Handling service discovery in Angular

I'm playing around with Microservices at the moment and I also just started using Angular. Now, I am wondering whether/how it is possible to access a service discovery (e.g. Consul) from within Angular? By accessing I mean:

To express this a bit more precisely: There was one use case, in which I developed two simple services using Spring Boot, I applied the steps from this Blog to access one service from the other using Consul. Thus, my REST call looks in the end like this:

restTemplate.getForObject(http://city-service/rest/city/capital', ...);

What I like about this is that I can abstract away from the host and the port information. Right now, I would like to do the same thing in Angular. Hence, instead of something like this:

this.http.get('http://localhost:8080/rest/city/capital')

I would like to have something similar to this:

this.http.get('http://city-service/rest/city/capital')

How can I access a service discovery such as Consul (it does not have to be Consul, other ones are fine too) in Angular? As I said, I just started getting to know Angular, so please excuse if this is a stupid question.

I know that some service discoveries (including Consul) provide a REST API to retrieve information about the registered services. However, then I would first need to send a REST request to this explicitly before I could send my actual wanted REST request. I would prefer if there would be another option. Any help is appreciated.

I posted a more general question concerning this before, but I now concretized the question here.

Consul and other service discovery systems are not designed to be accessible from public web and your question isn't really related to Angular.

You can use a Consul aware load balancer such as https://github.com/fabiolb/fabio or https://traefik.io/ to have traffic routed to services which are registered in Consul according to HOST and/or PATH.
