Fortune.js is a framework in Node.js language. This framework can prototype hypermedia APIs with JSON protocol. Some of the available resources include guides, docs, examples, and issue management. Particularly, the guide shows instructional procedures that help to create applications. For example, the specifications sections of defining resources, defining association between resources, before and after associations within resources, and advanced usage aim to differentiate the purpose of the framework. In this case, Fortune.js is not an MVC framework, but a JSON view response specified by the JSON API spec.
