What is the correct way to share the result of an Angular Http network call in RxJs 5?

Question

By using Http, we call a method that does a network call and returns an http observable:

getCustomer() {
    return          


        

Answer 1

according to this article

It turns out we can easily add caching to the observable by adding publishReplay(1) and refCount.

so inside if statements just append

.publishReplay(1)
.refCount();

to .map(...)
