How to use Spring REST HATEOAS from Angular?

I was learning about Spring REST HATEOAS. But, I am confused about how we use it on the client end..

I mean, let's say I want write a client app using Angular JS. So now I don't have to hardcode the URL's to make REST API calls? And instead i'd use the "rel" attribute that gets returned?

for example, from angular JS,

  • I'd use the root URL "/products"
  • It returns links to individual products (Which I believe will be populated on UI)
  • User selects a product and angular will fetch the product details, along with relevant links to that product to delete, edit, etc..
  • If user clicks on delete, Angualar will use the URI specified in "rel=delete" to delete that product..

Is my understanding correct? Is there a sample angular code, that doesn't hardcode URI but use the rel attribute?

Well you can use any client side API and extract the links from the json as required or use a more specialised client library such as github.com/2muchcoffeecom/ngx-restangular - Alan Hay
Thanks! But, does client API get the URI based on 'rel=delete' attribute? If so, I assume the server side is expected to not change the 'rel' attribute as client will be hard coding it? - rakesh mehra
