:

this.posts$ = this.postsService.savePost(post)
    .switchMap(() => this.postsService.getPosts())
    .publishReplay(1)
    .refCount();

and it works but I prefer cache() instead of publishReplay The naive way to achieve this is:

this.postsService.savePost(post)
    .subscribe(() => this.postsService.getPosts())

but it is not kind of reactive.

So I prefer to use cache but I could not find this on the add operators.

Currently I am using rxjs: 5.4.3.

So, is cache supported by the version I am currently using?
