Angular6 and Hydra

Hello everyone

forgive my english, I hope to make me understand, the contact because I am currently developing a SPA with angular 6 and api-platform my problem is that I do not find how to correctly control the answers in Hydra Vocabulary, so looking for a lot and finding almost no information in internet, come to this group, if someone has come to work with a current version of Angular and api-platform I would be very grateful if you could tell me how I create your services to consume the API

Greetings from Colombia to all
