It demostrates bi-directional JSON transport to a simple service capable of caching arbitrary JSON objects by id. To run the example, type: $ node json-cache.js That will start the server running. It will tell you a URL of a test page that uses jQuery to consume the service. You can then use the put() and get() calls to cache JSON objects. Objects persist only in memory in the server process, and are lost when the server stops. From my point of view, the interesting part is the transport: serializing, deserializing, GETing, and POSTing with correct MIME types and basic error handling, both server-to-client and client-to-server.
