Restfulie
Why would I use restfulie?
1. Easy —> writing hypermedia aware resource based clients
2. Easy —> hypermedia aware resource based services
3. Small -> it’s not a bloated solution with a huge list of APIs
4. HATEOAS —> clients you are unaware of will not bother if you change your URIs
5. HATEOAS —> services that you consume will not affect your software whenever they change part of their flow or URIs
