Here are some key things to bear in mind regarding this particular type of Observables returned by the HTTP module: if we don't subscribe to these observables, nothing will happen if we subscribe multiple times to these observables, multiple HTTP requests will be triggered see this post for more details This particular type of Observables are single-value streams: If the HTTP request is successful, these observables will emit only one value and then complete these observables will emit an error if the HTTP request fails, more on this later With this in mind, let's have a look at some of the most common tasks that we will come across using the HTTP library.
