Explain the concept of "HATEOAS" in REST.

Short answer: HATEOAS (Hypermedia As The Engine Of Application State) means responses contain links to related actions/resources. 👉

Example code

{ "id": 1, "name": "John", "links": [ { "rel": "self", "href": "/users/1" }, { "rel": "orders", "href": "/users/1/orders" } } This helps clients navigate APIs dynamically.

Real-world example (ShopNest)

Creating an order is POST /api/orders → 201 with Location header. Fetching is GET /api/orders/{id} → 200 or 404.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
